FRP cable bracket and metal stents compared with the following bit: 
 1; corrosion resistance excellent outdoor acid, alkali, salt, most of the organic matter, water and damp places the useful life of more than 50 years; metal materials, even if galvanized are unable to reach (except stainless steel). 
 2; smooth surface will not damage the cable. The metal material is easy to make because the galvanized surface is not flat cable is damaged. 
 3; no recycling value of material so there is no theft value so theft: metallic materials have a higher recovery value, so easily stolen. 
 4: Materials for insulation. 
 5: the cost is lower than the metal material.
