30 mm Textured Plywood Floor: A Thickness Guide
Contents
Floorboard thickness is chosen from the point loads and the support spacing, not by habit. A 30 mm textured plywood floor suits heavy-duty trailers and forklift traffic, while lighter duty can use thinner boards. The goal is the thinnest board that safely carries the real loads, to protect payload.
Why thickness matters
Thickness is where many floor specifications go wrong, set by habit rather than by the loads the floor will actually carry. Getting it right is both a safety and an economy decision. The full material calculation is in our material calculation guide.
Floorboard thickness is one of the most important specification choices: too thin and the floor flexes or fails, too thick and it wastes weight and money. Getting it right means matching thickness to the real loads.
This guide explains how, and when 30 mm is the right choice. For the recommended board, see our wiremesh plywood for vehicle floors guide.
Thickness should follow the loads and span, never habit or guesswork.
Point loads decide thickness
Because a single forklift wheel concentrates far more force on the board than a spread load, it is the point load that sets the requirement. Designing to that worst case is what keeps the floor sound under real, daily use. Panel standards are published by engineered-wood associations.
The decisive factor is the concentrated point load, such as a forklift wheel or pallet corner, not the average load. A floor must carry that worst case without crushing or deflecting.
Specifying from the heaviest realistic point load is what keeps the floor safe under daily use.
Support spacing and span
It is worth confirming the actual cross-member spacing on the vehicle rather than assuming a standard, since it directly affects the thickness needed. A quick measurement here prevents both a sagging floor and an over-built one.
Support spacing works hand in hand with thickness, since a board that is comfortable over close supports may sag over a wider span. Considering the two together gives the most efficient floor for the duty.
Thickness also depends on the spacing between supports. Closely spaced cross-members let a thinner board carry more, while a wider span needs a thicker board to avoid sagging.
Considering thickness and support spacing together gives the most efficient floor.
When 30 mm is right
Beyond carrying load, a 30 mm board also feels solid underfoot and resists the flex that makes a floor feel cheap, which matters on a vehicle worked every day. For heavy duty, that solidity is part of the value.
For forklift-rated trailers and container floors, 30 mm provides the depth to carry high point loads without excessive deflection. It is a sensible default where the duty is genuinely heavy.
A 30 mm textured plywood floor suits heavy-duty trailers, container floors and beds that see forklift traffic and heavy pallets. The extra thickness carries the high point loads these applications generate.
For demanding, forklift-rated duty, 30 mm is a common and sensible choice.
When thinner works
A practical approach is to identify the heaviest item the floor will ever carry and specify for that, then check the weight saving a thinner board would give. That comparison usually makes the right choice obvious.
Where cargo is hand-loaded or light, a thinner board saves both weight and cost while still carrying the real loads safely. The discipline is to confirm it handles the worst case, not to assume thinner is always fine.
Lighter trailers and bodies that carry hand-loaded or lighter cargo can use a thinner board, saving weight and cost. The key is that the thinner board must still carry the real point loads safely.
Thickness and payload
Over a year of trips, the payload reclaimed by not over-thickening a floor adds up to real capacity or fuel savings. Seen that way, choosing the right thickness is as much a commercial decision as a structural one.
On a commercial vehicle, every extra millimetre of unnecessary thickness is payload sacrificed on every trip. This is why over-specifying “to be safe” has a real, recurring cost rather than being a harmless margin.
A thicker floor weighs more, and on a commercial vehicle every kilogram of floor is a kilogram less of payload. This is why over-specifying thickness has a real, ongoing cost.
Balancing strength against weight is the heart of choosing thickness. Payload trade-offs are in our lightest durable floor guide.
Common mistakes
Most thickness errors come from defaulting to a familiar figure instead of working from the actual loads and span. A moment spent on the real worst case prevents both under- and over-specifying.
Avoid these
- Choosing thickness by habit instead of point loads
- Over-thickening and wasting payload
- Ignoring support spacing when setting thickness
- Under-specifying for forklift or heavy-pallet duty
Choosing the right thickness
In short, set thickness from the point load and span: 30 mm for heavy forklift duty, thinner where loads are lighter, always the thinnest that is safe. Tell us your loads and span and we will confirm the thickness. For the right board itself, see our wiremesh plywood for vehicle floors guide.
Choose thickness from the heaviest point load and the support spacing: 30 mm for heavy, forklift-rated duty, thinner where loads are lighter. Aim for the thinnest board that safely carries the load.
