Glass fiber-reinforced polyester grating

GRP

Product information
Pultruded GRP gratings consist of pultruded bearing bars and crossbars. Glass content is approximately 68%. Pultruded GRP gratings provide higher stiffness than moulded GRP gratings, enabling longer spans or a reduced construction height. The special arrangement and joint between bearing bars and crossbars ensures permanent stability. Bearing bars are manufactured according to EN 13706 and are composed of longitudinal glass fiber rovings, cross‑reinforcing glass fiber mats and a surface veil. Pultruded GRP gratings are available with I‑bar or T‑bar cross sections and a range of surface finishes. Refer to the manufacturer's information for anti‑skid properties when selecting a surface finish.
