What Is ASA+PVC Corrugated Roof Tile Sheet ?

- Jul 18, 2019-


PVC (Polyvinyl chloride) roof tile is made of polyvinyl chloride resin (PVC) as the main raw material, supplemented by UV anti-ultraviolet agent and other chemical raw materials, through scientific ratio, with advanced technology.

ASA+PVC corrugated roof tile sheet, also known as plastic tile, is a replacement product of color steel tile. Multi-layer co-extrusion technology is adopted to cover the anti-aging ASA layer on the surface of the product, which improves the weather resistance and color persistence, and increases the wear-resisting layer on the bottom surface.

It has good fire prevention, anti corrosion, weather resistance, no asbestos, bright color, environmental protection and health. also ASA+PVC Corrugated Roof Sheet used in the roof and wall of large-span gantry structure workshop, which not only meets the anti-corrosion requirements of light steel structure workshop, but also saves steel and reduces the cost.

Why Avoid Metal Roof Tile Sheet In Chemically Aggressive And Corrosive Environments?


◇ Agricultural environments such as barns, pigpens, hen houses, dairies, and stables can present hygienic and cleaning challenges for any roofing or cladding material. Gases such as ammonia and hydrogen are common in livestock feeding or housing environments, and they are the source of quick and widespread rust and corrosion for metal roofs and partitions.

◇ This corrosion results in high maintenance and replacement costs. ASA+PVC corrugated roof tiles and roof sheets offer a corrosion-free and chemical-resistant alternative that provides farmers with years of low cost, low maintenance and greater hygiene.


◇ Industrial environments such as mining and chemical processing plants create dust and ash that, when combined with mist, rain, and perhaps even saltwater, coat the roofing with a layer that is highly corrosive to metals. But not in the case of ASA+PVC corrugated PVC sheets. These solutions are virtually maintenance free as they can endure a wide variety of gases and chemicals for the life of the panel—and under the harshest conditions.
