鍍(du)(du)(du)鋅(xin)(xin)(xin)鋼(gang)(gang)(gang)板(ban)(ban)(ban)(ban)是(shi)為(wei)防止鋼(gang)(gang)(gang)板(ban)(ban)(ban)(ban)表(biao)面遭受腐蝕，延長其(qi)(qi)使(shi)(shi)用壽命，在(zai)(zai)鋼(gang)(gang)(gang)板(ban)(ban)(ban)(ban)表(biao)面涂(tu)以一層(ceng)金(jin)屬鋅(xin)(xin)(xin)，這種(zhong)(zhong)涂(tu)鋅(xin)(xin)(xin)的(de)(de)薄(bo)鋼(gang)(gang)(gang)板(ban)(ban)(ban)(ban)稱為(wei)鍍(du)(du)(du)鋅(xin)(xin)(xin)板(ban)(ban)(ban)(ban)。鋼(gang)(gang)(gang)板(ban)(ban)(ban)(ban)也(ye)是(shi)用熱(re)浸(jin)法制(zhi)造(zao)，但在(zai)(zai)出(chu)槽后，立即把(ba)它(ta)加熱(re)到(dao)500℃左右，使(shi)(shi)其(qi)(qi)生(sheng)成(cheng)(cheng)(cheng)鋅(xin)(xin)(xin)和(he)鐵的(de)(de)合金(jin)被膜。這種(zhong)(zhong)鍍(du)(du)(du)鋅(xin)(xin)(xin)卷具(ju)有良好的(de)(de)涂(tu)料的(de)(de)密(mi)著性和(he)焊接(jie)性。合金(jin)化鍍(du)(du)(du)鋅(xin)(xin)(xin)鋼(gang)(gang)(gang)板(ban)(ban)(ban)(ban)。這種(zhong)(zhong)鋼(gang)(gang)(gang)板(ban)(ban)(ban)(ban)也(ye)是(shi)用熱(re)浸(jin)法制(zhi)造(zao)，但在(zai)(zai)出(chu)槽后，立即把(ba)它(ta)加熱(re)到(dao)500℃左右，使(shi)(shi)其(qi)(qi)生(sheng)成(cheng)(cheng)(cheng)鋅(xin)(xin)(xin)和(he)鐵的(de)(de)合金(jin)被膜。這種(zhong)(zhong)鍍(du)(du)(du)鋅(xin)(xin)(xin)板(ban)(ban)(ban)(ban)具(ju)有良好的(de)(de)涂(tu)料的(de)(de)密(mi)著性和(he)焊接(jie)性。熱(re)浸(jin)鍍(du)(du)(du)鋅(xin)(xin)(xin)鋼(gang)(gang)(gang)板(ban)(ban)(ban)(ban)。將薄(bo)鋼(gang)(gang)(gang)板(ban)(ban)(ban)(ban)浸(jin)入熔解(jie)的(de)(de)鋅(xin)(xin)(xin)槽中，使(shi)(shi)其(qi)(qi)表(biao)面粘附一層(ceng)鋅(xin)(xin)(xin)的(de)(de)薄(bo)鋼(gang)(gang)(gang)板(ban)(ban)(ban)(ban)。目前主要采用連續(xu)鍍(du)(du)(du)鋅(xin)(xin)(xin)工(gong)藝生(sheng)產，即把(ba)成(cheng)(cheng)(cheng)卷的(de)(de)鋼(gang)(gang)(gang)板(ban)(ban)(ban)(ban)連續(xu)浸(jin)在(zai)(zai)熔解(jie)有鋅(xin)(xin)(xin)的(de)(de)鍍(du)(du)(du)槽中制(zhi)成(cheng)(cheng)(cheng)鍍(du)(du)(du)鋅(xin)(xin)(xin)鋼(gang)(gang)(gang)板(ban)(ban)(ban)(ban)。合金(jin)、復(fu)合鍍(du)(du)(du)鋅(xin)(xin)(xin)鋼(gang)(gang)(gang)板(ban)(ban)(ban)(ban)。它(ta)是(shi)用鋅(xin)(xin)(xin)和(he)其(qi)(qi)他金(jin)屬如(ru)鉛、鋅(xin)(xin)(xin)制(zhi)成(cheng)(cheng)(cheng)合金(jin)乃至復(fu)合鍍(du)(du)(du)成(cheng)(cheng)(cheng)的(de)(de)鋼(gang)(gang)(gang)板(ban)(ban)(ban)(ban)。這種(zhong)(zhong)鋼(gang)(gang)(gang)板(ban)(ban)(ban)(ban)既具(ju)有防銹性能(neng)，又有良好的(de)(de)涂(tu)裝性能(neng)。

我國建筑業中，噪聲污染問題久為人們所詬病。廣安樓承板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。樓承板批發輕(qing)型樓承(cheng)板(ban)是近十年來發展較快的(de)領域(yu)，在(zai)采用輕(qing)型樓承(cheng)板(ban)占非住宅建筑投資的(de)50%以上。這(zhe)種結構工業化、商品化程度高(gao)(gao)，施工快，綜合效(xiao)益高(gao)(gao)，市(shi)場需求量很大(da)，已(yi)引起結構設(she)(she)計人員認識(shi)。樓承(cheng)板(ban)的(de)研究開發已(yi)在(zai)各(ge)地試點，是輕(qing)鋼發展的(de)一個重(zhong)要(yao)方向，目(mu)前已(yi)經有多種的(de)低層(ceng)、多層(ceng)和(he)高(gao)(gao)層(ceng)的(de)設(she)(she)計方案和(he)實例(li)。
