Due to their excellent corrosion resistance, PVC-coated steel roofing panels have become the material of choice for factory roofs in the chemical, coastal, and seafood processing industries, significantly extending service life and reducing maintenance costs. Their fluororesin coating remains stable in acidic, alkaline, and salt spray environments, showing no signs of rust or peeling even after ten years—outperforming color-coated steel roofing sheets. However, it is important to note that cut edges are prone to aging; they should be promptly coated with edge-sealing paint to prevent accidents.
PVC roofing tiles are a new type of roofing material primarily made of polymeric materials, widely used in corrosive environments such as industrial plants. They offer excellent corrosion resistance and can effectively withstand acid, alkali, and salt spray corrosion, outperforming ordinary metal roofing sheets. This is due to their polyvinyl chloride (PVC) substrate, special coating, and added stabilizers and anti-aging additives. Compared to resin roofing tiles, plastic-steel roofing tiles offer superior corrosion resistance, while PVC roofing tiles are more cost-effective....
