Alkon Rhino Tuff Bins in India: The ARTB Range for Maintenance Stores and Tool Rooms
Rhino Tuff Bins are the reinforced end of the Alkon small-parts family, and the ARTB series exists for one reason: bins that live in a maintenance store, a tool room or a fitter's trolley get handled far more roughly than bins that sit quietly on an assembly-line rack. They get grabbed by the front lip with an oily glove, dropped the last few inches onto a steel shelf, filled with grub screws and dowel pins that weigh far more per litre than plastic clips, and pulled in and out of louvre panels several hundred times a year. This page is a working guide to that range from Shreeram Metafusion Engineers Pvt. Ltd., authorised stockist of ALKON Plastics Pvt. Ltd. for over 30 years, covering how the reinforced construction and stacking rim actually behave, what the label holders are for, how ARTB bins combine with louvre panels and trolleys, where the range sits against the other Alkon bins, and how to specify and maintain a set that will still be readable and square after several years on a shop floor in Navi Mumbai, Pune or Coimbatore.
What the ARTB Series Is, and Why It Is Called Rhino Tuff
The Rhino Tuff range carries the part-code prefix ARTB, and every code in the series follows the same logic: ARTB plus a number that identifies the shell size, starting at ARTB-05. The smallest documented size, ARTB-05, measures 109 x 104 x 49 mm outside and 95 x 89 x 43 mm inside. Read those two sets of numbers side by side, because they are the most informative thing on the whole page. The difference between outside and inside is 14 mm across the length, 15 mm across the width and 6 mm on the depth. That gap is not wasted plastic and it is not a moulding accident. It is where the reinforcement lives: the thickened front lip, the ribbing that runs down the side walls, and the stacking rim that runs around the top edge. A plain open-front bin of the same external footprint would give you a slightly larger cavity and a shell that starts to bow the first time you fill it with steel.
This matters more in a tool room than anywhere else, because the density of what goes into these bins is unlike anything else on the shop floor. A litre of loose polypropylene fasteners weighs a few hundred grams. A litre of M8 hex nuts, mixed washers or carbide inserts weighs several kilos. Buyers who have only ever specified bins for light plastic components tend to size on volume alone and are then surprised when the front face of a cheap bin bellies out within a few months, at which point the bins no longer sit square in the louvre panel and the whole panel starts to look untidy. The ARTB shell is designed around the assumption that it will be loaded heavy and handled hard, which is why the range is normally the right answer for maintenance stores, machine-shop tool cribs and electrical spares cupboards rather than for light kitting.
Like every bin range in the Alkon catalogue, Rhino Tuff bins are moulded in polypropylene copolymer, marked with resin code 05, and rated for a service range of -10C to +70C. They carry food-safe and recyclable marks. Copolymer rather than homopolymer is the relevant detail for a rough-handling range: copolymer PP keeps far more of its impact strength at low temperature and takes repeated flexing at the lip without going brittle. That is the property you are buying when you choose the reinforced range over a lighter one, and it is why an ARTB bin survives being knocked off a bench in an air-conditioned metrology room as well as one in an unconditioned shed in Rajkot in January.
The other thing worth stating plainly at the start is where Rhino Tuff sits in the wider catalogue. Shreeram Metafusion stocks 476+ products across 9 ranges, and ARTB is one range among several that all look, at a glance, like open-front bins. The differences between them are real but they are differences of construction and size ladder, not differences of quality. Choosing correctly is a matter of matching the bin to the handling regime and the part weight, and most of this page is about how to make that call rather than about which range is best.
Reinforced Construction: What Is Actually Reinforced, and Where It Shows Up
When a supplier says a bin is reinforced, the useful question is: reinforced against which failure? Open-front bins fail in four fairly predictable ways, and each one is addressed by a different piece of geometry. The first is front-lip spread, where the open face slowly widens because the bin is repeatedly lifted by the front edge with a full load behind it. The second is side-wall bowing, where the walls bulge outward under the hydrostatic-like pressure of loose granular contents such as washers or ferrules. The third is base sag, where the floor of the bin deflects downward and the bin no longer sits flat on a shelf. The fourth is rim damage, where the top edge that carries the stack above it gets chipped or crushed.
The ARTB shell addresses the first two by thickening and ribbing rather than by simply making the whole wall thicker, which would add cost and weight without adding much stiffness. Stiffness in a moulded box comes from section depth far more than from material thickness, so a rib that stands proud of the wall does more than a wall that is uniformly a millimetre fatter. This is why the wall allowance on ARTB-05 is about 7 mm per side. If you run your thumb down the outside of a Rhino Tuff bin you can feel where the section changes; that is the load path doing its job. The practical consequence for a stores manager is that ARTB bins keep their rectangular plan view when full, which is what allows them to sit shoulder to shoulder in a louvre panel without the row drifting out of alignment.
Base behaviour is where the reinforced ranges most obviously separate from the light ones in day-to-day use. A bin with a sagging floor does two irritating things: it rocks on a flat shelf, and it stops the bin below in a stack from taking load cleanly through its rim. Both are minor on day one and both compound. A rocking bin gets pushed back into place fifty times a day, which is fifty more chances for the label to get scuffed and for the front lip to be grabbed. A stack that transfers load through the middle of a lid-less bin rather than through its rim is a stack that will eventually crush the bin at the bottom. Getting the base right is unglamorous and it is most of the reason the reinforced range costs what it costs.
There is a fifth failure mode that is less about the bin and more about the environment, and it deserves a mention because it catches out buyers in coastal and heavy-industry belts. Polypropylene is chemically indifferent to most of what a general engineering works throws at it, including cutting-oil mist, mild detergents, salt-laden air along the Mumbai and Chennai coasts, and the fine abrasive dust of a grinding section. What it does not love is prolonged direct UV and prolonged heat above its service range. A bin that is stiff and reinforced but has spent two summers on a rack next to a west-facing skylight in Ahmedabad will still be stiff, but it will have lost some of its impact resistance. Reinforcement buys you mechanical margin; it does not exempt you from the environment limits, and the section further down on temperature and chemistry goes into this properly.
