Pultruded fiberglass grating is made using premium grade isophthalic polyester, vinyl ester or phenolic resin systems with a synthetic surfacing veil, making it corrosion resistant, lightweight, and durable. Pultruded fiberglass has a grit surface for safety, and a greater strength to weight ration than molded fiberglass grating. A 35% / 65% resin to glass ratio provides greater strength and less corrosion resistance than molded fiberglass. This product is better suited for longer life spans.
