熱鍍(du)鋅(xin)卷(juan)板價格行業統計數(shu)(shu)據顯(xian)示，十(shi)一月(yue)國(guo)內粗鋼(gang)(gang)日均(jun)產(chan)量為兩百(bai)零九萬噸，環(huan)比下(xia)降3.3%，創出今年(nian)以(yi)來(lai)水(shui)平，但是當(dang)前(qian)減(jian)產(chan)受到季節性因素支撐，市場對數(shu)(shu)據有效性提出質疑。鍍(du)鋅(xin)卷(juan)工(gong)(gong)(gong)業品(pin)而(er)言，近期陸續(xu)公布(bu)的(de)重要數(shu)(shu)據中性偏多。但值得注(zhu)意的(de)是，同年(nian)十(shi)一月(yue)熱鍍(du)鋅(xin)卷(juan)板價格工(gong)(gong)(gong)業增加(jia)值和投資增速放緩，進一步印證(zheng)了國(guo)內總需(xu)求乏力，工(gong)(gong)(gong)業復蘇形勢不(bu)(bu)容樂觀。加(jia)上未來(lai)經濟(ji)結(jie)構調整等因素，工(gong)(gong)(gong)業品(pin)價格反彈(dan)高度(du)將有限。傳統需(xu)求淡季效應(ying)還在(zai)持(chi)續(xu)不(bu)(bu)斷地(di)發酵(jiao)，冬儲效果不(bu)(bu)佳。雖(sui)然數(shu)(shu)據顯(xian)示供應(ying)壓力開始減(jian)輕，但是目(mu)前(qian)處于鋼(gang)(gang)鐵需(xu)求淡季，市場成交萎縮，下(xia)游采購(gou)遲遲未能有效跟進，市場信心不(bu)(bu)足，鍍(du)鋅(xin)鋼(gang)(gang)板貿(mao)易商囤貨(huo)現象也不(bu)(bu)明顯(xian)。

彩涂卷廠家熱浸鍍鋅鋼板將薄鋼板浸入熔解的鋅槽中，使其表面粘附一層鋅的薄鋼板。目前主要采用連續鍍鋅工藝生產，即把成卷的鋼板連續浸在熔解有鋅的鍍槽中制成鍍鋅鋼板;合金化鍍鋅鋼板。彭州酒鋼彩涂卷這(zhe)(zhe)種(zhong)鋼板(ban)(ban)也是(shi)用熱浸(jin)法制造，但在(zai)出槽(cao)后(hou)，立即把它加(jia)(jia)熱到500 ℃左右(you)，使(shi)其生成鋅(xin)和(he)鐵的(de)(de)合金被膜。這(zhe)(zhe)種(zhong)鍍(du)鋅(xin)板(ban)(ban)具有(you)(you)良(liang)(liang)好的(de)(de)涂(tu)料(liao)的(de)(de)密(mi)著(zhu)性和(he)焊(han)接性;電(dian)(dian)鍍(du)鋅(xin)鋼板(ban)(ban)。用電(dian)(dian)鍍(du)法制造這(zhe)(zhe)種(zhong)鍍(du)鋅(xin)鋼板(ban)(ban)具有(you)(you)良(liang)(liang)好的(de)(de)加(jia)(jia)工(gong)性。但鍍(du)層(ceng)較薄，耐腐蝕性不如熱浸(jin)法鍍(du)鋅(xin)板(ban)(ban);單面(mian)鍍(du)和(he)雙(shuang)面(mian)差鍍(du)鋅(xin)鋼板(ban)(ban)。單面(mian)鍍(du)鋅(xin)鋼板(ban)(ban)，即只在(zai)一(yi)面(mian)鍍(du)鋅(xin)的(de)(de)產(chan)品。在(zai)焊(han)接、涂(tu)裝(zhuang)、防(fang)銹(xiu)處(chu)理、加(jia)(jia)工(gong)等(deng)方面(mian)，具有(you)(you)比雙(shuang)面(mian)鍍(du)鋅(xin)板(ban)(ban)好的(de)(de)適應(ying)性。
