The Powder coated cable tray is mainly based on the characteristics of the fire-resistant coating. Under normal temperature, the coating formed by the fire-resistant coating plays a protective and decorative role on the cable tray. When encountering high-temperature fire, the fire-resistant coating will undergo physical and chemical changes such as expansion and carbonization, forming a thick heat-insulating layer. This heat-insulating layer can effectively block the transfer of heat to the cable tray and cables, slow down the heating rate of the cable tray and cables, reduce the risk of cable damage or combustion due to high temperature, and thus extend the normal working time of the cables during a fire.

Cable Tray Substrate Materials: Generally, metal materials such as carbon steel and stainless steel are used. The carbon steel cable tray has high strength and good economy, which makes it suitable for fire-proof requirements in general environments; the stainless steel cable tray has better corrosion resistance and is suitable for harsh environments such as humid environments and those with corrosive media.

Fire-Resistant Coatings: There are two main categories: organic fire-resistant coatings and inorganic fire-resistant coatings. Organic fire-resistant coatings have good adhesion and decorative properties and also have excellent fire-proof performance, but they may release certain harmful gases at high temperatures. Inorganic fire-resistant coatings use inorganic substances as the main film-forming materials and have the advantages of non-flammability, non-toxicity, and smokelessness, with good fire-proof and heat-insulating performance and strong durability.

Powder-coated materials can be provided in different colors, such as Grey, Silver, Black, and Yellow, offering aesthetic appeal.
