Composite Material Evacuation Platform

Name: Composite Material Evacuation Platform
Brand: Longhua Technology Group (Luoyang) Co., Ltd.

Evacuation platforms are constructed along the side of subway line, so that in case of fire, traffic breakdown and other emergencies, passengers can reach the refuge area or tunnel exit through the evacuation platform and wait for rescue. The composite evacuation platform, FRP, is made of phenolic resin as base material, continuous glass fiber as reinforcing material, with aluminum hydroxide powder molded by pultrusion process. Phenolic resin is flame-retardant and glass fiber is non-combustible, so FRP has excellent fire resistance and fireproof performance.
