Fiberglass Trench Covers
Fiberglass Trench Cover Grating
National Grating high-strength molded FRP grating can be designed and used like traditional trench cover grating, but with all the many benefits of fiberglass.
Pultruded FRP Trench Cover Grating
National Grating Fiberglass Trench Cover Grating is ideal for covering trenches, drains sumps, waterways, and many other flooring applications in corrosive environments.
FRP Trench Grating is the perfect long-lasting solution for covering open trenches and drains. Steel and aluminum grating have considerable down-sides; they corrode, wear down quickly, cause maintenance headaches and downtimes, and are costly to install.
Strong, Lightweight and Corrosion-Resistant
Pultruded Fiberglass Grating has the strength of steel, but it won’t corrode like steel can.
Safer Walking Surface for Trench Covers and Walkways
A coarse, gritted epoxy coating enhances traction.

Support and Stability
Pultruded FRP Trench Covers are equally strong in both directions
Easy Fabrication
FRP Flooring Panels are lightweight, easy to transport, and can be cut and fabricated using standard hand tools.
Extended Life
The coated resin surface increases resistance to chemical corrosion and continuous UV exposure.
MOLDED FIBERGLASS TRENCH COVER PANEL SIZES
Molded FRP Mesh is available in 1″, 1-1/2″ and 2″ thick Panels.
Standard Panel sizes are 3′ x 10′, 4′ x 8′, 4′ x 12′ and 5′ x 10′.
Molded Trench Grating with S.S. Clip
We can cut down the panels to any size you like, or you can cut them yourself. Be sure to use a diamond-tip blade as a standard saw blade will dull very quickly.
1-1/2″ x 1-1/2″ Square FRP grating is especially useful for replacing steel grating or aluminum grating in corrosive environments or where other types of gratings require frequent replacements. For smaller mesh sizes check out our mini-mesh Fiberglass Grating.
