The Fibergrate Fiberglass Molded Grating is a corrosion resistant, high strength to weight ratio 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 3/16" bearing bars at 1-3/16" centers. The panels measure 4' x 8' and are 1" thick with a load capacity of 100 psf. This grating is designed for use in corrosive environments and provides an alternative to traditional metallic gratings. The fiberglass material resists rust and chemical corrosion. Common applications include walkways, platforms, stair treads and more. Overall, this is a durable, lightweight FRP grating ideal for industrial use.
