Product Description
Galvanized Steel Coil GI Sheet in Coil Z30-Z275 for Building Materials
Galvanized Steel Coil (GI Coil) is produced by hot-dip galvanizing process, coating a layer of zinc on the surface of cold rolled steel to enhance corrosion resistance and extend service life.
It is widely used in construction, roofing sheets, steel structures, and household appliances due to its excellent durability, cost-effectiveness, and easy processing performance.
Our GI coils are strictly produced according to international standards and are highly welcomed in markets such as Southeast Asia, Middle East, Africa, and South America.
