重慶鍍(du)鋅(xin)(xin)(xin)板按生(sheng)產及加工方(fang)法可分為(wei)以(yi)下(xia)幾類： 熱浸(jin)(jin)鍍(du)鋅(xin)(xin)(xin)鋼(gang)板。將薄(bo)鋼(gang)板浸(jin)(jin)入(ru)熔(rong)解(jie)的(de)(de)(de)鋅(xin)(xin)(xin)槽中，使其(qi)表面(mian)粘附一層鋅(xin)(xin)(xin)的(de)(de)(de)薄(bo)鋼(gang)板。目前主要采用(yong)連(lian)續鍍(du)鋅(xin)(xin)(xin)工藝生(sheng)產，即把(ba)成卷的(de)(de)(de)鋼(gang)板連(lian)續浸(jin)(jin)在熔(rong)解(jie)有(you)鋅(xin)(xin)(xin)的(de)(de)(de)鍍(du)槽中制(zhi)成鍍(du)鋅(xin)(xin)(xin)鋼(gang)板； 合金化鍍(du)鋅(xin)(xin)(xin)鋼(gang)板。為(wei)克服單面(mian)未涂(tu)鋅(xin)(xin)(xin)的(de)(de)(de)缺點(dian)，又有(you)一種在另(ling)面(mian)涂(tu)以(yi)薄(bo)層鋅(xin)(xin)(xin)的(de)(de)(de)鍍(du)鋅(xin)(xin)(xin)板，即雙面(mian)差鍍(du)鋅(xin)(xin)(xin)板；合金、復合鍍(du)鋅(xin)(xin)(xin)鋼(gang)板。它(ta)是(shi)用(yong)鋅(xin)(xin)(xin)和其(qi)他金屬如鉛(qian)、鋅(xin)(xin)(xin)制(zhi)成合金乃至復合鍍(du)成的(de)(de)(de)鋼(gang)板。這種鋼(gang)板既具有(you)防銹(xiu)性能，又有(you)良好的(de)(de)(de)涂(tu)裝性能。

鍍(du)(du)鋅(xin)(xin)(xin)鋼(gang)(gang)(gang)(gang)板(ban)(ban)(ban)(ban)是為(wei)防(fang)止鋼(gang)(gang)(gang)(gang)板(ban)(ban)(ban)(ban)表(biao)面(mian)遭(zao)受腐(fu)蝕(shi)，延長其使用(yong)壽(shou)命(ming)，在(zai)(zai)鋼(gang)(gang)(gang)(gang)板(ban)(ban)(ban)(ban)表(biao)面(mian)涂(tu)以一層(ceng)金(jin)(jin)屬鋅(xin)(xin)(xin)，這種(zhong)涂(tu)鋅(xin)(xin)(xin)的(de)(de)(de)(de)(de)薄(bo)鋼(gang)(gang)(gang)(gang)板(ban)(ban)(ban)(ban)稱為(wei)鍍(du)(du)鋅(xin)(xin)(xin)板(ban)(ban)(ban)(ban)。鋼(gang)(gang)(gang)(gang)板(ban)(ban)(ban)(ban)也是用(yong)熱浸(jin)(jin)(jin)法(fa)制(zhi)(zhi)造，但(dan)在(zai)(zai)出槽后，立即(ji)把(ba)(ba)它加熱到(dao)(dao)500℃左右，使其生成(cheng)(cheng)鋅(xin)(xin)(xin)和鐵的(de)(de)(de)(de)(de)合金(jin)(jin)被(bei)(bei)膜。這種(zhong)鍍(du)(du)鋅(xin)(xin)(xin)卷具有(you)良好的(de)(de)(de)(de)(de)涂(tu)料的(de)(de)(de)(de)(de)密著(zhu)性(xing)(xing)和焊(han)接性(xing)(xing)。合金(jin)(jin)化鍍(du)(du)鋅(xin)(xin)(xin)鋼(gang)(gang)(gang)(gang)板(ban)(ban)(ban)(ban)。