The Fibergrate Fiberglass Molded Grating is a high strength, corrosion resistant grating made of a fiberglass reinforced plastic (FRP) composite. It has a matte gray finish and features a square mesh pattern with 1-1/2" x 3/8" openings. The panels measure 4' x 8' and are 1" thick. They have a load capacity of 100 psf with a maximum deflection of 1/4" at full load. The gratings are designed for use in corrosive environments and provide an alternative to traditional metal gratings. They can be used for flooring, walkways, platforms, stair treads and more. The fiberglass material resists corrosion from saltwater, wastewater, oils, and acids.
