Zinc Painted Surface Roofing Sheet Factory Colorful Metal Ppgi Corrugated Steel Plate
| Corrugated roof sheets (also known as roof cladding) has been installed on buildings for many years and, due to its very easy installation process and excellent protective qualities, it still proves incredibly popular today.we manufacture and supply full prime steel galvanised corrugated roof sheets to contractors, businesses and the domestic sector. The color-coated coil is a product made of galvanized sheet as the substrate, after surface pretreatment (chemical degreasing and chemical conversion treatment), one or several layers of organic coatings are applied on the surface, and then baked and cured. It is also named after the color steel coils coated with organic coatings of various colors, referred to as color coated coils |
