PPGL Color Coated Steel | Prepainted Galvalume Coil | Color Coated Galvalume Sheet

PPGL (Pre-painted Galvalume Steel) represents a premium pre-coated steel solution utilizing galvalume steel as the base substrate. The core material features a ternary alloy coating composed of 55% aluminum, 43.5% zinc, and 1.5% silicon, applied through continuous hot-dip galvanizing process to form a dense intermetallic compound layer. The organic coating is then applied via precision roll coating system and cured through baking process. Our production adopts two-coat two-bake continuous line technology, ensuring uniform coating adhesion and consistent color performance, resulting in a composite material combining protective functionality and decorative aesthetics.
