Several types of tray are used in different applications. A solid-bottom tray provides the maximum protection to cables, but requires cutting the tray or using fittings to enter or exit cables. A deep, solid enclosure for cables is called a cable channel or cable trough. A ventilated tray has openings in the bottom of the tray, allowing some air circulation around the cables, water drainage, and allowing some dust to fall through the tray. Small cables may exit the tray throug.
Cable tray pricing depends on materials, coatings, size, supplier margins, and order quantity —plus hidden costs like shipping and installation. The trays are available in a range of colors and styles, allowing them to blend in seamlessly with the building's design. When it is used outside, the red rust will tend to be visible after a period of 6 to 12 months. This is the bracket-to-bracket distance. Our range of products include hot dip galvanized cable trays, perforated cable trays, gi pct cable tray, stainless steel ladder cable tray, pre galvanized cable trays and powder coated perforated cable tray.
