This cable tray is made from carbon steel sheet, cold-formed into a ventilated tray design with uniform bottom perforations, and protected with a zinc coating (typically via pre-galvanizing or electro-galvanizing). It offers a balanced combination of mechanical strength, cost-effectiveness, moderate corrosion resistance, and enhanced cable ventilation. As an economical and widely available solution, it is extensively used for general-purpose cable support in commercial, industrial, and light utility applications where basic protection and heat dissipation are required.
