崇州鍍鋅帶鋼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。鍍鋅帶鋼廠家樓承板(ban)(ban)(ban)用壓型鋼板(ban)(ban)(ban)宜選擇熱浸鍍(du)鋅(xin)(xin)(xin)(xin)鋼板(ban)(ban)(ban)。不允許使用電鍍(du)鋅(xin)(xin)(xin)(xin)鋼板(ban)(ban)(ban)，電鍍(du)鋅(xin)(xin)(xin)(xin)鋼板(ban)(ban)(ban)僅在(zai)基材表面形(xing)成保護層，防腐(fu)能力有(you)(you)限。目前市場上(shang)有(you)(you)鍍(du)鋅(xin)(xin)(xin)(xin)鋼板(ban)(ban)(ban)（鍍(du)層含鋁5%或55%），在(zai)酸性環境下的(de)防腐(fu)效(xiao)果(guo)由于熱浸鍍(du)鋅(xin)(xin)(xin)(xin)鋼板(ban)(ban)(ban)，但在(zai)混凝(ning)土的(de)堿(jian)性條(tiao)件下，鍍(du)鋁鋅(xin)(xin)(xin)(xin)的(de)防腐(fu)蝕性能低于熱浸鍍(du)鋅(xin)(xin)(xin)(xin)鋼板(ban)(ban)(ban)，且鋁會(hui)和混凝(ning)土發生(sheng)反(fan)應，并(bing)降低混凝(ning)土與鋼板(ban)(ban)(ban)的(de)粘結性能。因此參考(kao)國外規范，及國內外工程，行家(jia)壓型鋼板(ban)(ban)(ban)不建(jian)議使用鍍(du)鋁鋅(xin)(xin)(xin)(xin)鋼板(ban)(ban)(ban)。

隨著鋼(gang)結構在(zai)建筑(zhu)材料中的(de)(de)(de)(de)(de)(de)(de)(de)興起(qi)，越來越多的(de)(de)(de)(de)(de)(de)(de)(de)人選擇使(shi)用(yong)鋼(gang)結構樓(lou)(lou)(lou)(lou)承(cheng)板(ban)(ban)了，鋼(gang)結構構件工(gong)(gong)廠產(chan)業化生產(chan)大大縮短(duan)了工(gong)(gong)程工(gong)(gong)期，而樓(lou)(lou)(lou)(lou)板(ban)(ban)的(de)(de)(de)(de)(de)(de)(de)(de)施工(gong)(gong)方法卻成(cheng)為影響工(gong)(gong)期的(de)(de)(de)(de)(de)(de)(de)(de)重要因(yin)素。采用(yong)那一代樓(lou)(lou)(lou)(lou)承(cheng)板(ban)(ban)對于樓(lou)(lou)(lou)(lou)板(ban)(ban)的(de)(de)(de)(de)(de)(de)(de)(de)耐火性能(neng)也有區別。樓(lou)(lou)(lou)(lou)承(cheng)板(ban)(ban)的(de)(de)(de)(de)(de)(de)(de)(de)厚度(du)一般都是按保(bao)險起(qi)見設計的(de)(de)(de)(de)(de)(de)(de)(de)比較厚，正常情況下鋼(gang)梁之(zhi)間的(de)(de)(de)(de)(de)(de)(de)(de)跨度(du)在(zai)2m以內樓(lou)(lou)(lou)(lou)承(cheng)板(ban)(ban)厚度(du)在(zai)0.75-0.8mm就(jiu)(jiu)(jiu)可以了，2-2.5m樓(lou)(lou)(lou)(lou)承(cheng)板(ban)(ban)厚度(du)用(yong)0.8-1.0就(jiu)(jiu)(jiu)可以了，跨度(du)在(zai)3-4米樓(lou)(lou)(lou)(lou)承(cheng)板(ban)(ban)厚度(du)用(yong)1.5mm，超過5m的(de)(de)(de)(de)(de)(de)(de)(de)跨度(du)是用(yong)臨時支撐，因(yin)素就(jiu)(jiu)(jiu)是混泥土(tu)澆(jiao)筑(zhu)的(de)(de)(de)(de)(de)(de)(de)(de)高度(du)，混泥土(tu)澆(jiao)筑(zhu)的(de)(de)(de)(de)(de)(de)(de)(de)越高，樓(lou)(lou)(lou)(lou)承(cheng)板(ban)(ban)所需(xu)要的(de)(de)(de)(de)(de)(de)(de)(de)厚度(du)也就(jiu)(jiu)(jiu)越厚，還有一個大家(jia)容(rong)易忽略的(de)(de)(de)(de)(de)(de)(de)(de)因(yin)素就(jiu)(jiu)(jiu)是螺釘的(de)(de)(de)(de)(de)(de)(de)(de)好(hao)壞(huai)也是決定(ding)樓(lou)(lou)(lou)(lou)承(cheng)板(ban)(ban)厚度(du)的(de)(de)(de)(de)(de)(de)(de)(de)，螺釘越好(hao)樓(lou)(lou)(lou)(lou)承(cheng)板(ban)(ban)的(de)(de)(de)(de)(de)(de)(de)(de)承(cheng)載力就(jiu)(jiu)(jiu)越強。
