The fiberglass cable tray is a composite structural member with glass fiber as the reinforcing material and epoxy resin or polyester resin as the matrix, continuously formed through the pultrusion process. 1, making it ideal for caustic, harsh and marine environments. Eaton's B-Line series Marine Rung allows stainless steel banding of cables for coast guard requirements. It is manufactured from fiber reinforced polyester or vinyl ester resin so it has high corrosion resistance, long. Our Fiberglass Cable Tray gives you the load capacity of steel, plus the inherent characteristics afforded by Pultrusion Technology: non-conductive, non-magnetic, and corrosion-resistant. These characteristics reduce shock hazard and make our FRP cable tray transparent to radio waves, radar and. GRP cable trays are an effective alternative to more conductive steel or other metallic materials for containing and protecting cables. GRP trays offer low installation costs, and non-conductive and lightweight properties, making fibreglass cable trays the most effective solution available for a. The FRP Cable Tray is a cable support system made of Fiberglass Reinforced Plastic (FRP for short). Made from the highest quality pultruded materials, our Fiber Reinforced Polymer (FRP) cable tray is extremely durable and resistant to chemical attack, with a proven record of.
