Dimensions
& pallets.
If base type matters for your line, say which one in the message field and we will match it across the whole order.
The 48 × 40 inch footprint essentially never varies. Height does, by up to an inch, and the pallet base is why. Steel bases add about 5.5 inches under the bottle, composite 5.0, all-plastic 4.5, and legacy timber 5.75. Tare moves 14 lb across the same range. If you run fixed-height equipment, specify the base type.
Four base types, properly compared
| Base type | Characteristics |
|---|---|
| Steel | Adds ≈5.5 in, 32 lb. Four-way fork entry, repairable, fully recyclable, best load distribution. Can rust at weld points if coating is breached. Our default on reconditioned stock. |
| Composite (steel + plastic deck) | Adds ≈5.0 in, 24 lb. No exposed timber, washable deck, good for food applications. Decks crack under point loads from pallet jacks. |
| All-plastic | Adds ≈4.5 in, 18 lb. Lightest tare, fully washable, no corrosion. Often two-way fork entry only — check before specifying a fleet. Lower load rating in cold temperatures. |
| Timber (legacy) | Adds ≈5.75 in, 24 lb. Absorbs product, harbours pests, needs ISPM 15 stamping for export, splinters. Routed out of food-grade stock automatically. |
Dimensional tolerance, stated honestly
Catalogue dimensions are nominal. Across a mixed used fleet you should expect:
- Footprint: 48 × 40 in, ±0.25 in. Effectively fixed.
- Height, 275 gal: 45.5 – 46.75 in depending on base and bottle mould.
- Height, 330 gal: 52.5 – 53.75 in.
- Tare, 275 gal: 118 – 132 lb.
- Discharge centreline height: 7 – 9.5 in above floor. This is the one that catches out anyone building a drain pan or a catch tray.
Design to the top of each range and nothing will surprise you. The weight and load page covers the mass side of the same question.
Why the footprint is the whole story
48 × 40 inches is the GMA pallet, the dominant pallet standard in North America. By adopting it the IBC inherits, free of charge: every pallet rack beam in the country, every forklift fork spacing, 26 floor positions in a 53-foot trailer, standard dock-leveller geometry, and the ability to go through a 48-inch doorway turned sideways.
It is also why oversize units are disproportionately awkward: the moment you leave 48 × 40, you leave all of that behind at once.
Fork entry: the detail people miss
Four-way entry means you can pick the unit from any side. Two-way means only from the 40-inch faces. In a tight aisle or a packed trailer, two-way entry turns a thirty-second pick into a five-minute shuffle. Steel and composite bases are normally four-way; all-plastic bases are frequently not. If you are specifying a fleet, this is worth more than the four pounds of tare you save.

Base swaps
We replace damaged bases during reconditioning. A reclaimed steel base is $28 plus labour and frequently promotes a unit from technical to Grade A.
ReconditioningDimension & pallet questions
Which pallet base is best?
Steel for durability and four-way fork entry; composite for food applications where you want no exposed timber and no rust; all-plastic for washdown environments and the lowest tare. Steel is the most repairable and the most recyclable, which is why it is what we prefer on reconditioned stock. If you have no specific requirement, take steel.
Why does my new tote not sit at the same height as my old ones?
Pallet construction. A steel base typically adds 5.5 inches under the bottle, a composite base 5.0, and some all-plastic bases 4.5. On a nominally 46-inch unit that is a full inch of spread. If you are running a line with fixed-height fill nozzles or a gantry, specify the base type and we will match it across the order.
Are wooden-pallet IBCs still around?
Yes, mostly on older units and some one-trip export containers. They are perfectly serviceable but the timber absorbs product, harbours pests, fails ISPM 15 heat-treatment requirements unless stamped, and splinters. We route them out of food-grade stock automatically and generally recover the timber rather than resell on it.
Can a pallet base be swapped?
Yes, and we do it routinely during reconditioning. Swapping a damaged wooden base for a reclaimed steel one is $28 plus labour, extends the unit's life by years, and is usually the difference between a technical-grade unit and a Grade A one.
Four base types, measured
| Base type | Height added | Weight | Fork entry | Washable | Recyclable | Food use | Failure mode |
|---|---|---|---|---|---|---|---|
| Steel | ≈5.5 in | 32 lb | Four-way | Yes | Fully | Yes | Rust at breached weld points |
| Composite — steel frame, plastic deck | ≈5.0 in | 24 lb | Four-way | Yes | Separable | Yes, preferred | Deck cracking under point loads |
| All-plastic | ≈4.5 in | 18 lb | Often two-way only | Yes | Fully | Yes | Lower load rating in cold; brittle fracture |
| Timber (legacy) | ≈5.75 in | 24 lb | Four-way | No | Ground for mulch and fuel | Routed out automatically | Absorbs product; splinters; pest harbourage |
Which to specify
- No specific requirement: steel. Most durable, most repairable, four-way entry, best load distribution, fully recyclable. Our default on reconditioned stock.
