As the name implies, the GFRP grille cover is a kind of sewage cover made of GFRP. From the comprehensive consideration, the glass reinforced plastics (GFRP) grid cover plate occupies a high position with absolute advantage. Although it is not as strong as some metal bilge grid plates, its corrosion resistance is far superior to that of metal grid plates. In terms of carrying capacity, it is far superior to the wooden and plastic sewage grid cover plate, and its design and safety performance is far superior to those above.
In various occasions, the types of cover plate used are mainly five types: GFRP grille cover plate, metal grille cover plate, wood grille cover plate, plastic grille cover plate and stone grille cover plate. Of course, the performance and application place of these five different materials are different.
