白鐵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。彭州白鐵鍍鋅(xin)卷工(gong)(gong)業(ye)品(pin)而言，近期陸續公布的重要數據中性偏多。但值(zhi)得注意(yi)的是，同年十一(yi)月熱鍍鋅(xin)卷板(ban)價格工(gong)(gong)業(ye)增加值(zhi)和投資增速放(fang)緩，進一(yi)步印證了國內總需(xu)求(qiu)(qiu)乏力，工(gong)(gong)業(ye)復蘇(su)形勢不(bu)(bu)(bu)容(rong)樂觀(guan)。加上未來經(jing)濟結構調(diao)整等因素，工(gong)(gong)業(ye)品(pin)價格反彈高度將(jiang)有(you)限。傳(chuan)統(tong)需(xu)求(qiu)(qiu)淡季效(xiao)應還在持續不(bu)(bu)(bu)斷地發酵，冬儲效(xiao)果不(bu)(bu)(bu)佳。雖然數據顯(xian)示供(gong)應壓(ya)力開始減輕，但是目前處于鋼鐵需(xu)求(qiu)(qiu)淡季，市(shi)(shi)場成交萎縮，下游采購(gou)遲遲未能有(you)效(xiao)跟進，市(shi)(shi)場信(xin)心(xin)不(bu)(bu)(bu)足，鍍鋅(xin)鋼板(ban)貿易商囤貨現象也不(bu)(bu)(bu)明顯(xian)。
