What are the advantages of FRP grating?

Light-weight:  its specific gravity is about 1.8, its weight is only 1/4 of steel material, and 2/3 of aluminum material. High strength: its strength is tenfold of RPVC, the raw intensity is much more stronger than aluminum material. Corrosion resistance: polyester type is a kind of  non-metallic material, it is resistant to rust, not moldy, staleproof, and no need to be painted. It is able to bear many kinds of corrosion of air and liquid. It is service-free. Therefore, some…

FRP Grating

1.Selection of materials To produce a high quality FRP grating, we choose resin, fiberglass fiber and filler calcium powder as its material, and collocate the materials with the ratio of 1:1:1. high quality FRP grating also need a high quality resin, Unsaturated adjacent benzene resin 196 owns many advantages, such as colorless and transparent, low viscous, exothermic low, low shrink, quick-curing, high-speed compatibility, High gloss, and so on. The FRP grating produced by high quality resin has characteristics of flat…

Differences between FRP grating and common steel grating
