Zn‑Al‑Mg steel is cold‑rolled substrate coated with zinc‑aluminum‑magnesium alloy. It delivers far better corrosion resistance than ordinary galvanized and galvalume steel, featuring self‑healing performance for cut edges and longer service ,Equipped with advanced production lines and implementing strict full-process quality control, we offer customized ZAM steel coils with a thickness range of 0.20‑1.20 mm and width range of 600‑1500 mm. Our ultra-thin and high-strength ZAM steel features stable mechanical performance and cost competitiveness, winning consistent recognition and long-term cooperation from overseas buyers.
Anti‑fingerprint ZM steel: With transparent passivation film, it resists fingerprints and stains, improves anti‑corrosion property. Suitable for home appliance shells, interior parts and high‑end components.
Non‑anti‑fingerprint ZM steel: No extra anti‑fingerprint treatment, cost‑effective with good bending and stamping performance. Fingerprints may appear after touch. Widely used for roofing, wall panels, solar brackets and PPGI substrates.
Zn‑Al‑Mg steel is widely applied in building roofing, wall panels, solar mounting brackets and PPGI substrate processing. With superior durability and environmental adaptability, our ZAM steel is extensively used in construction, solar energy, home appliances and metal processing industries, adapting to various harsh working environments.
