鍍鋅板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。遼寧鍍鋅板鍍(du)鋅(xin)卷工(gong)業品而言，近期陸續公(gong)布的(de)(de)重要數據中性偏多。但值(zhi)(zhi)得注意的(de)(de)是，同年十一月熱鍍(du)鋅(xin)卷板價(jia)格(ge)工(gong)業增加值(zhi)(zhi)和投資增速放(fang)緩，進一步印證了國內總需求(qiu)乏力，工(gong)業復蘇形勢不(bu)容樂觀。加上未來經濟結構(gou)調整(zheng)等因(yin)素，工(gong)業品價(jia)格(ge)反彈高(gao)度將有限。傳統需求(qiu)淡(dan)季效應還在持續不(bu)斷地(di)發酵(jiao)，冬(dong)儲效果不(bu)佳(jia)。雖然數據顯示供(gong)應壓力開始減輕，但是目前處于鋼鐵需求(qiu)淡(dan)季，市場(chang)成交(jiao)萎縮(suo)，下游采購遲遲未能有效跟進，市場(chang)信心不(bu)足，鍍(du)鋅(xin)鋼板貿易商囤(dun)貨(huo)現象(xiang)也(ye)不(bu)明(ming)顯。
