用電鍍法制造這種鍍鋅鋼板具有良好的加工性。但鍍層較薄，耐腐蝕性不如熱浸法鍍鋅板；單面鍍和雙面差鍍鋅鋼板。單面鍍鋅鋼板，即只在一面鍍鋅的產品。永川鍍鋅鋼板在焊接、涂裝、防銹處理、加工等方面，具有比雙面鍍鋅板好的適應性。為克服單面未涂鋅的缺點，又有一種在另面涂以薄層鋅的鍍鋅板，即雙面差鍍鋅板；合金、復合鍍鋅鋼板。鍍鋅鋼板廠家它是用(yong)(yong)(yong)鋅(xin)和(he)其他金屬如鉛、鋅(xin)制成(cheng)合金乃至(zhi)復(fu)合鍍(du)(du)成(cheng)的(de)(de)鋼板(ban)。這種(zhong)(zhong)鋼板(ban)既具(ju)有(you)防銹性(xing)能，又有(you)良好的(de)(de)涂裝性(xing)能。 除(chu)上述五(wu)種(zhong)(zhong)外，還有(you)彩色(se)鍍(du)(du)鋅(xin)鋼板(ban)、印花(hua)涂裝鍍(du)(du)鋅(xin)鋼板(ban)、聚氯乙烯疊(die)層(ceng)鍍(du)(du)鋅(xin)鋼板(ban)等。但目前常用(yong)(yong)(yong)的(de)(de)仍(reng)為熱浸鍍(du)(du)鋅(xin)板(ban)。 鍍(du)(du)鋅(xin)鋼板(ban)按(an)用(yong)(yong)(yong)途又可分為一(yi)般(ban)用(yong)(yong)(yong)、屋頂(ding)用(yong)(yong)(yong)、建筑(zhu)外側板(ban)用(yong)(yong)(yong)、結構用(yong)(yong)(yong)、瓦壟板(ban)用(yong)(yong)(yong)、拉伸用(yong)(yong)(yong)和(he)深(shen)沖用(yong)(yong)(yong)等鍍(du)(du)鋅(xin)鋼板(ban)。

熱(re)(re)鍍(du)鋅卷板價(jia)格(ge)行業統計(ji)數(shu)據顯示，十(shi)一(yi)月(yue)國內粗(cu)鋼日均(jun)產(chan)量為(wei)兩(liang)百零(ling)九(jiu)萬噸，環比下(xia)降3.3%，創出(chu)今年(nian)以(yi)來水(shui)平(ping)，但是當(dang)前減產(chan)受到(dao)季(ji)節(jie)性因素支撐，市(shi)(shi)場對數(shu)據有(you)效性提出(chu)質(zhi)疑。鍍(du)鋅卷工業品而言，近期陸續(xu)公(gong)布(bu)的(de)重要(yao)數(shu)據中性偏多。但值得(de)注意的(de)是，同年(nian)十(shi)一(yi)月(yue)熱(re)(re)鍍(du)鋅卷板價(jia)格(ge)工業增加值和投資增速放緩，進(jin)一(yi)步印證了國內總(zong)需(xu)求(qiu)(qiu)乏力(li)，工業復蘇形勢不(bu)容樂觀(guan)。加上(shang)未(wei)來經濟結構調(diao)整(zheng)等(deng)因素，工業品價(jia)格(ge)反彈高度將有(you)限。傳統需(xu)求(qiu)(qiu)淡季(ji)效應還(huan)在持續(xu)不(bu)斷(duan)地(di)發(fa)酵(jiao)，冬儲效果不(bu)佳。雖然數(shu)據顯示供應壓力(li)開(kai)始減輕，但是目前處于鋼鐵(tie)需(xu)求(qiu)(qiu)淡季(ji)，市(shi)(shi)場成(cheng)交萎縮，下(xia)游采(cai)購遲遲未(wei)能有(you)效跟進(jin)，市(shi)(shi)場信心不(bu)足，鍍(du)鋅鋼板貿(mao)易商囤貨現象也不(bu)明顯。

鍍鋅(xin)(xin)(xin)(xin)帶(dai)鋼(gang)(gang)的(de)(de)(de)鋅(xin)(xin)(xin)(xin)層(ceng)特性 電鍍鋅(xin)(xin)(xin)(xin)層(ceng)是不能形成鋅(xin)(xin)(xin)(xin)花(hua)(hua)的(de)(de)(de)，熱鍍鋅(xin)(xin)(xin)(xin)層(ceng)則有(you)鋅(xin)(xin)(xin)(xin)花(hua)(hua)，其形成過程如下：當鍍鋅(xin)(xin)(xin)(xin)帶(dai)從鋅(xin)(xin)(xin)(xin)鍋(guo)出來后(hou)，經氣刀的(de)(de)(de)噴吹，大(da)量(liang)(liang)鋅(xin)(xin)(xin)(xin)液被吹回鋅(xin)(xin)(xin)(xin)鍋(guo)，這(zhe)時帶(dai)鋼(gang)(gang)表面還有(you)純(chun)鋅(xin)(xin)(xin)(xin)層(ceng)，呈液 態附(fu)在(zai)鋼(gang)(gang)板表面，在(zai)鋼(gang)(gang)板表面形成大(da)量(liang)(liang)結(jie)晶(jing)核，隨著鋼(gang)(gang)板上升(sheng)冷(leng)卻，使結(jie)晶(jing)核慢慢長成鋅(xin)(xin)(xin)(xin)花(hua)(hua)。冷(leng)卻速度越快鋅(xin)(xin)(xin)(xin)花(hua)(hua)越小，冷(leng)卻速度越慢鋅(xin)(xin)(xin)(xin)花(hua)(hua)越大(da)。熱鍍鋅(xin)(xin)(xin)(xin)帶(dai)鋼(gang)(gang)在(zai)我國市場一(yi)直是緊缺品(pin)種。從20世紀(ji)90年(nian)(nian)代中期以來，每年(nian)(nian)都(dou)要(yao)從國外進(jin)口(kou)80-100萬t左右(you)。隨著國內經濟(ji)的(de)(de)(de)發展(zhan)，尤其是汽(qi)車、家(jia)電及(ji)建(jian)筑(zhu)業(ye)的(de)(de)(de)發展(zhan)，對鍍鋅(xin)(xin)(xin)(xin)帶(dai)鋼(gang)(gang)的(de)(de)(de)需求量(liang)(liang)也大(da)大(da)增加。
