用(yong)(yong)(yong)電鍍(du)法制造這(zhe)種(zhong)鍍(du)鋅(xin)(xin)(xin)(xin)(xin)(xin)(xin)鋼(gang)板(ban)具有良好(hao)的(de)(de)(de)(de)加(jia)工性。但(dan)鍍(du)層較薄，耐(nai)腐蝕性不如(ru)熱(re)浸法鍍(du)鋅(xin)(xin)(xin)(xin)(xin)(xin)(xin)板(ban)；單面(mian)(mian)(mian)(mian)鍍(du)和雙(shuang)(shuang)面(mian)(mian)(mian)(mian)差鍍(du)鋅(xin)(xin)(xin)(xin)(xin)(xin)(xin)鋼(gang)板(ban)。單面(mian)(mian)(mian)(mian)鍍(du)鋅(xin)(xin)(xin)(xin)(xin)(xin)(xin)鋼(gang)板(ban)，即只在一(yi)面(mian)(mian)(mian)(mian)鍍(du)鋅(xin)(xin)(xin)(xin)(xin)(xin)(xin)的(de)(de)(de)(de)產(chan)品。在焊接、涂(tu)裝、防銹(xiu)處理、加(jia)工等方面(mian)(mian)(mian)(mian)，具有比雙(shuang)(shuang)面(mian)(mian)(mian)(mian)鍍(du)鋅(xin)(xin)(xin)(xin)(xin)(xin)(xin)板(ban)好(hao)的(de)(de)(de)(de)適應性。為克服(fu)單面(mian)(mian)(mian)(mian)未涂(tu)鋅(xin)(xin)(xin)(xin)(xin)(xin)(xin)的(de)(de)(de)(de)缺點(dian)，又有一(yi)種(zhong)在另面(mian)(mian)(mian)(mian)涂(tu)以薄層鋅(xin)(xin)(xin)(xin)(xin)(xin)(xin)的(de)(de)(de)(de)鍍(du)鋅(xin)(xin)(xin)(xin)(xin)(xin)(xin)板(ban)，即雙(shuang)(shuang)面(mian)(mian)(mian)(mian)差鍍(du)鋅(xin)(xin)(xin)(xin)(xin)(xin)(xin)板(ban)；合(he)金(jin)、復合(he)鍍(du)鋅(xin)(xin)(xin)(xin)(xin)(xin)(xin)鋼(gang)板(ban)。它是(shi)用(yong)(yong)(yong)鋅(xin)(xin)(xin)(xin)(xin)(xin)(xin)和其他金(jin)屬如(ru)鉛、鋅(xin)(xin)(xin)(xin)(xin)(xin)(xin)制成合(he)金(jin)乃至復合(he)鍍(du)成的(de)(de)(de)(de)鋼(gang)板(ban)。這(zhe)種(zhong)鋼(gang)板(ban)既(ji)具有防銹(xiu)性能，又有良好(hao)的(de)(de)(de)(de)涂(tu)裝性能。 除(chu)上述五(wu)種(zhong)外，還有彩色鍍(du)鋅(xin)(xin)(xin)(xin)(xin)(xin)(xin)鋼(gang)板(ban)、印花涂(tu)裝鍍(du)鋅(xin)(xin)(xin)(xin)(xin)(xin)(xin)鋼(gang)板(ban)、聚氯乙烯(xi)疊層鍍(du)鋅(xin)(xin)(xin)(xin)(xin)(xin)(xin)鋼(gang)板(ban)等。但(dan)目前常用(yong)(yong)(yong)的(de)(de)(de)(de)仍(reng)為熱(re)浸鍍(du)鋅(xin)(xin)(xin)(xin)(xin)(xin)(xin)板(ban)。 鍍(du)鋅(xin)(xin)(xin)(xin)(xin)(xin)(xin)鋼(gang)板(ban)按用(yong)(yong)(yong)途又可分為一(yi)般用(yong)(yong)(yong)、屋頂用(yong)(yong)(yong)、建筑(zhu)外側(ce)板(ban)用(yong)(yong)(yong)、結構用(yong)(yong)(yong)、瓦(wa)壟(long)板(ban)用(yong)(yong)(yong)、拉伸用(yong)(yong)(yong)和深沖用(yong)(yong)(yong)等鍍(du)鋅(xin)(xin)(xin)(xin)(xin)(xin)(xin)鋼(gang)板(ban)。

