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。鍍鋅帶鋼批發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。西安鍍鋅帶鋼 重慶鍍(du)鋅卷特點主(zhu)要為(wei)：耐腐蝕強、表面(mian)質量好、得利于深加工(gong)、經濟實用等。

從整體生(sheng)(sheng)(sheng)產(chan)方(fang)面來看(kan)，人(ren)們能(neng)(neng)夠(gou)意(yi)識(shi)到(dao)鍍鋅(xin)板在生(sheng)(sheng)(sheng)產(chan)過(guo)程中(zhong)應(ying)(ying)用范圍是(shi)很大的(de)(de)，而各位朋(peng)友也應(ying)(ying)該認(ren)(ren)識(shi)該種產(chan)品未(wei)來發展的(de)(de)情況(kuang)，只有(you)這樣(yang)才能(neng)(neng)夠(gou)對產(chan)品有(you)更(geng)(geng)為掌(zhang)握(wo)。所以(yi)(yi)希望生(sheng)(sheng)(sheng)活中(zhong)每一位朋(peng)友都能(neng)(neng)夠(gou)認(ren)(ren)知這部(bu)分(fen)的(de)(de)內容(rong)，這樣(yang)在每個部(bu)分(fen)才能(neng)(neng)夠(gou)獲取好的(de)(de)答案。鍍鋅(xin)板生(sheng)(sheng)(sheng)產(chan)方(fang)面國內存(cun)(cun)在著供應(ying)(ying)不(bu)足的(de)(de)問(wen)題，所以(yi)(yi)市場方(fang)面應(ying)(ying)該加(jia)(jia)強生(sheng)(sheng)(sheng)產(chan)，而在生(sheng)(sheng)(sheng)產(chan)技術方(fang)面的(de)(de)提升也是(shi)很重要(yao)的(de)(de)。只有(you)能(neng)(neng)夠(gou)以(yi)(yi)更(geng)(geng)加(jia)(jia)認(ren)(ren)真的(de)(de)態度掌(zhang)握(wo)這部(bu)分(fen)的(de)(de)內容(rong)，這樣(yang)整體生(sheng)(sheng)(sheng)產(chan)才能(neng)(neng)夠(gou)更(geng)(geng)加(jia)(jia)順(shun)利。自然進(jin)口也是(shi)很重要(yao)的(de)(de)一部(bu)分(fen)，不(bu)過(guo)進(jin)口產(chan)品在價格方(fang)面也存(cun)(cun)在著更(geng)(geng)高方(fang)面的(de)(de)問(wen)題，所以(yi)(yi)國內生(sheng)(sheng)(sheng)產(chan)加(jia)(jia)強是(shi)很重要(yao)的(de)(de)。

首先，在鋼結構樓(lou)層板(ban)(ban)(ban)(ban)(ban)(ban)中(zhong)要達到(dao)耐(nai)火(huo)1.5小(xiao)時，總的來說可以(yi)選擇開口(kou)板(ban)(ban)(ban)(ban)(ban)(ban)、縮(suo)口(kou)板(ban)(ban)(ban)(ban)(ban)(ban)、閉口(kou)板(ban)(ban)(ban)(ban)(ban)(ban)三大(da)類。規(gui)范上(shang)混凝土要高于(yu)(yu)(yu)開口(kou)板(ban)(ban)(ban)(ban)(ban)(ban)肋頂(ding)(ding)之上(shang)80mm，并且板(ban)(ban)(ban)(ban)(ban)(ban)底需配(pei)置板(ban)(ban)(ban)(ban)(ban)(ban)底受力(li)筋。還(huan)有一種就是(shi)再開口(kou)板(ban)(ban)(ban)(ban)(ban)(ban)底部刷(shua)防火(huo)涂(tu)料，涂(tu)料厚度大(da)于(yu)(yu)(yu)等于(yu)(yu)(yu)15,這樣(yang)的話，只要達到(dao)構造要求(qiu)高于(yu)(yu)(yu)肋頂(ding)(ding)5公分就可以(yi)了。而縮(suo)口(kou)板(ban)(ban)(ban)(ban)(ban)(ban)和閉口(kou)板(ban)(ban)(ban)(ban)(ban)(ban)，只需要總的樓(lou)板(ban)(ban)(ban)(ban)(ban)(ban)厚度大(da)于(yu)(yu)(yu)等于(yu)(yu)(yu)110即可，但是(shi)縮(suo)口(kou)板(ban)(ban)(ban)(ban)(ban)(ban)雖然在防火(huo)方面比開口(kou)板(ban)(ban)(ban)(ban)(ban)(ban)要好。但是(shi)底部還(huan)是(shi)需要加板(ban)(ban)(ban)(ban)(ban)(ban)底受力(li)筋，而閉口(kou)板(ban)(ban)(ban)(ban)(ban)(ban)則不需要。

