Regular Spangle Passivated Wave Profile Galvanized Corrugated Zinc Roofing Sheet

Dual GI & GL Substrate Options: Available in both hot-dip galvanized (GI) and 55% aluzinc (GL) steel core for targeted corrosion performance.

Customizable Sheet Thickness: Precision cold-rolled in full gauge ranges from 0.12mm to 0.8mm to match specific project strength requirements.

High Zinc & Aluzinc Coating Mass: Flexible zinc/aluzinc coating weights (Z30-Z275 / AZ30-AZ150 g/m2) ensuring long-lasting cathodic rust protection.

Precision Corrugated Wave Geometry: Deep rib profile maximizes structural load capacity, stiffness, and resistance against high wind and storm impacts.

Superior Leak-Proof Overlapping: Tight-fitting side and end lap joints prevent capillary water action, ensuring total watertightness during heavy rain.

High Heat Reflection & Thermal Efficiency: Bright GL/GI metallic finish reflects up to 70% of solar radiation, reducing interior building temperatures.

Passivated & Oiled Anti-White Rust: Chromated, passivated, or lightly oiled surface treatment prevents oxidation marks during long-distance maritime transit.

Tailored Cut-to-Length Delivery: Custom sheet length manufacturing reduces on-site cutting waste, labor overhead, and unnecessary cross-seams.

Strict Standard Compliance: Built to ASTM A653, ASTM A792, EN 10346, and JIS G3302 specifications with full MTC 3.1 quality inspection certificates.

Robust Seaworthy Packaging: Heavy-duty bundle packaging with waterproof plastic lining, VCI paper, outer metal edge guards, and strong steel strapping.
