樓(lou)承(cheng)板(ban)(ban)(ban)(ban)適(shi)應主(zhu)體(ti)鋼結構快速施工(gong)的(de)(de)(de)(de)(de)要求，能夠在(zai)(zai)短時間內提供堅定(ding)的(de)(de)(de)(de)(de)作業平臺，并可(ke)采用(yong)多個樓(lou)層鋪設壓(ya)(ya)型鋼板(ban)(ban)(ban)(ban)，分層澆筑(zhu)混凝土(tu)板(ban)(ban)(ban)(ban)的(de)(de)(de)(de)(de)流水施工(gong)。在(zai)(zai)使用(yong)階段樓(lou)承(cheng)板(ban)(ban)(ban)(ban)作為混凝土(tu)樓(lou)板(ban)(ban)(ban)(ban)的(de)(de)(de)(de)(de)受拉鋼筋，也提高(gao)(gao)了樓(lou)板(ban)(ban)(ban)(ban)的(de)(de)(de)(de)(de)剛度，節省了鋼筋和混凝土(tu)的(de)(de)(de)(de)(de)用(yong)量。樓(lou)承(cheng)板(ban)(ban)(ban)(ban)上(shang)(shang)面(mian)可(ke)以鋪設保溫，隔(ge)音(yin)，隔(ge)熱，隔(ge)振等(deng)材料。樓(lou)面(mian)性(xing)能充分發揮鋼的(de)(de)(de)(de)(de)良好的(de)(de)(de)(de)(de)抗拉強(qiang)(qiang)度和延性(xing)及(ji)混凝土(tu)優(you)良的(de)(de)(de)(de)(de)抗壓(ya)(ya)強(qiang)(qiang)度和較(jiao)大的(de)(de)(de)(de)(de)剛度。壓(ya)(ya)型板(ban)(ban)(ban)(ban)表面(mian)壓(ya)(ya)紋使樓(lou)承(cheng)板(ban)(ban)(ban)(ban)與混凝土(tu)之間產生大的(de)(de)(de)(de)(de)結合力，使二(er)者形成整體(ti)，配(pei)以加勁肋(lei)，使樓(lou)承(cheng)板(ban)(ban)(ban)(ban)系(xi)統具(ju)有高(gao)(gao)強(qiang)(qiang)承(cheng)載力。在(zai)(zai)懸臂條(tiao)件下(xia)，樓(lou)承(cheng)板(ban)(ban)(ban)(ban)僅作為性(xing)模板(ban)(ban)(ban)(ban)。懸挑的(de)(de)(de)(de)(de)長度可(ke)根(gen)據樓(lou)承(cheng)板(ban)(ban)(ban)(ban)的(de)(de)(de)(de)(de)截面(mian)特(te)性(xing)來(lai)定(ding)。為了防止懸挑板(ban)(ban)(ban)(ban)的(de)(de)(de)(de)(de)開裂(lie)，需在(zai)(zai)支座處(chu)依結構工(gong)程師的(de)(de)(de)(de)(de)設計配(pei)上(shang)(shang)負筋。

鍍(du)鋅(xin)(xin)(xin)(xin)是(shi)一(yi)種經(jing)常采(cai)用(yong)的(de)經(jing)濟而(er)有(you)效的(de)防(fang)腐(fu)方法。鋅(xin)(xin)(xin)(xin)產(chan)量的(de)一(yi)半左右均(jun)用(yong)于此(ci)種工藝。鍍(du)鋅(xin)(xin)(xin)(xin)卷是(shi)為防(fang)止鋼板(ban)(ban)表(biao)(biao)面遭受腐(fu)蝕延長其使用(yong)壽命，在(zai)鋼板(ban)(ban)表(biao)(biao)面涂(tu)(tu)以(yi)一(yi)層金屬(shu)鋅(xin)(xin)(xin)(xin)，這種涂(tu)(tu)鋅(xin)(xin)(xin)(xin)的(de)鋼板(ban)(ban)稱為鍍(du)鋅(xin)(xin)(xin)(xin)卷。鍍(du)鋅(xin)(xin)(xin)(xin)卷主要用(yong)于建(jian)筑、家電、汽車、容器、交通及家業(ye)等(deng)(deng)領域。特別是(shi)鋼結構建(jian)筑、汽車制造(zao)、鋼板(ban)(ban)倉制造(zao)等(deng)(deng)行業(ye)。耐腐(fu)蝕強、表(biao)(biao)面質量好、得利于深(shen)加工、經(jing)濟實用(yong)等(deng)(deng)。有(you)關產(chan)品標(biao)準都(dou)列(lie)明鍍(du)鋅(xin)(xin)(xin)(xin)卷推薦(jian)的(de)標(biao)準厚(hou)(hou)度(du)(du)、長度(du)(du)和寬度(du)(du)及其允許偏(pian)差。鍍(du)鋅(xin)(xin)(xin)(xin)卷厚(hou)(hou)度(du)(du)偏(pian)差一(yi)般在(zai)0.05mm，長寬偏(pian)差一(yi)般在(zai)5mm ，板(ban)(ban)材的(de)厚(hou)(hou)度(du)(du)一(yi)般在(zai)0.2-3.2之(zhi)間 。

