Corrosion can not happen. Glass steel bridge use alkali glass fiber roving and its fabric as reinforcement material, welding or screwing connection, with the glass steel life for more than 50 years. Using unsaturated resin as matrix material, plastic colorant, glass steel bridge uses vinyl chloride (UPVC) resin as the main raw material. In fact, the material made for cable tray have something to do with the actual project. Glass steel belongs to high-quality composite materials, plus a proportion of the stabilizer, oil and other corrosive media, then it has antiseptic function and special filler. generally, plastic steel has 15-30years life. It is not very good for acid and salt, and it is not very ideal material for extrusion molding, corrosion protection and so on. Plastic tray has a price advantage, but the strength is not so good
. After adding other mineral filler, long life, and then cured by heating, extruding into various sections of the hollow section processing, steel is steel profiles and the main chemical composition is PVC.
