FRP grid characteristics are as follows: 1, corrosion resistance: a very superior acid and alkali resistance, organic solvents and salts, and many other gas, corrosive liquid medium can, in the field of preservation has incomparable superiority. According to the actual use where required, can be economically choose to use O-type, isophthalic type, vinyl type resin matrix material. 2, light weight, high strength, and easy to cut and install. Because it is through the resin and glass fiber composite made of, its density is not less than 2, only 1/4 of the steel, aluminum 2/3. Its strength is 10 times rigid PVC, aluminum and absolute intensity exceeds the level of ordinary steel. Its light weight, can greatly reduce the base support, thereby reducing the material cost of the project. Its cutting installation simple, without flare and large lifting equipment, only a small amount of labor and power tools, making installation costs are greatly reduced. 3, anti-aging: life in 50 years. 4, flame retardant: common flame retardant grill flame spread rate (ASTM E-84) does not exceed 25; the flame propagation rate senior retardant vinyl grill does not exceed 10. Oxygen index of not less than 28 (GB 8924). 5, security: excellent electrical insulation, no breakdown voltage under 10KV; electromagnetic properties, are available on the magnetic sensitive equipment; special structure glass steel grille also has a non-slip, anti-fatigue properties. 6, inside and outside the uniform color, and color can be arbitrarily selected. Color can be customized according to customer requirements, improve the production workplace environment. 7, with better overall economic efficiency. 8, can be designed and strong, flexible dimensions, dimensional stability. The company can be customized according to customer requirements, such as the cells of different size, different dimensions, different load requirements. Greatest extent possible to meet customer requirements, and can minimize losses caused by the cutting, so as to save costs.
