Product DescriptionTIMES STEEL AdvantagesChina's Leading Zn-Al-Mg Coated Steel Supplier (75+ Countries Served)First to Achieve 86.5% Solar Reflectance Index (SRI) with Nano-Ceramic HDP Coating12,000 Hours Salt Spray Resistance – 8× Lifespan vs. Galvanized SteelDaily Stock 7,000-12,000 Tons | Standard Specs Delivered in 7-15 DaysWhat 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 Features1.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.SpecificationModel NO.DX51D+ZM275CertificationISO, RoHS, IBRSurface TreatmentCoatedTechniqueCold RolledApplicationConstruction,Household,Automobile,PhotovoltaicEdgeSlit edgeStockStockThickness0.15mm-6mmWidth5mm-1600mmCoil Weight3-8mtCoil ID508/610mmCoating40-450G/M2Delivery Time3-15 daysAcceptable quotation termsFOB / CIF / CFR / EXWAcceptable payment termsTT / LCApplication ScenariosSolar Power PlantsIndustrial RoofsPV Mounting Systems, BackrailsMaximizes energy yield per m2Warehouses, Factories, Logistics CentersZero corrosion + HVAC cost savingsCool Roof SystemsAgricultureUrban Buildings in Hot ClimatesUHI mitigation + LEED creditsGreenhouse Roofs, Livestock SheltersOptimizes light diffusionPacking & DeliveryCompany ProfileFAQQ1: 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.
