樓(lou)(lou)(lou)承(cheng)板(ban)(ban)鍍(du)(du)(du)(du)(du)鋅首(shou)要(yao)起到防腐(fu)的效果，按標準組(zu)合(he)(he)樓(lou)(lou)(lou)板(ban)(ban)與非(fei)組(zu)合(he)(he)樓(lou)(lou)(lou)板(ban)(ban)壓(ya)型(xing)鋼(gang)板(ban)(ban)應(ying)選(xuan)(xuan)(xuan)用(yong)(yong)熱(re)(re)鍍(du)(du)(du)(du)(du)鋅，不該選(xuan)(xuan)(xuan)用(yong)(yong)電鍍(du)(du)(du)(du)(du)鋅鋼(gang)板(ban)(ban)，其雙(shuang)面(mian)鍍(du)(du)(du)(du)(du)鋅層(ceng)總含(han)量(liang)(liang)(liang)(liang)要(yao)滿足在(zai)使用(yong)(yong)期間不致銹(xiu)損的要(yao)求。當(dang)作(zuo)為(wei)非(fei)組(zu)合(he)(he)樓(lou)(lou)(lou)承(cheng)板(ban)(ban)時(shi)(shi)，鍍(du)(du)(du)(du)(du)鋅層(ceng)含(han)量(liang)(liang)(liang)(liang)可選(xuan)(xuan)(xuan)用(yong)(yong)較低(di)值(zhi);當(dang)為(wei)組(zu)合(he)(he)樓(lou)(lou)(lou)承(cheng)板(ban)(ban)時(shi)(shi)，鍍(du)(du)(du)(du)(du)鋅層(ceng)含(han)量(liang)(liang)(liang)(liang)不該小于(yu)150g/m2。當(dang)為(wei)組(zu)合(he)(he)樓(lou)(lou)(lou)板(ban)(ban)且(qie)使用(yong)(yong)環境條件較為(wei)惡(e)劣時(shi)(shi)，鍍(du)(du)(du)(du)(du)鋅層(ceng)含(han)量(liang)(liang)(liang)(liang)應(ying)選(xuan)(xuan)(xuan)用(yong)(yong)上限值(zhi)或(huo)更高值(zhi)。更高的鍍(du)(du)(du)(du)(du)鋅要(yao)求，如雙(shuang)面(mian)鍍(du)(du)(du)(du)(du)鋅量(liang)(liang)(liang)(liang)為(wei)300g/m2、350g/m2或(huo)鍍(du)(du)(du)(du)(du)鋁鋅(5%鋁)275g/m2、300g/m2等(deng)，較高的鍍(du)(du)(du)(du)(du)層(ceng)量(liang)(liang)(liang)(liang)使組(zu)合(he)(he)樓(lou)(lou)(lou)板(ban)(ban)有更長(chang)耐(nai)久性，同等(deng)量(liang)(liang)(liang)(liang)的鍍(du)(du)(du)(du)(du)鋁鋅的防銹(xiu)蝕(shi)才能大約兩(liang)倍(bei)于(yu)一般熱(re)(re)鍍(du)(du)(du)(du)(du)鋅。鍍(du)(du)(du)(du)(du)鋅量(liang)(liang)(liang)(liang)也不是越(yue)厚越(yue)好(hao)，當(dang)鍍(du)(du)(du)(du)(du)鋅量(liang)(liang)(liang)(liang)較厚時(shi)(shi)，抗剪連(lian)接件栓釘的焊接質量(liang)(liang)(liang)(liang)就很難保證，焊接時(shi)(shi)，宜選(xuan)(xuan)(xuan)用(yong)(yong)局(ju)部除鋅處理(li)措施。

