At Namo Alloy, we provide high-quality Galvanized (GI) and Pre-Painted Galvanized Steel (PPGI) Sheets & Coils designed for maximum environmental resistance. Our Galvanized products feature a uniform zinc coating that provides a sacrificial barrier against rust and oxidation, making them ideal for structural roofing and HVAC ducting. For projects requiring aesthetic appeal, our Pre-Painted (PPGI/PPGL) range offers a wide spectrum of RAL colors with advanced paint systems like RMP, SMP, and PVDF. These sheets are engineered to withstand UV exposure and harsh weather without fading or peeling. Whether for industrial warehouses, residential roofing, or consumer appliances, our sheets are 100% mill-certified to ASTM A653 and IS 277 standards, ensuring precise GSM coating and exceptional paint adhesion.
