鋅鋁鎂鍍層鋼板是指在現有的熱鍍鋅鍍層中添加了一定量的Al、Mg或在熱鍍鋁鋅鍍層中添加了一定了的Mg元素的鍍層鋼板，具有高耐蝕性、高切邊

保護性能的特點。已公開的實驗室加速實驗、戶外暴露實驗等結果表明，一定范圍內Al、Mg含量增加會提高耐蝕性幾倍到十幾倍。鍍層加Mg之后的

另一大優點是鋼板的切邊耐蝕性提高，含Mg的Zn基腐蝕產物會覆蓋在切口表面，從而對切口形成保護。用途：建筑屋頂、墻面、農業畜牧、家電、

汽車、彩涂基板等。

Zinc aluminum magnesium plating steel plate refers to the plating steel plate with a certain amount of Al, Mg or Mg elements added to the existing hot plating galvanizing coating in the hot plated zinc plating, with the characteristics of high corrosion resistance, high edge cutting protection performance.The results of published laboratory acceleration experiments and outdoor exposure experiments show that the increase of Al and Mg content in a certain range will improve

the corrosion resistance by several to ten times.Another major advantage after plating and Mg is the improved edge corrosion resistance of the steel plate,

and the Zn-based corrosion product containing Mg will cover the incision surface to protect the incision.Use: building roof, wall, agricultural and animal

husbandry, home appliances, cars, color coating substrate, etc.
