Product Description
Product Overview
Hot-dip galvanizing involves reacting molten metal with an iron substrate to create an alloy layer that bonds the substrate and plating layer. The process begins with pickling to remove iron oxide from steel surfaces, followed by cleaning in ammonium chloride or zinc chloride solutions before immersion in the hot-dip plating bath. This method provides uniform coating, strong adhesion, and extended service life.

Key Advantages
Our galvanized steel combines physical protective features with electrochemical protective properties of zinc coating.
Machinability
Excellent performance for rolling, coiling, and similar processing requirements.
Thermal Resistance
Standard HDG steel operates effectively up to 230°C with color changes at 250°C, while maintaining structural integrity at 315°C for extended periods.
High Reflectivity
Reflects heat and light twice as effectively as standard hot-dip zinc steel sheets, with reflectivity exceeding 0.70 for optimal energy efficiency in construction applications.
