FRP grid = glass, steel grille cover glass fiber reinforced plastic grille Features: http://www.frp1688.com corrosion resistance: very superior acid and alkali resistance, corrosion resistance to organic solvents and salts, and many other gas and liquid media performance has incomparable superiority in corrosion protection. Requirements based on actual use situations, may choose to use the o-phenylenediamine type phenylene vinyl-type resin as the matrix material. 
 Lightweight, high strength: FRP grid density not greater than 2, only 1/4 of steel, aluminum 2/3. Its intensity is 10 times the rigid PVC absolute intensity than the level of aluminum and steel. 
 Anti-aging: the useful life of more than 50 years. 
 Retardant: ordinary retardant grille flame propagation rate (ASTM E-84) does not over 25; advanced flame-retardant vinyl grill flame propagation rate does not exceed 10. Oxygen index of not less than 28 (GB 
 8924) 
 Security: has excellent electrical insulation without breakdown voltage 10KV; electromagnetic, can be used in magnetic-sensitive equipment; FRP grid structure also has non-slip, anti-fatigue characteristics.
