Product Description
Product Overview
Hot-dip galvanized steel coil manufactured with custom thickness options from 3.5mm to 16mm and length specifications tailored to your requirements.
Manufacturing Process
Hot-dip galvanizing involves the reaction of molten metal with an iron substrate to produce an alloy layer, effectively combining the substrate and plating layer. The process includes pickling to remove iron oxide, followed by cleaning in ammonium chloride or zinc chloride solutions before immersion in the hot-dip plating bath. This method ensures uniform coating, strong adhesion, and extended service life.

Key Advantages
Hot-dip galvanized steel offers both physical protection and electrochemical corrosion resistance through zinc coating application.
Machinability
Suitable for rolling, coiling, and similar processing requirements with excellent formability.
Thermal Resistance
Standard HDG steel maintains performance up to 230°C, with color stability at 250°C. Special formulations can withstand environments up to 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 – ideal for energy-efficient construction applications.
Packaging & Shipping
Standard packaging includes waterproof paper inner lining, galvanized or coated steel sheet outer protection, side guard plates, and secure wrapping with seven steel bands. Custom packaging available per customer requirements.
