熱(re)(re)浸鍍(du)(du)鋅鋼(gang)(gang)(gang)板(ban)(ban)將薄(bo)鋼(gang)(gang)(gang)板(ban)(ban)浸入熔(rong)解(jie)的(de)鋅槽(cao)中(zhong)，使其表面(mian)粘附一層鋅的(de)薄(bo)鋼(gang)(gang)(gang)板(ban)(ban)。目前主要(yao)采用(yong)連(lian)(lian)續(xu)鍍(du)(du)鋅工藝生產(chan)，即(ji)(ji)把(ba)成卷的(de)鋼(gang)(gang)(gang)板(ban)(ban)連(lian)(lian)續(xu)浸在(zai)熔(rong)解(jie)有鋅的(de)鍍(du)(du)槽(cao)中(zhong)制(zhi)成鍍(du)(du)鋅鋼(gang)(gang)(gang)板(ban)(ban);合金化鍍(du)(du)鋅鋼(gang)(gang)(gang)板(ban)(ban)。這(zhe)種(zhong)鋼(gang)(gang)(gang)板(ban)(ban)也是用(yong)熱(re)(re)浸法(fa)制(zhi)造，但在(zai)出槽(cao)后，立即(ji)(ji)把(ba)它加(jia)(jia)(jia)熱(re)(re)到500 ℃左右(you)，使其生成鋅和鐵的(de)合金被膜。這(zhe)種(zhong)鍍(du)(du)鋅板(ban)(ban)具(ju)有良(liang)(liang)好的(de)涂(tu)料的(de)密(mi)著性(xing)(xing)和焊(han)接性(xing)(xing);電鍍(du)(du)鋅鋼(gang)(gang)(gang)板(ban)(ban)。用(yong)電鍍(du)(du)法(fa)制(zhi)造這(zhe)種(zhong)鍍(du)(du)鋅鋼(gang)(gang)(gang)板(ban)(ban)具(ju)有良(liang)(liang)好的(de)加(jia)(jia)(jia)工性(xing)(xing)。但鍍(du)(du)層較薄(bo)，耐腐(fu)蝕性(xing)(xing)不如熱(re)(re)浸法(fa)鍍(du)(du)鋅板(ban)(ban);單(dan)面(mian)鍍(du)(du)和雙面(mian)差鍍(du)(du)鋅鋼(gang)(gang)(gang)板(ban)(ban)。單(dan)面(mian)鍍(du)(du)鋅鋼(gang)(gang)(gang)板(ban)(ban)，即(ji)(ji)只(zhi)在(zai)一面(mian)鍍(du)(du)鋅的(de)產(chan)品。在(zai)焊(han)接、涂(tu)裝、防銹(xiu)處理、加(jia)(jia)(jia)工等(deng)方面(mian)，具(ju)有比雙面(mian)鍍(du)(du)鋅板(ban)(ban)好的(de)適應(ying)性(xing)(xing)。

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。陜西彩涂卷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。彩涂卷批發而(er)縮(suo)(suo)口(kou)板(ban)和閉口(kou)板(ban)，只(zhi)需(xu)要總的樓板(ban)厚度大于等于110即(ji)可(ke)，但是縮(suo)(suo)口(kou)板(ban)雖然在(zai)防火方面比開口(kou)板(ban)要好(hao)。但是底部還是需(xu)要加板(ban)底受力(li)筋，而(er)閉口(kou)板(ban)則不需(xu)要。

