湖北白鐵重慶樓承板的鍍鋅量沒有一個具體的標準，制作壓型鋼板的冷軋鋼卷須連續熱浸鍍鋅（或鍍鋁鋅），鍍（鋁）鋅量視設計要求而定。白鐵廠家樓承(cheng)板(ban)(ban)(ban)(ban)(ban)用壓型(xing)鋼(gang)板(ban)(ban)(ban)(ban)(ban)宜(yi)選(xuan)擇(ze)熱浸(jin)鍍(du)鋅(xin)(xin)(xin)鋼(gang)板(ban)(ban)(ban)(ban)(ban)。不(bu)允(yun)許使用電(dian)鍍(du)鋅(xin)(xin)(xin)鋼(gang)板(ban)(ban)(ban)(ban)(ban)，電(dian)鍍(du)鋅(xin)(xin)(xin)鋼(gang)板(ban)(ban)(ban)(ban)(ban)僅在(zai)基材表面形成保護層(ceng)，防(fang)腐能(neng)力有限。目前市場上有鍍(du)鋅(xin)(xin)(xin)鋼(gang)板(ban)(ban)(ban)(ban)(ban)（鍍(du)層(ceng)含鋁5%或55%），在(zai)酸性(xing)環境下的(de)(de)防(fang)腐效果(guo)由(you)于(yu)(yu)熱浸(jin)鍍(du)鋅(xin)(xin)(xin)鋼(gang)板(ban)(ban)(ban)(ban)(ban)，但在(zai)混(hun)凝(ning)土的(de)(de)堿性(xing)條(tiao)件下，鍍(du)鋁鋅(xin)(xin)(xin)的(de)(de)防(fang)腐蝕性(xing)能(neng)低(di)于(yu)(yu)熱浸(jin)鍍(du)鋅(xin)(xin)(xin)鋼(gang)板(ban)(ban)(ban)(ban)(ban)，且鋁會和混(hun)凝(ning)土發生反應，并降低(di)混(hun)凝(ning)土與鋼(gang)板(ban)(ban)(ban)(ban)(ban)的(de)(de)粘結性(xing)能(neng)。因(yin)此參(can)考國外規范，及(ji)國內外工程，行家壓型(xing)鋼(gang)板(ban)(ban)(ban)(ban)(ban)不(bu)建議(yi)使用鍍(du)鋁鋅(xin)(xin)(xin)鋼(gang)板(ban)(ban)(ban)(ban)(ban)。

重慶鍍(du)(du)鋅(xin)(xin)(xin)(xin)板(ban)(ban)(ban)(ban)(ban)按(an)生(sheng)產(chan)及加工方法可分為以下幾類： 熱浸鍍(du)(du)鋅(xin)(xin)(xin)(xin)鋼(gang)板(ban)(ban)(ban)(ban)(ban)。將薄鋼(gang)板(ban)(ban)(ban)(ban)(ban)浸入(ru)熔(rong)解的(de)鋅(xin)(xin)(xin)(xin)槽(cao)(cao)中(zhong)，使其表(biao)面粘附(fu)一層鋅(xin)(xin)(xin)(xin)的(de)薄鋼(gang)板(ban)(ban)(ban)(ban)(ban)。目前主要采用(yong)連(lian)續鍍(du)(du)鋅(xin)(xin)(xin)(xin)工藝生(sheng)產(chan)，即(ji)把成(cheng)(cheng)卷的(de)鋼(gang)板(ban)(ban)(ban)(ban)(ban)連(lian)續浸在(zai)熔(rong)解有(you)鋅(xin)(xin)(xin)(xin)的(de)鍍(du)(du)槽(cao)(cao)中(zhong)制成(cheng)(cheng)鍍(du)(du)鋅(xin)(xin)(xin)(xin)鋼(gang)板(ban)(ban)(ban)(ban)(ban)； 合(he)金化鍍(du)(du)鋅(xin)(xin)(xin)(xin)鋼(gang)板(ban)(ban)(ban)(ban)(ban)。