Zinc Aluminum Magnesium Steel Coil is a kind of alloy metal, generally speaking about the elemental composition of the alloy,

the name is generally sorted according to the content of the metal, the most content is in the front.

So zinc aluminum magnesium refers to zinc alloy, containing a small amount of aluminum and magnesium.

Zinc aluminum magnesium, as the name suggests, is a kind of alloy metal, it is mainly used as steel and steel products surface anti-corrosion treatment,

the beginning is widely used for steel products surface anti-corrosion treatment of metal is pure zinc, with the development of technology improvement,

a variety of tests have been carried out, there have been aluminum zinc alloy and zinc aluminum magnesium alloy and other alloy metal,

increase the effect of metal layer corrosion resistance.

And through a certain aluminum magnesium alloy test, found a better metal ratio to achieve a better anti-corrosion effect.

The Zinc Aluminum-Magnesium coated steel is a new product in the global steel trading industry.

It is a result of various extensive steel manufacturing researches done to enable steelmakers to produce coated steel that is better than galvanized steel. 

This type of coated steel is a highly improved version of a corrosion-resistant steel plate which is made mostly of zinc (Zn),

combined with a set amount of aluminum (Al) and magnesium (Mg).

ZAM coated steels are widely used in different types of construction and can be formed in any kind of steel parts or shape. 

 

The composition of the plating solution of Zinc Aluminum Magnesium Steel Coil is 2% magnesium added on the basis of zinc and aluminum,

which has excellent notch protection performance compared with other coating products.

The zinc flowers（spangle） on the surface of aluminum zinc magnesium and zinc aluminum magnesium plates are delicate, beautiful,

and have good corrosion resistance. The products are widely used in household appliances, construction, structure and other industries.

Firstly, let see what is Z-A-M

What is Z-A-M ?

Z-A-M is short for Zinc Aluminum Magnesium. Z-A-M is a new type of corrosion-resistant coating steel sheet consisting mainly of zinc.

About 11% aluminum, 3% magnesium and trace amounts of silicon. It’s a highly corrosion-resistant hot-dip Zinc-Aluminum-Magnesium alloy coating steel sheet.

Due to the effects of magnesium and aluminum, Z-A-M has excellent corrosion resistance, scratch resistance and formability. 

ZAM Alloy is a new type material which is widely applied in steel industry recently. Compared with galvanized and galvalume.

Its anti-corrosion feature is more superior- almost 10-20 times better, especially popular in salty and moist areas. Then, let’s see the application of the ZAM below.

Application of ZAM Steel Coils:

Zinc aluminum magnesium coil including Al, Mg, Si to improve the corrosion resistance.

In addition to the previous adding Al, it also adds Mg and Si so that rust effect improved obviously. 

Si improves the corrosion resistance of the coating layer containing Al while further improving the corrosion effect by the combined action with Mg.

This Zinc Aluminum Magnesium Alloy Coated Sheet is widely used in construction, road protection, three-dimensional parking lot,

storage equipment, automotive electromechanical equipment and other metal forming areas.

It can manufacture all kinds of steel parts; Corrosion-resistant parts; keel ceilings; Perforated plate; And cable tray.

Where the use of hot-dip galvanized steel or hot-dip galvanized 5% aluminum alloy steel components

after using zinc aluminum magnesium steel coil will be able to achieve better corrosion resistance.

The Advantages of ZAM Steel Coils (Why Choose ZAM?）

1) Zn-Al-Mg coating has better corrosion resistance.

And the increase of Al and Mg content in a certain range makes the corrosion resistance of

Zn-Al-Mg coated steel sheet increase several times times higher than that of galvanized steel sheet.

2) The Zn-Al-Mg coating has good welding performance.

And the addition of magnesium can reduce the spatter of the weld attachment in the laser welding process. And improve the welding performance.

3) Zinc-coated Al-Mg products of ZIDA group, composed of Zn-2.0% Al-1.5Mg.

We can use it in construction, household appliances and automotive industries.

4) Production Specification of ZAM Coils Coating Products :

0.4-2.0mm×1000-1600mm u ZAM coating product specifications:0.4-2.0mm×1000-1600mm

5) Zn-Al-Mg products have higher surface hardness.

The initial dynamic friction coefficient of Zn-Al-Mg products is same as that of Zn products.

But changes little with the increase of friction times. It is favorable for deformation.

6) ZAM steel coils coatings provide the smallest and finest abrasive particles.

Significantly reducing customer downtime for cleaning, tool wear, and reducing dent defects in parts.

7) Zinc-aluminium-magnesium coated steel sheet has the same coating property as pure zinc.

We can use it in many field, such as electrophoresis, post-spraying and color coating raw materials.

8) Because of its excellent corrosion resistance under the film, the corrosion resistance of the coated products can be significantly improved.

9) Corrosion resistance test after color coating showed that the corrosion resistance of the color coated plate

with ZAM as the substrate is significantly better than that of the hot-dip galvanized steel plate.

Thereby delaying the red rust time of the color coated plate and prolonging it. Especially to the ocean and the severe industrial atmosphere.

Because of the composite effect of these added elements. We can improve further the corrosion inhibition effectly.

In addition, it has excellent processing performance (drawing, stamping, bending, painting and welding, etc.)

In Conclusion, under severe conditions, high hardness of coating, and excellent damage resistance.

Compared with common zinc plating and aluminum zinc plating products. The coating with less adhesion can achieve better corrosion resistance.

Because of this strong corrosion resistance. We can use it instead of stainless steel or aluminum in some fields.

The anti-corrosion self-healing effect of the cutting end surface is a major feature of the product.
