High-quality Dx51D, Dx52D, Dx53D zinc coated corrugated galvanized iron (GI) sheets designed for roofing applications. These 3mm thick sheets provide exceptional durability and corrosion resistance for industrial and construction use.

Hot-dip galvanized coating provides both physical barrier protection and electrochemical cathodic protection, ensuring long-term durability even in harsh environments.

Designed to withstand rolling, coiling, and other fabrication processes without compromising coating integrity.

Maintains structural integrity at temperatures up to 315°C, making it suitable for various industrial applications.

Reflectivity exceeding 0.70 provides excellent heat and light reflection, contributing to energy efficiency in building applications.

Standard packaging includes waterproof paper inner packing with galvanized steel outer packing, side guard plates, and secure wrapping with steel bands. Custom packaging available upon request. Exported worldwide to Europe, Africa, Central Asia, Southeast Asia, Middle East, South America, and North America.

Hot-dip galvanizing involves pickling to remove surface oxides, followed by immersion in molten zinc to create a metallurgical bond between the substrate and coating layer.
