Product Spotlight: HD Series FRP Grating

The HD series of fiberglass reinforced plastic (FRP) grating is design to solve one issue: vehicle traffic. Other forms of FRP grating, both molded and pultruded, are for foot traffic only. Customers frequently have the response of “well how much vehicle traffic can the other stuff take before it breaks?” The answer is it is untested. However, when it comes to FRP we are often not simply told what to quote, but to make a recommendation. And we do not recommend vehicle traffic on any FRP grating except for HD series grating.

The HD series, or “heavy duty”, is made up of thick, rectangular bearing bars and cross-rods. It is similar to the other pultruded FRP grating systems expect that it is only available in the large, thick rectangles 1″, “1.25”, 1.5″, 1.75″, 2″, 2.25″ and 2.5″ thick. This means that the product is not manufactured in an “I” or “T” shape unlike other pultruded FRP products. The grating brochure available off the Redwood Plastics website gives a full load table and specs for the HD-6000 grating. You can access the grating brochure here.