The Stacking Rim: How It Works and How People Get It Wrong
The stacking rim is the moulded lip that runs around the top opening of the bin. Its job is twofold. First, it gives the top edge enough section to survive being knocked, dragged and stacked without deforming. Second, and more importantly, it forms a location feature: the base of the bin above nests into or onto the rim of the bin below so that a column of bins locates itself rather than relying on friction. Without a location feature, a stack of open-front bins is a landslide waiting for the first forklift to pass. With one, a column of four or five bins behaves as a single block that you can slide along a shelf with one hand.
The most common error with stacking rims is stacking bins that are not the same size. It sounds obvious written down, but it happens constantly in real stores, particularly during a stock-take when everything comes off the shelf and goes back in a hurry. A larger bin sitting on a smaller one bridges across the rim rather than locating on it, which puts the entire load onto two edges instead of four. That is exactly the loading case that cracks a rim. The rule to write into your stores SOP is simple: a stack is a stack of one part number. If you need mixed sizes in a vertical run, use a shelf or a louvre panel to separate them rather than stacking directly.
The second common error is stacking too high for the contents. Rim strength is finite and it is the weight above that matters, not the number of bins. Four bins of light electrical terminals is a lighter column than two bins of stainless nuts. A workable field rule for maintenance stores is to keep the total column weight modest enough that a single storesperson can lift the top bin off cleanly with one hand while standing flat-footed, because a column that needs a stretch and a two-handed heave is a column that will eventually be pulled over. If you are stacking on the floor rather than on a shelf, keep it lower still, because a floor stack has nothing to stop it toppling sideways.
There is a subtler point about stacking that experienced stores managers already know but that rarely gets written down. Stacked open-front bins are only genuinely useful if the bins below stay accessible, and the open front of a bin in the middle of a column is partly obstructed by the bin above it. In practice this means stacking is excellent for reserve stock and mediocre for active picking. The pattern that works is: active picking faces sit in louvre panels or on shelving at working height; reserve quantities of the same part sit in stacked columns of identical bins on a lower shelf or a pallet position; and the stack exists to be broken down, not picked from. Once you frame the stacking rim as a bulk-handling feature rather than a picking feature, most of the layout decisions become easy.
Label Holders and Why Identification Is the Real Product
Every ARTB bin carries a label-holder provision on the front face, and this is the feature that quietly determines whether your storage system works. A bin is a container; a labelled bin is an address. The difference is the whole of stores discipline. A tool room with 300 unlabelled bins is a place where a fitter spends four minutes finding a split pin. A tool room with 300 labelled bins in a fixed location scheme is a place where he spends fifteen seconds, and where the person covering the second shift can find it too.
The practical advice on labelling is unglamorous but it saves more money than any other decision on this page. Print labels rather than writing them by hand, because hand-written labels are illegible to everyone except the person who wrote them and they disappear when that person moves department. Put three pieces of information on every label as a minimum: the part number as it appears in your ERP or stores register, a short plain-language description in the language your storespeople actually use, and the bin location code. Add a barcode or QR code if your system supports scanning, because the label holder is exactly the right place for it and retrofitting scannable labels later means touching every bin in the store.
Location coding deserves its own paragraph because it is where most small stores go wrong. The instinct is to label bins with the part and let people remember where the bin lives. This works until the store is rearranged, at which point institutional memory evaporates. The better scheme is fixed-location: the shelf or louvre panel position carries a code, the bin carries the same code, and the stores register maps part numbers to codes. When a part is superseded you change the label and the register entry, not the layout. When a new storesperson joins, he needs the register and nothing else. This is precisely why the label holder is moulded into the bin front rather than left to a stuck-on sticker; the holder lets you change the label without leaving adhesive residue and without the label peeling off in an oily environment.
One environment-specific warning. In tool rooms and machine shops the air carries an oil mist that will, over months, creep behind a plain adhesive label and lift it. A label sitting in a moulded holder is mechanically retained, so it survives this. But the label stock still matters: plain paper goes translucent and soft with oil, while a synthetic or laminated stock stays legible. If you are specifying bins for a grinding or honing section in a cluster like Pune's auto-component belt or the machine-shop concentrations around Coimbatore, budget for decent label stock at the same time you budget for bins. It costs very little relative to the bins and it is the difference between a system that reads cleanly in year three and one that does not.
Rhino Tuff Bin Sizes: Reading the ARTB Ladder Correctly
The ARTB series runs as a size ladder, and the useful way to think about a ladder is not as a list of sizes but as a set of decisions about pitch. The published dimension we can quote precisely is ARTB-05: 109 x 104 x 49 mm outside, 95 x 89 x 43 mm inside. That is a compact bin, close to square in plan, and shallow. It suits small high-count items: circlips, dowels, small screws, O-rings, indexable insert boxes, terminal lugs. As you go up the ladder the shells get longer front-to-back and deeper, which changes what they are good for rather than simply making them bigger.
Depth is the dimension people under-think. A deeper bin holds more, but everything in the bottom third of a deep bin is effectively invisible and hard to reach without tipping the bin out. For a maintenance store, where the objective is speed of retrieval rather than density of storage, shallower bins with more faces usually beat deeper bins with fewer faces. The exception is reserve stock, where you are not picking and depth is free capacity. So the sizing rule is: pick shallow for the picking face, deep for the reserve. If you find yourself specifying a deep bin for a fast-moving item, that is usually a signal that the item wants two bins rather than one large one.
