The polymer anticorrosive composite cable tray is a new generation of cable tray developed by our company based on the "Cable Tray Standard". The company adopts a new type of anti-corrosion material independently developed, aluminum alloy cable bridge, based on traditional bridge materials and technologies, and developed a series of cable bridges under specific process conditions. Its anti-corrosion performance, cable tray, mechanical properties, composite epoxy resin cable tray, anti-aging performance, etc. are greater than other cable tray products. Break through the traditional process of relying on glass fiber and fillers to change the performance of anti-corrosion materials. Through modification and polymer conversion, micro-molecular penetration and micro-foaming technology have super-qiang anti-corrosion performance. Realize automatic production. The second-generation product adopts the structure of steel lining in the middle, which strengthens the bearing capacity and anti-distortion ability of the bridge.
