Zinc Aluminum Magnesium (ZAM), is steel sheets that are produced through a hot-dip method, with a coating that comprises 6% zinc, 3% magnesium, and aluminum. This unique composition grants ZAM outstanding corrosion resistance, preventing rust formation at a level 10-20 times superior to galvanized steel. ZAM coated steel coils is widely employed across various engineering industries, particularly in applications necessitating durability and robust corrosion protection.
Zinc-aluminum-magnesium(zinc aluminum magnesium) coating is through the role of aluminum and magnesium, so that the hot dip coating has excellent corrosion resistance, wear resistance and processing, can be widely used in various fields. Zinc-aluminium-magnesium coated steel plate can be directly replaced by zinc-aluminium-magnesium coated steel plate without changing the existing processing, assembly, coating and other processes.
Most important, our steel sheet service capabilities include slitting,cutting to length, blanking, degreasing and brushing, stretcher leveling and metallurgical support.

Advantages of ZAM coating
● Longer service life than other coated products.
● Cut edge rust protection - the hallmark feature of ZAM.
● Thinner coating yet more protection - ecologically friendly.
● Excellent in severe environments - especially coastal and agricultural.
● Eliminates the need for post dip (batch) galvanizing.
● Superior formability due to coating characteristics Cost savings through longer service life and reduced maintenance.
● Bridges the product gap between heavily coated galvanized and costly stainless steel.

Why choose GNEE zam coated steel coils?
1. Plane corrosion resistance
GNEE ZAM Steel Coils have significantly better plane corrosion resistance than galvanized and hot-dip pure zinc.
Under neutral salt spray test conditions, the time for zam coated steel coils to rust red is more than 50% longer than that of galvanized steel with the same coating thickness.
Under cyclic corrosion test conditions, the time for zam steel coils to rust red is nearly twice as long as that of GL coating with the same coating thickness.
2. Notch corrosion resistance
The notch corrosion resistance of ZAM coated coils is significantly better than that of galvanized steel.
Under neutral salt spray test conditions, the larger the zinc ratio index, the greater the improvement in the notch corrosion resistance of zam coated steel over galvanized steel.
3. Cup corrosion resistance
Under neutral salt spray test conditions, the time for zam steel coating to rust red is about twice as long as that of galvanized steel.
