首先，在(zai)鋼結構樓層板(ban)(ban)(ban)(ban)中(zhong)要(yao)達(da)到耐火(huo)1.5小時，總的來說可以(yi)選擇開(kai)口板(ban)(ban)(ban)(ban)、縮口板(ban)(ban)(ban)(ban)、閉口板(ban)(ban)(ban)(ban)三大(da)類。規(gui)范上混(hun)凝土要(yao)高于(yu)開(kai)口板(ban)(ban)(ban)(ban)肋(lei)頂之上80mm，并且(qie)板(ban)(ban)(ban)(ban)底(di)(di)需配(pei)置板(ban)(ban)(ban)(ban)底(di)(di)受(shou)力(li)(li)筋。還有一種就是(shi)再開(kai)口板(ban)(ban)(ban)(ban)底(di)(di)部(bu)刷防(fang)火(huo)涂(tu)料，涂(tu)料厚度大(da)于(yu)等(deng)于(yu)15,這(zhe)樣(yang)的話，只(zhi)要(yao)達(da)到構造(zao)要(yao)求高于(yu)肋(lei)頂5公分(fen)就可以(yi)了(le)。而縮口板(ban)(ban)(ban)(ban)和(he)閉口板(ban)(ban)(ban)(ban)，只(zhi)需要(yao)總的樓板(ban)(ban)(ban)(ban)厚度大(da)于(yu)等(deng)于(yu)110即可，但(dan)是(shi)縮口板(ban)(ban)(ban)(ban)雖然在(zai)防(fang)火(huo)方面比開(kai)口板(ban)(ban)(ban)(ban)要(yao)好(hao)。但(dan)是(shi)底(di)(di)部(bu)還是(shi)需要(yao)加板(ban)(ban)(ban)(ban)底(di)(di)受(shou)力(li)(li)筋，而閉口板(ban)(ban)(ban)(ban)則(ze)不需要(yao)。

鍍(du)(du)鋅(xin)(xin)(xin)(xin)鋼板(ban)(ban)(ban)(ban)(ban)(ban)(ban)是(shi)為(wei)(wei)防止鋼板(ban)(ban)(ban)(ban)(ban)(ban)(ban)表(biao)面(mian)遭受腐蝕，延長其使(shi)用壽命(ming)，在鋼板(ban)(ban)(ban)(ban)(ban)(ban)(ban)表(biao)面(mian)涂以一層金屬鋅(xin)(xin)(xin)(xin)，這(zhe)種(zhong)涂鋅(xin)(xin)(xin)(xin)的(de)(de)薄(bo)(bo)鋼板(ban)(ban)(ban)(ban)(ban)(ban)(ban)稱(cheng)為(wei)(wei)鍍(du)(du)鋅(xin)(xin)(xin)(xin)板(ban)(ban)(ban)(ban)(ban)(ban)(ban)。按生產及加工(gong)方法(fa)可分(fen)為(wei)(wei)以下幾類：熱(re)浸(jin)鍍(du)(du)鋅(xin)(xin)(xin)(xin)鋼板(ban)(ban)(ban)(ban)(ban)(ban)(ban)。將薄(bo)(bo)鋼板(ban)(ban)(ban)(ban)(ban)(ban)(ban)浸(jin)入熔 微商貨源解(jie)的(de)(de)鋅(xin)(xin)(xin)(xin)槽中(zhong)(zhong)，使(shi)其表(biao)面(mian)粘附一層鋅(xin)(xin)(xin)(xin)的(de)(de)薄(bo)(bo)鋼板(ban)(ban)(ban)(ban)(ban)(ban)(ban)。目前主要采用連續鍍(du)(du)鋅(xin)(xin)(xin)(xin)工(gong)藝生產，即(ji)把成(cheng)卷(juan)的(de)(de)鋼板(ban)(ban)(ban)(ban)(ban)(ban)(ban)連續浸(jin)在熔解(jie)有(you)(you)鋅(xin)(xin)(xin)(xin)的(de)(de)鍍(du)(du)槽中(zhong)(zhong)制成(cheng)鍍(du)(du)鋅(xin)(xin)(xin)(xin)鋼板(ban)(ban)(ban)(ban)(ban)(ban)(ban)；合金化鍍(du)(du)鋅(xin)(xin)(xin)(xin)鋼板(ban)(ban)(ban)(ban)(ban)(ban)(ban)。這(zhe)種(zhong)鋼板(ban)(ban)(ban)(ban)(ban)(ban)(ban)也是(shi)用熱(re)浸(jin)法(fa)制造，但在出槽后(hou)，立即(ji)把它(ta)加熱(re)到５００℃左右，使(shi)其生成(cheng)鋅(xin)(xin)(xin)(xin)和(he)(he)鐵的(de)(de)合金被膜。這(zhe)種(zhong)鍍(du)(du)鋅(xin)(xin)(xin)(xin)板(ban)(ban)(ban)(ban)(ban)(ban)(ban)具有(you)(you)良好(hao)的(de)(de)涂料的(de)(de)密著性(xing)和(he)(he)焊接(jie)性(xing)。

