Fire-resistant coatings feature thin coatings, high耐火limits, and strong adhesion. Fire-resistant bridge supports have a sandblasted surface and are commonly used in fire protection equipment power distribution lines, including fire control rooms, fire pumps, fire elevators, smoke and exhaust fans, and automatic fire alarm systems. For power distribution lines other than the automatic fire alarm system, fire-resistant cables can be used instead of fire-resistant bridge supports. The bridge supports within buildings offer powerful functions, with fire-resistant bridge supports in underground parking garages requiring a耐火 duration of over 1 hour. These bridge supports are suitable for power cables below 10KV, as well as control cables, lighting wiring, and overhead cable conduits and tunnels for both indoor and outdoor applications. They are primarily composed of fire-resistant boards made from glass fiber reinforced materials and inorganic binders, combined with metal frames and other fire-resistant materials. Coated with fire-resistant paint, these bridge supports do not burn when exposed to fire, effectively blocking the spread of flames and offering excellent fire resistance. They are also resistant to oil, corrosion, and are non-toxic and environmentally friendly. Overall installation is convenient, the structure is reasonable, the service life is long, and they are aesthetically pleasing. Cables are installed in cable bridge supports, ensuring a clean environment and easy cleaning.
