鍍(du)(du)鋅(xin)鋼(gang)板(ban)(ban)(ban)(ban)是為(wei)防止鋼(gang)板(ban)(ban)(ban)(ban)表面遭受腐蝕(shi)，延(yan)長其(qi)(qi)使(shi)用(yong)壽命，在鋼(gang)板(ban)(ban)(ban)(ban)表面涂(tu)(tu)(tu)以一層金(jin)(jin)屬(shu)鋅(xin)，這(zhe)種涂(tu)(tu)(tu)鋅(xin)的(de)(de)薄(bo)鋼(gang)板(ban)(ban)(ban)(ban)稱為(wei)鍍(du)(du)鋅(xin)板(ban)(ban)(ban)(ban)。按生(sheng)產及加工(gong)方法可分為(wei)以下幾類：熱(re)浸(jin)鍍(du)(du)鋅(xin)鋼(gang)板(ban)(ban)(ban)(ban)。將薄(bo)鋼(gang)板(ban)(ban)(ban)(ban)浸(jin)入(ru)熔(rong) 微商貨源解(jie)的(de)(de)鋅(xin)槽(cao)中，使(shi)其(qi)(qi)表面粘附一層鋅(xin)的(de)(de)薄(bo)鋼(gang)板(ban)(ban)(ban)(ban)。目前主要采(cai)用(yong)連續(xu)鍍(du)(du)鋅(xin)工(gong)藝(yi)生(sheng)產，即把成(cheng)卷的(de)(de)鋼(gang)板(ban)(ban)(ban)(ban)連續(xu)浸(jin)在熔(rong)解(jie)有鋅(xin)的(de)(de)鍍(du)(du)槽(cao)中制(zhi)(zhi)成(cheng)鍍(du)(du)鋅(xin)鋼(gang)板(ban)(ban)(ban)(ban)；合(he)金(jin)(jin)化鍍(du)(du)鋅(xin)鋼(gang)板(ban)(ban)(ban)(ban)。這(zhe)種鋼(gang)板(ban)(ban)(ban)(ban)也是用(yong)熱(re)浸(jin)法制(zhi)(zhi)造(zao)，但在出槽(cao)后(hou)，立(li)即把它(ta)加熱(re)到５００℃左右，使(shi)其(qi)(qi)生(sheng)成(cheng)鋅(xin)和鐵的(de)(de)合(he)金(jin)(jin)被膜。這(zhe)種鍍(du)(du)鋅(xin)板(ban)(ban)(ban)(ban)具有良(liang)好的(de)(de)涂(tu)(tu)(tu)料的(de)(de)密著性和焊接性。

熱鍍鋅卷板價(jia)格(ge)行業(ye)(ye)統計數(shu)據(ju)顯示(shi)，十一月(yue)(yue)國內(nei)粗(cu)鋼日均產(chan)量為兩(liang)百零九萬(wan)噸，環比下降3.3%，創出今年以(yi)來水平(ping)，但(dan)是當前減產(chan)受(shou)到季節性因素支撐，市(shi)場(chang)對數(shu)據(ju)有(you)效(xiao)性提(ti)出質疑。鍍鋅卷工(gong)業(ye)(ye)品而言，近(jin)期陸(lu)續(xu)公(gong)布的(de)(de)重要(yao)數(shu)據(ju)中性偏多。但(dan)值得注意的(de)(de)是，同年十一月(yue)(yue)熱鍍鋅卷板價(jia)格(ge)工(gong)業(ye)(ye)增(zeng)加值和投資增(zeng)速放(fang)緩，進(jin)一步(bu)印證(zheng)了(le)國內(nei)總(zong)需求(qiu)乏力(li)，工(gong)業(ye)(ye)復蘇形(xing)勢不容樂觀。加上未來經濟結構調(diao)整(zheng)等因素，工(gong)業(ye)(ye)品價(jia)格(ge)反彈(dan)高度將有(you)限。傳統需求(qiu)淡季效(xiao)應還在持續(xu)不斷地發(fa)酵，冬儲效(xiao)果不佳。雖然數(shu)據(ju)顯示(shi)供應壓(ya)力(li)開始(shi)減輕，但(dan)是目前處于鋼鐵需求(qiu)淡季，市(shi)場(chang)成交萎(wei)縮，下游采購遲遲未能有(you)效(xiao)跟進(jin)，市(shi)場(chang)信心不足，鍍鋅鋼板貿易商囤貨現象也不明顯。