用(yong)(yong)(yong)電鍍(du)(du)(du)(du)(du)法制(zhi)造這種鍍(du)(du)(du)(du)(du)鋅(xin)(xin)(xin)(xin)(xin)(xin)鋼(gang)板(ban)(ban)(ban)(ban)具(ju)有(you)良好的(de)(de)加工性(xing)(xing)。但鍍(du)(du)(du)(du)(du)層(ceng)較(jiao)薄，耐(nai)腐蝕性(xing)(xing)不如(ru)熱(re)浸法鍍(du)(du)(du)(du)(du)鋅(xin)(xin)(xin)(xin)(xin)(xin)板(ban)(ban)(ban)(ban)；單(dan)(dan)面(mian)(mian)鍍(du)(du)(du)(du)(du)和(he)雙面(mian)(mian)差(cha)鍍(du)(du)(du)(du)(du)鋅(xin)(xin)(xin)(xin)(xin)(xin)鋼(gang)板(ban)(ban)(ban)(ban)。單(dan)(dan)面(mian)(mian)鍍(du)(du)(du)(du)(du)鋅(xin)(xin)(xin)(xin)(xin)(xin)鋼(gang)板(ban)(ban)(ban)(ban)，即只在(zai)一(yi)面(mian)(mian)鍍(du)(du)(du)(du)(du)鋅(xin)(xin)(xin)(xin)(xin)(xin)的(de)(de)產品。在(zai)焊接、涂(tu)裝、防銹處(chu)理、加工等方面(mian)(mian)，具(ju)有(you)比(bi)雙面(mian)(mian)鍍(du)(du)(du)(du)(du)鋅(xin)(xin)(xin)(xin)(xin)(xin)板(ban)(ban)(ban)(ban)好的(de)(de)適應性(xing)(xing)。為克服單(dan)(dan)面(mian)(mian)未涂(tu)鋅(xin)(xin)(xin)(xin)(xin)(xin)的(de)(de)缺點(dian)，又有(you)一(yi)種在(zai)另面(mian)(mian)涂(tu)以薄層(ceng)鋅(xin)(xin)(xin)(xin)(xin)(xin)的(de)(de)鍍(du)(du)(du)(du)(du)鋅(xin)(xin)(xin)(xin)(xin)(xin)板(ban)(ban)(ban)(ban)，即雙面(mian)(mian)差(cha)鍍(du)(du)(du)(du)(du)鋅(xin)(xin)(xin)(xin)(xin)(xin)板(ban)(ban)(ban)(ban)；合(he)(he)金、復(fu)合(he)(he)鍍(du)(du)(du)(du)(du)鋅(xin)(xin)(xin)(xin)(xin)(xin)鋼(gang)板(ban)(ban)(ban)(ban)。它是用(yong)(yong)(yong)鋅(xin)(xin)(xin)(xin)(xin)(xin)和(he)其(qi)他金屬如(ru)鉛、鋅(xin)(xin)(xin)(xin)(xin)(xin)制(zhi)成(cheng)合(he)(he)金乃至復(fu)合(he)(he)鍍(du)(du)(du)(du)(du)成(cheng)的(de)(de)鋼(gang)板(ban)(ban)(ban)(ban)。這種鋼(gang)板(ban)(ban)(ban)(ban)既具(ju)有(you)防銹性(xing)(xing)能，又有(you)良好的(de)(de)涂(tu)裝性(xing)(xing)能。 除上述五種外(wai)，還有(you)彩色鍍(du)(du)(du)(du)(du)鋅(xin)(xin)(xin)(xin)(xin)(xin)鋼(gang)板(ban)(ban)(ban)(ban)、印花涂(tu)裝鍍(du)(du)(du)(du)(du)鋅(xin)(xin)(xin)(xin)(xin)(xin)鋼(gang)板(ban)(ban)(ban)(ban)、聚(ju)氯乙烯疊層(ceng)鍍(du)(du)(du)(du)(du)鋅(xin)(xin)(xin)(xin)(xin)(xin)鋼(gang)板(ban)(ban)(ban)(ban)等。但目前常用(yong)(yong)(yong)的(de)(de)仍為熱(re)浸鍍(du)(du)(du)(du)(du)鋅(xin)(xin)(xin)(xin)(xin)(xin)板(ban)(ban)(ban)(ban)。 