熱(re)鍍(du)鋅卷板(ban)價(jia)格(ge)(ge)行業(ye)(ye)統計數(shu)(shu)(shu)據(ju)顯(xian)(xian)示(shi)，十一(yi)月國(guo)內(nei)(nei)粗鋼日均(jun)產量為兩百(bai)零九萬噸，環(huan)比下降3.3%，創出(chu)今(jin)年以來水平，但是當前減產受到季節性因素(su)支撐，市(shi)場對數(shu)(shu)(shu)據(ju)有效性提出(chu)質疑。鍍(du)鋅卷工業(ye)(ye)品(pin)而言(yan)，近期陸續公布(bu)的重要數(shu)(shu)(shu)據(ju)中(zhong)性偏多。但值得注意的是，同(tong)年十一(yi)月熱(re)鍍(du)鋅卷板(ban)價(jia)格(ge)(ge)工業(ye)(ye)增加(jia)值和投資增速放緩，進一(yi)步印(yin)證了國(guo)內(nei)(nei)總需求(qiu)乏力(li)，工業(ye)(ye)復蘇形勢(shi)不容樂觀。加(jia)上未來經濟(ji)結構調整等因素(su)，工業(ye)(ye)品(pin)價(jia)格(ge)(ge)反彈高度將有限。傳統需求(qiu)淡季效應還在持(chi)續不斷(duan)地發酵，冬儲(chu)效果(guo)不佳。雖(sui)然(ran)數(shu)(shu)(shu)據(ju)顯(xian)(xian)示(shi)供應壓力(li)開始減輕(qing)，但是目前處于鋼鐵(tie)需求(qiu)淡季，市(shi)場成交萎縮，下游采購遲遲未能(neng)有效跟(gen)進，市(shi)場信心(xin)不足，鍍(du)鋅鋼板(ban)貿易(yi)商囤(dun)貨現象也不明顯(xian)(xian)。

熱鍍鋅鋼管廠家鍍鋅板開平的整個生產來說它首先就是要達到很高的工藝，但是如果要讓它在自己的工藝性上面達到很高的表現，也是要讓它達到很高的要求的，那么它在自己工藝性上面都是要達到什么樣的要求呢？首先一個方面，就是它在自己的生產上面要讓自己有很高的技術，如果是一個廠家，他們沒有很高的技術，那么他們是不能讓自己的工藝性有很好的表現的。達州熱鍍鋅鋼管鍍鋅板(ban)開平的整(zheng)個(ge)(ge)設備上(shang)(shang)面(mian)(mian)也(ye)(ye)是(shi)很重要的，現在(zai)也(ye)(ye)有一(yi)(yi)些廠家，他們因為自(zi)己(ji)(ji)(ji)沒(mei)有很好(hao)的實力，所以(yi)自(zi)然就會讓(rang)它(ta)在(zai)自(zi)己(ji)(ji)(ji)的設備上(shang)(shang)面(mian)(mian)的下(xia)降(jiang)，如果是(shi)一(yi)(yi)些大廠家來說(shuo)，他們在(zai)自(zi)己(ji)(ji)(ji)的整(zheng)個(ge)(ge)工(gong)(gong)作中，都是(shi)能使用(yong)到電腦上(shang)(shang)面(mian)(mian)的控制，但(dan)是(shi)對于有些廠家來說(shuo)，他們還在(zai)使用(yong)一(yi)(yi)些落(luo)后的設備，這樣自(zi)然就會讓(rang)它(ta)在(zai)工(gong)(gong)藝性(xing)上(shang)(shang)面(mian)(mian)下(xia)降(jiang)，所以(yi)這一(yi)(yi)點也(ye)(ye)是(shi)它(ta)在(zai)自(zi)己(ji)(ji)(ji)工(gong)(gong)藝性(xing)上(shang)(shang)面(mian)(mian)的一(yi)(yi)些條件。
