鍍(du)(du)鋅鋼板(ban)(ban)(ban)按用(yong)(yong)(yong)(yong)途(tu)又可(ke)分(fen)為一般用(yong)(yong)(yong)(yong)、屋頂(ding)用(yong)(yong)(yong)(yong)、建(jian)筑(zhu)外(wai)側板(ban)(ban)(ban)用(yong)(yong)(yong)(yong)、結構用(yong)(yong)(yong)(yong)、瓦壟板(ban)(ban)(ban)用(yong)(yong)(yong)(yong)、拉伸用(yong)(yong)(yong)(yong)和(he)深沖用(yong)(yong)(yong)(yong)等(deng)鍍(du)(du)鋅鋼板(ban)(ban)(ban)。熱(re)(re)鍍(du)(du)鋅板(ban)(ban)(ban)主(zhu)要應用(yong)(yong)(yong)(yong)于建(jian)筑(zhu)外(wai)用(yong)(yong)(yong)(yong)，建(jian)筑(zhu)內用(yong)(yong)(yong)(yong)，民用(yong)(yong)(yong)(yong)，門(men)窗，家(jia)具，機(ji)械(xie)，電子(zi)及(ji)家(jia)用(yong)(yong)(yong)(yong)電器等(deng)領域。也有(you)機(ji)箱(xiang)用(yong)(yong)(yong)(yong)這個(ge)，不過熱(re)(re)鍍(du)(du)鋅板(ban)(ban)(ban)不放輻射的(de)(de)。空調，冰(bing)箱(xiang)，微(wei)波爐及(ji)其類(lei)似家(jia)電背面的(de)(de)那(nei)個(ge)板(ban)(ban)(ban)就是(shi)熱(re)(re)鍍(du)(du)鋅板(ban)(ban)(ban)。鍍(du)(du)鋅層(ceng)(ceng)通過鈍(dun)化處理(li)，可(ke)減少(shao)潮溫貯運條件下產(chan)生(sheng)折銹蝕(shi)(白銹) 。但這種化學處理(li)的(de)(de)防腐蝕(shi)性能是(shi)有(you)限的(de)(de)，而且，妨(fang)礙大多數涂(tu)料的(de)(de)附著性。這種處理(li)一般不用(yong)(yong)(yong)(yong)在鋅鐵合金鍍(du)(du)層(ceng)(ceng)，除光整(zheng)表(biao)面外(wai)，作為常規，生(sheng)產(chan)廠對其他類(lei)型的(de)(de)鍍(du)(du)鋅層(ceng)(ceng)均進行鈍(dun)化處理(li)。

熱(re)鍍(du)(du)鋅(xin)(xin)生產發展(zhan)一直處于滯后(hou)狀態。20世紀(ji)50年(nian)代(dai)到60年(nian)代(dai)陸續建(jian)成(cheng)了(le)13條單張鋼板熔劑法熱(re)鍍(du)(du)鋅(xin)(xin)機組，能力為10萬(wan)t/a，但因產量低、成(cheng)本高、質量差(cha)、污(wu)染環境、經(jing)濟(ji)效(xiao)益(yi)差(cha)等缺陷(xian)已先(xian)后(hou)停、轉產。從(cong)20世紀(ji)70年(nian)代(dai)末(mo)，我國(guo)才開始建(jian)造大(da)型寬帶熱(re)鍍(du)(du)鋅(xin)(xin)機組。熱(re)鍍(du)(du)鋅(xin)(xin)帶鋼在我國(guo)市場一直是緊缺品(pin)種。從(cong)20世紀(ji)90年(nian)代(dai)中期(qi)以來，每年(nian)都要(yao)從(cong)國(guo)外(wai)進口80-100萬(wan)t左右。隨著國(guo)內(nei)經(jing)濟(ji)的(de)(de)發展(zhan)，尤其是汽車、家電及建(jian)筑業(ye)的(de)(de)發展(zhan)，對(dui)鍍(du)(du)鋅(xin)(xin)帶鋼的(de)(de)需(xu)求量也大(da)大(da)增加(jia)。

鍍鋅管價格鍍鋅卷分熱鍍鋅和電鍍鋅兩種，熱鍍鋅鍍鋅層厚，具有鍍層均勻，附著力強，使用壽命長等優點。瀘州鍍鋅管電鍍鋅成本低，表面不是很光滑，其本身的(de)(de)耐腐蝕性比熱鍍鋅管相差很多(duo)。提起鍍鋅管，可能(neng)沒接觸過建(jian)材的(de)(de)朋友并(bing)不了解。從1935年(nian)建(jian)立一(yi)條連續涂(tu)(tu)層鋼(gang)板(ban)線開始，彩涂(tu)(tu)板(ban)得到了廣(guang)泛(fan)應用，目前彩涂(tu)(tu)板(ban)的(de)(de)品種(zhong)繁多(duo)，大約超過600種(zhong)，彩涂(tu)(tu)板(ban)兼有(you)機(ji)(ji)聚合物與鋼(gang)板(ban)兩(liang)者的(de)(de)優點，既有(you)有(you)機(ji)(ji)聚合物的(de)(de)良好著色性、成型性、耐蝕性、裝飾性、又有(you)鋼(gang)板(ban)的(de)(de)高強度和易加工(gong)性，能(neng)很容易地進(jin)行沖壓裁(cai)剪、彎曲、深沖等加工(gong)。

