熱(re)(re)鍍鋅(xin)(xin)(xin)卷板現貨消(xiao)(xiao)息：熱(re)(re)鍍鋅(xin)(xin)(xin)產(chan)品廣(guang)泛用(yong)于建筑(zhu)、家電、車船、容器制造業、機電業等，幾乎涉(she)及到衣食住行各(ge)個領域。近(jin)年來，世界(jie)鍍鋅(xin)(xin)(xin)鋼板需求量(liang)不(bu)斷(duan)增加，產(chan)量(liang)增長也(ye)很快，在美、日(ri)等鋼材生產(chan)大(da)國，熱(re)(re)鍍鋅(xin)(xin)(xin)鋼板在鋼材中所(suo)占比例(li)已(yi)高達(da)13%-15%。 熱(re)(re)鍍鋅(xin)(xin)(xin)卷板現貨消(xiao)(xiao)息：近(jin)來，汽車行業越來越重(zhong)視材料的使用(yong)壽命，用(yong)涂(tu)漆冷軋鋼板已(yi)不(bu)能滿足耐(nai)腐蝕(shi)方面的要求。在這種(zhong)情況(kuang)下，耐(nai)腐蝕(shi)性優良且成本低廉的熱(re)(re)鍍鋅(xin)(xin)(xin)板開始普遍受到了(le)汽車廠家的青睞。

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。渝中鍍鋅管在焊接、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。鍍鋅管批發它是用(yong)(yong)鋅和其他金屬如鉛、鋅制成合(he)金乃至(zhi)復合(he)鍍(du)成的鋼(gang)板(ban)。這種鋼(gang)板(ban)既(ji)具有(you)防銹(xiu)性(xing)能(neng)，又(you)有(you)良好的涂裝性(xing)能(neng)。 除上述五種外，還有(you)彩色鍍(du)鋅鋼(gang)板(ban)、印(yin)花涂裝鍍(du)鋅鋼(gang)板(ban)、聚氯乙烯疊層鍍(du)鋅鋼(gang)板(ban)等(deng)。但(dan)目前(qian)常用(yong)(yong)的仍為熱(re)浸(jin)鍍(du)鋅板(ban)。 鍍(du)鋅鋼(gang)板(ban)按用(yong)(yong)途又(you)可分為一般用(yong)(yong)、屋頂用(yong)(yong)、建(jian)筑外側板(ban)用(yong)(yong)、結構用(yong)(yong)、瓦壟(long)板(ban)用(yong)(yong)、拉伸(shen)用(yong)(yong)和深沖用(yong)(yong)等(deng)鍍(du)鋅鋼(gang)板(ban)。
