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。巫溪冷軋板在焊接、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。冷軋板廠家它是用(yong)(yong)鋅(xin)(xin)和其他金(jin)屬如(ru)鉛、鋅(xin)(xin)制(zhi)成(cheng)合(he)金(jin)乃至復合(he)鍍(du)(du)(du)成(cheng)的(de)鋼(gang)板(ban)(ban)。這種(zhong)鋼(gang)板(ban)(ban)既具有防銹性能，又有良好的(de)涂裝性能。 除(chu)上(shang)述五種(zhong)外，還有彩色鍍(du)(du)(du)鋅(xin)(xin)鋼(gang)板(ban)(ban)、印花涂裝鍍(du)(du)(du)鋅(xin)(xin)鋼(gang)板(ban)(ban)、聚氯乙(yi)烯疊(die)層鍍(du)(du)(du)鋅(xin)(xin)鋼(gang)板(ban)(ban)等(deng)。但目前(qian)常用(yong)(yong)的(de)仍為熱(re)浸鍍(du)(du)(du)鋅(xin)(xin)板(ban)(ban)。 鍍(du)(du)(du)鋅(xin)(xin)鋼(gang)板(ban)(ban)按(an)用(yong)(yong)途(tu)又可分為一(yi)般用(yong)(yong)、屋頂(ding)用(yong)(yong)、建筑外側(ce)板(ban)(ban)用(yong)(yong)、結構用(yong)(yong)、瓦壟板(ban)(ban)用(yong)(yong)、拉伸用(yong)(yong)和深沖用(yong)(yong)等(deng)鍍(du)(du)(du)鋅(xin)(xin)鋼(gang)板(ban)(ban)。

熱鍍(du)(du)鋅(xin)(xin)卷(juan)板價(jia)格(ge)(ge)行業統計數據顯(xian)示，十一月國(guo)(guo)內粗鋼(gang)日均產(chan)量為兩百零(ling)九萬噸，環(huan)比(bi)下降(jiang)3.3%，創(chuang)出今年以(yi)來水平，但是當前(qian)減(jian)(jian)產(chan)受到季(ji)節性因(yin)(yin)素支(zhi)撐，市場(chang)對數據有(you)(you)效(xiao)性提出質疑。鍍(du)(du)鋅(xin)(xin)卷(juan)工(gong)業品而(er)言，近期陸續(xu)(xu)公布的重要(yao)數據中性偏多。但值得注意的是，同年十一月熱鍍(du)(du)鋅(xin)(xin)卷(juan)板價(jia)格(ge)(ge)工(gong)業增(zeng)加值和投資增(zeng)速放緩，進一步印證了國(guo)(guo)內總需(xu)(xu)求(qiu)乏(fa)力，工(gong)業復(fu)蘇形勢不容(rong)樂觀(guan)。加上未來經濟結構調整等因(yin)(yin)素，工(gong)業品價(jia)格(ge)(ge)反彈高度(du)將有(you)(you)限。傳統需(xu)(xu)求(qiu)淡(dan)季(ji)效(xiao)應(ying)還在(zai)持(chi)續(xu)(xu)不斷地發酵，冬儲(chu)效(xiao)果不佳。雖然數據顯(xian)示供應(ying)壓力開始減(jian)(jian)輕，但是目前(qian)處于鋼(gang)鐵需(xu)(xu)求(qiu)淡(dan)季(ji)，市場(chang)成(cheng)交萎縮，下游采購(gou)遲遲未能有(you)(you)效(xiao)跟進，市場(chang)信(xin)心不足，鍍(du)(du)鋅(xin)(xin)鋼(gang)板貿易商囤貨現象(xiang)也(ye)不明顯(xian)。

鍍(du)(du)(du)鋅(xin)(xin)鋼(gang)(gang)(gang)(gang)板(ban)(ban)是(shi)為(wei)防止鋼(gang)(gang)(gang)(gang)板(ban)(ban)表面遭受腐(fu)蝕，延長(chang)其使用壽命，在鋼(gang)(gang)(gang)(gang)板(ban)(ban)表面涂(tu)(tu)以一層(ceng)金屬鋅(xin)(xin)，這種(zhong)涂(tu)(tu)鋅(xin)(xin)的(de)(de)(de)薄鋼(gang)(gang)(gang)(gang)板(ban)(ban)稱為(wei)鍍(du)(du)(du)鋅(xin)(xin)板(ban)(ban)。按(an)生產(chan)及加工方(fang)法可(ke)分為(wei)以下幾類：熱浸(jin)(jin)鍍(du)(du)(du)鋅(xin)(xin)鋼(gang)(gang)(gang)(gang)板(ban)(ban)。將(jiang)薄鋼(gang)(gang)(gang)(gang)板(ban)(ban)浸(jin)(jin)入熔 微商貨(huo)源解(jie)的(de)(de)(de)鋅(xin)(xin)槽中，使其表面粘附一層(ceng)鋅(xin)(xin)的(de)(de)(de)薄鋼(gang)(gang)(gang)(gang)板(ban)(ban)。目前(qian)主要采用連(lian)續鍍(du)(du)(du)鋅(xin)(xin)工藝生產(chan)，即(ji)把成(cheng)卷(juan)的(de)(de)(de)鋼(gang)(gang)(gang)(gang)板(ban)(ban)連(lian)續浸(jin)(jin)在熔解(jie)有鋅(xin)(xin)的(de)(de)(de)鍍(du)(du)(du)槽中制成(cheng)鍍(du)(du)(du)鋅(xin)(xin)鋼(gang)(gang)(gang)(gang)板(ban)(ban)；合(he)(he)金化鍍(du)(du)(du)鋅(xin)(xin)鋼(gang)(gang)(gang)(gang)板(ban)(ban)。這種(zhong)鋼(gang)(gang)(gang)(gang)板(ban)(ban)也是(shi)用熱浸(jin)(jin)法制造，但(dan)在出槽后(hou)，立即(ji)把它(ta)加熱到５００℃左(zuo)右(you)，使其生成(cheng)鋅(xin)(xin)和鐵的(de)(de)(de)合(he)(he)金被膜。這種(zhong)鍍(du)(du)(du)鋅(xin)(xin)板(ban)(ban)具有良好(hao)的(de)(de)(de)涂(tu)(tu)料(liao)的(de)(de)(de)密(mi)著性和焊(han)接性。
