熱(re)(re)鍍(du)鋅(xin)卷板(ban)(ban)價(jia)(jia)格行業(ye)(ye)統計數據(ju)(ju)顯(xian)示，十(shi)一月國(guo)內粗鋼日均(jun)產(chan)量為兩百零九萬(wan)噸，環比下降(jiang)3.3%，創出(chu)今年以來水平(ping)，但是當前(qian)減(jian)產(chan)受(shou)到(dao)季節性(xing)因素(su)支撐，市(shi)場(chang)對數據(ju)(ju)有效(xiao)(xiao)性(xing)提出(chu)質疑。鍍(du)鋅(xin)卷工(gong)(gong)業(ye)(ye)品而言，近(jin)期陸續公布(bu)的重要數據(ju)(ju)中性(xing)偏多(duo)。但值(zhi)(zhi)得注意(yi)的是，同(tong)年十(shi)一月熱(re)(re)鍍(du)鋅(xin)卷板(ban)(ban)價(jia)(jia)格工(gong)(gong)業(ye)(ye)增加值(zhi)(zhi)和投資(zi)增速放緩，進一步印證了(le)國(guo)內總需求(qiu)乏力，工(gong)(gong)業(ye)(ye)復(fu)蘇形勢不(bu)容(rong)樂觀(guan)。加上(shang)未來經濟結構(gou)調整等因素(su)，工(gong)(gong)業(ye)(ye)品價(jia)(jia)格反彈高度將有限。傳統需求(qiu)淡季效(xiao)(xiao)應還在(zai)持續不(bu)斷地發酵(jiao)，冬(dong)儲效(xiao)(xiao)果(guo)不(bu)佳。雖然(ran)數據(ju)(ju)顯(xian)示供(gong)應壓(ya)力開始減(jian)輕，但是目(mu)前(qian)處于鋼鐵需求(qiu)淡季，市(shi)場(chang)成交萎縮，下游采(cai)購(gou)遲(chi)遲(chi)未能(neng)有效(xiao)(xiao)跟進，市(shi)場(chang)信(xin)心不(bu)足(zu)，鍍(du)鋅(xin)鋼板(ban)(ban)貿易(yi)商囤貨現象也(ye)不(bu)明顯(xian)。

鍍鋅管批發熱鍍鋅生產發展一直處于滯后狀態。20世紀50年代到60年代陸續建成了13條單張鋼板熔劑法熱鍍鋅機組，能力為10萬t/a，但因產量低、成本高、質量差、污染環境、經濟效益差等缺陷已先后停、轉產。從20世紀70年代末，我國才開始建造大型寬帶熱鍍鋅機組。咸陽鍍鋅管熱鍍鋅帶鋼在(zai)我國(guo)市場(chang)一(yi)直是(shi)緊缺品種。從20世紀90年(nian)代中期(qi)以(yi)來，每年(nian)都(dou)要從國(guo)外進口80-100萬t左右。隨(sui)著國(guo)內(nei)經(jing)濟的發展(zhan)，尤其是(shi)汽車、家(jia)電及建筑業的發展(zhan)，對(dui)鍍鋅帶鋼的需求量(liang)也(ye)大(da)大(da)增加。
