铝锌镁镀层板是一种综合性能非常优秀的合金金属板材，可生产范围为厚度0.15mm~1.2mm、宽度800mm~1250mm。镀层中的锌提供牺牲保护，铝提供钝化保护，镁元素添加后激活了铝元素并降低了镀层的消耗速度，在镀层内部提供屏障式保护，镀层寿命对比传统镀铝锌镀层有了大幅度延长。同时，由于镁元素的添加，在钢板切口处产生镁的化合物，形成隔绝性保护层，可对钢板切口产生良好的保护作用，特别是在特殊环境下，可有效改善钢板切口腐蚀引起的钢板失效问题，大大提升板材的抗腐蚀性能。

Aluminum, zinc and magnesium plating plate is a kind of alloy metal plate with excellent comprehensive performance, with the production range of 0.15mm~1.2mm thickness and the width of 800mm~1250mm.Zinc in the coating provides sacrificial protection, aluminum provides passivation protection, magnesium addition activates aluminum and reduces the consumption speed of the coating, provides barrier protection inside the coating, coating life is greatly extended compared with traditional aluminum zinc plating.At the same time, due to the addition of magnesium elements, magnesium compounds are produced at the steel plate incision, forming an isolated protective layer, which can have a good protective effect on the steel plate incision, especially in the special environment, it can effectively improve the steel plate failure caused by the steel plate incision corrosion, and greatly improve the corrosion resistance of the plate.

铝锌镁产品凭借优良的耐腐蚀性能和切口保护性能，广泛应用于高端工业建筑领域，可满足热轧、铸造、热电、造纸、畜牧养殖、玻璃陶瓷等特殊行业的建筑需求。同时，在沿海等碱性、酸性明显的环境中拥有优异的表现。

With their excellent corrosion resistance and performance of incision protection, aluminum, zinc and magnesium products are widely used in high-grade industrial construction fields, and can meet the construction needs of hot rolling, casting, thermal power, paper making, animal husbandry, glass and ceramics and other special industries.At the same time, in the coastal alkaline, acidic environment has excellent performance.

镀镁铝锌钢板具有优异的耐腐蚀性和良好的加工成形性、焊接性、外观装饰性等，主要应用于建筑行业，正逐步向家电、汽车制造等行业推广应用。国际著名钢铁公司自20世纪80年代起开始研究这种钢板，于21世纪初期先后实现了工业化生产及应用。国内目前仅宝钢、酒钢等少数企业推出了热浸镀锌铝镁合金镀层钢板。

Magnesium coated aluminum zinc steel plate has excellent corrosion resistance and good processing formability, welding, appearance decoration, mainly used in the construction industry, is gradually promoted to home appliances, automobile manufacturing and other industries.International famous steel companies began to study this steel plate since the 1980s, and successively realized the industrial production and application in the early 21st century.At present, only baosteel, Jiteel and other few enterprises have launched hot dip galvanized aluminum magnesium alloy coated steel plate.
