Hot-dip galvanized steel combines physical barrier protection with electrochemical zinc protection for extended service life in harsh environments.
Designed to withstand rolling, coiling, and forming processes without coating damage or performance degradation.
Maintains structural integrity at temperatures up to 315°C, significantly outperforming standard galvanized steel.
Reflects over 70% of heat and light, providing twice the reflectivity of conventional galvanized steel for energy-saving applications.
Each coil is protected with waterproof paper inner packing, galvanized steel outer packing, side guard plates, and secured with seven steel bands. Custom packaging available upon request.
