HOT DIPPED ZN-AL-MG ALLOY STEEL COIL

Hot-dip galvanized steel coil: smooth surface, excellent performance, can be used in automobiles, refrigerators, washing machines and other home appliances, as well as industrial equipment, a variety of building materials. General finished product thickness: 0.17-1.6mm, finished product width 700-1260mm. Coil inner diameter: 508mm, 610mm.

Galvanized aluminum magnesium steel plate is a new type of high corrosion resistance coating 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), mainly used as steel and steel products surface anti-corrosion treatment, including a variety of zinc series of coating and a large number of steel parts of the whole dip plating anti-corrosion. With the continuous development of technology, zinc-aluminum-magnesium alloy coated steel plate is mainly used in the construction industry because of its excellent corrosion resistance and good processability, weldability, appearance decoration, etc., and is gradually being promoted and applied to household appliances, automobile manufacturing and other industries.

International famous steel companies such as Nippon Steel, Nippon Steel, ThyssenKrupp began to study this steel plate in the 1980s, and it has realized industrial production and application in the early 21st century. In 4 years ago, the domestic use of zinc, aluminum and magnesium products basically rely on Japan, South Korea and other countries to import, and with the continuous fermentation of photovoltaic field in recent years, in addition to state-owned steel mills such as Baosteel, Jiusteel, Shougang, Tang steel and other in the production of zinc, aluminum and magnesium products, there are also a large number of private steel mills into, such as Tianjin Xinyu, Hebei Zhaojian, etc., there are also some strip steel production enterprises to join the industry. At present, the thickness range that can be produced in China is 0.4mm-4.0mm, and the width range that can be produced is 580mm-2080mm. At present, the steel mills producing zinc aluminum magnesium coil in China are mainly low aluminum zinc aluminum magnesium, only a few enterprises can produce medium (high) aluminum zinc aluminum magnesium, such as Shougang has a full series of zinc aluminum magnesium, and has the only production line in the country that can provide zinc aluminum magnesium coated steel plate with a thickness of 3.0 mm or more.
