Galvanized Sheets (also called G.I. Sheets) are steel sheets coated with a layer of zinc to provide corrosion resistance and long-lasting durability. The zinc coating protects the steel from rust and environmental damage, making these sheets ideal for outdoor, industrial, and construction applications.
They provide reliable corrosion resistance, strength, and versatility, making them ideal for both structural and protective applications. Their combination of durability and ease of fabrication ensures long-term performance in residential, commercial, and industrial projects.

The main difference in finish between BI (Black Iron) sheets and GI (Galvanized Iron) sheets lies in their surface protection and appearance.
Black iron sheets have minimal corrosion resistance and are less durable in humid, wet, or outdoor environments, as they can rust quickly if not properly coated or painted. They are best suited for indoor or protected applications.
Meanwhile, galvanized iron sheets have a zinc coating that protects against rust, making them more durable in outdoor, humid, or industrial environments. They require less maintenance and are ideal for roofing, siding, and other exposed structures.
Yes, galvanized iron sheets are highly resistant to corrosion and weather exposure. The zinc coating acts as a protective barrier, preventing rust and extending the sheet’s lifespan even in humid, rainy, or industrial environments. Proper installation and occasional maintenance can further enhance their durability.
