Our molded fiberglass grating using an open mold process, providing bi-directional strength and durability - Delivering years of reliable performance. Our FRP pultruded grating is produced by dipping fiberglass such as strand, mat and veil in a liquid resin bath and then pulling this combination through a heated die which shapes and cures the composite before it comes out the other end. Both FRP gratings are corrosion resistant, lightweight and non-conductive, making it a great option in commercial buildings for platforms, drain covers, floor grating, stair treads and walkways.
