Superfrp pultruded gratings are assembled of several pultruded frp profiles, the frp profiles are made from glass rovings, continuous strand mat and surface mat which are impregated with resin and heat-formed in molds by the pulling action od pultrubers. Their tensile strength is higner than that of common steels, while the resin-rich surface layer provides for good corrosion resistance. Therefor, these profiles prove to be a best alternative to steels, in corrision environment and have found wider application.
