Due to the different environments in which Cable Trays are used, cable tray manufacturers have different requirements for materials to ensure their service life. If steel or aluminum alloy cable trays are used in places with certain corrosiveness such as chemical plants and sewage treatment plants, they will corrode and rust over time, severely reducing their service life.  

Fiberglass cable tray has the characteristics of high flame retardancy, heavy anti-corrosion, and high strength. It is more corrosion-resistant, insulated, has a long service life, convenient equipment, maintenance free, and can be designed with a length that is more convenient than any other type of Steel cable tray. However, due to the fact that fiberglass cable trays are made of composite materials, they are prone to deformation and aging when placed outdoors for a long time and exposed to high heat. So one ship is used for indoor places where the ambient humidity is not greater than 90 and the ambient temperature is -50~60 ℃. Steel or aluminum alloy cable trays should be used in dry indoor environments without corrosion resistance requirements. Aluminum alloy cable trays should be selected for those with electromagnetic interference resistance, especially for those with shielding requirements.   

Cable trays can be divided into ladder type, tray type, trough type, and assembled type according to structural methods, and can be classified into steel trays, aluminum alloy trays, stainless steel trays, fiberglass trays, etc. according to materials.

The selection of materials and structural methods for cable tray manufacturers should be confirmed based on the environment in which the cable tray is used, the nature and location of the laid cables. Even with good surface treatment, even a slight flaw formed during transportation, equipment, operation and maintenance can lead to the continuous expansion of corrosion. Therefore, Stainless steel cable trays are used in such places.