鍍(du)(du)(du)(du)(du)鋅(xin)(xin)(xin)(xin)(xin)(xin)鋼(gang)板(ban)(ban)(ban)(ban)按用(yong)(yong)(yong)途又可分為一(yi)般(ban)用(yong)(yong)(yong)、屋頂用(yong)(yong)(yong)、建(jian)筑外(wai)側板(ban)(ban)(ban)(ban)用(yong)(yong)(yong)、結構用(yong)(yong)(yong)、瓦(wa)壟板(ban)(ban)(ban)(ban)用(yong)(yong)(yong)、拉伸(shen)用(yong)(yong)(yong)和(he)深沖(chong)用(yong)(yong)(yong)等鍍(du)(du)(du)(du)(du)鋅(xin)(xin)(xin)(xin)(xin)(xin)鋼(gang)板(ban)(ban)(ban)(ban)。

隨著鋼(gang)結(jie)構(gou)(gou)在(zai)(zai)建筑(zhu)材料中的(de)(de)(de)興(xing)起(qi)，越(yue)來越(yue)多的(de)(de)(de)人選擇使用(yong)鋼(gang)結(jie)構(gou)(gou)樓(lou)(lou)(lou)(lou)承(cheng)板(ban)(ban)(ban)了，鋼(gang)結(jie)構(gou)(gou)構(gou)(gou)件工廠產(chan)業化生產(chan)大大縮(suo)短了工程工期，而樓(lou)(lou)(lou)(lou)板(ban)(ban)(ban)的(de)(de)(de)施工方法卻(que)成為(wei)影(ying)響(xiang)工期的(de)(de)(de)重要因(yin)素(su)。采(cai)用(yong)那一代樓(lou)(lou)(lou)(lou)承(cheng)板(ban)(ban)(ban)對于樓(lou)(lou)(lou)(lou)板(ban)(ban)(ban)的(de)(de)(de)耐(nai)火性(xing)能也有(you)區別。樓(lou)(lou)(lou)(lou)承(cheng)板(ban)(ban)(ban)的(de)(de)(de)厚(hou)度(du)(du)(du)(du)一般都是(shi)(shi)按保險起(qi)見設計的(de)(de)(de)比(bi)較(jiao)厚(hou)，正常(chang)情況(kuang)下鋼(gang)梁之(zhi)間的(de)(de)(de)跨度(du)(du)(du)(du)在(zai)(zai)2m以(yi)內樓(lou)(lou)(lou)(lou)承(cheng)板(ban)(ban)(ban)厚(hou)度(du)(du)(du)(du)在(zai)(zai)0.75-0.8mm就可以(yi)了，2-2.5m樓(lou)(lou)(lou)(lou)承(cheng)板(ban)(ban)(ban)厚(hou)度(du)(du)(du)(du)用(yong)0.8-1.0就可以(yi)了，跨度(du)(du)(du)(du)在(zai)(zai)3-4米樓(lou)(lou)(lou)(lou)承(cheng)板(ban)(ban)(ban)厚(hou)度(du)(du)(du)(du)用(yong)1.5mm，超(chao)過5m的(de)(de)(de)跨度(du)(du)(du)(du)是(shi)(shi)用(yong)臨(lin)時支撐，因(yin)素(su)就是(shi)(shi)混泥土澆筑(zhu)的(de)(de)(de)高度(du)(du)(du)(du)，混泥土澆筑(zhu)的(de)(de)(de)越(yue)高，樓(lou)(lou)(lou)(lou)承(cheng)板(ban)(ban)(ban)所(suo)需要的(de)(de)(de)厚(hou)度(du)(du)(du)(du)也就越(yue)厚(hou)，還有(you)一個大家(jia)容易忽略的(de)(de)(de)因(yin)素(su)就是(shi)(shi)螺(luo)釘(ding)的(de)(de)(de)好壞也是(shi)(shi)決定樓(lou)(lou)(lou)(lou)承(cheng)板(ban)(ban)(ban)厚(hou)度(du)(du)(du)(du)的(de)(de)(de)，螺(luo)釘(ding)越(yue)好樓(lou)(lou)(lou)(lou)承(cheng)板(ban)(ban)(ban)的(de)(de)(de)承(cheng)載力就越(yue)強。
