    ❓ Frequently Asked Questions (FAQ)
    Q What is ZAM steel and how does it differ from regular galvanized steel?
    ZAM steel is a zinc-aluminum-magnesium alloy-coated steel that offers significantly superior corrosion resistance compared to conventional galvanized (pure zinc-coated) steel. In salt spray tests, ZAM steel can last 5–10 times longer than standard galvanized steel, making it ideal for demanding environments.
    Q What thickness and width options are available for ZAM steel?
    ZAM steel is available in thicknesses ranging from 0.3mm to 3.0mm and widths from 600mm to 1500mm, with a coating weight of 60–275 g/m² (double-sided). Custom dimensions can be arranged upon request.
    Q What are the main types of ZAM steel available?
    There are three main types: Standard ZAM (Zn-based with 1–3% Al and 0.1–1% Mg), High-Al ZAM / AZ (5–11% Al and 1–3% Mg for enhanced performance), and Super ZAM (optimized alloy ratios for maximum corrosion resistance).
    Q Is ZAM steel suitable for outdoor and marine environments?
    Yes. ZAM steel is specifically engineered to resist harsh environments including marine, coastal, and industrial areas. Its self-healing property — where magnesium forms a protective layer over scratches — further enhances long-term durability outdoors.
    Q What industries commonly use ZAM steel?
    ZAM steel is widely used in construction (roofing, wall panels, garage doors), home appliances (refrigerator and AC casings), automotive (chassis parts), and agriculture (greenhouse frames, silos) due to its excellent formability and long-lasting corrosion protection.
    Q Which international standards does your ZAM steel comply with?
    Our ZAM steel products comply with major international standards including ASTM, GB/T, and JIS. We ensure strict quality control in carbon content, elongation, and surface defect management to meet the requirements of global markets across SE Asia, the Middle East, Africa, and South America.
