鍍(du)(du)(du)鋅(xin)(xin)(xin)鋼(gang)(gang)(gang)(gang)板(ban)(ban)是(shi)為防止鋼(gang)(gang)(gang)(gang)板(ban)(ban)表(biao)(biao)面遭受腐蝕，延長其(qi)(qi)使用(yong)(yong)壽(shou)命，在(zai)鋼(gang)(gang)(gang)(gang)板(ban)(ban)表(biao)(biao)面涂(tu)(tu)以一層金(jin)(jin)(jin)屬(shu)鋅(xin)(xin)(xin)，這種涂(tu)(tu)鋅(xin)(xin)(xin)的(de)(de)薄鋼(gang)(gang)(gang)(gang)板(ban)(ban)稱為鍍(du)(du)(du)鋅(xin)(xin)(xin)板(ban)(ban)。鋼(gang)(gang)(gang)(gang)板(ban)(ban)也(ye)是(shi)用(yong)(yong)熱浸(jin)(jin)法制(zhi)(zhi)造，但(dan)在(zai)出(chu)槽(cao)后，立即把(ba)它(ta)加熱到500℃左右，使其(qi)(qi)生(sheng)成(cheng)鋅(xin)(xin)(xin)和鐵的(de)(de)合(he)(he)(he)金(jin)(jin)(jin)被膜。這種鍍(du)(du)(du)鋅(xin)(xin)(xin)卷(juan)具(ju)(ju)有良(liang)好的(de)(de)涂(tu)(tu)料(liao)的(de)(de)密著性(xing)和焊接(jie)性(xing)。合(he)(he)(he)金(jin)(jin)(jin)化鍍(du)(du)(du)鋅(xin)(xin)(xin)鋼(gang)(gang)(gang)(gang)板(ban)(ban)。這種鋼(gang)(gang)(gang)(gang)板(ban)(ban)也(ye)是(shi)用(yong)(yong)熱浸(jin)(jin)法制(zhi)(zhi)造，但(dan)在(zai)出(chu)槽(cao)后，立即把(ba)它(ta)加熱到500℃左右，使其(qi)(qi)生(sheng)成(cheng)鋅(xin)(xin)(xin)和鐵的(de)(de)合(he)(he)(he)金(jin)(jin)(jin)被膜。這種鍍(du)(du)(du)鋅(xin)(xin)(xin)板(ban)(ban)具(ju)(ju)有良(liang)好的(de)(de)涂(tu)(tu)料(liao)的(de)(de)密著性(xing)和焊接(jie)性(xing)。熱浸(jin)(jin)鍍(du)(du)(du)鋅(xin)(xin)(xin)鋼(gang)(gang)(gang)(gang)板(ban)(ban)。將薄鋼(gang)(gang)(gang)(gang)板(ban)(ban)浸(jin)(jin)入熔解(jie)的(de)(de)鋅(xin)(xin)(xin)槽(cao)中，使其(qi)(qi)表(biao)(biao)面粘附一層鋅(xin)(xin)(xin)的(de)(de)薄鋼(gang)(gang)(gang)(gang)板(ban)(ban)。目前主要采用(yong)(yong)連續鍍(du)(du)(du)鋅(xin)(xin)(xin)工藝生(sheng)產，即把(ba)成(cheng)卷(juan)的(de)(de)鋼(gang)(gang)(gang)(gang)板(ban)(ban)連續浸(jin)(jin)在(zai)熔解(jie)有鋅(xin)(xin)(xin)的(de)(de)鍍(du)(du)(du)槽(cao)中制(zhi)(zhi)成(cheng)鍍(du)(du)(du)鋅(xin)(xin)(xin)鋼(gang)(gang)(gang)(gang)板(ban)(ban)。合(he)(he)(he)金(jin)(jin)(jin)、復合(he)(he)(he)鍍(du)(du)(du)鋅(xin)(xin)(xin)鋼(gang)(gang)(gang)(gang)板(ban)(ban)。