STEEL CABLE TRAY
Steel cable tray is used principally in environments which are relatively free from corrosive attack. It is available with various types of corrosion-resistant finishes; usually hot-dip or mill
galvanized. The main advantage of utilizing steel in cable tray fabrication is the high strength to low cost ratio.
ALUMINUM ALLOY CABLE TRAY
Aluminum alloy cable tray has less weight that the contractor has to carry around a plant and can make a difference in the number of workers required for an installation. Aluminum alloy has superior corrosion resistance in many chemical environments compared to HDG, and is sometimes referred to as marine grade aluminum. Aluminum can be cut or scratched and still retain its corrosion resistance without the need of a protective coating. When aluminum alloy tray is used with stainless steel hardware, the system can perform continually, with little to no degradation over time.
FIBERGLASS REINFORCED PLASTIC (FRP) CABLE TRAY
FRP cable tray is formed through fiberglass pultrusion and continuous mechanized production process. Based on its good corrosion-resistant and fire-retardant properties, FRP cable trays are mainly used to support insulated electric cables for power distribution in chemical industries, communications industries, oil and gas industries, metallurgy industries, etc.
