        Cable Tray

        Cable trays are mechanical support systems that provide a rigid structural system for electrical cables, raceways, and insulated conductors used for electric power distribution, control, signal instrumentation, and communication. Metal cable trays are made of galvanized steel, stainless steel, and aluminum. Non-metallic cable trays are made of glass-fiber reinforced plastic.

        Specific types include:

        • Metal channel-type
        • Metal single rail
        • Metal and nonmetallic ladder-type
        • Metal and nonmetallic trough-type
        • Metal wire mesh/basket
        • Other cable tray systems

        Cable trays are essential to a building's electrical system, supporting cables in the same way that roadway bridges support traffic. They provide versatility and offer savings of up to 84 percent in labor costs.
