PPGI PPGL ZINC COLOR ROOFING SHEET

PPGI and PPGL zinc color roofing sheets are produced by coating galvanized (PPGI) or galvalume (PPGL) steel sheets with a layer of paint. The base metal is protected by a zinc or aluminum-zinc alloy layer, which prevents corrosion. The paint layer adds an extra level of protection and enhances the aesthetic appeal of the roofing sheets. The production process involves cleaning the steel, applying a conversion coating, adding primer, and finishing with a topcoat of paint, followed by baking to ensure durability and adhesion.