這種(zhong)鋼(gang)(gang)(gang)(gang)板(ban)(ban)(ban)(ban)也是用(yong)熱浸(jin)(jin)(jin)法(fa)制(zhi)(zhi)造，但(dan)在(zai)(zai)出槽后，立即(ji)把(ba)(ba)它加熱到(dao)(dao)500℃左右，使其生成(cheng)(cheng)鋅(xin)(xin)(xin)和鐵的(de)(de)(de)(de)(de)合金(jin)(jin)被(bei)(bei)膜。這種(zhong)鍍(du)(du)鋅(xin)(xin)(xin)板(ban)(ban)(ban)(ban)具有(you)良好的(de)(de)(de)(de)(de)涂(tu)料的(de)(de)(de)(de)(de)密著(zhu)性(xing)(xing)和焊(han)接性(xing)(xing)。熱浸(jin)(jin)(jin)鍍(du)(du)鋅(xin)(xin)(xin)鋼(gang)(gang)(gang)(gang)板(ban)(ban)(ban)(ban)。將薄(bo)鋼(gang)(gang)(gang)(gang)板(ban)(ban)(ban)(ban)浸(jin)(jin)(jin)入熔(rong)解的(de)(de)(de)(de)(de)鋅(xin)(xin)(xin)槽中，使其表(biao)面(mian)粘(zhan)附一層(ceng)鋅(xin)(xin)(xin)的(de)(de)(de)(de)(de)薄(bo)鋼(gang)(gang)(gang)(gang)板(ban)(ban)(ban)(ban)。目前主要采用(yong)連續鍍(du)(du)鋅(xin)(xin)(xin)工藝生產，即(ji)把(ba)(ba)成(cheng)(cheng)卷的(de)(de)(de)(de)(de)鋼(gang)(gang)(gang)(gang)板(ban)(ban)(ban)(ban)連續浸(jin)(jin)(jin)在(zai)(zai)熔(rong)解有(you)鋅(xin)(xin)(xin)的(de)(de)(de)(de)(de)鍍(du)(du)槽中制(zhi)(zhi)成(cheng)(cheng)鍍(du)(du)鋅(xin)(xin)(xin)鋼(gang)(gang)(gang)(gang)板(ban)(ban)(ban)(ban)。合金(jin)(jin)、復(fu)合鍍(du)(du)鋅(xin)(xin)(xin)鋼(gang)(gang)(gang)(gang)板(ban)(ban)(ban)(ban)。它是用(yong)鋅(xin)(xin)(xin)和其他金(jin)(jin)屬如鉛、鋅(xin)(xin)(xin)制(zhi)(zhi)成(cheng)(cheng)合金(jin)(jin)乃至復(fu)合鍍(du)(du)成(cheng)(cheng)的(de)(de)(de)(de)(de)鋼(gang)(gang)(gang)(gang)板(ban)(ban)(ban)(ban)。這種(zhong)鋼(gang)(gang)(gang)(gang)板(ban)(ban)(ban)(ban)既具有(you)防(fang)銹性(xing)(xing)能，又(you)有(you)良好的(de)(de)(de)(de)(de)涂(tu)裝性(xing)(xing)能。

首先，在鋼結構樓層板中要達到耐火1.5小時，總的來說可以選擇開口板、縮口板、閉口板三大類。銅梁鍍鋅帶鋼規范上混凝土要高于開口板肋頂之上80mm，并且板底需配置板底受力筋。還有一種就是再開口板底部刷防火涂料，涂料厚度大于等于15,這樣的話，只要達到構造要求高于肋頂5公分就可以了。鍍鋅帶鋼批發而縮口(kou)板和閉口(kou)板，只需(xu)要總的樓板厚度(du)大于(yu)(yu)等于(yu)(yu)110即可(ke)，但是(shi)縮口(kou)板雖然在防火(huo)方(fang)面比開口(kou)板要好。但是(shi)底(di)部還是(shi)需(xu)要加板底(di)受力筋(jin)，而閉口(kou)板則不需(xu)要。