Plan area drives something else entirely: how many bins fit on a metre of louvre panel or shelf. This is where the near-square proportion of the small ARTB sizes pays off. A 104 mm wide bin gives you roughly nine picking faces per metre of rail width, allowing for the small gaps you want between bins so that a gloved hand can get in. Widen the bin and the count drops fast. Before you place an order, take the panel or shelf width you actually have, divide by the bin width plus a few millimetres of clearance, and round down. Do that arithmetic for each size in the ladder and you will usually find one or two sizes that fit your existing structure almost exactly and one or two that waste 80 mm at the end of every run.
The stocking implication of a ladder is worth spelling out, because it is a procurement decision rather than an engineering one. Standardising on two or three sizes across a plant is nearly always better than using six. Fewer sizes means stackable columns are always compatible, spare bins from one department can be moved to another, replacements are always available, and the louvre panel layout is a repeated module rather than a jigsaw. When a new line goes in at a second site, you order the same two codes. The temptation to size every bin perfectly to its contents is the single most common cause of stores that look tidy on commissioning day and chaotic three years later.
It also helps to separate the two questions that sizing actually answers, because they get conflated constantly in specification meetings. The first question is how much of a part you want to hold at the picking face, which is a replenishment decision driven by consumption rate and how often the storesperson can realistically top up. The second is how much of that part you want to hold in total, which is an inventory decision driven by lead time and criticality. Confusing the two produces the classic maintenance-store mistake of putting six months of stock into one very large bin at eye level, where it blocks the face, hides the label under an overflowing pile, and makes the bin too heavy to lift down for cleaning. Split the two questions and the sizing answers itself: a modest bin at the face, and a stacked column of the same code in reserve behind or below it.
The rules below hold whichever ARTB code you eventually land on, and they are worth writing into a one-page internal standard so that the next person who extends the store follows the same logic rather than inventing a new one. Most of the drift you see in older stores is not a bad original design; it is a good original design that nobody wrote down, extended by three different people over eight years with no shared rule about how sizes get chosen or where a new part number goes.
- Pick the picking-face size on visibility and reach, not on maximum capacity — if you cannot see the bottom of the bin at eye level, it is too deep for a fast mover.
- Pick the reserve size on cube efficiency, because nobody picks from reserve; they break the stack down.
- Fix the plan width to your existing rail, panel or shelf module so that runs finish flush.
- Standardise on two or three ARTB codes plant-wide rather than a perfect size for every part.
- Where a part has both a fast pick and a bulk holding, use two bins of the same code rather than one larger bin.
- Confirm the exact outside dimensions for the codes you are ordering before you cut or order panels — ARTB-05 at 109 x 104 x 49 mm is the anchor point, and the rest of the ladder should be confirmed against the current catalogue at /downloads.
Louvre Panel Combinations: Building a Wall That Works
Louvre panels are the most common way Rhino bins get mounted, and the combination is genuinely more useful than either part alone. A louvre panel is a sheet with a series of horizontal profiled slots; the back of the bin carries a matching hook. The bin drops onto a louvre and hangs, and it can be moved to a different louvre in seconds without tools. That last property is the whole point. A shelf fixes your layout at the moment you install it; a louvre panel lets the layout follow the work.
The design method for a louvre wall is to work backwards from the picking motion rather than forwards from the wall area. Stand where the person will stand. The zone from roughly waist to shoulder is prime; put the fastest-moving twenty per cent of part numbers there. Below waist and above shoulder is secondary; put slow movers and larger, heavier bins low. Nothing that is picked hourly should require a stretch or a squat, because over a year that adds up to real time and real physical wear. In a maintenance store where the same three fasteners account for half the picks, this single decision does more for productivity than any amount of extra storage.
Panel format is the next decision. Wall-mounted louvre panels are the cheapest per bin face and suit a store with a spare wall. Free-standing double-sided louvre stands suit an island layout in the middle of a tool room and give you two faces for one footprint. Trolley-mounted panels, covered in the next section, put the faces where the work is. Shreeram Metafusion stocks louvre panels, stands, rails, universal rail, partitions and trolleys as accessories alongside the bin ranges, so the panel and the bins can be specified together and the hook geometry checked once rather than argued about after delivery. The full accessory listing sits under /products/fpo-material-handling-bins-and-accessories.
A practical caution about mixing bin ranges on one panel. It is perfectly possible to hang Rhino, Supra and Hippo bins on the same louvre run, and plenty of stores do exactly that because the ranges suit different parts. But it makes the wall visually noisy, and visual noise slows retrieval. If you are going to mix, mix by row rather than at random: one range per horizontal band, so that the eye can scan a row and know what it is looking at. And keep the label format identical across all ranges so that the reading pattern never changes even when the bin shape does. If you want to compare the ranges before committing, the side-by-side notes at /blog/supra-hippo-bull-rhino-bin-comparison are the fastest way to do it.
Trolley Combinations and the Mobile Maintenance Store
The strongest argument for the ARTB range is the case where the store goes to the machine rather than the other way round. A breakdown on a press line does not wait while a fitter walks 60 metres to the crib and back three times because he took the wrong size of dowel. A trolley carrying a louvre panel loaded with Rhino bins turns a series of walks into one walk. That is the use case the reinforced construction is really built for, because a trolley-mounted bin gets far more vibration, more knocks against door frames, and more sudden stops than a bin that lives on a wall.
Building a maintenance trolley is a small design exercise worth doing properly. Decide the job scope first: a trolley for a specific machine family carries a different bin set from a general electrical trolley or a general mechanical one. List the parts consumed on the last fifty jobs of that type — the maintenance log will tell you, and if it does not, that is a separate problem worth fixing. The parts that appear in more than a third of jobs go on the trolley. Everything else stays in the crib. A trolley that tries to carry the whole store carries too much weight, moves badly and still misses the part you need.
