This cable tray is manufactured from carbon steel and formed into the classic open ladder design, featuring two side rails connected by regularly spaced transverse rungs. It is protected by a zinc coating, typically applied via pre-galvanizing or electro-galvanizing processes. As the most common and economical type of ladder tray, it offers a reliable combination of good mechanical strength, moderate corrosion resistance, and excellent ventilation. It is widely used for supporting power and control cables across a broad range of general industrial, commercial, and utility applications.
