首先(xian)，在鋼結構樓層(ceng)板(ban)(ban)(ban)(ban)(ban)中要(yao)達(da)到耐火(huo)1.5小時(shi)，總(zong)的來說可以選擇開(kai)口(kou)(kou)(kou)板(ban)(ban)(ban)(ban)(ban)、縮(suo)口(kou)(kou)(kou)板(ban)(ban)(ban)(ban)(ban)、閉(bi)口(kou)(kou)(kou)板(ban)(ban)(ban)(ban)(ban)三大類。規范上混(hun)凝土要(yao)高于開(kai)口(kou)(kou)(kou)板(ban)(ban)(ban)(ban)(ban)肋頂之(zhi)上80mm，并且板(ban)(ban)(ban)(ban)(ban)底需(xu)(xu)配置板(ban)(ban)(ban)(ban)(ban)底受(shou)力筋。還有一種就(jiu)是再開(kai)口(kou)(kou)(kou)板(ban)(ban)(ban)(ban)(ban)底部刷防(fang)(fang)火(huo)涂料，涂料厚度大于等于15,這樣(yang)的話(hua)，只要(yao)達(da)到構造要(yao)求高于肋頂5公分就(jiu)可以了。而縮(suo)口(kou)(kou)(kou)板(ban)(ban)(ban)(ban)(ban)和閉(bi)口(kou)(kou)(kou)板(ban)(ban)(ban)(ban)(ban)，只需(xu)(xu)要(yao)總(zong)的樓板(ban)(ban)(ban)(ban)(ban)厚度大于等于110即可，但(dan)(dan)是縮(suo)口(kou)(kou)(kou)板(ban)(ban)(ban)(ban)(ban)雖然(ran)在防(fang)(fang)火(huo)方面(mian)比(bi)開(kai)口(kou)(kou)(kou)板(ban)(ban)(ban)(ban)(ban)要(yao)好。但(dan)(dan)是底部還是需(xu)(xu)要(yao)加板(ban)(ban)(ban)(ban)(ban)底受(shou)力筋，而閉(bi)口(kou)(kou)(kou)板(ban)(ban)(ban)(ban)(ban)則不需(xu)(xu)要(yao)。

鍍鋅廠家熱浸鍍鋅鋼板將薄鋼板浸入熔解的鋅槽中，使其表面粘附一層鋅的薄鋼板。目前主要采用連續鍍鋅工藝生產，即把成卷的鋼板連續浸在熔解有鋅的鍍槽中制成鍍鋅鋼板;合金化鍍鋅鋼板。宣威酒鋼鍍鋅這種(zhong)鋼板(ban)(ban)(ban)(ban)也是用熱(re)浸法制造，但在出槽后，立(li)即(ji)把它加熱(re)到500 ℃左右，使其(qi)生成鋅(xin)(xin)(xin)(xin)和鐵(tie)的(de)(de)合金被膜。這種(zhong)鍍鋅(xin)(xin)(xin)(xin)板(ban)(ban)(ban)(ban)具(ju)有(you)良好(hao)(hao)的(de)(de)涂料的(de)(de)密著(zhu)性(xing)(xing)和焊(han)(han)接性(xing)(xing);電鍍鋅(xin)(xin)(xin)(xin)鋼板(ban)(ban)(ban)(ban)。用電鍍法制造這種(zhong)鍍鋅(xin)(xin)(xin)(xin)鋼板(ban)(ban)(ban)(ban)具(ju)有(you)良好(hao)(hao)的(de)(de)加工(gong)性(xing)(xing)。但鍍層較薄，耐腐蝕(shi)性(xing)(xing)不(bu)如熱(re)浸法鍍鋅(xin)(xin)(xin)(xin)板(ban)(ban)(ban)(ban);單面(mian)(mian)(mian)(mian)鍍和雙面(mian)(mian)(mian)(mian)差鍍鋅(xin)(xin)(xin)(xin)鋼板(ban)(ban)(ban)(ban)。單面(mian)(mian)(mian)(mian)鍍鋅(xin)(xin)(xin)(xin)鋼板(ban)(ban)(ban)(ban)，即(ji)只在一面(mian)(mian)(mian)(mian)鍍鋅(xin)(xin)(xin)(xin)的(de)(de)產品。在焊(han)(han)接、涂裝(zhuang)、防銹(xiu)處(chu)理、加工(gong)等方(fang)面(mian)(mian)(mian)(mian)，具(ju)有(you)比(bi)雙面(mian)(mian)(mian)(mian)鍍鋅(xin)(xin)(xin)(xin)板(ban)(ban)(ban)(ban)好(hao)(hao)的(de)(de)適應(ying)性(xing)(xing)。

鍍(du)(du)(du)鋅(xin)(xin)(xin)(xin)鋼(gang)板(ban)(ban)按用(yong)(yong)途(tu)又可分(fen)為一般用(yong)(yong)、屋頂(ding)用(yong)(yong)、建(jian)筑(zhu)外側板(ban)(ban)用(yong)(yong)、結構用(yong)(yong)、瓦壟板(ban)(ban)用(yong)(yong)、拉伸用(yong)(yong)和深沖(chong)用(yong)(yong)等鍍(du)(du)(du)鋅(xin)(xin)(xin)(xin)鋼(gang)板(ban)(ban)。熱鍍(du)(du)(du)鋅(xin)(xin)(xin)(xin)板(ban)(ban)主要應用(yong)(yong)于建(jian)筑(zhu)外用(yong)(yong)，建(jian)筑(zhu)內用(yong)(yong)，民用(yong)(yong)，門窗，家(jia)(jia)具，機械，電子及(ji)家(jia)(jia)用(yong)(yong)電器等領域。也有機箱(xiang)用(yong)(yong)這個，不過熱鍍(du)(du)(du)鋅(xin)(xin)(xin)(xin)板(ban)(ban)不放(fang)輻射的(de)。空調，冰(bing)箱(xiang)，微波爐及(ji)其類似家(jia)(jia)電背面的(de)那(nei)個板(ban)(ban)就(jiu)是熱鍍(du)(du)(du)鋅(xin)(xin)(xin)(xin)板(ban)(ban)。鍍(du)(du)(du)鋅(xin)(xin)(xin)(xin)層通過鈍化處理(li)，可減少潮溫貯運條件下產生折銹(xiu)蝕(shi)(shi)(白銹(xiu)) 。但這種化學(xue)處理(li)的(de)防(fang)腐(fu)蝕(shi)(shi)性能(neng)是有限的(de)，而且，妨(fang)礙大多數涂(tu)料的(de)附(fu)著(zhu)性。這種處理(li)一般不用(yong)(yong)在鋅(xin)(xin)(xin)(xin)鐵(tie)合(he)金鍍(du)(du)(du)層，除光整表面外，作為常規，生產廠對其他類型的(de)鍍(du)(du)(du)鋅(xin)(xin)(xin)(xin)層均進(jin)行鈍化處理(li)。