Loading discipline on a trolley is different from a wall. Heavy bins go low, because a top-heavy trolley on a shop floor with expansion joints and cable ramps will eventually tip, and it will tip on someone's foot. Bins that must not spill in transit — small loose items like grub screws — benefit from partitions to stop contents migrating from compartment to compartment when the trolley is pushed hard. Partitions are stocked as accessories for the bin ranges and they matter more on a mobile installation than a static one. Crash carts and universal rail are also part of the accessory family and are worth looking at when you are configuring a trolley from scratch.
Replenishment is the part that decides whether the trolley concept survives contact with reality. A trolley whose bins are empty is worse than no trolley, because the fitter now walks anyway and has lost confidence in the system. The two-bin approach handles this cleanly: each part on the trolley has an identical bin in the crib, and when the trolley bin empties, the fitter swaps rather than refills. The empty bin returns to the crib as the replenishment signal, which is visual, needs no paperwork, and works on a night shift when the stores counter is closed. Because ARTB bins of the same code stack and hang identically, the swap is genuinely a swap and not a fiddle.
The Maintenance Store and Tool Room Use Case in Detail
Maintenance stores have a storage problem that is structurally different from production stores, and it is worth naming because it explains most of the specification choices in this range. A production store holds a moderate number of part numbers in high quantity with predictable consumption. A maintenance store holds a very large number of part numbers in tiny quantity with unpredictable consumption. You might carry 1,200 line items of which 900 move less than twice a year, and the value of the store is not the stock, it is the certainty that the odd item is there and findable at 2 a.m.
That structure drives three specific requirements. Density of part numbers matters more than density of volume, which argues for many small bins rather than few large ones. Identification matters more than anything else, because nobody remembers 1,200 locations, which is why label holders are not an accessory here but a core feature. And durability matters disproportionately, because a maintenance bin might be touched only twenty times a year but it will be in service for a decade, and it will be handled by people wearing gloves in a hurry during a breakdown rather than by a trained picker working calmly.
The tool room adds a fourth requirement: the contents are heavy and often sharp-edged. Carbide inserts, HSS blanks, collets, boring bars, reamers and gauge pins are dense, and the smaller ones are exactly the things that get lost. A shallow ARTB bin at 95 x 89 x 43 mm internal is close to ideal for insert boxes and small tooling accessories: it holds a sensible quantity, it does not become a bottomless pit, and it stands up to being lifted full. For longer tooling, the answer is usually a different range or a drawer rather than a deeper bin, because a bin deep enough to stand a boring bar in is a bin that will tip forward.
There is a housekeeping benefit that maintenance managers consistently under-rate. A store where every part has a bin and every bin has a label makes stock-taking possible in an afternoon rather than a weekend, and it makes obsolescence visible. When a bin has been full and untouched for two years, you can see it, physically, from the aisle. The same information exists in the ERP and nobody looks at it. Visual stores management works because it puts the data where the decision is made. This is not an argument for bins over systems; it is an argument for bins as the physical layer of the system.
One last note on this use case. Maintenance stores in Indian plants are frequently in the least pleasant corner of the site: an unconditioned lean-to, a mezzanine over the workshop, or a room next to the compressor house. Ambient temperature swings widely, and the air carries whatever the plant makes. The -10C to +70C service range of the PP copolymer used across the Alkon ranges covers Indian ambient conditions comfortably in every state, including summer temperatures in Gujarat and Rajasthan interiors and winter conditions in the north, so the environment question is almost never about ambient air. It is about local heat sources, and the next section covers that.
Temperature, Chemicals and What the -10C to +70C Rating Actually Means
Every bin range from Alkon is moulded in polypropylene copolymer with resin code 05 and a stated service range of -10C to +70C, with food-safe and recyclable marks. Buyers read the temperature range and correctly conclude that Indian ambient conditions are not an issue. What catches people out is local heat, which is a completely different question. Ambient in a Chennai workshop in May might be 38C. The air 300 mm above a heat-treatment furnace door, next to an induction coil, or directly under an unshaded metal roof sheet at 3 p.m. can be far higher, and a bin does not care about the average conditions in the building. It cares about the conditions where it is.
The specific failure to watch for is creep rather than melting. Well before PP softens visibly, a sustained combination of load and elevated temperature causes slow permanent deformation. A stack of loaded bins parked against a warm wall will, over months, take a set: the rims lose their crispness, the columns stop locating cleanly, and the bins no longer sit square in a louvre panel. Nothing dramatic happens, which is why it is rarely diagnosed correctly. The fix is layout, not material: keep bins out of the direct radiant field of furnaces, ovens, curing chambers and unshaded roof sheets, and do not park loaded stacks against a wall that gets afternoon sun.
On chemistry, polypropylene is broadly indifferent to what a general engineering plant contains: cutting fluids and coolants, mineral oils, most aqueous cleaners, dilute acids and alkalis, and the salt-laden coastal air of Mumbai, Navi Mumbai, Chennai and Kolkata. The two categories worth checking before you commit are strong oxidising agents and certain aromatic or chlorinated solvents, which can cause swelling or stress cracking with prolonged contact. In practice this affects a small number of chemical, pharma and paint applications, not general engineering. If your parts arrive coated in something unusual, or if the bins will be wiped down with a solvent as part of the cleaning routine, confirm the specific chemical against the manufacturer's data before ordering rather than after.
Ultraviolet exposure is the last environmental factor and the one most often ignored, because the damage takes years and appears as brittleness rather than as visible change. Bins stored outdoors under a shed, or on a rack directly beneath a translucent roof panel, accumulate UV dose continuously. They will look fine and then crack at the rim on a routine knock. If part of your storage genuinely sits in daylight — a receiving area with a polycarbonate roof, an open-sided godown in a Gujarat industrial estate — treat those bins as a shorter-life population and plan to replace them rather than expecting the same service life as an indoor set. Reinforced construction gives you mechanical margin against handling; it does not give you margin against years of sunlight.
