Pre-painted Galvanized Steel (PPGI) are hot-dip galvanized steel, coated with multiple layers of organic paint using a continuous coil coating process. This provides excellent corrosion resistance, color uniformity, and aesthetic appeal, ideal for construction, appliances, and decorative applications.
