Fiberglass grating cover plate is also one of the types of fiberglass grating products. In short, the grating cover is based on the grating plus a layer of fiberglass raw material cover, thereby increasing its strength and weighting ability. The main difference between fiberglass grille covers and fiberglass grilles lies in their appearance. The appearance of the grille is a hollow and breathable grid style, while the cover plate is a closed type, with the addition of a cover plate on the grille.
