Hot-rolled galvanized steel is a metal material produced by applying a hot-dip galvanizing process to hot-rolled steel sheets. It combines the high strength and good toughness of hot-rolled steel with the corrosion resistance of the zinc coating, making it widely used in construction, structural engineering, transportation, and machinery manufacturing.

Hot Rolled Galvanized Steel Production Process
Hot rolled galvanized steel uses hot-rolled steel plate as its base material. Through the hot-dip galvanizing process, a uniform and highly adherent zinc layer is formed on its surface, providing excellent corrosion resistance and high mechanical strength.
Advanced Processing
- Cutting: Wanzhi offers high-precision slitting and cut-to-length processing, capable of cutting wide coils or large sheets into specific widths and lengths as required.
- Stamping: Utilizing large-scale stamping equipment, we transform sheets into complex-shaped components, including GI perforated sheets and galvanized stamped panels.
- Bending: Wanzhi performs cold bending to form structural members at various angles, such as C-channels, Z-channels (purlins), and channel sections.
- Roll Forming: Wanzhi’s roll forming production lines directly shape galvanized coils into long-length products with specific cross-sections, including galvanized roofing panels, galvanized wall panels, galvanized guardrail panels, and cable trays.
- Welding: Wanzhi offers welding services including spot welding and MIG/MAG welding.
Surface Treatment
- Phosphating: Forms a water-insoluble phosphate protective layer on galvanized steel surfaces.
- Oiling: Applies a thin layer of rust-preventive oil to galvanized steel surfaces.
- Passivation: Forms a dense passivation film on galvanized steel surfaces.
- Process: Treated using chromate or chromate-free passivation solutions.
- Color Coating / PPGI: Applies primer and topcoat to galvanized steel substrates.
Advantages and Applications of Hot-Rolled Galvanized Steel
Hot-rolled galvanized steel offers corrosion resistance, strength and toughness, formability and weldability, along with excellent coating adhesion. It plays a vital role across sectors including construction, industrial production, energy, and transportation.
