Colour Coated Roofing Sheets

Colour coated roofing sheets are metal roofing panels made from high-strength steel or metal alloys that are coated with protective and decorative paint layers. The base metal (often galvanized steel or aluminium-zinc alloy) is pre-treated and then provided with one or more layers of organic coatings — giving it excellent corrosion resistance, weather protection, and attractive finishes.
