Zn-Al-Mg Steel Coil

Product notes

What is Zn-Al-Mg Steel Coil? Zn Al Mg steel coil is also called Al Zn Mg (AZM)Coating Steel coil, Zinc Aluminum Magnesium steel coil,Aluminum Zinc 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 aluminum, 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! Zn-Al-Mg Steel Coil Material: Material of steel: G250 / G350 / G450 / G550 / A36 / SS400 / S275jr / S235, etc.

Zinc-coating: G20 / G30 / G40 / G60 / G90 / Z40 / Z60 / Z80 / Z100 / Z120 / Z150 / Z275 / Z350, etc.

Product Advantages : 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. 2.

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. 3. excellent alkali resistance and corrosion resistance, and can replace stainless steel in individual fields . 4.

Good scratch resistance 5.

Paintability The paintability of Zn Al Mg (ZAM)Coating Steel coil is similar to that of Galvalume Steel Coil, and it can be painted to further improve the appearance and service life. 6.

Weldability Compared with hot-rolled and cold-rolled sheets, the welding performance of ZAM steel coil is s
