锌铝镁镀层是一种综合性能非常优秀的镀层产品。锌铝镁镀层的耐蚀性远远高于镀锌和镀铝锌，对切断口的保护非常优良，焊接性能也很好，坊间传闻开发的目的是为了用于替代某些不锈钢的应用场景。在国内光伏农场建设刚刚兴起时，锌铝镁钢板常被用于制造光伏支架。日本（东横inn顶楼的线缆桥架）和青海（光伏农场支架）的旅游途中都有这种产品的实际应用。切断口附近明显的镀层腐蚀后流淌覆盖的痕迹是这种的产品的一个明显特征。

Zinc, aluminum and magnesium coating is a coating product with very excellent comprehensive performance.The corrosion resistance of zinc aluminum magnesium coating is much higher than that of galvanizing and aluminum plated zinc, the protection of the cutting mouth is very excellent, and the welding performance is also very good. It is rumored that the development is to replace some stainless steel application scenarios.When the construction of domestic photovoltaic farms was just emerging, zinc aluminum magnesium steel plate was often used to make photovoltaic bracket.Japan (the cable bridge on the top floor of the East horizontal inn) and Qinghai (photovoltaic farm support) all have practical applications of this product.The trace of the coating flowing covered after corrosion near the cut port is a clear feature of this product.

镀锌铝镁钢板同其他镀锌类钢板一样，易受低熔点金属镀层的影响。在电弧电焊中，与热轧、冷轧钢板相比，容易出现飞溅和气孔的增加以及由于裂纹而造成强度下降等。但是，如果条件选择适当，焊接接缝就不会存在连接强度的问题。

Galvanized aluminum magnesium steel plate, like other galvanized steel plate, is susceptible to low melting point metal plating.In arc welding, compared with hot rolled and cold rolled steel plates, it is easy to increase in splash and pores and cause strength decline due to cracks.However, if the conditions are chosen properly, there will be no connection strength problem in the welding joints.
