What is Zn-Al-Mg275 Color Coated Steel?

Zn-Al-Mg275 HDP Steel combines triple-layer Zn-(2-11%)Al-(1.5-3%)Mg alloy coating (275g/m²) with 35μm High Durability Polyester (HDP) finish. Engineered for maximum solar reflectance and corrosion resistance in photovoltaic systems and industrial architecture.

Key Features
1.Superior Solar Reflectivity

    Technology: 86.5% SRI (ASTM E1980) via light-reflective ceramic pigments.
    Energy Impact: Reduces rooftop temp. by 15-20°C, cutting cooling costs by 30%+.
2.Extreme Corrosion Resistance

    Coating Innovation: Zn-Al-Mg275 alloy + HDP topcoat forms self-healing barrier.
    Proven Durability: 12,000 hrs salt spray test (ISO 9227) – survives C4 marine environments.
3.Self-Cleaning Hydrophobic Surface

    Functional Design: 25° water contact angle prevents dust accumulation.
    Low Maintenance: Maintains >85% reflectivity after 10 years (vs. 60% for standard panels).
4.Structural Strength & Lightweight

    Material Advantage: Dx51d base (550MPa yield) at 1.0mm thickness – 30% lighter than concrete.
    Installation Efficiency: Enables 100m+ span roofing without supports.

FAQ

Q1: Why choose Zn-Al-Mg over galvanized steel for solar farms?

A: 8× longer lifespan (12,000 vs. 1,500 hrs salt spray) and self-cleaning surface maintain energy output.

Q2: How does 86.5% SRI impact energy savings?

A: Reduces cooling costs by $0.84/m²/year and qualifies for LEED SSc7.1 credits (Heat Island Reduction).

Q3: Can it withstand coastal environments?

A: Yes. Certified for C4 corrosion class (ISO 9223) – ideal for offshore solar/coastal factories.

Q4: Do you provide custom processing?

A: Yes. Slitting, embossing, and perforation services available for PV mounting systems.
