Building Material PPGI Color Coated Metal Roof Sheet Corrugate
Products Materials:
First layer:weather resistant resin is selected as the top layer material to block the solar ultraviolet radiation and reduce the coefficient of heat conductivity. It provides our UPVC roofing material with great durability and chemical corrosion resistance
Second layer:the middle layer is a special foam structure with heat and sound insulation performances.
Third layer:the bottom layer of our heat insulated UPVC roof sheet adopts modified PVC material to offer optimum strength and rigidity. |
