1、 corrosion resistance：With excellent corrosion resistance to gas and liquid media of acids, alkalis, organic solvents, salts, and so on. The products have incomparable superiority in anti-corrosion fields. According to applying requirements, o-phenyl , iso-phenyl, ethylene type resins could be substrate materials. 2、 light weight and high strength：density of FRP gratings is not above 2，only 1/4 of that of steel，2/3 of that of aluminum. However, their strength is *0 times of that of hard PVC; and absolute strength exceeds that of aluminum and normal steel materials. 3、 flame retarding：flame transmitting rate of normal flame retardant grating （ASTM E**4） is not over *5；that of high grade flame retardant grating is not over *0. oxygen index is not lower than *8（GB ***4）. 4、 Aging resistance：using time is over *0 years. 5、 safe：the products have excellent electric insulation property, without breakdown at *0KV；no electromagnetic property, so they could be used in magnet sensitive devices; special structures of FRP grating endues the products with anti-gliding, anti-fatigue and other properties
