Galvalume Roofing Sheets
55% Al-Zn alloy coated galvalume roofing sheets engineered for maximum heat reflectivity and up to four times the corrosion resistance of standard galvanized steel. We guarantee explicit anti-fingerprint resin integrity, precise structural wave depths, and zero spangle flaking under our global 2-Hour Rapid Quote structural supply program.
Struggling with erratic delivery timelines while your critical project tender deadline closes in? Terrified of receiving thin, low-grade Aluzinc sheets that rust prematurely at the overlapping joints or buckle under high wind loads, failing strict engineering field inspections? Protect your commercial capital and lock in your certified structural testing data immediately.

Technical QA/QC Verification
• 100% Verifiable Material Test Certificates (MTC): Every bulk delivery is backed by detailed documentation conforming strictly to EN 10204 3.1 standards, detailing verified melt heat numbers, yield strengths, chemical alloy compositions, and structural anti-fingerprint surface quality reports. All production runs are fully optimized for third-party auditing via SGS, Bureau Veritas, or Intertek.
• Corporate Financial Security: To mitigate commercial currency and performance volatility for global industrial infrastructure developers, we accept structured trade contracts backed by 100% Irrevocable Letters of Credit (L/C) at sight financial frameworks.
Internal Protection & Ocean Logistics
• Reinforced Tie-Down Palletization & Chocking: Finished panel stacks are mounted onto heavy-duty wood or composite iron structural pallets, bound with multi-pass high-tensile steel tension bands, and fitted with impact-resistant corner protections to prevent structural distortion. The complete payload is securely blocked, strapped, and timber-choked within maritime ocean containers to handle extreme transit swells.
• Extended Port Clearance Buffer (14–21 Days Demurrage): To ensure your local logistics brokers have ample operational windows for terminal customs clearances without incurring heavy administrative penalties, SXY Steel Group provides pre-arranged 14 to 21 days of extended free container demurrage at the discharge port.
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.
