鍍(du)(du)(du)(du)鋅(xin)鋼(gang)(gang)(gang)板(ban)(ban)是為防止(zhi)鋼(gang)(gang)(gang)板(ban)(ban)表(biao)面(mian)遭受(shou)腐蝕(shi)，延長其(qi)使用壽命，在(zai)鋼(gang)(gang)(gang)板(ban)(ban)表(biao)面(mian)涂以一(yi)層金屬鋅(xin)，這(zhe)種涂鋅(xin)的薄(bo)鋼(gang)(gang)(gang)板(ban)(ban)稱為鍍(du)(du)(du)(du)鋅(xin)板(ban)(ban)。按生(sheng)產及加工(gong)(gong)方法可分為以下(xia)幾類(lei)：熱浸(jin)(jin)鍍(du)(du)(du)(du)鋅(xin)鋼(gang)(gang)(gang)板(ban)(ban)。將薄(bo)鋼(gang)(gang)(gang)板(ban)(ban)浸(jin)(jin)入熔 微商貨源解(jie)的鋅(xin)槽(cao)(cao)中，使其(qi)表(biao)面(mian)粘(zhan)附一(yi)層鋅(xin)的薄(bo)鋼(gang)(gang)(gang)板(ban)(ban)。目前主要采用連續鍍(du)(du)(du)(du)鋅(xin)工(gong)(gong)藝生(sheng)產，即把(ba)(ba)成(cheng)(cheng)卷的鋼(gang)(gang)(gang)板(ban)(ban)連續浸(jin)(jin)在(zai)熔解(jie)有(you)(you)鋅(xin)的鍍(du)(du)(du)(du)槽(cao)(cao)中制(zhi)(zhi)成(cheng)(cheng)鍍(du)(du)(du)(du)鋅(xin)鋼(gang)(gang)(gang)板(ban)(ban)；合金化鍍(du)(du)(du)(du)鋅(xin)鋼(gang)(gang)(gang)板(ban)(ban)。這(zhe)種鋼(gang)(gang)(gang)板(ban)(ban)也是用熱浸(jin)(jin)法制(zhi)(zhi)造(zao)，但(dan)在(zai)出槽(cao)(cao)后，立(li)即把(ba)(ba)它加熱到(dao)５００℃左右，使其(qi)生(sheng)成(cheng)(cheng)鋅(xin)和(he)(he)鐵的合金被膜。這(zhe)種鍍(du)(du)(du)(du)鋅(xin)板(ban)(ban)具(ju)有(you)(you)良好(hao)的涂料(liao)的密著性(xing)和(he)(he)焊(han)接性(xing)。

樓(lou)承(cheng)(cheng)板(ban)(ban)(ban)組合板(ban)(ban)(ban)是一種十分(fen)(fen)合理(li)的(de)(de)結(jie)構方式，它能(neng)(neng)夠按其各(ge)組成部件所處的(de)(de)方位和特色，充(chong)分(fen)(fen)發(fa)揮鋼材抗拉和混凝(ning)土抗壓功能(neng)(neng)好的(de)(de)長處，并(bing)具有杰(jie)出(chu)的(de)(de)抗震功能(neng)(neng)、施工功能(neng)(neng)。這種結(jie)構現(xian)在(zai)被廣泛(fan)運(yun)(yun)用(yong)于國(guo)內外修建中，但在(zai)國(guo)內大(da)都(dou)將樓(lou)承(cheng)(cheng)板(ban)(ban)(ban)當(dang)作(zuo)(zuo)模(mo)板(ban)(ban)(ban)運(yun)(yun)用(yong)，而沒有充(chong)分(fen)(fen)發(fa)揮樓(lou)承(cheng)(cheng)板(ban)(ban)(ban)的(de)(de)效果。 與一般(ban)鋼筋混凝(ning)土樓(lou)板(ban)(ban)(ban)比較，樓(lou)承(cheng)(cheng)板(ban)(ban)(ban)組合樓(lou)板(ban)(ban)(ban)具備(bei)以下長處：樓(lou)承(cheng)(cheng)板(ban)(ban)(ban)能(neng)(neng)夠作(zuo)(zuo)為現(xian)澆混凝(ning)土的(de)(de)模(mo)板(ban)(ban)(ban)。這樣就省掉了施工中裝置和撤除模(mo)板(ban)(ban)(ban)等(deng)工序(xu)，然后節約了時(shi)刻(ke)和勞動力(li);當(dang)樓(lou)承(cheng)(cheng)板(ban)(ban)(ban)裝置好今后將能(neng)(neng)夠作(zuo)(zuo)為施工平臺運(yun)(yun)用(yong)。