用(yong)(yong)(yong)電鍍(du)(du)(du)法制(zhi)造這種(zhong)(zhong)(zhong)鍍(du)(du)(du)鋅(xin)(xin)鋼(gang)(gang)(gang)板(ban)(ban)(ban)具(ju)有(you)良好(hao)的(de)(de)(de)加工(gong)性。但鍍(du)(du)(du)層較薄，耐腐(fu)蝕性不如熱浸(jin)法鍍(du)(du)(du)鋅(xin)(xin)板(ban)(ban)(ban)；單面(mian)(mian)鍍(du)(du)(du)和雙面(mian)(mian)差鍍(du)(du)(du)鋅(xin)(xin)鋼(gang)(gang)(gang)板(ban)(ban)(ban)。單面(mian)(mian)鍍(du)(du)(du)鋅(xin)(xin)鋼(gang)(gang)(gang)板(ban)(ban)(ban)，即只在(zai)一(yi)面(mian)(mian)鍍(du)(du)(du)鋅(xin)(xin)的(de)(de)(de)產品。在(zai)焊(han)接、涂(tu)裝(zhuang)、防銹(xiu)處(chu)理、加工(gong)等方面(mian)(mian)，具(ju)有(you)比(bi)雙面(mian)(mian)鍍(du)(du)(du)鋅(xin)(xin)板(ban)(ban)(ban)好(hao)的(de)(de)(de)適應性。為(wei)克(ke)服單面(mian)(mian)未涂(tu)鋅(xin)(xin)的(de)(de)(de)缺點，又(you)有(you)一(yi)種(zhong)(zhong)(zhong)在(zai)另面(mian)(mian)涂(tu)以(yi)薄層鋅(xin)(xin)的(de)(de)(de)鍍(du)(du)(du)鋅(xin)(xin)板(ban)(ban)(ban)，即雙面(mian)(mian)差鍍(du)(du)(du)鋅(xin)(xin)板(ban)(ban)(ban)；合(he)(he)金、復(fu)(fu)合(he)(he)鍍(du)(du)(du)鋅(xin)(xin)鋼(gang)(gang)(gang)板(ban)(ban)(ban)。它是用(yong)(yong)(yong)鋅(xin)(xin)和其他金屬(shu)如鉛、鋅(xin)(xin)制(zhi)成合(he)(he)金乃至(zhi)復(fu)(fu)合(he)(he)鍍(du)(du)(du)成的(de)(de)(de)鋼(gang)(gang)(gang)板(ban)(ban)(ban)。這種(zhong)(zhong)(zhong)鋼(gang)(gang)(gang)板(ban)(ban)(ban)既具(ju)有(you)防銹(xiu)性能，又(you)有(you)良好(hao)的(de)(de)(de)涂(tu)裝(zhuang)性能。 除上述五(wu)種(zhong)(zhong)(zhong)外，還有(you)彩(cai)色鍍(du)(du)(du)鋅(xin)(xin)鋼(gang)(gang)(gang)板(ban)(ban)(ban)、印花涂(tu)裝(zhuang)鍍(du)(du)(du)鋅(xin)(xin)鋼(gang)(gang)(gang)板(ban)(ban)(ban)、聚氯乙(yi)烯疊層鍍(du)(du)(du)鋅(xin)(xin)鋼(gang)(gang)(gang)板(ban)(ban)(ban)等。但目(mu)前常用(yong)(yong)(yong)的(de)(de)(de)仍為(wei)熱浸(jin)鍍(du)(du)(du)鋅(xin)(xin)板(ban)(ban)(ban)。 鍍(du)(du)(du)鋅(xin)(xin)鋼(gang)(gang)(gang)板(ban)(ban)(ban)按(an)用(yong)(yong)(yong)途又(you)可分為(wei)一(yi)般用(yong)(yong)(yong)、屋(wu)頂用(yong)(yong)(yong)、建筑外側板(ban)(ban)(ban)用(yong)(yong)(yong)、結構用(yong)(yong)(yong)、瓦(wa)壟板(ban)(ban)(ban)用(yong)(yong)(yong)、拉伸用(yong)(yong)(yong)和深(shen)沖用(yong)(yong)(yong)等鍍(du)(du)(du)鋅(xin)(xin)鋼(gang)(gang)(gang)板(ban)(ban)(ban)。
