Resin Glass Fiber Reinforced Plastic Grille Drainage Ditch Cover is a kind of plate-like material with many spaces made by special processing and compounding with glass fiber as the reinforcing material and unsaturated polyester resin as the matrix. Because it is compounded by resin and glass fiber, its density The smaller is not more than 2 kilograms per cubic decimeter, which is only 1/4 of steel and 2/3 of aluminum. Its strength is 10 times that of rigid PVC, and its absolute strength exceeds that of aluminum and ordinary steel. Its light weight can greatly reduce the foundation support, thereby reducing the material cost of the project. Resin Glass Fiber Reinforced Plastic Grille Drainage Ditch Cover is easy to cut and install, does not require hot fire and large lifting equipment, requires only a small amount of labor and electric tools, so that the installation cost is greatly reduced; it has excellent electrical insulation, flame retardant, aging resistance, corrosion resistance, and color can be selected at will. The color can be customized according to the customer's requirements, and the environment of the production site can be improved. Generally, the colors of FRP gratings are: yellow, black, gray, green, blue, red, and transparent or translucent. During use, one color can be used alone or in combination.
