Buy Pre Galvanized Powder Coating Cable Trunking With Split Plate - Black Coating Manufacturers, Supplier

The fire - resistant coating is closely combined with the cable trunking substrate, forming a uniform and firm coating on the surface of the cable trunking, which is not easy to fall off. Whether during the installation process or long - term use, it can maintain a good adhesion state, ensuring the stability of the fire - proof performance.

The cable trunking part of the fire - spraying cable trunking usually has various structural forms such as trough - type, ladder - type, and tray - type, which can be selected according to different usage scenarios and cable laying requirements. For example, the trough - type fire - spraying cable trunking has good sealing performance and is suitable for places with high requirements for cable protection and where dust and water vapor need to be prevented from entering; the ladder - type fire - spraying cable trunking has good air permeability, which is convenient for cable heat dissipation and is often used in places where there are a large number of cables and good heat - dissipation conditions are required.

After spraying the fire - resistant coating, the cable trunking still maintains high mechanical strength and can bear the weight of the cables and various external forces during the installation and use process. Different specifications and materials of the cable trunking substrate can be selected according to the actual bearing requirements to ensure safe and reliable use under various working conditions.

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

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.
