What is Zinc Aluminum Magnesium Coated Steel
This zinc-aluminum-magnesium coated steel plate, also called ZAM coated steel plate, is a newly developed coated steel plate with a coating thickness of 100-450g+/-10g and has strong corrosion resistance. Zinc-aluminum-magnesium coated steel plate is a new type of corrosion-resistant coated steel plate. The main component is zinc, containing about 11% aluminum, 3% magnesium and trace amounts of silicon. Our zinc-aluminum-magnesium coated steel adds Al, Mg, and Si on the basis of traditional galvanizing. These added chemical elements improve corrosion resistance. That is to say, in addition to the previous addition of Al, elements that have a significant effect on Mg are added to the zinc-aluminum-magnesium coil products. In addition, the addition of Si must be satisfied, so that the anti-rust effect can be improved. Si improves the corrosion resistance of Al-containing coatings, and further improves the corrosion effect by combining with Mg. This zinc-aluminum-magnesium steel has excellent corrosion resistance on surfaces, bent workpieces, ammonia environments, cutting edges, and drawn workpieces. Its HS code is 72109000.
Advantages of zinc-aluminum-magnesium coated steel
1. Excellent anti-rust performance! The rust-proof performance of flat parts goes without saying.
2. The anti-rust performance of the end face is also excellent.
3. In addition, it has excellent alkali resistance. Compared with hot-dip galvanized steel and hot-dip galvanized 5% aluminum alloy steel, this zinc-aluminum-magnesium steel coil can achieve the same corrosion resistance, but uses less coating. In addition, due to its excellent red rust resistance, it can be used to replace stainless steel or aluminum plates.
4. Excellent processing performance! The curved and stretched parts are not easy to rust, and the surface processing is not rarely damaged, making it very beautiful.
5. Weldability and paint resistance are also very good.
6. Plating adhesion can withstand harsh processing. In addition, the coating has high hardness and excellent damage resistance.
7. Super VA new material can greatly reduce costs and shorten delivery time because it does not require post-plating.
8. Can also replace stainless steel and aluminum.
9. Resistant to bonding processing under harsh conditions. In addition to its high hardness coating, it also has excellent damage resistance.

Uses of zinc-aluminum-magnesium steel
Zinc-aluminum-magnesium alloy coated sheets are widely used in metal forming fields such as construction, road protection, three-dimensional parking lots, warehousing equipment, and automotive electromechanical equipment. It can manufacture various steel parts, corrosion-resistant parts, keel ceilings, perforated panels, and cable trays. Better corrosion resistance can be achieved by using hot-dip galvanized steel sheets or hot-dip galvanized 5% aluminum alloy steel components followed by zinc-aluminum-magnesium steel coils. When construction after galvanizing or painting is required, switching to zinc-aluminum-magnesium coils can save the post-galvanizing and painting processes, thereby reducing costs and shortening delivery time. The corrosion resistance of zinc-aluminum-magnesium coated coils and its color steel is five times that of ordinary galvanized steel sheets, which solves the problem of color steel easily rusting in coastal areas and also solves the problem of short service life of color steel sheets. Color steel is suitable for applications in structural engineering, power engineering, purification engineering, photovoltaic design, etc.
