1680d Polyester Fabric is also called flex door fabric because it can be used as a flexible door. And this fabric has many advantages.
The flex door fabric are made of special PVC composite fabrics. The non-flammability is grade A. According to SIS650082, ASTM_E84-94 or relevant domestic standards, the color of the door curtain is guaranteed to remain unchanged for five years.
The flexible door has a large area (800-1500m2), strong wind resistance (12-level typhoon), good thermal insulation performance, strong sealing, stable and reliable, easy to operate and easy to maintain. A steel frame or an aluminum beam is connected between the two layers of cloth to the beam for the wind-resistant skeleton, and the bottom has a steel truss. By adjusting the thickness and spacing of the beam, it can basically resist any wind pressure, so the flexible lifting gate can be used in any area.
