Properties of Powergrate FRP Molded Gratings: 1. Corrosion and chemical resistance Corrosion is a major problem for metal or wooden grating, stair treads and other products in many different industries such as chemical plants, food and beverage factories, water and wastewater facilities, power facilities. lanyu frp grating is particularly designed to provide safe, long-lasting, economical and worry-free solutions in environments where chemicals and other corrosive materials attack and destroy metal or wood. According to different environmental requirements, such resins as orthophthalic polyester, isophthalic polyester, vinyl ester or phenolic are chosen as matrix material. 2. High strength-to-weight ratio Lanyu manufactured as a composite of continuous fiberglass strands and high quality resin is integrally constructed for strength, but it is less than one-half the weight of steel grating allowing easy removal for access below floor level and installation with no heavy equipment and less manpower. Properly installed, lanyu gratings meet specified load requirements for steel and are more impact resistant than metal. 3. Impact resistance The impact resistance of lanyu grating allows repeated deflection without permanent d memory, so once the object is removed, the fiberglass grating will fully recover to its original position. 4. Fire retardant Fiberglass grating has flame spread rating of 25 or less depending on different resin systems as tested in term of ASTM E-84. Test Report can be offered upon request. Special fire retardant requirements can also be met by adding extra additives.