樓(lou)(lou)(lou)承(cheng)(cheng)板(ban)適應(ying)主體鋼結(jie)構快速施工(gong)的(de)(de)(de)要求(qiu)，能(neng)夠(gou)在短(duan)時間內提(ti)供堅定的(de)(de)(de)作(zuo)業(ye)平臺，并可(ke)采用多個樓(lou)(lou)(lou)層鋪(pu)設(she)壓(ya)(ya)型鋼板(ban)，分層澆筑(zhu)混(hun)(hun)凝土(tu)(tu)板(ban)的(de)(de)(de)流水施工(gong)。在使用階段樓(lou)(lou)(lou)承(cheng)(cheng)板(ban)作(zuo)為混(hun)(hun)凝土(tu)(tu)樓(lou)(lou)(lou)板(ban)的(de)(de)(de)受拉鋼筋(jin)，也提(ti)高了樓(lou)(lou)(lou)板(ban)的(de)(de)(de)剛度，節省(sheng)了鋼筋(jin)和混(hun)(hun)凝土(tu)(tu)的(de)(de)(de)用量。樓(lou)(lou)(lou)承(cheng)(cheng)板(ban)上面(mian)可(ke)以鋪(pu)設(she)保溫，隔(ge)音，隔(ge)熱，隔(ge)振等材(cai)料。樓(lou)(lou)(lou)面(mian)性(xing)(xing)能(neng)充分發(fa)揮鋼的(de)(de)(de)良(liang)好的(de)(de)(de)抗拉強(qiang)(qiang)度和延(yan)性(xing)(xing)及混(hun)(hun)凝土(tu)(tu)優良(liang)的(de)(de)(de)抗壓(ya)(ya)強(qiang)(qiang)度和較大的(de)(de)(de)剛度。壓(ya)(ya)型板(ban)表面(mian)壓(ya)(ya)紋使樓(lou)(lou)(lou)承(cheng)(cheng)板(ban)與(yu)混(hun)(hun)凝土(tu)(tu)之間產(chan)生大的(de)(de)(de)結(jie)合力，使二者(zhe)形成整體，配以加(jia)勁肋，使樓(lou)(lou)(lou)承(cheng)(cheng)板(ban)系統具有(you)高強(qiang)(qiang)承(cheng)(cheng)載力。在懸臂條(tiao)件下，樓(lou)(lou)(lou)承(cheng)(cheng)板(ban)僅作(zuo)為性(xing)(xing)模板(ban)。懸挑的(de)(de)(de)長(chang)度可(ke)根據樓(lou)(lou)(lou)承(cheng)(cheng)板(ban)的(de)(de)(de)截面(mian)特性(xing)(xing)來定。為了防止懸挑板(ban)的(de)(de)(de)開裂，需在支座處依結(jie)構工(gong)程師(shi)的(de)(de)(de)設(she)計配上負筋(jin)。

鍍(du)鋅(xin)(xin)鋼(gang)板(ban)(ban)(ban)按用(yong)(yong)(yong)途又可分為一般用(yong)(yong)(yong)、屋(wu)頂(ding)用(yong)(yong)(yong)、建筑(zhu)外側板(ban)(ban)(ban)用(yong)(yong)(yong)、結構(gou)用(yong)(yong)(yong)、瓦壟板(ban)(ban)(ban)用(yong)(yong)(yong)、拉伸用(yong)(yong)(yong)和深(shen)沖用(yong)(yong)(yong)等鍍(du)鋅(xin)(xin)鋼(gang)板(ban)(ban)(ban)。熱(re)鍍(du)鋅(xin)(xin)板(ban)(ban)(ban)主(zhu)要應用(yong)(yong)(yong)于建筑(zhu)外用(yong)(yong)(yong)，建筑(zhu)內用(yong)(yong)(yong)，民(min)用(yong)(yong)(yong)，門窗，家具(ju)，機(ji)(ji)械，電子及家用(yong)(yong)(yong)電器等領域。