鍍(du)鋅(xin)鋼(gang)(gang)(gang)板(ban)(ban)(ban)是為防止鋼(gang)(gang)(gang)板(ban)(ban)(ban)表(biao)面(mian)遭(zao)受腐蝕，延長其使用(yong)(yong)壽命，在鋼(gang)(gang)(gang)板(ban)(ban)(ban)表(biao)面(mian)涂(tu)以一層金(jin)(jin)(jin)屬鋅(xin)，這(zhe)種涂(tu)鋅(xin)的(de)(de)(de)(de)薄(bo)鋼(gang)(gang)(gang)板(ban)(ban)(ban)稱為鍍(du)鋅(xin)板(ban)(ban)(ban)。鋼(gang)(gang)(gang)板(ban)(ban)(ban)也是用(yong)(yong)熱(re)浸(jin)(jin)法(fa)制(zhi)(zhi)造，但(dan)在出槽(cao)(cao)后，立即(ji)(ji)(ji)把它加(jia)熱(re)到500℃左右，使其生成鋅(xin)和(he)鐵的(de)(de)(de)(de)合(he)金(jin)(jin)(jin)被膜。這(zhe)種鍍(du)鋅(xin)卷(juan)具有(you)(you)良好的(de)(de)(de)(de)涂(tu)料的(de)(de)(de)(de)密著性(xing)和(he)焊接(jie)性(xing)。合(he)金(jin)(jin)(jin)化鍍(du)鋅(xin)鋼(gang)(gang)(gang)板(ban)(ban)(ban)。這(zhe)種鋼(gang)(gang)(gang)板(ban)(ban)(ban)也是用(yong)(yong)熱(re)浸(jin)(jin)法(fa)制(zhi)(zhi)造，但(dan)在出槽(cao)(cao)后，立即(ji)(ji)(ji)把它加(jia)熱(re)到500℃左右，使其生成鋅(xin)和(he)鐵的(de)(de)(de)(de)合(he)金(jin)(jin)(jin)被膜。這(zhe)種鍍(du)鋅(xin)板(ban)(ban)(ban)具有(you)(you)良好的(de)(de)(de)(de)涂(tu)料的(de)(de)(de)(de)密著性(xing)和(he)焊接(jie)性(xing)。熱(re)浸(jin)(jin)鍍(du)鋅(xin)鋼(gang)(gang)(gang)板(ban)(ban)(ban)。將薄(bo)鋼(gang)(gang)(gang)板(ban)(ban)(ban)浸(jin)(jin)入熔解的(de)(de)(de)(de)鋅(xin)槽(cao)(cao)中，使其表(biao)面(mian)粘(zhan)附(fu)一層鋅(xin)的(de)(de)(de)(de)薄(bo)鋼(gang)(gang)(gang)板(ban)(ban)(ban)。目(mu)前主要采用(yong)(yong)連續(xu)(xu)鍍(du)鋅(xin)工藝生產，即(ji)(ji)(ji)把成卷(juan)的(de)(de)(de)(de)鋼(gang)(gang)(gang)板(ban)(ban)(ban)連續(xu)(xu)浸(jin)(jin)在熔解有(you)(you)鋅(xin)的(de)(de)(de)(de)鍍(du)槽(cao)(cao)中制(zhi)(zhi)成鍍(du)鋅(xin)鋼(gang)(gang)(gang)板(ban)(ban)(ban)。合(he)金(jin)(jin)(jin)、復合(he)鍍(du)鋅(xin)鋼(gang)(gang)(gang)板(ban)(ban)(ban)。它是用(yong)(yong)鋅(xin)和(he)其他金(jin)(jin)(jin)屬如鉛、鋅(xin)制(zhi)(zhi)成合(he)金(jin)(jin)(jin)乃至復合(he)鍍(du)成的(de)(de)(de)(de)鋼(gang)(gang)(gang)板(ban)(ban)(ban)。