鍍鋅鋼板批發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。深圳鍍鋅鋼板鍍鋅(xin)卷工業(ye)品(pin)而言，近期陸續(xu)公布的重(zhong)要數據中性(xing)偏多。但值得注意的是(shi)，同年(nian)十一(yi)月熱鍍鋅(xin)卷板價格(ge)工業(ye)增加值和投資增速放緩(huan)，進(jin)一(yi)步印證了(le)國內總需求乏力，工業(ye)復蘇形(xing)勢不(bu)容(rong)樂觀(guan)。加上未來(lai)經濟(ji)結(jie)構調(diao)整(zheng)等(deng)因素，工業(ye)品(pin)價格(ge)反彈高度(du)將有限。傳統需求淡季(ji)效應(ying)還在(zai)持(chi)續(xu)不(bu)斷地(di)發酵，冬儲(chu)效果不(bu)佳。雖然數據顯(xian)示(shi)供應(ying)壓(ya)力開始減(jian)輕，但是(shi)目前處(chu)于鋼(gang)鐵需求淡季(ji)，市場(chang)成(cheng)交萎(wei)縮，下游采購遲遲未能有效跟進(jin)，市場(chang)信心(xin)不(bu)足，鍍鋅(xin)鋼(gang)板貿易商囤(dun)貨現象(xiang)也(ye)不(bu)明顯(xian)。
