Our galvanized steel sheets feature hot-dip zinc coating with exceptional corrosion resistance for indoor and outdoor applications. Available in GI (pure zinc) and GA (zinc-iron alloy) coatings, material strengths range from 250MPa to 700MPa (DX51D-DX56D grades). Standard specifications: thickness 0.12-6.0mm, width 600-2500mm. Compliant with ASTM A653, JIS G3302, EN 10346. Suitable for construction roofing, automotive parts, home appliances, and agricultural equipment. Custom surface treatments (chromated, phosphated, oiled) and spangle control (regular/minimized) available.

Our continuous hot-dip galvanizing line incorporates precision cleaning, annealing, zinc pot coating with air knife control, and post-treatment processes. Equipped with automated coating weight monitoring (±3% tolerance) and tension leveling systems, ensuring uniform zinc distribution and flatness. The hydrogen annealing furnace maintains temperature accuracy within ±5°C, while online spangle control technology enables customized crystallization patterns. Full compliance with international quality standards with third-party certification available.

In order to ensure product quality, we will arrange professional personnel to check product quality, packaging, weight, hardness, etc., according to customer requirements of product specifications, looking for high-quality and cheap cooperative factories in China, to provide customers with one-stop procurement services and quality assurance.

Excellent packaging: waterproof paper and plastic film + iron cover + at least three strapping straps + strapping straps fixed on iron or wood pallets can effectively protect products from corrosion and various climate changes during transportation. Generally speaking, we ship from Shanghai, Tianjin, Qingdao and Ningbo ports. We have worked with many experienced shipping companies for a long time to find the most suitable mode of transportation for you.
