Hot-dip galvanized roof panels are made from high-quality low-carbon steel substrate (DX51D+Z) and processed through continuous hot-dip galvanizing, ensuring an even zinc coating. They are suitable for large-span roof systems in industrial plants and storage buildings.

Core Parameters
Base Material Thickness: 0.35~1.2mm (tolerance ±0.03mm)
Zinc Coating Weight: Z180~Z275 (180~275g/m²)
Effective Coverage Width: 750~1200mm (customizable)
Wave Height/Wave Spacing: 25~130mm (available in various profiles such as trapezoidal and sinusoidal waves)

Performance Advantages
✔ Superior Weather Resistance:
Salt spray test ≥ 1000 hours (ASTM B117)
Adaptability to temperature differences of -40°C to 120°C
✔ Structural Design:
Hidden screw fixing system (wind-resistant design)
Longitudinal overlap uses self-locking edge technology

Certification Standards
China: GB/T 12754-2019
International: ASTM A792, EN 10346
Environmental Protection: RoHS chromium-free passivation treatment
