Core Product Advantages
Outstanding Flame Retardant Performance
This fire resistant mesh cable tray adopts a high-performance fire-retardant coating compounded with polymer synthetic resin, flame retardants, foaming agents, charring agents and high-temperature refractory materials. The coating is applied strictly in accordance with the thickness specifications of JB/T 10216, with a minimum thickness of 500μm on the mesh surface. When exposed to open flames or ambient temperatures above 175℃, the coating expands and foams rapidly to form a flexible, sponge-like charred insulation layer. This layer effectively isolates cables from direct flame contact and stops fire from spreading along cable routes.
Reliable Heat Insulation & Heat Transfer Suppression
Compared with ordinary cable trays, this fire-resistant mesh model effectively blocks heat conduction in the early stage of a fire. In standard 30-minute fire resistance tests, the internal temperature rise of the tray is controlled within 150℃, providing stable and reliable heat insulation protection for internal cables. In daily operation, its open grid structure ensures unobstructed air ventilation, effectively avoiding cable overheating and long-term thermal aging, and extending the service life of wiring systems.
Flexible On-Site Cutting and Bending Adaptability
Inheriting the excellent on-site processing performance of traditional mesh cable trays, this fire-resistant model can be cut and shaped freely on site with ordinary cutting pliers. It supports flexible layout of various complex cable routes, including horizontal bends, up and down slopes, T-junctions and branches, fully adapting to the diverse wiring needs of different building structures.
It supports multiple installation methods, including ceiling suspension, wall mounting, bracket support and raised floor installation, covering all conventional and special installation environments for engineering projects.
Typical Application Scenarios
1. Data Centers and High-Density Cabling Scenarios
Data centers have extremely strict requirements for cable heat dissipation and fire safety. This fire resistant mesh cable tray retains the open grid structure to ensure efficient heat dissipation for high-density wiring. Meanwhile, it forms a reliable fire isolation barrier during fires to prevent regional fire spread.
2. Railway Transit Tunnels and Station Halls
Subways, light rails and other underground transit spaces feature dense pedestrian flow and limited evacuation passages, which put forward ultra-high fire protection requirements for cable systems. In tunnel sections, fire resistant mesh cable trays are used with matched fire-retardant wrapping materials to achieve full-length all-round protection for cables. Field test data shows the smoke penetration rate is controlled within 15% during fires, fully meeting the GB 50157‑2013 industry standard.
In addition, the product satisfies the Grade 8 seismic resistance requirement specified in GB 50981, with a fire resistance limit of no less than 60 minutes. It ensures the stable power supply of emergency lighting, smoke exhaust equipment and communication systems, guaranteeing the basic operation of fire rescue and evacuation systems.
3. Vertical Weak-Current Shafts and Fire Escape Routes in High-Rise Buildings
In high-rise office buildings and commercial complexes, vertical weak-current shafts and fire escape passages are key areas prone to vertical fire spread. Installed in these core areas, the fire resistant mesh cable tray effectively blocks fire from spreading along cable routes and prevents cross-floor fire diffusion.
It can be installed in non-ceiling spaces, realizing concealed and standardized wiring while meeting building fire compartment isolation standards. For densely populated commercial buildings, the product reaches B1 fire resistance rating and provides over 30dB sound insulation performance, adapting to the comprehensive functional needs of high-rise buildings.
Conclusion
- The fire resistant mesh cable tray perfectly combines the ventilation, lightweight and easy-installation advantages of traditional mesh trays with advanced fire protection technology, creating a targeted, high-safety cable management solution for special scenarios.
- It not only delivers excellent heat dissipation, lightweight structure and convenient construction, but also builds a solid fire safety barrier for core cable circuits during fires, guaranteeing the continuous and stable operation of key electrical systems.
