Spraying plastic powder on the cable tray is a surface treatment method.

Trough tray, also known as trough Cable Ladder Tray Manufacturers, is a kind of fully enclosed cable tray, which is suitable for laying computer cable, communication cable, thermocouple cable and other control cables of highly sensitive systems. It has a good effect on cable shielding interference and cable protection in heavy corrosion environment. 
The trough cable tray is a trough component made of the whole steel plate, which is conceptually different from the tray rack in the ratio of height to width, shallow and wide, and the depth and sealing of the trough cable tray. 
It is made of cold-rolled steel plate and the surface process is hot-dip galvanizing. the full name of the rigid structure system with tight support cable is composed of trough type, tray type or cascade straight line section, bend, tee, four-way assembly, supporting arm (arm bracket), hanger and so on. 
Grid bridge is suitable for power and communication cable wiring as an extension of traditional bridge. Aluminum alloy bridge has the characteristics of beautiful appearance, simple structure, unique style, large load capacity, light weight and so on. 
After anodizing on the surface of aluminum alloy Cable Ladder Tray Manufacturers, it is not only anti-corrosion, but also anti-electromagnetic interference, especially shielding interference, which can not be replaced by steel bridge. 
Aluminum alloy bridge is of great practical value in modern industry, modern national defense and modern high technology. 
Anti-corrosion, do not deform at 65 degrees Celsius; good thermal insulation, thermal conductivity 0.14kcl/mhr degrees Celsius); non-toxic, harmless, no asbestos carcinogenic microorganism pollution, in line with world health standards; no mosses, prevent microorganisms, strong wind resistance under construction (can withstand 120 miles per hour)
