鍍鋅批發熱鍍鋅生產發展一直處于滯后狀態。20世紀50年代到60年代陸續建成了13條單張鋼板熔劑法熱鍍鋅機組，能力為10萬t/a，但因產量低、成本高、質量差、污染環境、經濟效益差等缺陷已先后停、轉產。從20世紀70年代末，我國才開始建造大型寬帶熱鍍鋅機組。安順鍍鋅熱鍍鋅帶鋼在我國市場一直是(shi)(shi)緊缺品種(zhong)。從20世紀(ji)90年(nian)代中期以來，每年(nian)都要從國外進(jin)口80-100萬(wan)t左右。隨著國內(nei)經濟(ji)的(de)發展，尤(you)其是(shi)(shi)汽車(che)、家電及建筑業(ye)的(de)發展，對鍍鋅帶鋼的(de)需(xu)求量也大大增(zeng)加。
