Custom Color Trapezoidal Profile Prepainted Galvanized Metal Roofing Sheet

Classic Wave Corrugated Profile: Engineered with continuous sinus/wavy ribs to optimize rainwater runoff speed and deliver high flexural load capacity.

PPGI & GI Dual Protection: Built on a hot-dip galvanized steel core with a high-performance color coating for double-layer atmospheric corrosion resistance.

Superior Leak-Proof Overlapping: Precision-stamped rib geometry ensures tight side-lap and end-lap fitting, completely blocking storm-driven water seepage.

High Wind & Impact Resistance: Reinforced corrugated geometry significantly increases sheet rigidity against harsh weather, heavy winds, and hail impacts.

UV & Fade Resistant Paint Finish: Premium PE/PVDF topcoat system offers long-lasting color retention, resisting UV degradation, chalking, and flaking.

Lightweight & Fast Installation: High strength-to-weight ratio simplifies structural support design, manual handling, on-site cutting, and screw fastening.

Standard DX51D Commercial Grade: Premium DX51D substrate guarantees uniform mechanical properties, high ductility, and reliable structural stability.

Customizable Lengths & RAL Colors: Available in cut-to-length sizes to minimize site scrap, featuring a broad choice of classic RAL color options.

Strict International Compliance: Manufactured in full accord with ASTM A755, EN 10169, and JIS G3312 standards, supported by MTC 3.1 certification.
