熱(re)鍍(du)鋅(xin)卷(juan)板(ban)價(jia)格(ge)(ge)行業(ye)統計數據顯示(shi)，十一月國內粗(cu)鋼日均產量為兩百零九萬噸，環比(bi)下(xia)降(jiang)3.3%，創(chuang)出(chu)今年以來水平(ping)，但是當前(qian)減產受到(dao)季節性(xing)因(yin)素(su)支撐，市場對數據有效性(xing)提(ti)出(chu)質疑。鍍(du)鋅(xin)卷(juan)工(gong)業(ye)品而言，近期陸續公布的重要數據中性(xing)偏多。但值得注意的是，同年十一月熱(re)鍍(du)鋅(xin)卷(juan)板(ban)價(jia)格(ge)(ge)工(gong)業(ye)增加值和投資增速放(fang)緩，進一步印證了國內總(zong)需(xu)求(qiu)乏力(li)，工(gong)業(ye)復蘇形勢不容樂觀(guan)。加上未(wei)來經濟結構調整(zheng)等因(yin)素(su)，工(gong)業(ye)品價(jia)格(ge)(ge)反彈高度將有限。傳統需(xu)求(qiu)淡季效應(ying)還在持續不斷地發酵，冬儲效果不佳。雖(sui)然數據顯示(shi)供應(ying)壓力(li)開(kai)始減輕，但是目前(qian)處于(yu)鋼鐵需(xu)求(qiu)淡季，市場成(cheng)交(jiao)萎(wei)縮，下(xia)游采(cai)購(gou)遲遲未(wei)能(neng)有效跟進，市場信心不足，鍍(du)鋅(xin)鋼板(ban)貿易商(shang)囤貨(huo)現象(xiang)也(ye)不明顯。

電鍍鋅價格鍍鋅鋼板為基板的彩涂鋼板，除有鋅保護外，鋅層上的有機涂層起了覆蓋隔離作用，可防止鋼板生銹，使用壽命比鍍鋅鋼板更長，據介紹涂層鋼板的使用壽命比鍍鋅鋼板長50%。蘇州電鍍鋅在連續(xu)機(ji)組上(shang)以冷軋帶鋼，鍍鋅帶鋼（電鍍鋅和熱(re)鍍鋅）為基(ji)板(ban)(ban)(ban)(ban)(ban)(ban)，經過表面預處(chu)理（脫脂和化學(xue)處(chu)理），用輥涂的(de)方法，涂上(shang)一層(ceng)(ceng)或(huo)多層(ceng)(ceng)液(ye)態涂料，經過烘烤(kao)和冷卻所得的(de)板(ban)(ban)(ban)(ban)(ban)(ban)材即為涂層(ceng)(ceng)鋼板(ban)(ban)(ban)(ban)(ban)(ban)。由于(yu)涂層(ceng)(ceng)可以有各種不同的(de)顏色(se)(se)，習慣上(shang)把涂層(ceng)(ceng)鋼板(ban)(ban)(ban)(ban)(ban)(ban)叫做彩色(se)(se)涂層(ceng)(ceng)鋼板(ban)(ban)(ban)(ban)(ban)(ban)。又由于(yu)涂層(ceng)(ceng)是在鋼板(ban)(ban)(ban)(ban)(ban)(ban)成型加工之(zhi)前進行的(de)，在國外這叫做預涂層(ceng)(ceng)鋼板(ban)(ban)(ban)(ban)(ban)(ban)。
