Galvanized aluminum-magnesium coil
Unmatched Corrosion Resistance
The unique Aluminium-Magnesium-Zinc coating forms a dense, self-healing protective layer, offering 3-6 times longer lifespan than standard galvanized steel, especially in harsh environments (coastal, industrial).
Superior Cut-Edge Protection
Its innovative coating provides outstanding sacrificial protection at cut edges and scratches, preventing red rust from spreading—a critical advantage over traditional GI sheets.
Excellent Formability and Paintability
Exhibits superior flexibility and adhesion for bending, stamping, and deep drawing. The surface ensures excellent paint adhesion and coating durability.
Sustainable & Low Lifetime Cost
The extremely long service life reduces replacement frequency and maintenance needs, offering the lowest total cost of ownership and a greener solution.
Our Zinc-Aluminum-Magnesium (ZAM) Coils feature a ZnAlMg ternary alloy coating, delivering exceptional corrosion resistance that far surpasses traditional galvanized materials. The product forms a dense protective layer with self-healing properties, providing excellent cut-edge corrosion resistance. Available in a wide range of coating weights and steel strength grades, with customized widths and surface treatments supported. Ideal for demanding applications such as agricultural construction, photovoltaic mounting systems, and automotive components.
Our Zinc-Aluminum-Magnesium (ZAM) coils are manufactured using continuous hot-dip galvanizing (CGL) technology, equipped with a computer-controlled ZnAlMg alloy coating bath (temperature control ±2°C) and a precision air-knife system (coating weight accuracy ±3g/m²). The production line integrates a hydrogen-protected annealing furnace, high-speed roll coater, and online surface inspection system to ensure coating uniformity and zero surface defects. The fully automated process control system complies with international standards such as ASTM A1046/A1046M and JIS G3321, supporting customized coating compositions and special performance requirements.
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.
