Product Introduction

Zinc aluminum magnesium sheet is a new type of high corrosion resistance coated steel plate. Its coating composition is mainly zinc, which is composed of zinc plus 1.5% – 11% aluminum, 1.5% – 3% magnesium and trace silicon (the proportion of different manufacturers is slightly different). At present, the thickness of Zinc Aluminum Magnesium Steel range that can be produced in China is 0.4-4.0mm, and the width range that can be produced is 580mm-1500mm.

Advantages of Zinc Aluminum Magnesium Steel Sheet

• Plane corrosion resistance

High aluminum zinc aluminum magnesium coating, has significantly better plane corrosion resistance than aluminum zinc coating, and hot-dip pure zinc coating. Under the condition of neutral salt spray test, the time of red rust in high aluminum zinc aluminum magnesium coating, is more than 50% longer than that of aluminum zinc coating with the same thickness. Under the condition of cyclic corrosion test, the time of red rust in high aluminum zinc aluminum magnesium coating is nearly twice longer than that of GL coating with the same coating thickness.

• Corrosion resistance

Notch corrosion resistance the notch corrosion resistance of high aluminum zinc aluminum magnesium coating, is significantly better than that of aluminum zinc coating. Under the condition of neutral salt spray test, the greater the zinc ratio index is, compared with that of aluminum zinc coating, as is the greater the notch corrosion resistance of high aluminum zinc aluminum magnesium coating.

• Cup punching corrosion resistance

Under the condition of neutral salt spray test, the red rust time of high aluminum zinc aluminum magnesium coating, is about twice as long as that of aluminum zinc coating.

• Bending corrosion resistance

Under the condition of neutral salt spray test, the corrosion resistance of high aluminum zinc aluminum magnesium coating after bending is about twice higher than that of aluminum zinc coating.

We have our own Physical & Chemical Testing Center Lab to guarantee our product quality. Our test items & instrument fully meet international standards.

Applications of Zinc Aluminum Magnesium Steel Sheet

Zinc aluminum magnesium steel products are widely used in civil construction (keel ceiling, perforated plate, cable bridge), agricultural livestock products (agricultural breeding shed, steel structure, steel structural accessories, greenhouse, breeding equipment), railway roads, power communication (transmission and distribution high and low voltage switchgear, box type substation outer body), photovoltaic support, automobile motor, industrial refrigeration (cooling tower, large outdoor industrial air conditioning) and other industries.
