Fiberglass reinforced plastic -FRP rain drain tree grating is a kind of unsaturated polycarbonate resin (including m-phenylene, o-phenylene, vinyl, phenol, bisphenol A, etc.) as the matrix, glass fiber roving (medium or non-magnetic) as the frame on the custom-made sizing tool through a special process to make a plate with a certain rate of opening.
Fiberglass reinforced plastic FRP rain drain tree grating is made by interlocking woven glass fibers and the resin is poured and pressed as a whole, and its structure is shown in the figure on the left.
1. The glass fiber interlaced weave and resin fully penetrated, so that the lattice shed Sung a large degree of corrosion resistance.
2. The overall structure of the grating distributes the load evenly, which helps the installation of the grating and its installation support structure to bear the force evenly.
3. The glossy surface of the grating and the inclined body tip surface make the grating self-cleaning.
