This cable tray is manufactured from carbon steel sheet, cold-formed into a rigid, fully enclosed channel structure, and then protected with a zinc coating (typically through pre-galvanizing or electro-galvanizing). It provides good corrosion resistance, mechanical strength, and cost-effectiveness for general-purpose cable management. Widely used in commercial buildings, industrial plants, power distribution systems, and other indoor or mildly corrosive environments where reliable cable support and protection are required.
