Polycarbonate board building material
Polycarbonate board is made of resin, such as awning: In the section of bridge and tunnel connected to tunnel and tunnel, in order to ensure the smooth driving of traffic, the project team also optimized some of the original design schemes. The tunnel exit is 65 meters away from the tunnel entrance. In order to prevent sudden changes in light when vehicles enter and exit the tunnel and snow in winter from affecting driving safety, a sunshade is set above the bridge between the two tunnels. The awning bracket adopts I-shaped steel, which effectively reduces the dead load of the bridge; the shed body adopts a sky blue translucent sun board, which effectively reduces the brightness in the shed, and it is consistent with the light color of the outside; there are ventilation holes in the lower part of the shed to ensure The tunnel exchanges gas with the outside world. It is a high-tech, excellent comprehensive performance, energy-saving and environmentally-friendly plastic sheet. It is a plastic building material commonly used internationally. Its products involve greenhouses, industrial plants, advertising signs, carports, exhibition lighting, stadiums, machinery, and factories. , Agricultural greenhouses, flower greenhouses, stations and other public facilities, highway sound insulation, advertising and decoration fields.
