PPGI and PPGL coils are produced by applying a layer of paint to galvanized (PPGI) or galvalume (PPGL) steel coils. The base metal is coated with a layer of zinc (galvanized) or a mixture of zinc and aluminum (galvalume) to provide corrosion resistance. The paint layer adds further protection and enhances the aesthetic appearance. The painting process involves cleaning, pre-treatment, and multiple coating layers, followed by baking to ensure durability and adhesion.
