Pre-painted Aluzinc (Galvalume) Steel (PPGL) are hot-dip Al-Zn alloy – coated steel (55% aluminum, 43.5% zinc, 1.5% silicon) finished with multiple layers of organic paint using a continuous coil coating process. This combination offers superior corrosion resistance, heat reflectivity, and aesthetic appeal—ideal for roofing, siding, appliances, and architectural applications.
