Fireproof spray painted Cable Tray has a complete national standard standardization specification system and is a specialized wiring profile for fire engineering. The entire series strictly follows the building electrical construction specifications, with standardized dimensions, parameters, and fire protection levels. It is widely suitable for commercial buildings, industrial plants, municipal fire protection renovations, building weak current engineering and other scenarios, and can meet different cable laying capacities and construction installation needs.

The standard size specifications of the product are complete, covering the vast majority of engineering universal models on the market. The mainstream width includes conventional specifications such as 50mm, 80mm, 100mm, 150mm, 200mm, 300mm, 400mm, etc. The side height is matched with multiple standards of 50mm, 60mm, 80mm, 100mm, which can flexibly adapt to different laying scenarios such as a small number of weak current lines, dense mixed strong and weak current lines, and high-power power cables. The standard single section length is uniformly 2 meters and 3 meters, suitable for the installation spacing of conventional brackets, and has zero error in construction docking.

Divided into multiple standard versions according to the thickness of the board, suitable for different load-bearing and installation scenarios. Lightweight sheet specifications are lightweight and suitable for indoor ceiling embedding and concealed light load wiring; The standard thickness version of the national standard is a universal engineering version, with balanced load-bearing capacity and strong stability, suitable for most tooling fire wiring projects; The thickened national standard version has higher structural strength, excellent resistance to pressure and deformation, and is suitable for high-altitude laying, long-distance wiring, and heavy-duty cable laying scenarios.

The fireproof spraying process specifications are standardized and unified, using high-voltage electrostatic spraying technology. The fireproof powder coating has a uniform thickness and firm adhesion, and the overall flame retardant, thermal insulation, and fireproof performance are uniformly up to standard. The supporting accessories for all specifications of cable trays are completely universal, and various tees, bends, reducers, cover plates, and fixed hangers are produced according to standard sizes. They are matched with regular wiring and have good sealing properties. At the same time, they are compatible with conventional non-standard fine-tuning sizes and suitable for various standardized and special fire wiring projects.
