What is Zn Al Mg Steel Coil?

Zn Al Mg steel coil is also called Aluminum magnesium zinc coated steel coil,Zn Al Mg (AZM)Coating Steel coil, Zinc Aluminum Magnesium steel coil,Galvanized Alumium Magnesium steel coil. It is a new type of corrosion-resistant coated steel coil.Its coating composition is mainly zinc, which is composed of zinc plus 11% aluminum, 3% magnesium and a small amount of silicon.In addition to the previous addition of Zn and Al, Mg and Si are added to the aluminized magnesium zinc steel coil. The composite effect of these added elements improves the corrosion resistance.Compared with zinc coating and zinc aluminum coating, aluminum magnesium zinc coating has better corrosion resistance.It is a strong corrosion-resistant coated steel plate in the 21st century!

Features of Zn Al Mg steel coil 

  1. Superior corrosion resistance
Al, Mg, Si and other alloying elements are added to the coating of galvanized aluminum-magnesium steel coil, which greatly improves the corrosion inhibition effect of the coating. Compared with ordinary galvanized products, it achieves better corrosion resistance with less coating adhesion. It is 10 to 20 times that of hot-dip galvanized steel coil.
  1. Self-healing ability
When the aluminum-magnesium-zinc steel coil has scratches or cuts, the magnesium, aluminum and zinc dissolved in the coating at the scratches or cuts will form a dense protection composed of zinc hydroxide, alkaline zinc chloride and magnesium hydroxide. The film (white rust) gradually covers the exposed steel base at the scratch or incision part, and separates the external corrosive medium from the exposed steel base, thereby preventing further corrosion of the exposed incision. In this case, the sacrificial anti-corrosion of zinc and the isolation and anti-corrosion of aluminum and magnesium can also play a role.
  1. excellent alkali resistance and corrosion resistance, and can replace stainless steel in individual fields
  1. Good scratch resistance
  1. Paintability
The paintability of Zn Al Mg (AZM)Coating Steel coil is similar to that of Galvalume Steel Coil, and it can be painted to further improve the appearance and service life.
  1. Weldability
Compared with hot-rolled and cold-rolled sheets, the welding performance of Zn Al Mg steel coil is slightly worse, but it can still be welded with a reasonable process and achieve the due strength, which will not affect its use. For the welding part, it can be repaired with Zn-Al paint to achieve the effect similar to the normal coating.
  1. Long service life
Due to the super corrosion resistance of 10-20 times that of ordinary hot-dip galvanized sheets and the corrosion-resistant self-healing effect of the cut section, the service life of components made of galvanized aluminum-magnesium steel coils will naturally be very long. The service life can reach more than 30 years.
The composition of galvanized aluminum-magnesium steel coil is added with Mg-Al-Zn, which has strong and reliable chlorine resistance (table salt/sweat/sea surface/night wind/soil layer) and alkali corrosion resistance, which can be guaranteed for 20-30 years Does not produce red rust.
Most of the plane corrosion of the coated sheet occurs at the scratch, and the scratch is an inevitable phenomenon of the coated sheet, especially during the processing process, if the coated sheet itself has good scratch resistance, it can be very Avoid scratches to a large extent, thereby increasing its service life. Zn Al Mg steel coil is the best, and the load when it produces scratches is about 1.5 times more than that of galvanized-5% aluminum, and more than 3 times that of galvanized and Galvalume Steel Coil. This is because of the higher hardness of its coating.
   8. Zinc Aluminum Magnesium steel coil can produce environmentally friendly products, it does not contain heavy metal ions
