鍍鋁鋅光板是冷軋鋼帶為基板，經(jīng)過連續(xù)熱浸鍍鋁鋅工藝而生產(chǎn)出來的鍍鋁鋅板產(chǎn)品。 鍍鋁鋅板具有耐腐蝕強、表面質(zhì)量好、得利于深加工、經(jīng)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(lǐng)域。特別是鋼結(jié)構(gòu)建筑、汽車制造、鋼板倉制造等行業(yè)。 鍍鋁鋅板的生產(chǎn)工藝是連續(xù)熔融鍍層工藝。金屬鍍層產(chǎn)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(jīng)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。