鍍(du)鋅(xin)鋼板按用(yong)(yong)途又可(ke)分為(wei)一般用(yong)(yong)、屋(wu)頂用(yong)(yong)、建(jian)筑(zhu)外(wai)側板用(yong)(yong)、結構用(yong)(yong)、瓦壟板用(yong)(yong)、拉伸用(yong)(yong)和深沖(chong)用(yong)(yong)等(deng)鍍(du)鋅(xin)鋼板。熱(re)鍍(du)鋅(xin)板主(zhu)要應用(yong)(yong)于建(jian)筑(zhu)外(wai)用(yong)(yong)，建(jian)筑(zhu)內(nei)用(yong)(yong)，民用(yong)(yong)，門(men)窗，家(jia)具(ju)，機(ji)械，電(dian)(dian)子及家(jia)用(yong)(yong)電(dian)(dian)器等(deng)領域(yu)。也有(you)機(ji)箱(xiang)(xiang)用(yong)(yong)這個(ge)(ge)，不過(guo)熱(re)鍍(du)鋅(xin)板不放(fang)輻射的(de)(de)。空調，冰(bing)箱(xiang)(xiang)，微波爐及其(qi)類(lei)似家(jia)電(dian)(dian)背面的(de)(de)那(nei)個(ge)(ge)板就是熱(re)鍍(du)鋅(xin)板。鍍(du)鋅(xin)層(ceng)通過(guo)鈍化處(chu)理，可(ke)減少(shao)潮(chao)溫貯運條(tiao)件下產生折銹蝕(shi)(白銹) 。但這種化學(xue)處(chu)理的(de)(de)防腐蝕(shi)性能是有(you)限的(de)(de)，而且，妨礙大多數涂(tu)料的(de)(de)附(fu)著(zhu)性。這種處(chu)理一般不用(yong)(yong)在鋅(xin)鐵合(he)金鍍(du)層(ceng)，除光整表面外(wai)，作(zuo)為(wei)常規，生產廠對其(qi)他類(lei)型的(de)(de)鍍(du)鋅(xin)層(ceng)均進行鈍化處(chu)理。

熱鍍(du)(du)(du)(du)(du)鋅(xin)(xin)(xin)(xin)板(ban)(ban)和(he)電(dian)(dian)鍍(du)(du)(du)(du)(du)鋅(xin)(xin)(xin)(xin)板(ban)(ban)在(zai)鍍(du)(du)(du)(du)(du)鋅(xin)(xin)(xin)(xin)量上有(you)很大(da)的(de)差(cha)別(bie)，就像山東彩涂卷）。熱鍍(du)(du)(du)(du)(du)鋅(xin)(xin)(xin)(xin)的(de)鍍(du)(du)(du)(du)(du)鋅(xin)(xin)(xin)(xin)量不(bu)可(ke)(ke)能太小，一(yi)(yi)般(ban)較小為(wei)雙(shuang)面50～60g／m2，較大(da)可(ke)(ke)達(da)600g／m2。電(dian)(dian)鍍(du)(du)(du)(du)(du)鋅(xin)(xin)(xin)(xin)板(ban)(ban)的(de)鍍(du)(du)(du)(du)(du)鋅(xin)(xin)(xin)(xin)層可(ke)(ke)以很薄(bo)，較小達(da)15g／m2，但要(yao)求(qiu)鍍(du)(du)(du)(du)(du)層較厚的(de)話則生(sheng)產線速(su)度很慢，不(bu)適應現代化(hua)機組的(de)工(gong)藝特點，一(yi)(yi)般(ban)較大(da)為(wei)lO0g／m2左右。正(zheng)(zheng)因為(wei)如此，電(dian)(dian)鍍(du)(du)(du)(du)(du)鋅(xin)(xin)(xin)(xin)板(ban)(ban)的(de)生(sheng)產受到(dao)很大(da)的(de)限制(zhi)。工(gong)一(yi)(yi)般(ban)電(dian)(dian)鍍(du)(du)(du)(du)(du)鋅(xin)(xin)(xin)(xin)比較多(duo)，適用(yong)于(yu)小部件；熱鍍(du)(du)(du)(du)(du)鋅(xin)(xin)(xin)(xin)一(yi)(yi)般(ban)用(yong)于(yu)電(dian)(dian)力設備和(he)構件，適用(yong)于(yu)大(da)的(de)部件和(he)設備。當然他們的(de)價(jia)格也相對便宜一(yi)(yi)些。建設部已正(zheng)(zheng)式下文，淘汰技術(shu)落后的(de)冷鍍(du)(du)(du)(du)(du)鋅(xin)(xin)(xin)(xin)管，不(bu)準用(yong)冷鍍(du)(du)(du)(du)(du)鋅(xin)(xin)(xin)(xin)管作水、煤(mei)氣(qi)管。

C型鋼廠家熱鍍鋅卷板價格行業統計數據顯示，十一月國內粗鋼日均產量為兩百零九萬噸，環比下降3.3%，創出今年以來水平，但是當前減產受到季節性因素支撐，市場對數據有效性提出質疑。大渡口C型鋼鍍鋅(xin)卷工(gong)業(ye)品而言，近期(qi)陸(lu)續公布的(de)重要數據中性偏多(duo)。但值得注意(yi)的(de)是(shi)，同年十一月熱鍍鋅(xin)卷板(ban)價格工(gong)業(ye)增加值和(he)投資增速放(fang)緩，進一步印證了國內(nei)總(zong)需(xu)求乏(fa)力，工(gong)業(ye)復蘇形勢不容樂觀(guan)。加上(shang)未來經濟結構調整等(deng)因素(su)，工(gong)業(ye)品價格反彈(dan)高度將(jiang)有(you)(you)限。傳統需(xu)求淡(dan)季(ji)效應還在持續不斷地發酵，冬(dong)儲效果不佳。雖然數據顯(xian)示供(gong)應壓力開(kai)始減輕，但是(shi)目前處于鋼鐵(tie)需(xu)求淡(dan)季(ji)，市場成(cheng)交萎縮，下游采購遲遲未能(neng)有(you)(you)效跟(gen)進，市場信心不足，鍍鋅(xin)鋼板(ban)貿易商囤貨現象也(ye)不明(ming)顯(xian)。
