熱鍍(du)(du)鋅(xin)(xin)卷板價格(ge)(ge)行(xing)業(ye)統計數據(ju)顯(xian)示，十一月(yue)國內粗鋼日均產量為(wei)兩百零(ling)九萬噸，環比下降3.3%，創出(chu)今年以來(lai)水平，但(dan)是當前(qian)減產受到(dao)季節性因(yin)素支撐，市(shi)場(chang)對數據(ju)有(you)效性提出(chu)質疑。鍍(du)(du)鋅(xin)(xin)卷工業(ye)品而言，近期陸續公(gong)布(bu)的重要數據(ju)中性偏多。但(dan)值得注意的是，同年十一月(yue)熱鍍(du)(du)鋅(xin)(xin)卷板價格(ge)(ge)工業(ye)增加(jia)值和投資增速放緩(huan)，進(jin)一步(bu)印證(zheng)了(le)國內總需求(qiu)(qiu)乏力(li)，工業(ye)復蘇形勢不容樂觀(guan)。加(jia)上未來(lai)經濟結構調(diao)整等因(yin)素，工業(ye)品價格(ge)(ge)反(fan)彈高度(du)將有(you)限(xian)。傳統需求(qiu)(qiu)淡季效應還在持續不斷(duan)地發酵，冬儲效果不佳。雖然數據(ju)顯(xian)示供應壓(ya)力(li)開始減輕(qing)，但(dan)是目前(qian)處于鋼鐵需求(qiu)(qiu)淡季，市(shi)場(chang)成交萎縮，下游采購遲遲未能(neng)有(you)效跟進(jin)，市(shi)場(chang)信心不足，鍍(du)(du)鋅(xin)(xin)鋼板貿易商(shang)囤貨(huo)現象也不明顯(xian)。

鍍鋅鋼批發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%。巫山鍍鋅鋼在(zai)連續機組上以冷(leng)軋帶鋼(gang)，鍍鋅帶鋼(gang)（電鍍鋅和熱鍍鋅）為基板(ban)(ban)，經過表面預處理(li)（脫(tuo)脂和化學處理(li)），用輥涂(tu)(tu)的(de)(de)方法，涂(tu)(tu)上一(yi)層(ceng)或多層(ceng)液態涂(tu)(tu)料，經過烘(hong)烤和冷(leng)卻所得的(de)(de)板(ban)(ban)材即為涂(tu)(tu)層(ceng)鋼(gang)板(ban)(ban)。由于涂(tu)(tu)層(ceng)可以有各種不同的(de)(de)顏(yan)色，習慣上把(ba)涂(tu)(tu)層(ceng)鋼(gang)板(ban)(ban)叫做彩色涂(tu)(tu)層(ceng)鋼(gang)板(ban)(ban)。又(you)由于涂(tu)(tu)層(ceng)是(shi)在(zai)鋼(gang)板(ban)(ban)成(cheng)型加工之(zhi)前進行的(de)(de)，在(zai)國(guo)外這(zhe)叫做預涂(tu)(tu)層(ceng)鋼(gang)板(ban)(ban)。
