熱(re)(re)鍍鋅卷(juan)板價(jia)格行業(ye)統計數(shu)據(ju)(ju)(ju)顯(xian)示，十一月國內(nei)粗鋼日均產(chan)量為兩百零九萬噸，環(huan)比下降3.3%，創出今年(nian)以來水平(ping)，但是當前(qian)減產(chan)受到季(ji)節性(xing)因素(su)支撐(cheng)，市(shi)場(chang)(chang)對數(shu)據(ju)(ju)(ju)有(you)效(xiao)性(xing)提(ti)出質疑。鍍鋅卷(juan)工業(ye)品而言(yan)，近期陸續(xu)公布的(de)重要數(shu)據(ju)(ju)(ju)中性(xing)偏多。但值得注意(yi)的(de)是，同年(nian)十一月熱(re)(re)鍍鋅卷(juan)板價(jia)格工業(ye)增加值和(he)投資增速放緩，進一步印證了國內(nei)總需(xu)求(qiu)乏(fa)力，工業(ye)復蘇形勢不容樂(le)觀。加上未來經濟結構調整等因素(su)，工業(ye)品價(jia)格反彈高度將有(you)限。傳統需(xu)求(qiu)淡季(ji)效(xiao)應(ying)還在持續(xu)不斷(duan)地(di)發酵，冬儲效(xiao)果不佳。雖(sui)然(ran)數(shu)據(ju)(ju)(ju)顯(xian)示供應(ying)壓力開始減輕，但是目前(qian)處(chu)于(yu)鋼鐵(tie)需(xu)求(qiu)淡季(ji)，市(shi)場(chang)(chang)成交萎縮，下游采購遲(chi)遲(chi)未能有(you)效(xiao)跟進，市(shi)場(chang)(chang)信心不足，鍍鋅鋼板貿易商囤貨現象(xiang)也不明顯(xian)。

鍍(du)(du)鋅(xin)鋼板(ban)按(an)用(yong)(yong)(yong)途又可分為一般(ban)用(yong)(yong)(yong)、屋頂用(yong)(yong)(yong)、建(jian)筑外側板(ban)用(yong)(yong)(yong)、結構(gou)用(yong)(yong)(yong)、瓦壟板(ban)用(yong)(yong)(yong)、拉伸用(yong)(yong)(yong)和深沖(chong)用(yong)(yong)(yong)等鍍(du)(du)鋅(xin)鋼板(ban)。熱鍍(du)(du)鋅(xin)板(ban)主要應用(yong)(yong)(yong)于建(jian)筑外用(yong)(yong)(yong)，建(jian)筑內用(yong)(yong)(yong)，民用(yong)(yong)(yong)，門窗，家具，機(ji)(ji)械，電(dian)子及家用(yong)(yong)(yong)電(dian)器等領(ling)域(yu)。也(ye)有機(ji)(ji)箱用(yong)(yong)(yong)這(zhe)(zhe)個(ge)(ge)，不過熱鍍(du)(du)鋅(xin)板(ban)不放(fang)輻(fu)射的。空調，冰箱，微波爐及其類似家電(dian)背面(mian)的那個(ge)(ge)板(ban)就是(shi)熱鍍(du)(du)鋅(xin)板(ban)。鍍(du)(du)鋅(xin)層通過鈍化(hua)處(chu)理，可減少潮溫貯運條件下產生折銹蝕(白(bai)銹) 。但這(zhe)(zhe)種(zhong)化(hua)學處(chu)理的防(fang)腐蝕性能是(shi)有限的，而且，妨礙(ai)大多數涂料的附著性。這(zhe)(zhe)種(zhong)處(chu)理一般(ban)不用(yong)(yong)(yong)在鋅(xin)鐵合金(jin)鍍(du)(du)層，除光整表(biao)面(mian)外，作(zuo)為常(chang)規，生產廠對其他類型的鍍(du)(du)鋅(xin)層均進行鈍化(hua)處(chu)理。

鍍(du)鋅(xin)(xin)是一(yi)(yi)(yi)種經常采(cai)用(yong)的經濟(ji)而(er)有效的防(fang)腐(fu)方法。鋅(xin)(xin)產量的一(yi)(yi)(yi)半左右均用(yong)于(yu)此種工藝(yi)。鍍(du)鋅(xin)(xin)卷是為防(fang)止鋼(gang)(gang)板(ban)(ban)表面(mian)遭受腐(fu)蝕延長其使用(yong)壽命(ming)，在鋼(gang)(gang)板(ban)(ban)表面(mian)涂(tu)以一(yi)(yi)(yi)層金屬鋅(xin)(xin)，這種涂(tu)鋅(xin)(xin)的鋼(gang)(gang)板(ban)(ban)稱(cheng)為鍍(du)鋅(xin)(xin)卷。鍍(du)鋅(xin)(xin)卷主要用(yong)于(yu)建筑、家電、汽車(che)、容器、交通及家業等領域(yu)。特別是鋼(gang)(gang)結構建筑、汽車(che)制(zhi)造(zao)(zao)、鋼(gang)(gang)板(ban)(ban)倉(cang)制(zhi)造(zao)(zao)等行業。耐腐(fu)蝕強(qiang)、表面(mian)質量好(hao)、得利于(yu)深加工、經濟(ji)實用(yong)等。有關產品標準都列明(ming)鍍(du)鋅(xin)(xin)卷推薦的標準厚(hou)度(du)(du)(du)、長度(du)(du)(du)和寬度(du)(du)(du)及其允(yun)許偏差。鍍(du)鋅(xin)(xin)卷厚(hou)度(du)(du)(du)偏差一(yi)(yi)(yi)般在0.05mm，長寬偏差一(yi)(yi)(yi)般在5mm ，板(ban)(ban)材的厚(hou)度(du)(du)(du)一(yi)(yi)(yi)般在0.2-3.2之間 。
