Zhongyi FRP Co., Ltd. Zaoqiang supply of Beijing FRP grating, FRP grating, Tianjin, Shanghai FRP grille cover. Zhongyi FRP grille www.frp1688.com Features: 1, corrosion-resistant: FRP molded grating acid, alkali, salts and many organic solvents and gas, liquid corrosion, corrosion in the field of incomparable superiority. It differs from traditional metal grille, the role of media in the chemical does not occur under the electrochemical corrosion and rust, will not make the structure of the material is damaged, do not require regular or irregular inspection, maintenance, it also Unlike wood and other materials will rot, mildew and other phenomena, is a traditional iron, wood, cement and other materials, upgrade products. Requirements based on actual usage situations can economically choose to use o-type, between the benzene type, such as vinyl-type resin as the matrix material. 
 2, high-strength lightweight: FRP molded grating is by resin and glass fiber composite, its density is small, compared with steel grating, fiberglass grating the density of steel is only 1 / 4, Al 2 / 3 , while the strength of rigid PVC 10 times more than the absolute strength of aluminum to achieve the level of ordinary steel. Its light weight, can greatly reduce the base support, to reduce the project cost of materials. The cutting and ease of installation, no need to flare and large lifting equipment, only a small amount of manual and electric tools, so installation costs are also greatly reduced. 
 3, flame retardant: FRP molded grating normal oxygen index (according to GB 8924 test) in 32 or more, the flame spread rate (according to ASTM E-84 test) as a flame retardant; high flame retardant vinyl grill transmission speeds of up to 10 below.
