熱(re)鍍(du)(du)(du)(du)鋅(xin)(xin)板和電(dian)鍍(du)(du)(du)(du)鋅(xin)(xin)板在鍍(du)(du)(du)(du)鋅(xin)(xin)量上有很(hen)(hen)大的(de)(de)差別，就像(xiang)山東彩涂卷）。熱(re)鍍(du)(du)(du)(du)鋅(xin)(xin)的(de)(de)鍍(du)(du)(du)(du)鋅(xin)(xin)量不(bu)可能(neng)太小(xiao)，一(yi)般(ban)(ban)(ban)較(jiao)小(xiao)為(wei)雙面50～60g／m2，較(jiao)大可達600g／m2。電(dian)鍍(du)(du)(du)(du)鋅(xin)(xin)板的(de)(de)鍍(du)(du)(du)(du)鋅(xin)(xin)層可以很(hen)(hen)薄(bo)，較(jiao)小(xiao)達15g／m2，但要求鍍(du)(du)(du)(du)層較(jiao)厚的(de)(de)話則(ze)生產線(xian)速(su)度很(hen)(hen)慢(man)，不(bu)適應(ying)現代化機組的(de)(de)工(gong)藝特點，一(yi)般(ban)(ban)(ban)較(jiao)大為(wei)lO0g／m2左(zuo)右(you)。正因(yin)為(wei)如此，電(dian)鍍(du)(du)(du)(du)鋅(xin)(xin)板的(de)(de)生產受到(dao)很(hen)(hen)大的(de)(de)限制。工(gong)一(yi)般(ban)(ban)(ban)電(dian)鍍(du)(du)(du)(du)鋅(xin)(xin)比較(jiao)多，適用于(yu)小(xiao)部(bu)件(jian)；熱(re)鍍(du)(du)(du)(du)鋅(xin)(xin)一(yi)般(ban)(ban)(ban)用于(yu)電(dian)力設備(bei)和構件(jian)，適用于(yu)大的(de)(de)部(bu)件(jian)和設備(bei)。當(dang)然他(ta)們的(de)(de)價(jia)格也(ye)相對便(bian)宜一(yi)些(xie)。建設部(bu)已正式(shi)下文，淘(tao)汰技術落后的(de)(de)冷鍍(du)(du)(du)(du)鋅(xin)(xin)管，不(bu)準(zhun)用冷鍍(du)(du)(du)(du)鋅(xin)(xin)管作水、煤氣管。

長春鍍鋅板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。鍍鋅板價格為克服單面未涂鋅(xin)(xin)的缺點，又有(you)(you)一種在另面涂以薄層鋅(xin)(xin)的鍍(du)鋅(xin)(xin)板(ban)(ban)，即雙面差(cha)鍍(du)鋅(xin)(xin)板(ban)(ban)；合(he)金、復合(he)鍍(du)鋅(xin)(xin)鋼板(ban)(ban)。它是用(yong)鋅(xin)(xin)和其他金屬如鉛、鋅(xin)(xin)制成合(he)金乃(nai)至復合(he)鍍(du)成的鋼板(ban)(ban)。這種鋼板(ban)(ban)既具(ju)有(you)(you)防銹性能，又有(you)(you)良好的涂裝性能。

