What is Hot Dipped PPGI Color Coated Steel Sheet?
Hot dipped PPGI (Pre-Painted Galvanized Iron) color coated steel sheet is a cold-rolled steel base that undergoes hot-dip galvanizing — typically with a zinc coating mass of 60–275 g/m² — followed by chemical treatment, primer application, and a topcoat of polyester, PVDF, or SMP resin. The result is a structurally robust, corrosion-resistant panel available in virtually unlimited color options, combining functional performance with superior visual appeal for both interior and exterior end uses.
Hot Dipped PPGI Color Coated Steel Sheet Manufacturing Process
Production begins with cold-rolled steel coils that are continuously hot-dip galvanized in a molten zinc bath maintained at approximately 450°C, forming a metallurgically bonded zinc-iron alloy layer. The galvanized substrate then passes through a chemical passivation stage before entering a continuous coil coating line, where primer (5–10 µm) and topcoat (15–25 µm) layers are applied via precision roll coaters and cured in high-temperature ovens at 230–260°C peak metal temperature, ensuring optimal paint adhesion and film integrity.
Hot Dipped PPGI Color Coated Steel Sheet Technical Specifications
Our hot dipped PPGI color coated steel sheet is produced to meet ASTM A755, EN 10169, and JIS G3312 standards. Key parameters include: base steel thickness of 0.14–1.20 mm, total coil width of 600–1,250 mm, zinc coating weight of Z60–Z275 (60–275 g/m²), topcoat dry film thickness of 15–25 µm, pencil hardness of H–2H, and T-bend flexibility of 0T–2T. Salt spray resistance exceeds 500 hours per ASTM B117, and tensile strength ranges from 270 to 550 MPa depending on the steel grade selected.
