Floorboards for Open and Closed Truck Bodies
Contents
Both open (flatbed) and closed (box) truck bodies need textured wiremesh plywood floorboards, but open bodies face more direct weather, so a weatherproof glue class matters even more there. Grip, a sound core and thickness matched to loads apply to both. The right board keeps either body type safe and durable.
Open vs closed bodies
Specified correctly for its exposure, either body type gets a floor that stays sound and grippy for years rather than seasons.
It is easy to assume a closed body needs less of a floor than an open one, but the moisture simply arrives from different directions. Understanding how each body type is exposed leads to the right specification for both. Both build on the same core board, covered in our trailer floor selection guide.
Truck bodies come in open (flatbed) and closed (box) forms, and while both need a strong, grippy floor, their exposure differs. Understanding that difference helps you specify the right board for each.
In both cases, textured wiremesh plywood is the recommended floorboard. For the core case, see our wiremesh plywood for vehicle floors guide.
This guide compares the two body types and how to floor them.
Open (flatbed) bodies
Sun exposure adds a second stress on a flatbed floor, since repeated wetting and drying cycles are harder on a board than constant damp. A weatherproof board copes with this cycling far better than an interior-grade one.
On a flatbed, the floor is effectively an outdoor surface, soaked by rain and dried by sun in turn, which is punishing for any board. A weatherproof glue class is not a nicety here but the difference between a floor that lasts and one that fails in a season.
Open and flatbed bodies leave the floor fully exposed to rain, sun and road spray. The floor must therefore handle direct weather as well as loads, making a weatherproof glue class essential.
Grip matters here too, since loading often happens in the open in poor weather.
Closed (box) bodies
A box body shelters the floor from direct rain, yet washing out the load space, condensation overnight and damp or wet cargo all keep the floor exposed to moisture. Treating a box floor as “dry” is a common and costly misjudgement.
Closed box bodies shelter the floor from direct rain, but moisture still enters from washing, condensation and damp cargo. The floor is protected from the worst weather but is far from dry.
A weatherproof board remains the safe choice, since interior-grade panels still fail with the moisture a box body sees.
Exposure and moisture
Thinking in terms of moisture sources rather than just rain clarifies the decision: both body types meet water, just by different routes. Once that is clear, the weatherproof glue class becomes an obvious requirement for either.
The key difference is exposure: open bodies meet weather head-on, while closed bodies see moisture from other sources. Both demand a weatherproof glue class, but the case is even stronger for open bodies.
Grip in both cases
Because loading and unloading happen on the floor in all weathers, grip protects workers and cargo regardless of whether a roof is overhead. A box body in the rain still has a wet floor at its open doors during loading.
Both body types benefit from an anti-slip surface, since loading and unloading happen on the floor in all conditions. The textured wiremesh surface keeps traction whether the body is open to the rain or a damp box.
Grip protects workers and cargo regardless of the body type.
Glue class for each
The honest summary is that an open body makes the weatherproof case undeniable, while a closed body makes it strongly advisable. In neither case does an interior-grade board belong on a working vehicle.
For open bodies, a weatherproof (WBP) glue class is non-negotiable given the direct exposure. For closed bodies it is still strongly recommended, because washing and condensation create plenty of moisture.
Matching the glue class to the real exposure is the key decision for both.
Thickness and loads
On mixed fleets it is common to standardise on one board specification across vehicles to simplify stock and repairs, adjusting only the thickness where duty differs. That consistency is a quiet operational saving.
Matching thickness to each vehicle’s real duty avoids both an under-built floor that flexes and an over-built one that wastes payload. A heavy flatbed and a light box van are simply different load cases.
Thickness depends on the loads each body carries, especially point loads from forklifts and pallets. A heavy-duty flatbed and a lighter box van may need different thicknesses, set from their real loads.
Thickness selection is covered in our thickness guide. Panel standards are published by engineered-wood associations.
Choosing the right board
In short, both body types take the same textured wiremesh board; the open body simply makes the weatherproof glue class non-negotiable. Tell us your body type and loads and we will confirm the right floor.
For both open and closed bodies, specify textured wiremesh plywood with a weatherproof glue class and a thickness matched to the loads. Open bodies make the weatherproof requirement even more critical.

Frequently Asked Questions
Both need textured wiremesh plywood, but open bodies face direct weather, so a weatherproof glue class is even more critical there.
Yes. Even sheltered from rain, a box body sees moisture from washing, condensation and damp cargo, so a weatherproof board is recommended.
Yes. Loading and unloading happen on the floor in all conditions, so an anti-slip surface protects workers and cargo on both open and closed bodies.
