熱(re)鍍鋅(xin)(xin)卷(juan)板價(jia)格(ge)行(xing)業(ye)(ye)統計(ji)數據顯(xian)示，十一(yi)月國(guo)(guo)內粗鋼(gang)日均產量為兩(liang)百(bai)零(ling)九萬噸，環(huan)比(bi)下降3.3%，創出今年(nian)以來水平(ping)，但是當(dang)前減產受到季(ji)(ji)節性因(yin)素(su)支(zhi)撐，市(shi)(shi)場(chang)對(dui)數據有效(xiao)(xiao)性提出質疑。鍍鋅(xin)(xin)卷(juan)工(gong)業(ye)(ye)品而(er)言，近期陸(lu)續公布的重(zhong)要(yao)數據中性偏多。但值(zhi)得注(zhu)意的是，同年(nian)十一(yi)月熱(re)鍍鋅(xin)(xin)卷(juan)板價(jia)格(ge)工(gong)業(ye)(ye)增加(jia)值(zhi)和投資增速放緩(huan)，進(jin)一(yi)步印證了國(guo)(guo)內總(zong)需(xu)求乏(fa)力，工(gong)業(ye)(ye)復蘇形勢(shi)不容樂觀。加(jia)上未來經濟(ji)結構(gou)調整等因(yin)素(su)，工(gong)業(ye)(ye)品價(jia)格(ge)反彈高度將有限。傳(chuan)統需(xu)求淡(dan)季(ji)(ji)效(xiao)(xiao)應還在持續不斷(duan)地發酵，冬(dong)儲效(xiao)(xiao)果不佳。雖然數據顯(xian)示供應壓力開始(shi)減輕，但是目前處(chu)于鋼(gang)鐵(tie)需(xu)求淡(dan)季(ji)(ji)，市(shi)(shi)場(chang)成交萎縮，下游采購遲(chi)遲(chi)未能有效(xiao)(xiao)跟進(jin)，市(shi)(shi)場(chang)信(xin)心不足，鍍鋅(xin)(xin)鋼(gang)板貿(mao)易商囤貨現象也不明(ming)顯(xian)。

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。西昌彩涂卷在焊接、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。彩涂卷廠家它(ta)是用(yong)(yong)鋅和其他金屬如鉛、鋅制成(cheng)合金乃至復合鍍(du)(du)成(cheng)的鋼(gang)(gang)板(ban)(ban)(ban)。這種鋼(gang)(gang)板(ban)(ban)(ban)既具有(you)(you)防銹(xiu)性能(neng)，又有(you)(you)良好的涂裝性能(neng)。 除(chu)上(shang)述(shu)五種外，還有(you)(you)彩色(se)鍍(du)(du)鋅鋼(gang)(gang)板(ban)(ban)(ban)、印花涂裝鍍(du)(du)鋅鋼(gang)(gang)板(ban)(ban)(ban)、聚氯乙烯疊層鍍(du)(du)鋅鋼(gang)(gang)板(ban)(ban)(ban)等。但(dan)目前常用(yong)(yong)的仍(reng)為(wei)熱浸鍍(du)(du)鋅板(ban)(ban)(ban)。 鍍(du)(du)鋅鋼(gang)(gang)板(ban)(ban)(ban)按用(yong)(yong)途又可分為(wei)一般用(yong)(yong)、屋頂用(yong)(yong)、建筑(zhu)外側板(ban)(ban)(ban)用(yong)(yong)、結構用(yong)(yong)、瓦壟板(ban)(ban)(ban)用(yong)(yong)、拉(la)伸用(yong)(yong)和深沖用(yong)(yong)等鍍(du)(du)鋅鋼(gang)(gang)板(ban)(ban)(ban)。
