FRP Cable tray
FRP Cable Trays are robust, lightweight supports made from fiberglass reinforced plastic (FRP), designed to carry and protect electrical cables in industrial and commercial installations. They offer excellent resistance to corrosion, moisture, and chemicals, making them ideal for harsh environments where steel trays may fail. With non-conductive and fire-retardant properties, FRP cable trays provide safe, reliable, and long-lasting performance. Available in ladder, perforated, trough, and solid-bottom designs, they are suitable for power plants, refineries, marine applications, telecom, and infrastructure projects.
