Our DX51D galvanized steel coils feature advanced hot-dip galvanizing technology with passivation treatment, providing superior corrosion resistance and durability for industrial applications.

Hot-dip galvanizing involves reacting molten zinc with an iron substrate to create a durable alloy layer. The process includes pickling to remove surface oxides, followed by cleaning and immersion in the hot-dip bath, resulting in uniform coating with strong adhesion and extended service life.

• Superior Machinability: Excellent performance in rolling, coiling, and forming operations
• Enhanced Thermal Resistance: Sustains temperatures up to 315°C for extended periods
• High Reflectivity: Reflectivity exceeding 0.70, providing energy-saving benefits
• Dual Protection: Combines physical barrier protection with electrochemical corrosion resistance

Our coils are protected with waterproof paper inner packing, galvanized steel outer packing, side guard plates, and secured with seven steel bands. Custom packaging options available.
