Fiberglass profiles (GRP, or Glass Reinforced Plastic) are a corrosion free and cost effective alternative to concrete, wood, steel, and aluminum. Fiberglass is a strong and lightweight material made of plastic reinforced with thin glass fibers. This combination provides high strength, low weight, and excellent resistance to weather, chemicals, and corrosion.
