What are the advantages of galvanized magnesium aluminum steel sheet compared with ordinary galvanized and galvanized products?

Galvanized aluminum magnesium steel plate is a new type of high corrosion resistance coated steel plate, its coating composition is mainly zinc, by zinc plus 1.5%-11% aluminum, 1.5%-3% magnesium and trace silicon composition (different manufacturers slightly different proportions).

Advantages

The thickness range of the steel plate can be produced is 0.27mm– 9.00mm, and the width range can be produced is: 580mm– 1524mm. Due to the compound effect of these added elements, the corrosion inhibition effect is further improved. In addition, it has excellent machining performance under severe conditions (drawing, stamping, bending, painting, welding, etc.), high hardness of the coating and excellent damage resistance.

Compared with ordinary galvanized and aluminized zinc products, it has better corrosion resistance, and can be used instead of stainless steel or aluminum in some areas because of this superior corrosion resistance. The corrosion-resistant self-healing effect of the cut section is a major feature of the product.

What is the main role of zinc magnesium aluminum plate?

The world’s best quality aluminum-plated magnesium zinc plate is the SuperDyma, referred to as SD board, developed successfully by Nippon Steel mills in the early 20th century, and its full name should be aluminum-plated magnesium zinc (silicon) board. Silicon is a kind of promoting element, which can make the aluminized zinc magnesium plate have the function of section self-healing after being added in proper proportion.

For example, due to the need of measurement, we need to cut the SD board in the length direction. After cutting the broken end of the steel plate without a protective film, according to common sense, it will gradually react electrolytically with oxygen and water in the atmosphere to rust, but due to the fluidity of magnesium ions, it will flow in the fracture site that is not covered by the protective film to form a new protective film. This means using a hard tool to scratch or break the protective film on the surface of the steel plate.

Therefore, the zinc aluminum magnesium steel plate is mainly used as the surface anti-corrosion treatment of steel and steel products, including a variety of zinc series coating and a large number of steel parts.

With the continuous development of technology, zinc aluminum magnesium steel plate due to excellent corrosion resistance and good processing formability and other properties, is widely used in civil construction (keel ceiling, porous plate, cable bridge), agricultural livestock production (agricultural feeding greenhouse steel structure, steel structure accessories, greenhouse, feeding equipment), railway roads, Electric power communication (transmission and distribution of high and low voltage switchgear, box-type substation), auto motor, industrial refrigeration, cooling tower, large outdoor air conditioning) used in industry and other industries.
