The product is made from a variety of different kinds of polymers by physical blending and chemical grease bonding through innovative preparation process, which has two characteristics of steel and toughness Corrosion resistance This material overcomes the disadvantages of the original steel bridge, which is easy to rust and corrode. It is suitable for different climates and chemical corrosion.

The proportion of polymer bridge is one third of that of steel bridge. Compared with steel bridge, polymer bridge has certain advantages in transportation, loading and unloading It is made by innovative formula technology, all indexes meet the requirements of flame retardant materials, and the combustion performance reaches GB 8624 B1 grade products automatically extinguish after one second off fire Polymer bridge adopts double card slot connection, beautiful appearance and convenient installation However, the steel bridge frame needs to be welded and locked with a large number of screws to complete the connection, and there will be defects such as slag inclusion and burning through arc pits during welding The new generation of anticorrosion and anti-aging materials have the characteristics of strong oxidation resistance and weather resistance, and their service life is 5-10 times longer than that of conventional cable tray in general climate.