為克服單面未涂鋅(xin)(xin)(xin)(xin)的(de)缺(que)點(dian)，又有(you)一種在(zai)另面涂以薄層鋅(xin)(xin)(xin)(xin)的(de)鍍(du)(du)鋅(xin)(xin)(xin)(xin)板(ban)(ban)(ban)(ban)(ban)，即(ji)雙面差鍍(du)(du)鋅(xin)(xin)(xin)(xin)板(ban)(ban)(ban)(ban)(ban)；合(he)金、復(fu)合(he)鍍(du)(du)鋅(xin)(xin)(xin)(xin)鋼(gang)板(ban)(ban)(ban)(ban)(ban)。它是用(yong)鋅(xin)(xin)(xin)(xin)和其他金屬(shu)如鉛、鋅(xin)(xin)(xin)(xin)制成(cheng)(cheng)合(he)金乃至復(fu)合(he)鍍(du)(du)成(cheng)(cheng)的(de)鋼(gang)板(ban)(ban)(ban)(ban)(ban)。這種鋼(gang)板(ban)(ban)(ban)(ban)(ban)既(ji)具有(you)防銹性能，又有(you)良好的(de)涂裝性能。

重慶樓承板(ban)由于(yu)(yu)在(zai)(zai)高(gao)(gao)層建(jian)筑和大(da)(da)跨(kua)度高(gao)(gao)聳結構方面的(de)(de)(de)(de)優(you)越性(xing)，使其在(zai)(zai)非居住建(jian)筑領域(yu)得到了廣(guang)泛的(de)(de)(de)(de)應用(yong)(yong)。用(yong)(yong)環保鋼(gang)(gang)筋(jin)(jin)桁(heng)架(jia)(jia)樓承板(ban)建(jian)筑的(de)(de)(de)(de)房(fang)子比傳統房(fang)屋(wu)的(de)(de)(de)(de)重量要輕一(yi)倍，運用(yong)(yong)面積(ji)也進步百分之(zhi)(zhi)五(wu)左右，這(zhe)個(ge)(ge)就是(shi)它(ta)一(yi)大(da)(da)優(you)點自(zi)重輕強(qiang)度高(gao)(gao)。依據不完(wan)整的(de)(de)(de)(de)統計，我國在(zai)(zai)發作(zuo)地(di)震時鋼(gang)(gang)筋(jin)(jin)桁(heng)架(jia)(jia)樓承板(ban)建(jian)筑的(de)(de)(de)(de)倒(dao)塌幾率簡直(zhi)是(shi)零，所(suo)以它(ta)的(de)(de)(de)(de)抗(kang)震性(xing)能好也是(shi)它(ta)的(de)(de)(de)(de)優(you)點之(zhi)(zhi)一(yi)，由于(yu)(yu)鋼(gang)(gang)筋(jin)(jin)桁(heng)架(jia)(jia)樓承板(ban)建(jian)筑的(de)(de)(de)(de)一(yi)些構件(jian)、墻板(ban)等有關的(de)(de)(de)(de)建(jian)材都是(shi)在(zai)(zai)工(gong)廠(chang)里(li)完(wan)成的(de)(de)(de)(de)，所(suo)以就減(jian)少了現場(chang)施工(gong)的(de)(de)(de)(de)工(gong)作(zuo)量，縮短了施工(gong)的(de)(de)(de)(de)工(gong)作(zuo)時間，很(hen)契合產業化的(de)(de)(de)(de)請(qing)求(qiu)，這(zhe)個(ge)(ge)是(shi)它(ta)的(de)(de)(de)(de)優(you)勢，第三個(ge)(ge)就是(shi)它(ta)的(de)(de)(de)(de)可回收應用(yong)(yong)了，它(ta)能夠隨意的(de)(de)(de)(de)撤除(chu)和建(jian)造，關于(yu)(yu)環境不形成污染，還節(jie)約了資源。