我國建(jian)筑業中，噪聲污染問題久為人(ren)(ren)們所(suo)詬病。輕(qing)型(xing)樓承(cheng)(cheng)板的(de)應用(yong)使得土建(jian)建(jian)筑物局面被打破，集環境破壞(huai)及污染少、材料回收(shou)和(he)利用(yong)率高、符(fu)合可持續(xu)發展要求等(deng)眾多(duo)(duo)優點(dian)(dian)于一(yi)身的(de)樓承(cheng)(cheng)板建(jian)筑應運而生，逐步(bu)被人(ren)(ren)們所(suo)接受。輕(qing)型(xing)樓承(cheng)(cheng)板是近(jin)十年(nian)來發展較快的(de)領(ling)域，在(zai)采用(yong)輕(qing)型(xing)樓承(cheng)(cheng)板占非住宅建(jian)筑投資的(de)50%以(yi)上。這(zhe)種結(jie)構(gou)工業化(hua)、商品化(hua)程度高，施(shi)工快，綜(zong)合效益高，市場需求量很(hen)大，已(yi)引(yin)起(qi)結(jie)構(gou)設計人(ren)(ren)員認識。樓承(cheng)(cheng)板的(de)研究開發已(yi)在(zai)各地(di)試點(dian)(dian)，是輕(qing)鋼發展的(de)一(yi)個重(zhong)要方向，目前已(yi)經有多(duo)(duo)種的(de)低層、多(duo)(duo)層和(he)高層的(de)設計方案和(he)實例。

樓(lou)承板鍍(du)(du)鋅(xin)(xin)首要(yao)(yao)起到防腐的(de)(de)效果(guo)，按標準(zhun)組(zu)合(he)樓(lou)板與非組(zu)合(he)樓(lou)板壓(ya)型(xing)鋼板應選(xuan)用(yong)熱鍍(du)(du)鋅(xin)(xin)，不(bu)該(gai)選(xuan)用(yong)電鍍(du)(du)鋅(xin)(xin)鋼板，其雙(shuang)面鍍(du)(du)鋅(xin)(xin)層(ceng)總(zong)含(han)量(liang)(liang)要(yao)(yao)滿(man)足在使(shi)用(yong)期間(jian)不(bu)致銹(xiu)損的(de)(de)要(yao)(yao)求。當作為(wei)(wei)非組(zu)合(he)樓(lou)承板時(shi)(shi)(shi)，鍍(du)(du)鋅(xin)(xin)層(ceng)含(han)量(liang)(liang)可選(xuan)用(yong)較低值(zhi);當為(wei)(wei)組(zu)合(he)樓(lou)承板時(shi)(shi)(shi)，鍍(du)(du)鋅(xin)(xin)層(ceng)含(han)量(liang)(liang)不(bu)該(gai)小于(yu)150g/m2。當為(wei)(wei)組(zu)合(he)樓(lou)板且使(shi)用(yong)環境(jing)條件較為(wei)(wei)惡劣時(shi)(shi)(shi)，鍍(du)(du)鋅(xin)(xin)層(ceng)含(han)量(liang)(liang)應選(xuan)用(yong)上限值(zhi)或更(geng)高值(zhi)。更(geng)高的(de)(de)鍍(du)(du)鋅(xin)(xin)要(yao)(yao)求，如雙(shuang)面鍍(du)(du)鋅(xin)(xin)量(liang)(liang)為(wei)(wei)300g/m2、350g/m2或鍍(du)(du)鋁鋅(xin)(xin)(5%鋁)275g/m2、300g/m2等(deng)(deng)，較高的(de)(de)鍍(du)(du)層(ceng)量(liang)(liang)使(shi)組(zu)合(he)樓(lou)板有更(geng)長(chang)耐久性，同等(deng)(deng)量(liang)(liang)的(de)(de)鍍(du)(du)鋁鋅(xin)(xin)的(de)(de)防銹(xiu)蝕才能大(da)約兩倍于(yu)一般(ban)熱鍍(du)(du)鋅(xin)(xin)。鍍(du)(du)鋅(xin)(xin)量(liang)(liang)也不(bu)是越厚越好，當鍍(du)(du)鋅(xin)(xin)量(liang)(liang)較厚時(shi)(shi)(shi)，抗剪連接件栓釘的(de)(de)焊接質(zhi)量(liang)(liang)就很難保證(zheng)，焊接時(shi)(shi)(shi)，宜(yi)選(xuan)用(yong)局部除鋅(xin)(xin)處理(li)措(cuo)施。