How Rhino Tuff Compares with Supra, Hippo and Bull Bins
Any honest guide to one range has to say when a different range is the better answer, and the Alkon catalogue is broad enough that the answer is often yes. Take the four small-bin ranges together. Supra Bins run SB 1 through SB 8 plus SB 7X, with SB 1 at 125 x 100 x 60 mm outside and 117 x 80 x 52 mm inside. Hippo Bins run 612/T, S, S2, M, DW and B, with 612/T at 100 x 110 x 53 mm outside and 80 x 90 x 43 mm inside. Bull Bins run from 5 to 55, with Bull Bin 5 at 168 x 102 x 74 mm outside and 145 x 86 x 66 mm inside. Rhino Tuff runs the ARTB series with ARTB-05 at 109 x 104 x 49 mm outside and 95 x 89 x 43 mm inside.
Compare the wall allowances and the picture becomes clear. Supra SB 1 gives up 8 mm across its length and 20 mm across its width to arrive at its internal cavity. Hippo 612/T gives up 20 mm and 20 mm. Bull Bin 5 gives up 23 mm and 16 mm. Rhino ARTB-05 gives up 14 mm and 15 mm. Each range makes a different trade between external footprint, usable cavity and structure, and none of them is objectively best — they are answers to different questions. Bull Bins are deeper and larger through the ladder, which suits bulkier items; Hippo bins are a compact, close-pitched format; Supra covers a wide ladder from small to large; Rhino Tuff is the reinforced, handling-focused option.
The selection logic that works in practice is to ask three questions in order. What does the bin weigh when full? How many times a day is it touched, and how roughly? Does it live in one place or move? Heavy plus rough plus mobile points at Rhino Tuff. Light plus frequent plus static points at Supra or Hippo, where the size ladder gives you more choice of footprint. Bulky plus static points at the larger Bull codes. Most plants end up using more than one range, and that is the correct outcome rather than a failure of standardisation, provided each range has a defined role that a new storesperson can be told in one sentence.
The detail pages for each range carry the full size ladders and are the right place to check before you finalise a schedule: the Supra range at /alkon-supra-bins-india, the Hippo range at /alkon-hippo-bins-india, and the Bull range at /alkon-bull-bins-india. For a direct side-by-side of construction and intended use, the comparison write-up at /blog/supra-hippo-bull-rhino-bin-comparison covers the same ground with all four ranges in one table, which is usually more efficient than reading four pages when you are deciding rather than ordering.
Where ARTB Fits Alongside Shelf Bins, Pick Bins, Tilt Bins and Organisers
Rhino Tuff bins are one solution to small-parts storage and the catalogue holds several others, each optimised around a different retrieval geometry. Panda Shelf Bins, running PSB 301 through 606 with transparent T versions, are long and shallow — PSB 301 measures 315 x 100 x 60 mm outside and 293 x 86 x 55 mm inside. That proportion is deliberate: a shelf bin is designed to be pulled forward out of a deep shelf like a drawer, so length is capacity and width is pitch. Where a Rhino bin gives you a face you reach into, a shelf bin gives you a tray you pull out. For a store with deep shelving already installed, shelf bins recover depth that open-front bins waste.
Koala Pick Bins, the AKP series, sit at the small and fast end. AKP-01 measures 130 x 105 x 60 mm outside and 105 x 90 x 55 mm inside, close in footprint to ARTB-05 but shaped and mounted around high-frequency picking with matching Koala shelving. Roo Tilt Bins (RTB, and RTBW wall units) take yet another approach: the bin pivots forward so the contents present themselves to the hand, which is excellent for very high pick rates and for parts that are awkward to scoop from a flat-bottomed bin. ACO Component Organisers go the other way entirely — the ACO 18 cabinet at 457(H) x 424(W) x 164(D) mm holds many small compartments in a closed housing, which suits a bench, a service van or a laboratory where dust exclusion and portability matter more than open access.
Reading this as a spectrum helps. At one end you have closed, compartmented, portable storage for very small quantities of many items — the organisers. At the other you have large open containers for bulk — Mammoth Bins at 820 x 315 x 300 mm outside and 740 x 250 x 290 mm inside, or Tote Bins such as AK-421 at 400 x 255 x 100 mm outside and 365 x 230 x 90 mm inside for moving batches between stations. Rhino Tuff sits in the middle-small band, optimised for durability under handling rather than for maximum pick speed or maximum capacity.
In a real tool room you will usually see three or four of these coexisting, and that is the right answer. Organisers on the bench for consumables the technician uses in his hand. Rhino bins on a louvre wall for the fastener and small-tooling library. Shelf bins in the deep racking behind for slower items. Tote bins for moving a job's worth of parts to the machine. Specifying the whole set at once, from one stockist, means the labelling scheme, the accessory hardware and the replacement supply all stay consistent. The full range listing sits at /products, with the sub-ranges under /products/panda-shelving-systems-and-accessories, /products/koala-pick-bins, /products/roo-tilt-bins and /products/components-organisers.
ESD Considerations in Electronics Maintenance Areas
A maintenance store that serves electronics — drives, PLC cards, servo amplifiers, sensor modules, spare boards — has a requirement that standard polypropylene bins do not meet. Standard PP is an insulator and will accumulate a static charge through ordinary handling: sliding a bin out of a louvre panel, tipping components from one container to another, or simply moving through dry air. That charge can discharge into a component and cause damage that is frequently latent rather than immediate. A board that was handled in a standard bin and fails three weeks later on the line is almost impossible to trace back to the store, which is why this problem is chronically under-reported.
