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。崇州鍍鋅板鍍鋅卷工(gong)業(ye)品而言(yan)，近期(qi)陸續(xu)公布的(de)重要數(shu)(shu)據中性偏多(duo)。但值得注意的(de)是，同年(nian)十一(yi)月熱鍍鋅卷板價(jia)格(ge)工(gong)業(ye)增(zeng)加值和投(tou)資增(zeng)速放(fang)緩，進(jin)一(yi)步(bu)印證了國內總(zong)需求(qiu)(qiu)乏(fa)力(li)，工(gong)業(ye)復蘇形勢(shi)不(bu)容樂(le)觀。加上(shang)未來經濟結構調整等(deng)因素，工(gong)業(ye)品價(jia)格(ge)反(fan)彈高度將有(you)限。傳統(tong)需求(qiu)(qiu)淡季效(xiao)(xiao)應(ying)還(huan)在持續(xu)不(bu)斷地發酵，冬儲效(xiao)(xiao)果不(bu)佳。雖然數(shu)(shu)據顯示供(gong)應(ying)壓力(li)開(kai)始減輕，但是目前處于鋼鐵需求(qiu)(qiu)淡季，市場成(cheng)交(jiao)萎縮(suo)，下游(you)采購遲(chi)遲(chi)未能有(you)效(xiao)(xiao)跟進(jin)，市場信心不(bu)足，鍍鋅鋼板貿易商囤貨現象也不(bu)明(ming)顯。
