Composite Corrugated Tile Roofing Detailed Product Description ASA Composite Corrugated Tile Roofing -Providing 20-year Guarantee Using today's advanced twofold extrusion technology for one-off processing with a separate function in each layer: The surface material adopts the ASA high weather resistant engineering plastic . ASA is a ternary polymer made up of acrylonitrile, styrene and acrylate with outstanding durability, UV resistance and chemical corrosion resistance, which ensures the bright color and luster and superb durability and chemical corrosion resistance of the product; the sublayer material is the extremely tough polyvinyl chloride resin (PVC), which ensures strength while increasing rigidity. A. The surface material adopts the ASA high weather resistant engineering plastic. B. The sublayer material is the extremely tough and lightproof modified PVC. Featured by its lasting color (for 10 years), UV resistance (ensuring an extremely long service life), easy cleaning, light weight, water resistance, toughness, heat insulation, sound insulation, co rosion resistance, wind resistance, shock resistance, hail resistance, contamination resistance, environmentfriendliness, fire resistance, insulation and easy installation, ASA Spanish Style Tile Roofing provides advanced solutions for the workshops with corrosive substances and the areas with heavy acid rain as well as the durability of roofing. Application:Highgrade plants, steel factories, warehouses, farm market, market access, sheds and other highend roofing materials.