The correct answer is to use ESD-safe or conductive products for anything that is or contains a static-sensitive device, and Alkon supplies a dedicated ESD/conductive line for exactly this. The decision rule is straightforward and worth writing into your stores procedure: if the item carries an ESD-sensitive marking, or if it is a populated printed circuit board, an IC, a MOSFET-based module, a drive card or a sensor with onboard electronics, it goes in an ESD-safe container and it is handled at an ESD-protected workstation. Everything else — the mechanical spares, the fasteners, the bearings, the seals — is fine in standard bins.
The trap is partial compliance, which is common and gives false confidence. A store that uses ESD-safe bins on the electronics shelf but standard bins on the trolley that carries spares to the machine has broken the protected path at exactly the point where the part is most handled. The protected path has to run from receipt to installation without a gap. If a card travels in a standard tote for the last fifty metres, the ESD bins upstream have bought you nothing. Audit the whole route, not the storage location.
Environmental context matters here too. Static problems are worse in dry air, which means the risk profile changes across the year and across the country: a Delhi NCR or Ahmedabad workshop in winter, or any air-conditioned room running low humidity, will generate charges far more readily than a humid coastal site in Chennai or Kolkata during monsoon. That variation is a reason to standardise on ESD-safe storage for sensitive items year-round rather than relying on ambient humidity to save you. The ESD-safe range is listed at /products/esd-safe-products, and Visipro rack protectors at /products/visipro address the separate but related problem of protecting the racking itself in traffic aisles.
Specifying and Ordering: A Practical Checklist
Getting a bin order right is mostly a matter of measuring things before you order rather than after. The commonest cause of a disappointing delivery is not a problem with the bins; it is a mismatch between the bins and the structure they were meant to go into, discovered on the day the cartons arrive. The following sequence takes an hour or two and removes almost all of that risk. It applies whether you are fitting out a new tool room in a Pune plant or replacing a worn-out set in an existing store in Nashik.
Start with the structure, not the bin. Measure the clear width of the louvre panel, rail or shelf you will use, the clear height between shelves, and the usable depth. Note whether the shelving is adjustable. Then measure the parts: not the nominal size but the actual envelope of the largest item you intend to store in each bin class, and estimate the weight of a sensible replenishment quantity. Two-thirds full is the target for a picking bin, because a bin filled to the rim spills when it is pulled and hides its own label position when stacked.
Then run the arithmetic on fit and count before you convert to part numbers. Divide the panel width by the bin outside width plus clearance and round down; that is your bins per row. Multiply by rows and by panels for the total. Add a spare allowance — ten per cent is typical for a maintenance store — because bins get damaged, get taken to a machine and not returned, and get needed for a part number that did not exist when you did the survey. Ordering the spares with the original consignment is far cheaper and faster than a separate small order eighteen months later.
Finally, place the order with the accessories in the same line. Bins, partitions, louvre panels or rails, stands, trolleys and any labels should all be on one purchase order, so that hook geometry and pitch are verified together and there is a single point of accountability. Shreeram Metafusion Engineers has been an authorised stockist of ALKON Plastics for over 30 years and holds the range across 476+ products, which is what makes it possible to confirm compatibility across bins and accessories in one conversation rather than three. The current catalogue is at /downloads, application notes by sector at /industries, and enquiries go to enquiry@shreeram-metafusion.com or 93266 29967 / 98201 01937, Monday to Saturday 10:00 to 19:00.
The checklist below is worth completing in writing rather than in your head, and worth keeping on file afterwards, because it becomes the specification document for every subsequent top-up order. Stores that keep this record can reorder in five minutes three years later; stores that do not end up re-measuring the whole wall each time, or worse, ordering by eye and receiving bins that are eight millimetres wider than the run allows. Attach the completed sheet to the original purchase order in your system so that whoever handles the next requisition inherits the reasoning and not just the part numbers.
- Clear width, height and depth of every panel, rail or shelf the bins will occupy, measured rather than assumed.
- Largest actual part envelope per bin class, and the weight of a full replenishment quantity.
- Bins per row calculated from outside width plus clearance, rounded down, and totalled by row and panel.
- Standardised on two or three ARTB codes rather than a bespoke size per part.
- Spare allowance of roughly ten per cent included on the same order.
- Accessories — partitions, louvre panels, rails or universal rail, stands, trolleys — specified on the same purchase order as the bins.
- Labels specified at the same time, with the print format, stock type and location-coding scheme agreed before the bins land.
- ESD-safe items identified separately and routed to the conductive range, with the protected path checked end to end.
Supply, Lead Time and Buying from a Stockist in Navi Mumbai
ALKON Plastics Pvt. Ltd. describes itself as the manufacturer of the largest range of material handling bins in India, and the breadth is genuinely the operational advantage: nine ranges, 476+ catalogue products, and a single accessory family that works across them. For a buyer, breadth from one source means the bins on the louvre wall, the totes moving between stations, the shelf bins in the racking and the ESD containers on the electronics shelf all come from one supply chain with one set of compatibility rules, which is worth more over five years than any single-item price advantage.
Shreeram Metafusion Engineers Pvt. Ltd. operates as authorised stockist from Shop-1, Gagangiri Chs, Sector 17, Vashi, Navi Mumbai, Maharashtra 400703. The location is practically relevant rather than incidental. Navi Mumbai sits alongside the MIDC belts of Thane–Belapur and Taloja, is a short run from the Pune corridor, and is well connected for despatch to the industrial clusters of Gujarat, the auto and textile machinery concentrations of Tamil Nadu around Chennai and Coimbatore, the engineering and electronics base in Karnataka around Bengaluru, and onward to Hyderabad, Delhi NCR and Kolkata. Storage bins are bulky relative to their value, so where they ship from genuinely affects both cost and lead time.
