Premium Corrugated Galvanized Steel Roofing Sheets with Zinc-Aluminum Coating

High-performance 55% Al-Zn alloy coating provides superior corrosion resistance, 3x longer lifespan than standard galvanized sheets. Precision-formed trapezoidal corrugations enhance structural rigidity (load capacity up to 1.5kN/m²) while allowing quick rainwater runoff.

Hot-dip galvanized base steel (275g/m² coating weight) ensures complete rust protection even in coastal areas. UV-resistant surface treatment maintains appearance for over 15 years under direct sunlight.

Ideal for industrial warehouses, agricultural barns, residential roofing, and temporary shelters. Compatible with standard roofing screws for fast installation. Available in custom lengths (0.5-12m) to minimize joint gaps.

Fireproof Class A rating meets international building codes. Matte finish reduces glare while reflecting 85% solar heat. Ships in protective pallets to prevent transit damage.
