The fiberglass cable tray adopts the more advanced fiberglass pultrusion process at home and abroad, and is mechanized and continuously produced. Therefore, it not only fully has the advantages of the bridge produced by the domestic counterparts, but also the product size is stable, and the length can be selected arbitrarily. It can exceed 8 meters and has higher strength, stiffness and corrosion resistance. The thickness of the anti-corrosion layer on the surface of traditional metal cable trays is small and is easily damaged during transportation and installation. There are also tiny holes on the surface. Corrosive gases can easily enter the structural layer through the holes and affect the anti-corrosion effect. Non-metallic cable trays have strong anti-corrosion properties. But the mechanical strength is not enough.
Fiberglass cable tray is made of untwisted glass fiber and composite fiber with resin that is resistant to various climates and corrosion. It is continuously formed by mechanization in a certain proportion and at a certain temperature according to different use occasions. , is not only more economical than hand lay-up molding but also has higher production efficiency, especially the size can be chosen at will, and the quality of the product can be more effectively guaranteed. Therefore, the application of pultruded glass cable trays to replace iron bridges is the future of civil exhibitions. Required
