Features
Premium Zinc-Aluminum-Magnesium Steel Coil – SGH440/SGH490/SGH540
Ultra-durable triple-layer alloy coating (Zn-Al-Mg) for exceptional corrosion resistance, 3-6x longer lifespan than standard galvanized steel. Precision-engineered thickness (0.3-3.0mm customizable) ensures structural stability under extreme weather (-40°C to 120°C). Ideal for high-stress applications: roofing, automotive panels, agricultural equipment, and solar mounting systems. Matte finish with minimal spangle for uniform aesthetics and paint adhesion. Direct factory pricing – wholesale orders (20+ tons) ship globally with certified MTC/ISO reports. Custom slit widths (600-1500mm) and anti-fingerprint treatments available.
Key Advantage:
Combines the strength of steel (540MPa tensile) with lightweight Mg/Al rustproofing – 50% lower maintenance cost vs. traditional materials.
