The overall structure of the wind through the professional bodies of testing and destruction testing. Second, the use of the tarpaulin is a professional coating fabric PVC. Durable bonding performance: Knife coating technology Application of liquid PVC and fiber of physical and chemical bonding, coating directly on the fabric scrape on the fabric; solid welding performance: welded fabric can withstand a lot of tension, even in the Hurricane, frequent operation and other harsh environments, it will not affect the sealing degree of the weld; Durable service life: a certain thickness not only gives the knife-coated fabric good UV resistance, but also extended product life; Of the color fastness: As the pigment directly immersed in the PVC coating inside, so the blade coating fabric can maintain color is always bright as new. Anti-corrosion, mildew, UV and flame retardant (M2 and B1) and other properties of international standards, the use of properly preserved, the three to five years will not rot and mildew.