熱鍍鋅(xin)(xin)(xin)卷板(ban)價格(ge)(ge)行業統(tong)計數(shu)據(ju)顯(xian)示，十一月國內(nei)粗鋼(gang)日均(jun)產量(liang)為(wei)兩百零九萬噸(dun)，環比下(xia)降3.3%，創出今年(nian)以來(lai)(lai)水平(ping)，但(dan)是當(dang)前減產受(shou)到季(ji)節性因(yin)素支撐，市(shi)場對數(shu)據(ju)有(you)效性提出質疑。鍍鋅(xin)(xin)(xin)卷工(gong)(gong)業品而言，近期陸續(xu)公(gong)布(bu)的(de)重要數(shu)據(ju)中性偏多。但(dan)值得注意的(de)是，同年(nian)十一月熱鍍鋅(xin)(xin)(xin)卷板(ban)價格(ge)(ge)工(gong)(gong)業增加(jia)值和投(tou)資增速放緩，進一步印證了(le)國內(nei)總需求(qiu)(qiu)乏(fa)力，工(gong)(gong)業復(fu)蘇(su)形勢(shi)不(bu)容樂觀。加(jia)上(shang)未來(lai)(lai)經濟結構調整(zheng)等因(yin)素，工(gong)(gong)業品價格(ge)(ge)反(fan)彈(dan)高度將有(you)限。傳(chuan)統(tong)需求(qiu)(qiu)淡季(ji)效應(ying)還在(zai)持(chi)續(xu)不(bu)斷地發酵，冬儲(chu)效果不(bu)佳。雖然數(shu)據(ju)顯(xian)示供應(ying)壓力開始減輕，但(dan)是目(mu)前處(chu)于鋼(gang)鐵需求(qiu)(qiu)淡季(ji)，市(shi)場成交萎縮(suo)，下(xia)游采購(gou)遲(chi)遲(chi)未能有(you)效跟進，市(shi)場信心(xin)不(bu)足，鍍鋅(xin)(xin)(xin)鋼(gang)板(ban)貿易商囤(dun)貨現象也不(bu)明(ming)顯(xian)。

重慶(qing)樓承(cheng)板(ban)(ban)的(de)鍍(du)(du)鋅(xin)(xin)量沒有一個具體的(de)標準，制作壓(ya)型鋼(gang)(gang)(gang)(gang)(gang)板(ban)(ban)的(de)冷軋鋼(gang)(gang)(gang)(gang)(gang)卷須連續(xu)熱浸鍍(du)(du)鋅(xin)(xin)（或(huo)鍍(du)(du)鋁(lv)(lv)(lv)鋅(xin)(xin)），鍍(du)(du)（鋁(lv)(lv)(lv)）鋅(xin)(xin)量視設計要求而定。樓承(cheng)板(ban)(ban)用壓(ya)型鋼(gang)(gang)(gang)(gang)(gang)板(ban)(ban)宜選擇熱浸鍍(du)(du)鋅(xin)(xin)鋼(gang)(gang)(gang)(gang)(gang)板(ban)(ban)。不(bu)允許使(shi)用電(dian)鍍(du)(du)鋅(xin)(xin)鋼(gang)(gang)(gang)(gang)(gang)板(ban)(ban)，電(dian)鍍(du)(du)鋅(xin)(xin)鋼(gang)(gang)(gang)(gang)(gang)板(ban)(ban)僅在(zai)(zai)基材表面形成保護層，防(fang)腐(fu)(fu)能(neng)力(li)有限。目前市場(chang)上有鍍(du)(du)鋅(xin)(xin)鋼(gang)(gang)(gang)(gang)(gang)板(ban)(ban)（鍍(du)(du)層含鋁(lv)(lv)(lv)5%或(huo)55%），在(zai)(zai)酸(suan)性環境下(xia)的(de)防(fang)腐(fu)(fu)效果由于(yu)熱浸鍍(du)(du)鋅(xin)(xin)鋼(gang)(gang)(gang)(gang)(gang)板(ban)(ban)，但在(zai)(zai)混(hun)凝(ning)(ning)土(tu)的(de)堿性條件下(xia)，鍍(du)(du)鋁(lv)(lv)(lv)鋅(xin)(xin)的(de)防(fang)腐(fu)(fu)蝕性能(neng)低(di)于(yu)熱浸鍍(du)(du)鋅(xin)(xin)鋼(gang)(gang)(gang)(gang)(gang)板(ban)(ban)，且(qie)鋁(lv)(lv)(lv)會和混(hun)凝(ning)(ning)土(tu)發生(sheng)反應，并降低(di)混(hun)凝(ning)(ning)土(tu)與鋼(gang)(gang)(gang)(gang)(gang)板(ban)(ban)的(de)粘結性能(neng)。因此參考國外規范(fan)，及國內(nei)外工程(cheng)，行家壓(ya)型鋼(gang)(gang)(gang)(gang)(gang)板(ban)(ban)不(bu)建議使(shi)用鍍(du)(du)鋁(lv)(lv)(lv)鋅(xin)(xin)鋼(gang)(gang)(gang)(gang)(gang)板(ban)(ban)。