這(zhe)種鋼(gang)(gang)(gang)板(ban)(ban)(ban)既具有(you)(you)防銹(xiu)性(xing)能，又有(you)(you)良好的(de)(de)(de)(de)涂(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。樓承板批發輕型樓(lou)承板是近十(shi)年(nian)來發(fa)展(zhan)較快(kuai)的領域，在(zai)采用輕型樓(lou)承板占非(fei)住(zhu)宅建筑投資的50%以上。這種結構工業化(hua)、商(shang)品化(hua)程度高(gao)，施工快(kuai)，綜合效(xiao)益高(gao)，市場需求量很(hen)大，已引起結構設計人員認識。樓(lou)承板的研究(jiu)開發(fa)已在(zai)各地試點，是輕鋼發(fa)展(zhan)的一個重要方向(xiang)，目前已經有(you)多種的低層(ceng)、多層(ceng)和(he)高(gao)層(ceng)的設計方案和(he)實(shi)例。

重慶樓承板(ban)(ban)的(de)鍍(du)(du)(du)鋅(xin)(xin)(xin)(xin)量(liang)(liang)沒有一個具體的(de)標準，制作壓(ya)(ya)型(xing)鋼(gang)(gang)(gang)(gang)板(ban)(ban)的(de)冷軋鋼(gang)(gang)(gang)(gang)卷須(xu)連續熱浸鍍(du)(du)(du)鋅(xin)(xin)(xin)(xin)（或鍍(du)(du)(du)鋁(lv)鋅(xin)(xin)(xin)(xin)），鍍(du)(du)(du)（鋁(lv)）鋅(xin)(xin)(xin)(xin)量(liang)(liang)視設計要求而定。樓承板(ban)(ban)用壓(ya)(ya)型(xing)鋼(gang)(gang)(gang)(gang)板(ban)(ban)宜選擇熱浸鍍(du)(du)(du)鋅(xin)(xin)(xin)(xin)鋼(gang)(gang)(gang)(gang)板(ban)(ban)。不允許(xu)使用電鍍(du)(du)(du)鋅(xin)(xin)(xin)(xin)鋼(gang)(gang)(gang)(gang)板(ban)(ban)，電鍍(du)(du)(du)鋅(xin)(xin)(xin)(xin)鋼(gang)(gang)(gang)(gang)板(ban)(ban)僅在(zai)(zai)基材表面(mian)形成保護層，防(fang)腐能力(li)有限。目前市場(chang)上有鍍(du)(du)(du)鋅(xin)(xin)(xin)(xin)鋼(gang)(gang)(gang)(gang)板(ban)(ban)（鍍(du)(du)(du)層含鋁(lv)5%或55%），在(zai)(zai)酸性環境(jing)下的(de)防(fang)腐效(xiao)果由于(yu)熱浸鍍(du)(du)(du)鋅(xin)(xin)(xin)(xin)鋼(gang)(gang)(gang)(gang)板(ban)(ban)，但(dan)在(zai)(zai)混(hun)凝(ning)土的(de)堿(jian)性條(tiao)件下，鍍(du)(du)(du)鋁(lv)鋅(xin)(xin)(xin)(xin)的(de)防(fang)腐蝕性能低于(yu)熱浸鍍(du)(du)(du)鋅(xin)(xin)(xin)(xin)鋼(gang)(gang)(gang)(gang)板(ban)(ban)，且鋁(lv)會和混(hun)凝(ning)土發生反(fan)應(ying)，并降低混(hun)凝(ning)土與鋼(gang)(gang)(gang)(gang)板(ban)(ban)的(de)粘(zhan)結性能。因此參考國(guo)外規范，及國(guo)內(nei)外工(gong)程，行家壓(ya)(ya)型(xing)鋼(gang)(gang)(gang)(gang)板(ban)(ban)不建議(yi)使用鍍(du)(du)(du)鋁(lv)鋅(xin)(xin)(xin)(xin)鋼(gang)(gang)(gang)(gang)板(ban)(ban)。
