Our Galvalume coils (Al-Zn alloy coating) provide exceptional durability with significantly enhanced corrosion resistance compared to traditional galvanized steel. The unique coating microstructure offers excellent heat reflectivity and oxidation resistance under continuous high-temperature environments. Available in a wide range of coating weights and tensile strength grades, with custom widths and surface treatment options (regular spangle, minimal spangle, chromate passivation). Ideal for roofing, HVAC systems, industrial furnaces, and agricultural equipment.

Our Galvalume coils are produced through continuous hot-dip processing lines featuring computer-controlled coating bath (Al-Zn alloy temperature maintained at ±3°C) and precision gas wiping system (coating weight tolerance ±2g/m²). The integrated production system includes hydrogen atmosphere annealing furnaces, rapid cooling sections, and online surface defect detection. Fully automated control ensures perfect coating uniformity and adherence to international standards, with customized coating composition and special performance requirements 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.
