Fire-Resistant Cable Tray Price

After processing and forming, the cable tray has a uniform cross-sectional shape without defects such as bending, distortion, cracks, or irregular edge margins. Regardless of the type, all fire-resistant cable trays must comply with the national standards for cable trays.

Fire-resistant coating is a high-efficiency maintenance product for steel structures. It is formulated with polymer synthetic resin as the film-forming material, combined with flame retardants, foaming agents, carbonizing agents, and high-temperature refractory materials. Under high-temperature conditions, the coating undergoes continuous foaming and expansion to form a flexible sponge-like carbonized insulation layer. This prevents load-bearing steel structures from rapid softening, deformation, or sharp strength loss due to exposure to high-temperature flames. The coating of external wall fire-resistant paint shall be uniform, glossy, and free of obvious color differences.

Standards for Fire-Resistant Cable Trays

Fire-resistant cable trays must comply with national standards for fire-resistant cables. Key requirements include:

Fire-resistant coating thickness ≥ 1mm;

Fire resistance rating ≥ 30 minutes (basic performance standard for fire-resistant paint on fire-resistant cables).

The base material of fire-resistant cable trays is steel, with an outer layer of fire-resistant material.

Priority should be given to cable trays made of steel, non-combustible, or flame-retardant materials. Fire-resistant cable trays adopt a steel shell with double-layer fire-resistant covers and built-in inorganic fire-resistant troughs. The thermal insulation layer has a uniform thickness of 25mm. The double-layer covers enable ventilation and heat dissipation, while the internal surface is coated with fire-resistant paint. When exposed to fire, the paint expands. During a 60-minute fire resistance test, the cables remain undamaged, and the supporting structure maintains excellent structural stability.