- Food or pharmaceutical: composite. No exposed timber, washable deck, no rust to contaminate. Watch for deck cracking from pallet-jack point loads.
- Washdown environments: all-plastic. No corrosion, fully washable, lowest tare. Check fork entry before specifying a fleet.
- Never specify: timber. It absorbs product, harbours pests, fails ISPM 15 heat-treatment requirements without a stamp, and splinters. We route it out of food-grade stock automatically and generally recover the timber rather than resell on it.
The inch that ruins a fixed-height installation
Catalogue dimensions are nominal. Across a mixed used fleet the real spread is:
| Measurement | Range | Design to |
|---|---|---|
| Footprint | 48 × 40 in ±0.25 | 48.5 × 40.5 in |
| Height, 275 gal | 45.5 – 46.75 in | 47 in |
| Height, 330 gal | 52.5 – 53.75 in | 54 in |
| Height on forks, 275 gal | +4 to 6 in | 53 in |
| Tare, 275 gal | 118 – 132 lb | 132 lb |
| Discharge centreline above floor | 7 – 9.5 in | 9.5 in |
| Fill cap outside diameter | 6 in nominal, two thread standards | Confirm the marking |
A full inch of height spread on a nominally 46-inch unit comes almost entirely from the base. If you are running a line with fixed-height fill nozzles, a pump-over gantry or a conveyor interface, specify the base type and we will match it across the whole order rather than sending a mixed pallet.
Base swaps as a grade lever
We replace damaged bases during reconditioning: a reclaimed steel base is $28 of material plus labour. It is frequently the single step that promotes a technical-grade unit to Grade A, because a cracked composite deck is a disqualifier on its own while everything else about the unit is sound.
This is also why we separate and bale pallet bases rather than throwing them in with the cage steel — once bases had their own bay, graders started walking over to it looking for replacements, and we discovered we had been scrapping good bases while separately struggling to find them.
Why 48 × 40 is the whole story
48 × 40 inches is the GMA pallet, the dominant pallet standard in North America. By adopting it, the IBC inherits a vast amount of existing infrastructure at no cost:
- Every pallet rack beam in the country, at standard beam spacing.
- Every forklift fork spacing, and standard 42-inch fork length.
- Twenty-six floor positions in a 53-foot trailer, with no wasted width.
- Standard dock-leveller and dock-plate geometry.
- Pallet jacks, on smooth level concrete.
- The ability to go through a 48-inch doorway turned sideways.
- Standard stretch-wrap and strapping equipment.
- Interlocking with other units for four-high empty stacking.
None of that was designed for intermediate bulk containers. It was designed for grocery pallets, and the IBC simply adopted the dimensions and took the benefit.
Detailed questions
Can a pallet base be swapped on a unit I already own?
Yes. A reclaimed steel base is $28 plus labour and takes about twenty minutes. It is worth doing on any unit with a cracked composite deck or a splintering timber base, because it restores stackability and frequently extends the unit's life by years.
Are wooden-pallet IBCs still around?
Yes, mostly on older units and some one-trip export containers. They are serviceable but the timber absorbs product, harbours pests, fails ISPM 15 without a stamp and splinters. We route them out of food-grade stock automatically, and if you have them we would rather swap the base than sell you the unit as-is.
Does the base affect how much weight the unit can carry?
The load rating of the assembly is set by the cage and the bottle, not the base — but a cracked or non-flat base concentrates the load onto two feet instead of four, which works the base-frame welds every time the liquid moves. A sound base is a structural requirement, not a cosmetic one.
Which base is best for a forklift-heavy operation?
Steel, four-way, every time. It takes fork-tip strikes without cracking, it is repairable, and four-way entry halves the number of repositioning moves in a tight aisle. All-plastic bases chip at the pocket edges under the same treatment.
Do you stock all four base types?
Steel and composite in depth, all-plastic intermittently, timber only in units we have not yet swapped. If base type matters, specify it and we will match across the order — it is a sorting job rather than a sourcing job on reasonable quantities.
What is the discharge centreline height and why does it matter?
Seven to nine and a half inches above the floor, varying with base type. It matters to anyone building a drain pan, a catch tray or a decanting station, because a container that will not fit under the valve is a daily irritation. Design to 9.5 inches of clearance and you will be fine with any base.
Can I use totes with mixed base types in one rack?
Yes for racking — the footprint is identical. Not ideal for stacking, because the top frames end up at slightly different heights and the interlock is less positive. Keep stacks to a single base type where you can.
Is there a lightweight base for weight-critical shipping?
All-plastic at 18 lb saves 14 lb against steel. On a filled 275 that is 0.6% of gross weight, which almost never changes how many units fit a legal load. The saving is real on empty return freight at high volume and negligible otherwise — and you give up four-way fork entry for it.
Matching an existing fleet?
Tell us the base type and we will match it unit for unit rather than sending you a mixed pallet.
