Galvanized Roofing Sheets
hot-dip galvanized roofing sheets engineered for reliable civil construction, heavy-duty industrial warehouses, and long-term agricultural outbuildings. We guarantee uniform zero-spangle or regular-spangle zinc crystal distribution, exact corrugation pitch consistency, and maximum structural load performance under our direct 2-Hour Rapid Quote mill program.
Struggling with slow supplier responses while your critical project tender deadline closes in? Terrified of receiving thin, under-spec galvanized sheets that buckle under heavy snow/wind loads or rust prematurely at the overlapping screw joints? Eliminate cross-border purchasing risks and secure your mill-verified testing logs immediately.

Technical QA/QC Verification
• Genuine EN 10204 3.1 Structural Traceability: All shipments include authentic mill test certificates highlighting carbon equivalent metrics, actual yield barriers, structural elongation logs, and exact zinc coating weight tracking. Our processes are perfectly optimized for third-party inspections via SGS, Bureau Veritas, or TÜV.
• Capital Security Guarantee: We eliminate cross-border financial exposure for institutional buyers and general contractors by approving large-volume manufacturing orders under 100% Irrevocable Letters of Credit (L/C) at sight financial frameworks.
Internal Protection & Ocean Logistics
• Secured Tie-Down Palletization & Anti-Shift Container Bracing: Profiled sheets are stacked firmly on heavy wooden or iron chassis pallets, locked tightly with high-tensile steel banding straps, and fitted with thick metal corner shields. The entire payload is blocked, braced, and wood-choked inside the marine container to prevent movement on rough seas.
• Complimentary Extended Destination Port Demurrage: SXY Steel Group automatically includes 14 to 21 days of extended container demurrage at your discharge port, giving your local logistics agents ample operational buffer windows to execute standard international customs clearance.
Characteristics:Weather proof; heating insulation; fireproof; anti-rust; sound insulation; long life span: more than 20 years.
Corrosion Resistance: the aluzinc coating surface protects the base steel not only by providing barrier to corrosion elements, but
also by the sacrificial nature of the coating.
01. SMOOTHNESS
No composite indentation, no residual stress, no deformation after shearing.
02. DECORATIVE
You can choose a realistic material and aesthetic wood grain, stone coating. Patterns and colors can be customized according to
customer requirements.
03. DURABILITY
Surface paint, high gloss retention, good color stability, minimal change in chromatic aberration, and long service time.
04. STABILITY
The change of wind pressure, humidity and temperature will not cause bending, deformation and expansion. It has strong bending and flexural resistance.
