Racking is bolted to a floor and made of coated steel, and both of those facts decide more than most operators expect. A slab determines what can be anchored into it; a coating determines how long the steel lasts in a cold store or three kilometres from the sea.
The slab sets the ceiling on everything above it. It decides what can be bolted down, how heavily a footplate can load a single point, whether a very narrow aisle truck can operate, and how much of your maintenance budget goes on joints.
It is also the one thing that is genuinely hard to change later. Racking can be moved — see relocating and reconfiguring racking — and trucks can be replaced. A floor is poured once.
Floor loading, anchor selection and section capacity are engineering questions with site-specific answers, and we do not publish figures for them. What these pages do is explain what the question is, what governs the answer, and who is qualified to give it.
One finding worth naming here because it surprised us: we went looking for an Australian Standard covering industrial floor flatness and levelness, the way the UK has one, and could not find one. Australian floor-survey firms test to imported specifications instead. That is set out in full on the flatness page rather than buried.
For how the floor constrains the layout above it, see warehouse layout and capacity planning.

Most warehouse floors are a slab-on-ground, poured once and rarely thought about again. Some are suspended, and a growing number are post-tensioned — and that last category changes something as basic as where you are allowed to drill.
The UK measures warehouse floor flatness against TR34. The US uses the FF/FL system. Australia has neither of its own, and the gap is wider than most operators realise — including the false but common claim that AS 1170 fills it.
Nearly every operational warehouse floor has chipped joint edges somewhere, and most people who walk past them daily could not name the defect or explain why it happens. It wrecks forklift tyres, shakes loads, and gets worse the longer it is ignored.
Cracking and curling are related but different problems, both driven mainly by moisture and temperature moving through the slab unevenly. This explains the mechanisms — it will not tell you whether a particular crack in your floor is cosmetic or structural, because that call belongs to whoever inspects it in person.
A slab can be entirely adequate for people and pallets walking and stacking across it, and still be the wrong slab for a racking upright standing on one small footplate. This page will not give you a number for either — that is the entire point of it.
Two anchor types do the same job in structurally different ways, and the wrong choice near a joint or slab edge is a real failure mode, not a technicality. This is what each type actually does, and why the choice belongs to an engineer rather than whoever is closest to the drill.
Epoxy, polyurethane and polyaspartic solve overlapping but different problems, and picking one on price alone tends to show up as a failure in exactly the environment where it matters most — a cold store is the clearest example.
Most floor damage does not mean the slab has failed — it means one of a small number of repair techniques applies, and the right one depends on whether the slab itself is still sound. This is what each option actually does, not a verdict on your particular floor.
Two racking sections that look similarly steel from across a warehouse can be made in genuinely different ways, and that difference changes how damage actually shows up — including damage you cannot see.
Both coatings protect steel. What actually separates them is what happens after the first knock — and that difference points toward a different coating in a dry shed, a cold store, a coastal site and a food-processing washdown area.
Corrosion risk is not the same everywhere, and Australia's own atmospheric corrosivity classification includes a category the base international system does not — a genuine, checkable reason to make a different coating decision depending on where the warehouse sits.
Pallet material is usually chosen on habit or whatever a supplier already has, when it is actually answering four separate questions: how heavy it is to handle, how hygienic it is, what it costs over its life, and how it behaves in a fire.
If you export on timber pallets, you have probably seen the small burned or printed mark on the block without knowing exactly what it means. This covers what is safely establishable about it — and where to confirm the rest directly, because the source pages for this topic were not fully reachable while researching it.
A pallet is the last piece of engineering between your stock and the beam it sits on, and a broken or badly positioned one quietly turns a beam designed for spread-out weight into something closer to a point load it was never designed to see.
