Hot dip galvanized cable tray is a high-strength anti-corrosion wiring profile commonly used in industrial and outdoor electromechanical engineering. It is made of high-quality carbon steel substrate and processed as a whole through high-temperature hot-dip galvanizing technology. The coating has good permeability, strong adhesion, and excellent overall anti-corrosion and weather resistance, which is significantly better than ordinary electroplated galvanized cable tray. It is very suitable for use in high humidity, high corrosion and complex scenarios such as coastal environments, outdoor docks, chemical plants, municipal power, etc. The inside and outside of the bridge frame are galvanized without dead corners, which can effectively resist water vapor, salt, acidic and alkaline substances, and UV erosion. Long term use is not easy to rust and peel off, and the service life is longer, greatly reducing the frequency of maintenance and engineering costs in the later stage. The product has a stable structure and balanced load-bearing capacity, suitable for laying various types of power cables and control cables. Standard specifications, flexible installation, neat and standardized wiring, convenient for later line maintenance and upgrading, are the preferred profiles for outdoor anti-corrosion wiring.
