TC Bins vs Standard Storage Bins: What’s the Difference?

Your Guide to Choosing the Right Small Parts Storage

Pick a part from the wrong bin often enough and your stock figures stop meaning anything. That is really what the choice between a small parts bin and a general storage container comes down to: whether the bin helps your pickers get it right, at speed, every time.

Here is how Barton’s TC bins compare with standard storage containers, and how to work out which one your operation actually needs.

TC bins vs standard storage bins: side by side

What are TC bins?

TC bins are part of Barton Storage’s Topstore range of semi-open-fronted containers. They are moulded from tough polypropylene and designed specifically for picking small parts, rather than adapted from a general-purpose box.

Two features separate them from an ordinary container. The first is a reinforced base with a wide stacking rim and locator, so a stack stays put. The second is the semi-open front, which lets an operative reach in while the bin is still stacked. Each bin also has an index card slot, so you label it once and it stays labelled — no peeling stickers, no guessing.

The internal faces are smooth, which stops grease and swarf building up and makes them easy to clean. That matters more than it sounds for oily parts. Barton moulds the standard range from non-toxic polypropylene; if you need bins for a food preparation area specifically, ask about the white antibacterial version rather than assuming the standard bin will do.

Alongside the four standard colours, there are three specialist finishes: black recycled, moulded from 100% recycled polypropylene; white antibacterial, which uses a silver-ion additive for hygiene-sensitive areas; and black anti-static, for handling static-sensitive electronic components, specified against BS IEC 61340-5-1.

What sizes do TC bins come in?

Seven, running from the TC1 at 0.46 litres up to the TC7 at 31.4 litres:

One thing that trips people up: the maximum stack load is the load carried by the bottom bin, not the load per bin. Stack four TC6s and the combined contents of all four must stay under 60kg — so roughly 15kg in each. Stack two and each can hold 30kg.

What are standard storage bins?

“Standard storage bin” is a catch-all term covering heavy-duty metal pans, Euro containers, attached-lid totes and general-purpose plastic boxes. Most are solid-walled plastic, though metal versions are still common in workshops and foundries.

They are durable, and in the case of Euro containers they are dimensionally standardised, so they palletise neatly and move through automated handling without fuss. The trade-off is access: closed sides and lids mean anything at the bottom of the container is out of reach until you take it off the stack.

The key differences

Both types stack, and both nest when empty. So that is not the deciding factor, whatever the product pages tell you. Four things actually separate them.

Access while stacked

This is the real difference. The TC bin’s semi-open front means an operative can pick from a bin part-way up a stack without moving anything above it. A closed container has to come off the stack first. On a workstation doing three hundred picks a shift, that difference is the whole argument.

Published load limits

TC bins publish a maximum stack load for every size, from 12kg on a TC1 to 60kg on a TC6, dropping to 40kg when that TC6 is mounted on a louvred panel. Standard containers vary far more widely by manufacturer, and the rating is not always easy to find.

Colour coding and Kanban

Standard bulk totes usually come in one colour. TC bins come in four, which is what makes them practical for multi-bin Kanban systems.

In a two-bin Kanban system you hold the same part in two bins. Pickers work from the first; when it empties, it goes to the replenishment point and they start on the second. The empty bin is the reorder signal, so nobody has to count anything or run a stock check. Colour coding lets you run several of these side by side — one colour per line, or per supplier — without anyone having to read a label to know where a bin belongs.

What they are for

Standard bins are built for bulk storage and for moving goods. TC bins are built for high-frequency picking at a workstation or bin wall. They are not really competing products; they are doing different jobs.

Which should you choose?

Choose TC bins where you are picking small parts by hand, many times a day, and you want colour coding and labelling built into the bin rather than bolted on afterwards.

Choose Euro containers, attached-lid totes or metal pans where you are storing or moving bulk, where the contents need protecting from dust or damage, or where you need a sealed lid.

Most warehouses end up running both: TC bins on louvred panels and shelving at the pick face, standard containers holding bulk stock behind it.

Frequently asked questions

Do TC bins fit louvred panels and shelving?

Yes. The sturdy back lip is designed to hook onto Topstore louvred panels, and the bins also work in Topstore cabinets and on shelving. Note the reduced rating when panel-mounted: a TC6 drops from 60kg stacked to 40kg on a louvred panel.

Are TC bins recyclable?

Polypropylene is widely recyclable — it carries resin code 5 — but what your waste contractor will actually accept varies locally, so it is worth checking before you assume. Barton also produces a black TC range moulded from 100% recycled polypropylene, which is the better answer if recycled content is what you are after.

Can they be colour-coded to order?

Yes. Barton can produce containers in own-brand colours to match corporate branding or warehouse zoning.

Are TC bins suitable for food use?

The standard range is moulded from non-toxic polypropylene, but non-toxic and food-contact approved are not the same thing. If you are storing food, or working in a food preparation area, ask specifically about the white antibacterial range and request the documentation.