它(ta)是(shi)用(yong)(yong)鋅(xin)(xin)(xin)和其(qi)(qi)他金(jin)(jin)(jin)屬(shu)如鉛、鋅(xin)(xin)(xin)制(zhi)(zhi)成(cheng)合(he)(he)(he)金(jin)(jin)(jin)乃至(zhi)復合(he)(he)(he)鍍(du)(du)(du)成(cheng)的(de)(de)鋼(gang)(gang)(gang)(gang)板(ban)(ban)。這種鋼(gang)(gang)(gang)(gang)板(ban)(ban)既具(ju)(ju)有防銹性(xing)能，又有良(liang)好的(de)(de)涂(tu)(tu)裝(zhuang)性(xing)能。

我國建筑業中，噪聲污染問題久為人們所詬病。廣西鍍鋅帶鋼輕型樓承板的應用使得土建建筑物局面被打破，集環境破壞及污染少、材料回收和利用率高、符合可持續發展要求等眾多優點于一身的樓承板建筑應運而生，逐步被人們所接受。鍍鋅帶鋼廠家輕型樓承(cheng)(cheng)(cheng)板(ban)是近(jin)十年來發(fa)展較快(kuai)的(de)領域，在采用輕型樓承(cheng)(cheng)(cheng)板(ban)占(zhan)非住宅建筑投資的(de)50%以上。這種(zhong)結構工業化、商品化程度高，施工快(kuai)，綜合效益高，市(shi)場需求量很大，已(yi)(yi)引起(qi)結構設計(ji)人員認識。樓承(cheng)(cheng)(cheng)板(ban)的(de)研究開發(fa)已(yi)(yi)在各地試點(dian)，是輕鋼發(fa)展的(de)一個重要方向，目前已(yi)(yi)經有多種(zhong)的(de)低層、多層和高層的(de)設計(ji)方案和實(shi)例。

鍍鋅(xin)(xin)鋼(gang)板按(an)用(yong)(yong)(yong)(yong)(yong)途又可(ke)分為一般用(yong)(yong)(yong)(yong)(yong)、屋(wu)頂用(yong)(yong)(yong)(yong)(yong)、建筑外側板用(yong)(yong)(yong)(yong)(yong)、結構用(yong)(yong)(yong)(yong)(yong)、瓦壟板用(yong)(yong)(yong)(yong)(yong)、拉伸用(yong)(yong)(yong)(yong)(yong)和深(shen)沖用(yong)(yong)(yong)(yong)(yong)等(deng)(deng)鍍鋅(xin)(xin)鋼(gang)板。熱(re)鍍鋅(xin)(xin)板主要應用(yong)(yong)(yong)(yong)(yong)于(yu)建筑外用(yong)(yong)(yong)(yong)(yong)，建筑內用(yong)(yong)(yong)(yong)(yong)，民用(yong)(yong)(yong)(yong)(yong)，門窗(chuang)，家(jia)具，機械，電子(zi)及家(jia)用(yong)(yong)(yong)(yong)(yong)電器(qi)等(deng)(deng)領(ling)域。也有(you)機箱(xiang)(xiang)用(yong)(yong)(yong)(yong)(yong)這個，不過(guo)熱(re)鍍鋅(xin)(xin)板不放輻射(she)的。空調，冰箱(xiang)(xiang)，微波爐及其(qi)類似家(jia)電背面的那個板就(jiu)是熱(re)鍍鋅(xin)(xin)板。鍍鋅(xin)(xin)層通過(guo)鈍(dun)化(hua)處理(li)(li)，可(ke)減少潮溫貯運(yun)條件下產(chan)生折(zhe)銹蝕(白(bai)銹) 。但這種化(hua)學處理(li)(li)的防(fang)腐(fu)蝕性(xing)能是有(you)限的，而且，妨礙大多(duo)數涂料的附著性(xing)。這種處理(li)(li)一般不用(yong)(yong)(yong)(yong)(yong)在(zai)鋅(xin)(xin)鐵合金鍍層，除光(guang)整表(biao)面外，作為常(chang)規，生產(chan)廠對其(qi)他類型的鍍鋅(xin)(xin)層均進行鈍(dun)化(hua)處理(li)(li)。
