鍍鋁鋅光板是冷軋鋼帶為基板，經過連續(xù)熱浸鍍鋁鋅工藝而生產出來的鍍鋁鋅板產品。 鍍鋁鋅板具有耐腐蝕強、表面質量好、得利于深加工、經濟實用等特點。表面呈特有的光滑、平坦和華麗的星花，基色為銀白色。鋁鋅鋼板的鍍層成份按重量比率分別由55%的鋁和43.4%的鋅，1.6%的硅組成。鍍鋁鋅鋼主要用于建筑、家電、汽車、容器、交通及家業(yè)等領域。特別是鋼結構建筑、汽車制造、鋼板倉制造等行業(yè)。 鍍鋁鋅板的生產工藝是連續(xù)熔融鍍層工藝。金屬鍍層產品的長期耐腐蝕性能主要取決于鍍層物的融解率和鍍層的厚度，鍍鋅鋼板的鍍鋅層融解率比55%鋁鋅合金鍍層的鍍鋁鋅鋼板的融解率高。因此55%鋁鋅合金鍍層的鍍鋁鋅鋼板的使用壽命比鍍鋅鋼板要長，經過20年后約無銹蝕跡，基板采用55%鋁的鋁鋅合金鍍層，其防銹蝕可達50年以上。
