Galvalume Steel Coil is produced through a hot-dip process, coating the base steel with an aluminum-zinc alloy layer (55% aluminum, 43.4% zinc, and 1.6% silicon). It offers exceptional corrosion resistance (withstands over 1,000 hours of salt spray testing, 2-6 times better than regular galvanized steel) and high-temperature resistance (stable for long-term use up to 315°C). Compared to traditional galvanized steel, it achieves the same corrosion protection with 20%-30% thinner coating, while providing superior ductility (supporting 180° bending without cracking), making it ideal for stamping and complex forming processes. This combination ensures both cost efficiency and excellent workability.

Manufactured using continuous galvanizing lines (CGL) equipped with precision zinc coating control systems (air knife system with ±5g/m² accuracy) and advanced annealing processes (hydrogen atmosphere furnaces ensure formability). Integrated with online thickness monitoring and surface scanners for full-process quality control. Annual production capacity exceeds 500,000 metric tons, supporting custom coil weight, ID/OD specifications.

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.
