鍍(du)鋅(xin)鋼板(ban)(ban)(ban)(ban)按用(yong)(yong)(yong)(yong)(yong)途又可分(fen)為(wei)一般(ban)用(yong)(yong)(yong)(yong)(yong)、屋頂用(yong)(yong)(yong)(yong)(yong)、建筑(zhu)(zhu)外側板(ban)(ban)(ban)(ban)用(yong)(yong)(yong)(yong)(yong)、結構用(yong)(yong)(yong)(yong)(yong)、瓦壟板(ban)(ban)(ban)(ban)用(yong)(yong)(yong)(yong)(yong)、拉(la)伸(shen)用(yong)(yong)(yong)(yong)(yong)和深沖用(yong)(yong)(yong)(yong)(yong)等鍍(du)鋅(xin)鋼板(ban)(ban)(ban)(ban)。熱鍍(du)鋅(xin)板(ban)(ban)(ban)(ban)主要應用(yong)(yong)(yong)(yong)(yong)于建筑(zhu)(zhu)外用(yong)(yong)(yong)(yong)(yong)，建筑(zhu)(zhu)內用(yong)(yong)(yong)(yong)(yong)，民用(yong)(yong)(yong)(yong)(yong)，門(men)窗，家(jia)具，機械，電子(zi)及(ji)(ji)家(jia)用(yong)(yong)(yong)(yong)(yong)電器等領域。也(ye)有機箱用(yong)(yong)(yong)(yong)(yong)這個，不(bu)過熱鍍(du)鋅(xin)板(ban)(ban)(ban)(ban)不(bu)放輻射的(de)。空調，冰箱，微波爐及(ji)(ji)其類似(si)家(jia)電背(bei)面的(de)那個板(ban)(ban)(ban)(ban)就是(shi)熱鍍(du)鋅(xin)板(ban)(ban)(ban)(ban)。鍍(du)鋅(xin)層(ceng)通過鈍化處理，可減少潮溫貯(zhu)運條件下產(chan)生折銹(xiu)蝕(白銹(xiu)) 。但這種化學(xue)處理的(de)防(fang)腐蝕性能是(shi)有限的(de)，而且，妨(fang)礙大多數(shu)涂料的(de)附著性。這種處理一般(ban)不(bu)用(yong)(yong)(yong)(yong)(yong)在鋅(xin)鐵合(he)金(jin)鍍(du)層(ceng)，除光整表面外，作為(wei)常(chang)規，生產(chan)廠對其他類型(xing)的(de)鍍(du)鋅(xin)層(ceng)均進(jin)行鈍化處理。

鍍鋅鋼管價格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。江油鍍鋅鋼管熱鍍鋅(xin)帶鋼(gang)在我國市場(chang)一直是緊缺品種。從20世(shi)紀(ji)90年代中期以來，每年都要從國外進口80-100萬t左(zuo)右(you)。隨著國內經濟的(de)(de)發(fa)(fa)展，尤(you)其是汽車、家電及建筑(zhu)業的(de)(de)發(fa)(fa)展，對(dui)鍍鋅(xin)帶鋼(gang)的(de)(de)需求量也大(da)大(da)增(zeng)加。

由于(yu)我國鋅(xin)資源比(bi)較(jiao)豐富，鍍(du)(du)(du)鋅(xin)又是一(yi)種價(jia)廉、能防銹，又能裝飾的高性價(jia)比(bi)鍍(du)(du)(du)種，因(yin)而(er)在汽(qi)車、機(ji)械(xie)、電子(zi)、船舶(bo)、儀表(biao)、輕(qing)工等(deng)(deng)工業(ye)(ye)部門得到廣泛(fan)的應(ying)用(yong)。如機(ji)械(xie)零(ling)件(jian)、低壓(ya)電器、高壓(ya)開關、緊固連接件(jian)、鋼(gang)鐵結(jie)構件(jian)、建筑(zhu)五金、農業(ye)(ye)機(ji)械(xie)、輕(qing)工產品(pin)等(deng)(deng)都離不(bu)開鍍(du)(du)(du)鋅(xin)鈍化制(zhi)(zhi)品(pin)。鍍(du)(du)(du)鋅(xin)板(ban)卷因(yin)此可分為(wei)熱(re)軋鍍(du)(du)(du)鋅(xin)板(ban)卷和冷軋熱(re)鍍(du)(du)(du)鋅(xin)板(ban)卷，它(ta)們主要(yao)用(yong)于(yu)建筑(zhu)、家電、汽(qi)車、容器、交通及家業(ye)(ye)等(deng)(deng)領域。特(te)別是鋼(gang)結(jie)構建筑(zhu)、汽(qi)車制(zhi)(zhi)造(zao)、鋼(gang)板(ban)倉(cang)制(zhi)(zhi)造(zao)等(deng)(deng)行業(ye)(ye)。 重慶鍍(du)(du)(du)鋅(xin)卷特(te)點主要(yao)為(wei)：耐腐蝕強、表(biao)面(mian)質量好、得利(li)于(yu)深加工、經(jing)濟實用(yong)等(deng)(deng)。