彩(cai)(cai)(cai)鋼(gang)(gang)是(shi)(shi)指(zhi)彩(cai)(cai)(cai)涂(tu)鋼(gang)(gang)板，彩(cai)(cai)(cai)涂(tu)鋼(gang)(gang)板是(shi)(shi)一(yi)種帶(dai)有(you)有(you)機涂(tu)層的(de)(de)(de)鋼(gang)(gang)板，傳統的(de)(de)(de)涂(tu)層分好幾類，氟(fu)碳涂(tu)層的(de)(de)(de)，幾乎可(ke)以(yi)防腐20年。一(yi)般從鋼(gang)(gang)廠(chang)以(yi)卷筒(tong)的(de)(de)(de)形式分銷到各地。我們經常看(kan)到的(de)(de)(de)彩(cai)(cai)(cai)鋼(gang)(gang)板是(shi)(shi)指(zhi)加工好的(de)(de)(de)板材，厚(hou)度(du)在(zai)50~100mm左右，它是(shi)(shi)由中(zhong)間(jian)的(de)(de)(de)填(tian)料和(he)兩面的(de)(de)(de)彩(cai)(cai)(cai)鋼(gang)(gang)板組成(cheng)。其中(zhong)，彩(cai)(cai)(cai)板厚(hou)度(du)有(you)0.4mm、0.5mm、0.6mm等不(bu)同(tong)的(de)(de)(de)厚(hou)度(du),中(zhong)間(jian)層可(ke)以(yi)是(shi)(shi)聚(ju)胺脂、巖綿(mian)或泡沫(mo)塑料等。由于有(you)專(zhuan)用型材，所以(yi)用彩(cai)(cai)(cai)鋼(gang)(gang)板構筑的(de)(de)(de)廠(chang)房(fang)建(jian)造速度(du)很(hen)快（如(ru)非典時的(de)(de)(de)小湯山(shan)醫(yi)院），但強度(du)低。

重慶鍍(du)鋅(xin)(xin)(xin)板(ban)(ban)(ban)按(an)生產及加(jia)工(gong)方法可(ke)分為(wei)以下幾類： 熱浸鍍(du)鋅(xin)(xin)(xin)鋼(gang)(gang)(gang)(gang)板(ban)(ban)(ban)。將薄鋼(gang)(gang)(gang)(gang)板(ban)(ban)(ban)浸入熔(rong)解(jie)的(de)鋅(xin)(xin)(xin)槽中，使其表(biao)面(mian)粘附一層鋅(xin)(xin)(xin)的(de)薄鋼(gang)(gang)(gang)(gang)板(ban)(ban)(ban)。目前主要采用(yong)連續鍍(du)鋅(xin)(xin)(xin)工(gong)藝生產，即把(ba)成(cheng)(cheng)卷的(de)鋼(gang)(gang)(gang)(gang)板(ban)(ban)(ban)連續浸在熔(rong)解(jie)有(you)(you)鋅(xin)(xin)(xin)的(de)鍍(du)槽中制成(cheng)(cheng)鍍(du)鋅(xin)(xin)(xin)鋼(gang)(gang)(gang)(gang)板(ban)(ban)(ban)； 合金(jin)化(hua)鍍(du)鋅(xin)(xin)(xin)鋼(gang)(gang)(gang)(gang)板(ban)(ban)(ban)。為(wei)克(ke)服單(dan)面(mian)未涂鋅(xin)(xin)(xin)的(de)缺(que)點(dian)，又(you)(you)有(you)(you)一種(zhong)在另面(mian)涂以薄層鋅(xin)(xin)(xin)的(de)鍍(du)鋅(xin)(xin)(xin)板(ban)(ban)(ban)，即雙(shuang)面(mian)差鍍(du)鋅(xin)(xin)(xin)板(ban)(ban)(ban)；合金(jin)、復(fu)合鍍(du)鋅(xin)(xin)(xin)鋼(gang)(gang)(gang)(gang)板(ban)(ban)(ban)。它是用(yong)鋅(xin)(xin)(xin)和其他(ta)金(jin)屬(shu)如鉛、鋅(xin)(xin)(xin)制成(cheng)(cheng)合金(jin)乃至(zhi)復(fu)合鍍(du)成(cheng)(cheng)的(de)鋼(gang)(gang)(gang)(gang)板(ban)(ban)(ban)。這種(zhong)鋼(gang)(gang)(gang)(gang)板(ban)(ban)(ban)既具有(you)(you)防銹性能，又(you)(you)有(you)(you)良好的(de)涂裝性能。