也(ye)有(you)機(ji)(ji)箱(xiang)(xiang)用(yong)(yong)(yong)這個，不(bu)過(guo)熱(re)鍍(du)鋅(xin)(xin)板(ban)(ban)(ban)不(bu)放輻射的(de)。空(kong)調(diao)，冰箱(xiang)(xiang)，微波爐及其類似家電背面(mian)的(de)那(nei)個板(ban)(ban)(ban)就是熱(re)鍍(du)鋅(xin)(xin)板(ban)(ban)(ban)。鍍(du)鋅(xin)(xin)層(ceng)通過(guo)鈍化處(chu)理(li)，可減少潮溫貯運條(tiao)件(jian)下產生折銹(xiu)蝕(shi)(白(bai)銹(xiu)) 。但這種(zhong)化學處(chu)理(li)的(de)防腐蝕(shi)性能是有(you)限的(de)，而且，妨礙大(da)多數涂(tu)料的(de)附(fu)著(zhu)性。這種(zhong)處(chu)理(li)一般不(bu)用(yong)(yong)(yong)在(zai)鋅(xin)(xin)鐵合(he)金鍍(du)層(ceng)，除光(guang)整表(biao)面(mian)外，作(zuo)為常(chang)規，生產廠對其他類型(xing)的(de)鍍(du)鋅(xin)(xin)層(ceng)均進行(xing)鈍化處(chu)理(li)。

樓(lou)(lou)承(cheng)(cheng)板(ban)(ban)(ban)能(neng)夠滿足快速施(shi)工(gong)(gong)的(de)(de)需求，可(ke)以(yi)在短時(shi)間內搭建起牢固(gu)的(de)(de)作業(ye)平臺，而(er)且(qie)還能(neng)把多個樓(lou)(lou)承(cheng)(cheng)板(ban)(ban)(ban)層鋪設壓型(xing)鋼板(ban)(ban)(ban)，分層澆(jiao)筑混(hun)(hun)凝(ning)(ning)土板(ban)(ban)(ban)的(de)(de)流水施(shi)工(gong)(gong)作業(ye)。可(ke)以(yi)作為混(hun)(hun)凝(ning)(ning)土樓(lou)(lou)板(ban)(ban)(ban)的(de)(de)受拉鋼筋(jin)，可(ke)以(yi)使(shi)(shi)樓(lou)(lou)板(ban)(ban)(ban)的(de)(de)剛(gang)度增強(qiang)，而(er)且(qie)使(shi)(shi)得鋼筋(jin)和(he)混(hun)(hun)凝(ning)(ning)土的(de)(de)用量明顯減少(shao)。壓型(xing)板(ban)(ban)(ban)表(biao)面壓紋(wen)使(shi)(shi)樓(lou)(lou)承(cheng)(cheng)板(ban)(ban)(ban)與(yu)混(hun)(hun)凝(ning)(ning)土之(zhi)間產生大的(de)(de)結(jie)合(he)(he)力(li)，使(shi)(shi)二者形(xing)成整體，再配合(he)(he)上(shang)加勁(jing)肋，使(shi)(shi)得有高(gao)強(qiang)承(cheng)(cheng)載力(li)。還可(ke)以(yi)作為性模板(ban)(ban)(ban)，懸(xuan)挑(tiao)的(de)(de)長度可(ke)根據樓(lou)(lou)承(cheng)(cheng)板(ban)(ban)(ban)的(de)(de)截面特性來定(ding)。為了防止懸(xuan)挑(tiao)板(ban)(ban)(ban)的(de)(de)開裂，需在支(zhi)座處依結(jie)構(gou)工(gong)(gong)程師的(de)(de)設計配上(shang)負(fu)筋(jin)。而(er)且(qie)都是經(jing)過(guo)固(gu)定(ding)滅火(huo)系統(tong)及(ji)耐(nai)火(huo)構(gou)件質量檢測中心的(de)(de)耐(nai)火(huo)檢測，具有防火(huo)的(de)(de)特性。