鍍鋅(xin)(xin)鋼(gang)(gang)板(ban)(ban)(ban)(ban)為基板(ban)(ban)(ban)(ban)的(de)(de)彩(cai)涂(tu)鋼(gang)(gang)板(ban)(ban)(ban)(ban)，除有(you)鋅(xin)(xin)保護外，鋅(xin)(xin)層(ceng)(ceng)(ceng)上(shang)(shang)的(de)(de)有(you)機涂(tu)層(ceng)(ceng)(ceng)起了覆蓋隔離(li)作用(yong)，可防止鋼(gang)(gang)板(ban)(ban)(ban)(ban)生(sheng)銹，使(shi)用(yong)壽(shou)命(ming)比(bi)鍍鋅(xin)(xin)鋼(gang)(gang)板(ban)(ban)(ban)(ban)更長，據(ju)介紹涂(tu)層(ceng)(ceng)(ceng)鋼(gang)(gang)板(ban)(ban)(ban)(ban)的(de)(de)使(shi)用(yong)壽(shou)命(ming)比(bi)鍍鋅(xin)(xin)鋼(gang)(gang)板(ban)(ban)(ban)(ban)長50%。在連(lian)續機組上(shang)(shang)以(yi)冷軋帶鋼(gang)(gang)，鍍鋅(xin)(xin)帶鋼(gang)(gang)（電鍍鋅(xin)(xin)和(he)熱鍍鋅(xin)(xin)）為基板(ban)(ban)(ban)(ban)，經(jing)(jing)過表(biao)面預處理（脫脂和(he)化學處理），用(yong)輥涂(tu)的(de)(de)方法，涂(tu)上(shang)(shang)一(yi)層(ceng)(ceng)(ceng)或多層(ceng)(ceng)(ceng)液(ye)態涂(tu)料，經(jing)(jing)過烘烤和(he)冷卻所得的(de)(de)板(ban)(ban)(ban)(ban)材即為涂(tu)層(ceng)(ceng)(ceng)鋼(gang)(gang)板(ban)(ban)(ban)(ban)。由于涂(tu)層(ceng)(ceng)(ceng)可以(yi)有(you)各種不同(tong)的(de)(de)顏色，習慣上(shang)(shang)把涂(tu)層(ceng)(ceng)(ceng)鋼(gang)(gang)板(ban)(ban)(ban)(ban)叫做彩(cai)色涂(tu)層(ceng)(ceng)(ceng)鋼(gang)(gang)板(ban)(ban)(ban)(ban)。又由于涂(tu)層(ceng)(ceng)(ceng)是在鋼(gang)(gang)板(ban)(ban)(ban)(ban)成型加工之前進行(xing)的(de)(de)，在國(guo)外這叫做預涂(tu)層(ceng)(ceng)(ceng)鋼(gang)(gang)板(ban)(ban)(ban)(ban)。

河北鍍鋅管重慶鍍鋅板按生產及加工方法可分為以下幾類： 熱浸鍍鋅鋼板。將薄鋼板浸入熔解的鋅槽中，使其表面粘附一層鋅的薄鋼板。目前主要采用連續鍍鋅工藝生產，即把成卷的鋼板連續浸在熔解有鋅的鍍槽中制成鍍鋅鋼板； 合金化鍍鋅鋼板。鍍鋅管批發為克(ke)服單面(mian)未涂鋅的(de)(de)(de)缺點，又(you)有一種在另面(mian)涂以薄層鋅的(de)(de)(de)鍍鋅板(ban)，即(ji)雙面(mian)差鍍鋅板(ban)；合(he)(he)金(jin)(jin)、復合(he)(he)鍍鋅鋼板(ban)。它(ta)是(shi)用鋅和其他金(jin)(jin)屬如鉛、鋅制成合(he)(he)金(jin)(jin)乃至復合(he)(he)鍍成的(de)(de)(de)鋼板(ban)。這(zhe)種鋼板(ban)既具有防銹性(xing)能，又(you)有良好的(de)(de)(de)涂裝性(xing)能。

由于我國鋅(xin)(xin)(xin)資源比較豐(feng)富(fu)，鍍(du)鋅(xin)(xin)(xin)又是(shi)一種(zhong)(zhong)價廉、能(neng)防銹，又能(neng)裝飾的(de)高性(xing)價比鍍(du)種(zhong)(zhong)，因而在汽車、機(ji)械、電(dian)子、船舶、儀表、輕工等(deng)(deng)工業部門(men)得(de)到(dao)廣泛的(de)應用(yong)。如機(ji)械零件、低壓電(dian)器(qi)、高壓開關(guan)、緊固連接件、鋼鐵結構件、建(jian)(jian)筑(zhu)五金(jin)、農業機(ji)械、輕工產(chan)品(pin)(pin)等(deng)(deng)都離不開鍍(du)鋅(xin)(xin)(xin)鈍(dun)化制(zhi)品(pin)(pin)。鍍(du)鋅(xin)(xin)(xin)板卷(juan)(juan)(juan)因此可分為熱軋鍍(du)鋅(xin)(xin)(xin)板卷(juan)(juan)(juan)和冷(leng)軋熱鍍(du)鋅(xin)(xin)(xin)板卷(juan)(juan)(juan)，它們(men)主(zhu)要用(yong)于建(jian)(jian)筑(zhu)、家電(dian)、汽車、容(rong)器(qi)、交通及(ji)家業等(deng)(deng)領(ling)域。特別是(shi)鋼結構建(jian)(jian)筑(zhu)、汽車制(zhi)造(zao)、鋼板倉(cang)制(zhi)造(zao)等(deng)(deng)行業。 重慶鍍(du)鋅(xin)(xin)(xin)卷(juan)(juan)(juan)特點主(zhu)要為：耐腐蝕強、表面質(zhi)量好、得(de)利于深加工、經(jing)濟實用(yong)等(deng)(deng)。
