1, corrosion resistance: a very excellent acid and alkali resistance to organic solvents and salts, and many other gas, corrosive liquid medium can, in the field of preservation has incomparable superiority. Based on actual use where required, can be economically choose orthophthalic, isophthalic type, vinyl type resin as matrix material. 2, light weight, high strength, and easy to cut and install. Because it is by the resin and glass fiber composite, having a density of not less than 2, only 1/4 of the steel, aluminum 2/3. Its strength is 10 times the rigid PVC, aluminum and absolute intensity level than ordinary steel. Its light weight, can greatly reduce the basic support, thereby reducing the material cost of the project. Its cut is easy to install, no flare and large lifting equipment, only a small number of manual and electric tools, making installation costs are greatly reduced. 3, anti-aging: life in more than 50 years. 4, fire-retardant: Normal flame grille flame propagation rate (ASTM E-84) does not exceed 25; flame propagation rate advanced retardant vinyl grid does not exceed 10. Oxygen index of not less than 28 (GB 8924). 5. Security: has excellent electrical insulation, no breakdown voltage under 10KV; no electromagnetic resistance, can be used on sensitive magnetic equipment; special structure FRP grid also has non-slip, anti-fatigue properties. 6, inside and outside the uniform color, and color can be arbitrarily chosen. 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 sizes, different dimensions, different load requirements. The greatest extent possible to meet customer requirements, and can minimize the loss caused by the cutting, so cost savings to customers.
