Grating And Ladder

The composition of the product by weight is 70% fibreglass reinforcement and 305 thermosetting polyester resin. By volume, each constituent is present in about equal proportions. The configuration of the grating is as shown in the figure below. Bearing bars are pultruded sections of 25 mm depth width and 8 mm width.The pultruded section ensures efficient material distribution resulting in a high strength to weight ratio. Bearing bars have slip resistance grit bonded to their surface to ensure slip resistance. Transverse members are 8 mm diameter rods of the same composition as the bearing bars. They are passed through the bearing bars and securely boded to them with structural adhesive. FRP gratings are supplied prepigmented, in most colour of the purchaser's choice. Standard colour is GREY.
