首先，在(zai)鋼結構樓(lou)層板(ban)(ban)(ban)中要(yao)達到耐火1.5小(xiao)時，總的(de)來說可(ke)以選(xuan)擇開口(kou)(kou)板(ban)(ban)(ban)、縮(suo)口(kou)(kou)板(ban)(ban)(ban)、閉(bi)口(kou)(kou)板(ban)(ban)(ban)三大類。規范上混凝(ning)土要(yao)高于(yu)(yu)(yu)開口(kou)(kou)板(ban)(ban)(ban)肋頂之上80mm，并且板(ban)(ban)(ban)底(di)(di)需(xu)(xu)配置板(ban)(ban)(ban)底(di)(di)受力(li)筋(jin)。還(huan)有(you)一種就是(shi)(shi)再(zai)開口(kou)(kou)板(ban)(ban)(ban)底(di)(di)部(bu)刷防(fang)火涂(tu)料，涂(tu)料厚度大于(yu)(yu)(yu)等(deng)于(yu)(yu)(yu)15,這樣的(de)話(hua)，只(zhi)要(yao)達到構造要(yao)求高于(yu)(yu)(yu)肋頂5公(gong)分就可(ke)以了。而(er)縮(suo)口(kou)(kou)板(ban)(ban)(ban)和閉(bi)口(kou)(kou)板(ban)(ban)(ban)，只(zhi)需(xu)(xu)要(yao)總的(de)樓(lou)板(ban)(ban)(ban)厚度大于(yu)(yu)(yu)等(deng)于(yu)(yu)(yu)110即可(ke)，但(dan)(dan)是(shi)(shi)縮(suo)口(kou)(kou)板(ban)(ban)(ban)雖然在(zai)防(fang)火方面比開口(kou)(kou)板(ban)(ban)(ban)要(yao)好。但(dan)(dan)是(shi)(shi)底(di)(di)部(bu)還(huan)是(shi)(shi)需(xu)(xu)要(yao)加板(ban)(ban)(ban)底(di)(di)受力(li)筋(jin)，而(er)閉(bi)口(kou)(kou)板(ban)(ban)(ban)則不需(xu)(xu)要(yao)。

由于我國鋅資源比較豐富，鍍鋅又是一種價廉、能防銹，又能裝飾的高性價比鍍種，因而在汽車、機械、電子、船舶、儀表、輕工等工業部門得到廣泛的應用。如機械零件、低壓電器、高壓開關、緊固連接件、鋼鐵結構件、建筑五金、農業機械、輕工產品等都離不開鍍鋅鈍化制品。彩涂板廠家鍍鋅板卷因此可分為熱軋鍍鋅板卷和冷軋熱鍍鋅板卷，它們主要用于建筑、家電、汽車、容器、交通及家業等領域。特別是鋼結構建筑、汽車制造、鋼板倉制造等行業。河北彩涂板 重慶(qing)鍍鋅卷特點主(zhu)要為：耐腐蝕(shi)強、表面(mian)質量(liang)好、得利于深加工、經濟實用等。
