Welded ladder cable trays are manufactured from high-strength mild steel or stainless steel, with rungs resistance-welded to the side rails at regular intervals to form a rigid, open-bottom ladder structure. The open design ensures maximum ventilation for cables, simplifies cable laying, and allows easy inspection without dismantling the tray. Ideal for carrying heavy power cables, control cables, and instrumentation cables in power plants, refineries, substations, and large commercial complexes.
