熱(re)鍍(du)鋅生產發展(zhan)一(yi)直(zhi)處于滯后(hou)狀(zhuang)態。20世(shi)紀(ji)(ji)50年(nian)(nian)代到(dao)60年(nian)(nian)代陸(lu)續(xu)建成了13條單(dan)張鋼板熔(rong)劑法熱(re)鍍(du)鋅機組(zu)，能(neng)力為10萬t/a，但因產量(liang)低、成本高、質量(liang)差(cha)、污染環(huan)境(jing)、經濟效益差(cha)等缺陷(xian)已先后(hou)停、轉產。從(cong)(cong)20世(shi)紀(ji)(ji)70年(nian)(nian)代末(mo)，我國才開始建造大(da)型(xing)寬帶(dai)熱(re)鍍(du)鋅機組(zu)。熱(re)鍍(du)鋅帶(dai)鋼在(zai)我國市(shi)場一(yi)直(zhi)是緊(jin)缺品種(zhong)。從(cong)(cong)20世(shi)紀(ji)(ji)90年(nian)(nian)代中期以來，每年(nian)(nian)都(dou)要從(cong)(cong)國外進口(kou)80-100萬t左右。隨著國內經濟的(de)發展(zhan)，尤其是汽車(che)、家電及建筑業的(de)發展(zhan)，對鍍(du)鋅帶(dai)鋼的(de)需求量(liang)也大(da)大(da)增加。

C型鋼價格鍍鋅鋼板為基板的彩涂鋼板，除有鋅保護外，鋅層上的有機涂層起了覆蓋隔離作用，可防止鋼板生銹，使用壽命比鍍鋅鋼板更長，據介紹涂層鋼板的使用壽命比鍍鋅鋼板長50%。渝中C型鋼在連(lian)續機組上以冷(leng)軋帶(dai)鋼(gang)(gang)(gang)(gang)，鍍(du)鋅(xin)帶(dai)鋼(gang)(gang)(gang)(gang)（電鍍(du)鋅(xin)和(he)(he)熱(re)鍍(du)鋅(xin)）為(wei)基板(ban)(ban)(ban)，經(jing)過(guo)表面預處理（脫脂和(he)(he)化學(xue)處理），用輥(gun)涂(tu)的(de)方(fang)法(fa)，涂(tu)上一層(ceng)(ceng)(ceng)或多層(ceng)(ceng)(ceng)液態涂(tu)料，經(jing)過(guo)烘(hong)烤和(he)(he)冷(leng)卻所(suo)得的(de)板(ban)(ban)(ban)材(cai)即為(wei)涂(tu)層(ceng)(ceng)(ceng)鋼(gang)(gang)(gang)(gang)板(ban)(ban)(ban)。由(you)于(yu)涂(tu)層(ceng)(ceng)(ceng)可(ke)以有(you)各(ge)種不同的(de)顏色(se)，習慣(guan)上把涂(tu)層(ceng)(ceng)(ceng)鋼(gang)(gang)(gang)(gang)板(ban)(ban)(ban)叫做彩色(se)涂(tu)層(ceng)(ceng)(ceng)鋼(gang)(gang)(gang)(gang)板(ban)(ban)(ban)。又由(you)于(yu)涂(tu)層(ceng)(ceng)(ceng)是在鋼(gang)(gang)(gang)(gang)板(ban)(ban)(ban)成型加工之前進行的(de)，在國外這(zhe)叫做預涂(tu)層(ceng)(ceng)(ceng)鋼(gang)(gang)(gang)(gang)板(ban)(ban)(ban)。
