Zero-Porosity Welding Galvanized Coil: 0.12-4.0mm Custom Steel | 25-Yr Corrosion Warranty
August 13, 2025
Engineers tackling weld defects now have a breakthrough solution: our 0.12-4.0mm Customizable Galvanized Steel Coil Welding Grade. Its zinc-iron alloy layer (ZF) enables spatter-free welding at 450°C+ while 30-275g/m² customizable zinc coating delivers 1,000+hrs ASTM B117 salt spray resistance. Certified to EN 10142/JIS G3302, it redefines reliability in corrosive environments.
From laser-welded automotive chassis (≤0.1mm HAZ distortion) to EN 1090-2-compliant structural frames, this coil's 340-550MPa tensile strength and zero-spangle surface ensure precision across industries. The chromated+oiled finish guarantees paint-ready surfaces for architectural applications.
HuiYi-GI simplifies global supply: specify zinc coatings (30g/m² indoor to 275g/m² coastal), edge processing, or specialty textures at 5-ton MOQs. Shipped worldwide in VCI/PE-armored packaging within 30 days - backed by a 25-year anti-perforation guarantee.