On lead time, the reasonable expectation to set internally is that standard bin codes in common sizes are the fastest-moving items and less common codes in the ladder are the ones to confirm before you commit a project date. This is another argument for standardising on two or three ARTB codes: a standardised set is more likely to be available and easier to top up. If a plant shutdown or a new line commissioning is driving the date, say so when you enquire, because that changes how the order is planned rather than how it is priced.
One procurement habit that consistently pays off: buy the replacement population with the original one. Bins are a consumable with a long life, not a capital item with a fixed life. Over ten years a maintenance store will lose and break a meaningful fraction of its bins, and the ones it loses are always the ones you now cannot match, because the layout was built around a specific outside width. Holding a small buffer of the standard codes on site — twenty or thirty bins in a carton on a top shelf — keeps the store looking and working as designed instead of slowly filling with mismatched substitutes. Broader guidance on assembling a complete storage scheme, including racking and systems, sits at /warehouse-storage-bins-india and /products/storage-systems.
Maintenance, Cleaning and Getting a Decade of Service
Bins do not need much maintenance, which is precisely why what little they need is never done. A short routine folded into an existing housekeeping cycle keeps a set of ARTB bins serviceable and legible for many years. The single most valuable habit is to empty and wipe bins on a rotation rather than all at once — a section of the store per month, so that it never becomes a project that gets postponed. Warm water and a mild detergent are sufficient for polypropylene; solvents are unnecessary for ordinary oil and grime and introduce a chemical-compatibility question you do not need.
Inspect while you clean, because an empty bin shows you things a full one hides. Look at four places specifically: the stacking rim, for chips, crushing or loss of crispness; the front lip, for spread or cracking where it is grabbed; the base, for a set or sag that stops the bin sitting flat; and the label holder, for a legible, current label. A bin that fails on the rim should be demoted from stacking duty to a louvre panel where it carries no load above it, rather than being scrapped. A bin that fails on the base or the front lip should be replaced, because both faults will get worse and both make the bin harder to handle.
Labels deserve their own pass, and it should happen at the same time. Part numbers get superseded, descriptions drift out of step with what people actually call the item, and location codes change when a shelf is added. A label that says something the storesperson does not recognise is worse than no label at all, because it sends him confidently to the wrong bin. Reprint anything that is faded, oily, out of date, or written by hand. If your store has grown organically over years and the labelling is inconsistent, a single afternoon of reprinting the entire wall to one format usually pays for itself within weeks.
Contamination management is the last item and the most operationally important in a tool room. Mixed contents in a fastener bin are a slow-motion failure: one M6 bolt in the M5 bin, then two, then nobody trusts the bin. Prevention is a rule that nothing goes back into a bin without being verified, and a returns tray at the counter where anything unidentified is set aside for someone to sort rather than guessed into place. Partitions help where a single bin genuinely holds two related items, but the better answer is nearly always a second bin. It costs a few hundred rupees and it removes an error mode permanently.
Finally, treat the bin population as data. Once a year, count what you have by code, note what has been replaced and why, and compare it against your original schedule. A store that is quietly losing twenty bins a year has a process problem — parts going to machines and not coming back, or a trolley that never gets returned — and the bin count is the cheapest sensor you will ever install for detecting it. Where the count says the layout has outgrown itself, that is the moment to revisit the panel plan with the stockist rather than adding another mismatched shelf. Details on the full accessory and systems range are at /products/fpo-material-handling-bins-and-accessories, and enquiries via /contact or the Vashi office.
Frequently asked questions
What does ARTB stand for and how do I read Rhino Tuff bin part numbers?
ARTB is the part-code prefix used across the Alkon Rhino Tuff range, and every code in the series follows the same format: ARTB followed by a number that identifies the shell size. ARTB-05, for example, is the compact size measuring 109 x 104 x 49 mm outside with an internal cavity of 95 x 89 x 43 mm. When you raise a purchase order or a stores requisition, quote the full code including the numeric suffix, because the prefix alone identifies only the range and not the size. If you are matching bins to an existing installation, the safest approach is to measure the outside dimensions of a bin already on your louvre panel and confirm the code against the current catalogue at /downloads or by calling the Vashi office, rather than ordering from a description like "the small Rhino bin", since size ladders are easy to misremember months after the original fit-out.
What are the Rhino Tuff bin sizes, and how do I choose the right one?
The ARTB series runs as a ladder of sizes, with ARTB-05 as the documented anchor point at 109 x 104 x 49 mm outside and 95 x 89 x 43 mm inside. Rather than picking the size that holds the most, choose on two criteria: visibility and pitch. Visibility means that for a fast-moving picking face you want a bin shallow enough that you can see the bottom without tipping it, because everything below your line of sight slows retrieval and hides stock-outs. Pitch means the outside width should divide neatly into the clear width of the louvre panel, rail or shelf you already have, so that a run finishes flush instead of wasting eighty millimetres at the end. Work out bins per row by dividing the panel width by the bin outside width plus a few millimetres of glove clearance, then round down. Standardise on two or three codes across the plant rather than sizing each bin perfectly to its contents, because a standardised set stacks compatibly, transfers between departments and is far easier to replace.
How are Rhino bins different from Supra, Hippo and Bull Bins?
All four are open-front bins moulded in the same polypropylene copolymer, but they resolve the trade-off between external footprint, usable cavity and structure differently. Compare the anchor sizes: Supra SB 1 is 125 x 100 x 60 mm outside and 117 x 80 x 52 mm inside; Hippo 612/T is 100 x 110 x 53 mm outside and 80 x 90 x 43 mm inside; Bull Bin 5 is 168 x 102 x 74 mm outside and 145 x 86 x 66 mm inside; Rhino ARTB-05 is 109 x 104 x 49 mm outside and 95 x 89 x 43 mm inside. Rhino Tuff is the reinforced, handling-focused option, which is why it suits maintenance stores, tool cribs and trolley-mounted installations where bins are grabbed by the lip with a full load of dense metal parts. Supra offers the widest size ladder from SB 1 to SB 8 plus SB 7X; Hippo is a compact close-pitch format; Bull runs from 5 to 55 for bulkier items. Most plants end up using two ranges with clearly defined roles, and the side-by-side comparison at /blog/supra-hippo-bull-rhino-bin-comparison is the quickest way to decide.
