Product Description
Product Overview
High-quality galvanized steel coils available in non-oiled and slightly oiled surface treatments, manufactured to G3302 standards with 26-28 gauge thickness options.
Hot-Dip Galvanizing Process
Our hot-dip galvanizing process involves reacting molten metal with an iron substrate to create a durable alloy layer. The process includes pickling to remove surface oxides, followed by cleaning in specialized solutions before immersion in the hot-dip bath. This method ensures uniform coating, strong adhesion, and extended service life.

Key Advantages
Our galvanized steel combines physical protection with electrochemical properties of zinc coating for superior performance.
- Machinability: Excellent performance in rolling, coiling, and similar processing operations
- Thermal Resistance: Sustains 315°C environments long-term, with color stability up to 250°C
- High Reflectivity: Reflects heat and light twice as effectively as standard zinc steel sheets, with reflectivity exceeding 0.70 for energy-efficient construction applications
Packaging & Shipping
Each coil is protected with waterproof paper inner packing and galvanized steel outer packing, secured with side guard plates and seven steel bands. Custom packaging available per customer requirements.
