Molded Fiberglass Grating


UltraGrate Fiberglass Grating is a hand lay-up composite of resin and continuous glass fiber strand that is thoroughly wetted out and woven through an open mold.

This method ensures good strength and high corrosion resistance.

Our UltraGrate FRP Grating is an excellent alternative to metal grating where rust, corrosion, or chemical attack are problems. With proper resin selection, it is an economical option in a wide range of corrosive environments.


UltraGrate Fiberglass Grating is a candidate material where there are safety concerns due to the presence of liquids and oils on the floor as well as corrosive environments where chemical resistance of the flooring material is important for long term durability.