How high can I safely stack ARTB bins?
There is no single number, because the limiting factor is the total weight bearing on the rim of the bottom bin rather than the count of bins in the column. Four bins of light electrical terminals may load a rim far less than two bins of stainless fasteners, so a rule expressed in bins is misleading. A practical field rule for a maintenance store is to keep a column low enough that one person standing flat-footed can lift the top bin off cleanly with one hand; if the top bin needs a stretch and a two-handed heave, the column is too high and it will eventually be pulled over. Two other rules matter more than height. Never stack different sizes, because a larger bin bridges across a smaller rim and puts the whole load on two edges instead of four, which is the loading case that cracks rims. And keep floor stacks lower than shelf stacks, since a floor stack has nothing beside it to prevent a sideways topple. Treat stacking as a reserve-stock technique, not a picking arrangement, since a bin in the middle of a column has its open face partly obstructed.
Can Rhino Tuff bins be used on a louvre panel and on a trolley?
Yes, and the combination is the main reason the range exists in its reinforced form. The bin hangs from a matching hook on the back onto the profiled slots of a louvre panel, so it can be relocated in seconds without tools, which lets the layout follow the work instead of being frozen at installation. The same panel can be wall-mounted, built into a free-standing double-sided stand for an island layout, or mounted on a trolley to make a mobile maintenance store. The trolley case is where the reinforced construction earns its keep, because trolley-mounted bins take vibration, knocks against door frames and sudden stops that a wall-mounted bin never sees. When configuring a trolley, load heavy bins low so the trolley does not become top-heavy on a floor with expansion joints and cable ramps, and use partitions to stop small loose items migrating between compartments in transit. Louvre panels, stands, rails, universal rail, partitions, trolleys and crash carts are all stocked as accessories alongside the bin ranges, so hook geometry can be verified on a single order.
What material are Alkon Rhino Tuff Bins made from, and what temperatures do they tolerate?
All the Alkon bin ranges, including ARTB, are moulded in polypropylene copolymer, marked with resin code 05, with a stated service range of -10C to +70C and food-safe and recyclable marks. Copolymer rather than homopolymer is the material choice that matters for a rough-handling range, because copolymer PP retains substantially more impact strength at lower temperatures and tolerates repeated flexing at the front lip without going brittle. That service range comfortably covers Indian ambient conditions in every state, so ambient air temperature is essentially never the constraint. The real risk is local heat: the radiant field near a furnace door, an induction coil, a curing oven or directly under an unshaded metal roof sheet in the afternoon. Sustained heat combined with load causes slow permanent deformation rather than melting, so rims lose their crispness and columns stop locating cleanly without anything dramatic ever happening. Keep loaded stacks out of radiant heat and away from walls that take strong afternoon sun, and the material limit will never be reached.
Are Rhino Tuff bins suitable for storing electronic spares and PCBs?
No, not for anything static-sensitive. Standard polypropylene is an insulator and will accumulate charge through ordinary handling — sliding a bin out of a louvre panel, tipping components between containers, or simply moving in dry air — and that charge can discharge into a component and cause damage that is often latent rather than immediate, showing up as a failure weeks later on the line and never traced back to the store. Anything carrying an ESD-sensitive marking, along with populated printed circuit boards, ICs, drive cards, servo amplifiers and sensors with onboard electronics, should go in the dedicated ESD/conductive product line rather than standard bins. The mechanical spares, fasteners, bearings and seals in the same store are perfectly fine in standard ARTB bins. The important discipline is to avoid partial compliance: if a card sits in an ESD-safe bin on the shelf but then travels to the machine in a standard tote, the protected path has been broken at exactly the point of most handling, and the ESD storage upstream has bought you nothing.
How do the label holders work, and what should go on the label?
Every ARTB bin has a moulded label-holder provision on the front face, which mechanically retains a printed label rather than relying on adhesive. That distinction matters in a tool room or machine shop, where oil mist will creep behind a stuck-on label over months and lift it, and where removing a residue-covered old sticker to change a part number is a nuisance. Put three things on every label as a minimum: the part number exactly as it appears in your ERP or stores register, a short description in the language your storespeople actually use, and the bin location code. Add a barcode or QR code at the outset if you have any prospect of scanning, since retrofitting scannable labels later means touching every bin in the store. Use printed labels rather than hand-written ones, and choose a synthetic or laminated stock rather than plain paper, because paper goes translucent and soft in an oily atmosphere. Adopt fixed-location coding so that the shelf position and the bin carry the same code and the register maps parts to codes; that way a rearrangement or a new storesperson does not erase institutional memory.
How should I clean and maintain ARTB bins, and when should a bin be replaced?
Warm water and a mild detergent are all polypropylene needs; solvents are unnecessary for ordinary oil and grime and only introduce a chemical-compatibility question. The habit that actually works is to rotate the cleaning — one section of the store per month — rather than treating it as an annual project that gets postponed indefinitely. Inspect while the bin is empty, because a full bin hides its own faults, and check four places specifically. The stacking rim, for chips, crushing or loss of crispness. The front lip, for spread or cracking where it is grabbed. The base, for a set or sag that stops the bin sitting flat on a shelf. And the label holder, for a legible and current label. A bin that has failed on the rim can be demoted from stacking duty to a louvre panel where nothing bears on it, rather than being scrapped outright. A bin that has failed on the base or the front lip should be replaced, because both faults worsen and both make the bin harder to handle safely when full.
