首先，在鋼結構(gou)樓層(ceng)板(ban)(ban)(ban)中要(yao)達到(dao)耐火(huo)1.5小時(shi)，總(zong)的(de)來說可(ke)以選擇開(kai)口(kou)板(ban)(ban)(ban)、縮口(kou)板(ban)(ban)(ban)、閉口(kou)板(ban)(ban)(ban)三大(da)類。規(gui)范(fan)上混(hun)凝土要(yao)高于(yu)(yu)開(kai)口(kou)板(ban)(ban)(ban)肋(lei)頂之上80mm，并且板(ban)(ban)(ban)底(di)(di)需配置板(ban)(ban)(ban)底(di)(di)受力筋。還有一種就(jiu)是(shi)再(zai)開(kai)口(kou)板(ban)(ban)(ban)底(di)(di)部(bu)刷防火(huo)涂料(liao)，涂料(liao)厚(hou)度大(da)于(yu)(yu)等于(yu)(yu)15,這樣的(de)話，只要(yao)達到(dao)構(gou)造要(yao)求高于(yu)(yu)肋(lei)頂5公分就(jiu)可(ke)以了。而縮口(kou)板(ban)(ban)(ban)和閉口(kou)板(ban)(ban)(ban)，只需要(yao)總(zong)的(de)樓板(ban)(ban)(ban)厚(hou)度大(da)于(yu)(yu)等于(yu)(yu)110即可(ke)，但(dan)是(shi)縮口(kou)板(ban)(ban)(ban)雖然在防火(huo)方(fang)面比開(kai)口(kou)板(ban)(ban)(ban)要(yao)好。但(dan)是(shi)底(di)(di)部(bu)還是(shi)需要(yao)加板(ban)(ban)(ban)底(di)(di)受力筋，而閉口(kou)板(ban)(ban)(ban)則不需要(yao)。

樓(lou)承板(ban)(ban)(ban)鍍(du)(du)鋅(xin)首要(yao)起(qi)到(dao)防(fang)(fang)腐的(de)效果，按標準(zhun)組(zu)(zu)合(he)樓(lou)板(ban)(ban)(ban)與(yu)非組(zu)(zu)合(he)樓(lou)板(ban)(ban)(ban)壓型鋼(gang)板(ban)(ban)(ban)應選(xuan)用熱(re)鍍(du)(du)鋅(xin)，不(bu)該選(xuan)用電鍍(du)(du)鋅(xin)鋼(gang)板(ban)(ban)(ban)，其雙面(mian)鍍(du)(du)鋅(xin)層總(zong)含(han)量要(yao)滿足在使(shi)(shi)用期間不(bu)致銹損的(de)要(yao)求(qiu)。當作為非組(zu)(zu)合(he)樓(lou)承板(ban)(ban)(ban)時(shi)(shi)，鍍(du)(du)鋅(xin)層含(han)量可(ke)選(xuan)用較(jiao)(jiao)低值(zhi)(zhi);當為組(zu)(zu)合(he)樓(lou)承板(ban)(ban)(ban)時(shi)(shi)，鍍(du)(du)鋅(xin)層含(han)量不(bu)該小于150g/m2。當為組(zu)(zu)合(he)樓(lou)板(ban)(ban)(ban)且使(shi)(shi)用環境條件較(jiao)(jiao)為惡劣時(shi)(shi)，鍍(du)(du)鋅(xin)層含(han)量應選(xuan)用上限(xian)值(zhi)(zhi)或更高(gao)值(zhi)(zhi)。更高(gao)的(de)鍍(du)(du)鋅(xin)要(yao)求(qiu)，如雙面(mian)鍍(du)(du)鋅(xin)量為300g/m2、350g/m2或鍍(du)(du)鋁鋅(xin)(5%鋁)275g/m2、300g/m2等(deng)，較(jiao)(jiao)高(gao)的(de)鍍(du)(du)層量使(shi)(shi)組(zu)(zu)合(he)樓(lou)板(ban)(ban)(ban)有更長耐久性，同等(deng)量的(de)鍍(du)(du)鋁鋅(xin)的(de)防(fang)(fang)銹蝕才能大約兩(liang)倍于一般熱(re)鍍(du)(du)鋅(xin)。鍍(du)(du)鋅(xin)量也(ye)不(bu)是越厚(hou)越好(hao)，當鍍(du)(du)鋅(xin)量較(jiao)(jiao)厚(hou)時(shi)(shi)，抗剪連接件栓釘的(de)焊接質(zhi)量就很難保證，焊接時(shi)(shi)，宜選(xuan)用局部除(chu)鋅(xin)處理(li)措施。