攀華白鐵廠家樓承板能夠滿足快速施工的需求，可以在短時間內搭建起牢固的作業平臺，而且還能把多個樓承板層鋪設壓型鋼板，分層澆筑混凝土板的流水施工作業。可以作為混凝土樓板的受拉鋼筋，可以使樓板的剛度增強，而且使得鋼筋和混凝土的用量明顯減少。白鐵廠家壓(ya)型(xing)板表(biao)面壓(ya)紋使(shi)(shi)樓(lou)承板與混凝(ning)土(tu)之(zhi)間產生大的(de)結合力(li)，使(shi)(shi)二者形成整(zheng)體，再配合上加勁肋，使(shi)(shi)得有(you)高強承載力(li)。還可(ke)以作為性(xing)模板，懸挑(tiao)的(de)長度可(ke)根據樓(lou)承板的(de)截面特(te)性(xing)來定。為了防止懸挑(tiao)板的(de)開裂，需在支座處依結構(gou)工程師的(de)設計配上負筋。而且(qie)都是經(jing)過固(gu)定滅火系統及耐(nai)火構(gou)件質量檢(jian)(jian)測中心的(de)耐(nai)火檢(jian)(jian)測，具(ju)有(you)防火的(de)特(te)性(xing)。

鍍(du)鋅(xin)(xin)(xin)(xin)(xin)是一種經常采用的(de)(de)(de)(de)經濟(ji)(ji)而有效的(de)(de)(de)(de)防腐方法。鋅(xin)(xin)(xin)(xin)(xin)產量的(de)(de)(de)(de)一半左右(you)均(jun)用于此種工藝。鍍(du)鋅(xin)(xin)(xin)(xin)(xin)卷是為防止鋼(gang)板表面(mian)遭受腐蝕延長(chang)其(qi)使用壽(shou)命，在(zai)鋼(gang)板表面(mian)涂以(yi)一層金屬鋅(xin)(xin)(xin)(xin)(xin)，這(zhe)種涂鋅(xin)(xin)(xin)(xin)(xin)的(de)(de)(de)(de)鋼(gang)板稱為鍍(du)鋅(xin)(xin)(xin)(xin)(xin)卷。鍍(du)鋅(xin)(xin)(xin)(xin)(xin)卷主要用于建筑、家(jia)(jia)電、汽車(che)、容器(qi)、交(jiao)通(tong)及家(jia)(jia)業(ye)(ye)等領(ling)域。特(te)別(bie)是鋼(gang)結構建筑、汽車(che)制(zhi)造(zao)、鋼(gang)板倉制(zhi)造(zao)等行業(ye)(ye)。耐(nai)腐蝕強、表面(mian)質量好、得(de)利(li)于深加(jia)工、經濟(ji)(ji)實用等。有關產品標準都列明鍍(du)鋅(xin)(xin)(xin)(xin)(xin)卷推薦的(de)(de)(de)(de)標準厚度、長(chang)度和寬度及其(qi)允許(xu)偏差(cha)。鍍(du)鋅(xin)(xin)(xin)(xin)(xin)卷厚度偏差(cha)一般在(zai)0.05mm，長(chang)寬偏差(cha)一般在(zai)5mm ，板材的(de)(de)(de)(de)厚度一般在(zai)0.2-3.2之(zhi)間 。

彩鋼(gang)(gang)是指(zhi)彩涂鋼(gang)(gang)板(ban)，彩涂鋼(gang)(gang)板(ban)是一種(zhong)帶有(you)有(you)機涂層(ceng)的(de)(de)鋼(gang)(gang)板(ban)，傳統的(de)(de)涂層(ceng)分好(hao)幾類，氟碳涂層(ceng)的(de)(de)，幾乎可(ke)以(yi)防腐20年。一般從鋼(gang)(gang)廠以(yi)卷(juan)筒的(de)(de)形式分銷到各地。我(wo)們經(jing)常看到的(de)(de)彩鋼(gang)(gang)板(ban)是指(zhi)加(jia)工好(hao)的(de)(de)板(ban)材，厚(hou)度在50~100mm左右，它(ta)是由中(zhong)間(jian)(jian)的(de)(de)填料和(he)兩面的(de)(de)彩鋼(gang)(gang)板(ban)組成。其中(zhong)，彩板(ban)厚(hou)度有(you)0.4mm、0.5mm、0.6mm等不(bu)同的(de)(de)厚(hou)度,中(zhong)間(jian)(jian)層(ceng)可(ke)以(yi)是聚胺脂、巖綿或泡沫塑料等。由于有(you)專(zhuan)用型材，所以(yi)用彩鋼(gang)(gang)板(ban)構筑的(de)(de)廠房建造速度很(hen)快（如非典時(shi)的(de)(de)小湯山醫(yi)院），但強度低。
