Sell Double Color Composite Roofing Sheet

The product uses two or three-layer co-extrusion technology, a process completed, each layer materials have their own features, which surface materials for ultra-weather resin, to ensure product durability and resistance to chemical corrosion; Intermediate materials for just a good material toughness special to ensure the strength at the same time, increase the rigidity; The underlying material is white ductile material, in order to increase the plant a sense of space and light intensity. Three kinds of different materials to give the product their own features, and the organically combined to make a new generation of anti-corrosion compound APVC sheet of corrugated sheet to solve the product durability, corrosion resistance, small rigidity, a sense of space and aesthetic issues.