由于我國鋅(xin)(xin)資源(yuan)比(bi)較豐富，鍍鋅(xin)(xin)又是一種(zhong)價廉、能防銹，又能裝飾的高(gao)性價比(bi)鍍種(zhong)，因而在汽車(che)、機械、電(dian)子、船舶、儀表、輕(qing)工(gong)等(deng)工(gong)業(ye)(ye)(ye)(ye)部門得到廣(guang)泛(fan)的應用(yong)。如機械零件(jian)、低壓(ya)電(dian)器、高(gao)壓(ya)開關、緊固連(lian)接件(jian)、鋼鐵結構件(jian)、建筑(zhu)(zhu)五金、農(nong)業(ye)(ye)(ye)(ye)機械、輕(qing)工(gong)產(chan)品(pin)等(deng)都離不開鍍鋅(xin)(xin)鈍化制(zhi)品(pin)。鍍鋅(xin)(xin)板卷(juan)因此可(ke)分為熱軋鍍鋅(xin)(xin)板卷(juan)和(he)冷(leng)軋熱鍍鋅(xin)(xin)板卷(juan)，它(ta)們主(zhu)要用(yong)于建筑(zhu)(zhu)、家電(dian)、汽車(che)、容(rong)器、交(jiao)通及家業(ye)(ye)(ye)(ye)等(deng)領(ling)域。特別是鋼結構建筑(zhu)(zhu)、汽車(che)制(zhi)造(zao)、鋼板倉制(zhi)造(zao)等(deng)行(xing)業(ye)(ye)(ye)(ye)。 重慶鍍鋅(xin)(xin)卷(juan)特點主(zhu)要為：耐腐蝕強、表面質量好、得利于深加(jia)工(gong)、經濟實用(yong)等(deng)。

鍍鋁鋅板批發樓承板適應主體鋼結構快速施工的要求，能夠在短時間內提供堅定的作業平臺，并可采用多個樓層鋪設壓型鋼板，分層澆筑混凝土板的流水施工。萬源鍍鋁鋅板在(zai)使用(yong)階段樓(lou)承(cheng)(cheng)板(ban)(ban)(ban)作為混(hun)凝(ning)土樓(lou)板(ban)(ban)(ban)的(de)(de)受拉(la)鋼(gang)筋，也(ye)提(ti)高了樓(lou)板(ban)(ban)(ban)的(de)(de)剛度(du)，節(jie)省了鋼(gang)筋和(he)混(hun)凝(ning)土的(de)(de)用(yong)量。樓(lou)承(cheng)(cheng)板(ban)(ban)(ban)上面(mian)可(ke)以(yi)(yi)鋪(pu)設(she)保(bao)溫(wen)，隔音，隔熱(re)，隔振等材料。樓(lou)面(mian)性(xing)能充分發揮鋼(gang)的(de)(de)良(liang)好的(de)(de)抗拉(la)強度(du)和(he)延性(xing)及混(hun)凝(ning)土優良(liang)的(de)(de)抗壓強度(du)和(he)較大的(de)(de)剛度(du)。壓型板(ban)(ban)(ban)表面(mian)壓紋使樓(lou)承(cheng)(cheng)板(ban)(ban)(ban)與混(hun)凝(ning)土之間產生(sheng)大的(de)(de)結合力，使二者形成整(zheng)體，配(pei)以(yi)(yi)加勁肋，使樓(lou)承(cheng)(cheng)板(ban)(ban)(ban)系(xi)統具(ju)有高強承(cheng)(cheng)載力。在(zai)懸(xuan)(xuan)臂條件下，樓(lou)承(cheng)(cheng)板(ban)(ban)(ban)僅作為性(xing)模板(ban)(ban)(ban)。懸(xuan)(xuan)挑的(de)(de)長度(du)可(ke)根據樓(lou)承(cheng)(cheng)板(ban)(ban)(ban)的(de)(de)截面(mian)特性(xing)來(lai)定。為了防止懸(xuan)(xuan)挑板(ban)(ban)(ban)的(de)(de)開裂(lie)，需在(zai)支座處依結構工程師的(de)(de)設(she)計配(pei)上負筋。
