Phenolic resin subway escape evacuation platform


Phenolic resin subway escape evacuation platform

1) products introduction

【leadfrp】Lidfrp composite metro evacuation platform based on phenolic resin as matrix material and glass fiber roving as reinforced material by specially pultrusion process, which has high strength, high density of flame retardant, low smoke, low toxicity, corrosion resistance, anti-aging, light weight, smooth surface, and low thermal conductivity, good insulation performance , uv resistance, impact resistance etc.Also,It can be easy installation, short construction period and it has free maintenance.Our phenolic resin evacuation platform products use of special technology in the process of production tooling, and get the national invention patent license.Patent No.Evacuation platform is mainly composed of composite panels, beams, oblique beam, armrest, special fittings.Panel through the brace and fixed in the tunnel wall, height and the floor flat, The passengers can step onto the escape way once the door is opened .
