FRP bridge is composed of glass fibre reinforced plastic and flame retardant and other materials, pressed by composite moulding material with stainless steel shielding mesh.

Ordinary cable trays are divided into grooved cable trays, trunking cable trays and ladder trays, grid trays and other structures, by the bracket arm and installation accessories. Can be independently erected, can also be laid in a variety of buildings (structures) and pipe corridor support. Embodying simple structure, beautiful shape, flexible configuration and easy maintenance and other characteristics. If it is in the neighbourhood of the sea or belong to the corrosive zone, the material must have anti-corrosion, moisture resistance, good adhesion, high impact strength physical characteristics.

FRP cable tray is a new type of cable laying equipment, with the following advantages:

1. Lightweight and high strength: FRP cable tray is made of glass fibre reinforced plastic, which has the characteristics of lightweight and high strength. Compared with the traditional metal cable trays, FRP cable trays are lighter in weight, but higher in strength, able to withstand greater loads.

2. Corrosion resistance: FRP cable trays have excellent corrosion resistance and can be used in harsh environments for a long time. Not subject to acid, alkali, salt and other chemicals, will not rust and corrosion, and can maintain a good appearance and service life.

3. Good insulating property: FRP cable tray has good insulating property, which can effectively prevent the mutual interference between cables and the occurrence of short-circuit phenomenon. And the FRP material itself is also an insulating material, which can provide additional security.

4. Good flame retardant properties: FRP cable tray has good flame retardant properties, which can effectively prevent the occurrence and spread of fire. In the event of fire, FRP cable tray will not produce toxic gases and smoke, which can protect the lives of personnel.

5. Convenient installation: The installation of FRP cable tray is very convenient and fast, no need to carry out complex processes such as welding and cutting, just use bolts and nuts for connection. Also, FRP material has good plasticity, can be cut and processed according to the actual needs, to adapt to a variety of complex laying environment.

To sum up, FRP cable trays have the advantages of light weight and high strength, corrosion resistance, insulation, flame retardant, easy installation and economical and practical, which is an ideal cable laying equipment. It is widely used in electric power, communication, petrochemical and other industries.
