Fibreglass Panels for Truck & Van Bodies & Trailers

Although we don’t construct truck bodies, we do supply the components to make them e.g. walls, roofs, floor panels, doors and bulkheads; aluminium extrusion corner caps & interior light shells.

Many of our panels can be seen on the roads in the form of truck and van bodies, trailers and semi-trailers.

Fibreglass Panels for Repair Work & Non-Slip Surfacing

We can undertake fibreglass repairs on your damaged truck body, and will happily supply insurance quotes for this work. With our fibreglass manufacturing facilities and skilled staff we can repair your truck and/or trailer body, motorhome or caravan.

We also offer a service where we apply a non-slip surface to any truck or trailer floor using grit-impregnated coating for durability and grip.

Why Choose Our Flat Sandwich Fibreglass Panels?

Structural Superiority

Sandwich panel construction delivers exceptional strength while keeping weight to a minimum. Perfect for applications where performance and efficiency matter.

Weather Resistance

Fibreglass construction resists corrosion, UV degradation, and moisture damage – ensuring decades of reliable performance in any climate.

Thermal Excellence

Superior insulation properties make our panels ideal for temperature-controlled applications, reducing energy costs and improving performance.

Manufacturing Efficiency

Integrated features like window and door apertures are precisely cut during production, eliminating costly secondary operations and ensuring perfect fit.

Size Leadership

Few manufacturers can match our 19-metre capacity, giving you design freedom unavailable elsewhere.
