Buy Powder Coated Carbon Steel PG Pre Galvanized Cable Trunking Trough Type Channel - RAL5015 Blue 200*100 Supplier, Suppliers
Product Description
Product Overview
The Powder coated cable trunking, also called fire spraying cable trunking, features a layer of fire-resistant coating sprayed on the surface of a common cable trunking, endowing it with fire-proof and flame-retardant functions. When a fire breaks out, it can prevent the spread of fire for a certain period, protect the cable lines, ensure the normal operation of relevant electrical equipment during the fire, and gain valuable time for personnel evacuation, fire-fighting, and rescue operations.

Working Principle
The Powder coated cable trunking is mainly based on the characteristics of the fire-resistant coating. Under normal temperature, the coating formed by the fire-resistant layer plays a protective and decorative role on the cable trunking. 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 effectively blocks the transfer of heat to the trunking and cables, significantly slowing down the heating rate, mitigating the risk of structural damage or cable combustion, and extending electrical operation time during emergencies.
Structural Features
The fire-resistant coating is closely combined with the cable trunking substrate, forming a uniform, firm surface layer that resists detachment. It ensures long-term adhesion and reliable fire-proof performance throughout transportation, installation, and usage.
Available in multiple configurations including trough-type, ladder-type, and tray-type. Trough-type provides premium dust and moisture isolation; ladder-type facilitates high ventilation and rapid heat dissipation for high-density cabling.
Retains robust mechanical load-bearing capacity after coating application. Substrates and gauges can be specified precisely to withstand heavy cable weights and severe physical stresses under variable operating environments.
Materials
Constructed using high-grade metal profiles. Carbon steel provides heavy load performance and economic efficiency for general requirements; stainless steel delivers advanced anti-corrosion protection in humid and chemically active applications.
Utilizes organic coatings for enhanced surface aesthetics and flexible adhesion, or inorganic coatings composed of non-combustible formulations ensuring non-toxic, smoke-free insulation with superior thermal durability.
Powder-coated materials can be customized in a broad spectrum of colors from the standard RAL palette, including Grey, Silver, Black, and Yellow, delivering clean architectural integration.
