FRP IS UP TO 70% LIGHTER THAN STEEL WITH AN EXCEPTIONAL STRENGTH-TO-WEIGHT RATIO. Fibergrate FRP has a high strength-to-weight ratio when compared to traditional materials like metal, concrete and wood. FRP gratings can even be strong enough to carry vehicular loads while weighing less than steel gratings. A 38mm thick grating is the most common grating thickness as well as the industrial standard. With this type of grating, spans of up to 1100 mm with industrial load are easy to attain. This grating has a meniscus top surface, which results in good anti-slip properties.
