鍍鋅角鋼價格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。廣東鍍鋅角鋼鍍(du)鋅(xin)卷(juan)工(gong)業(ye)品而言，近期陸續公布(bu)的(de)重要(yao)數據中性偏(pian)多。但值得注意的(de)是，同年十一(yi)月熱(re)鍍(du)鋅(xin)卷(juan)板價格(ge)工(gong)業(ye)增加(jia)(jia)值和投(tou)資增速放緩，進一(yi)步印(yin)證(zheng)了國內總(zong)需求(qiu)乏(fa)力(li)，工(gong)業(ye)復蘇形勢不(bu)容樂觀。加(jia)(jia)上未來經(jing)濟結構調整等因素，工(gong)業(ye)品價格(ge)反(fan)彈高(gao)度將(jiang)有(you)限。傳統需求(qiu)淡(dan)季效(xiao)應還(huan)在持續不(bu)斷地發酵，冬儲效(xiao)果不(bu)佳。雖然數據顯示供應壓(ya)力(li)開(kai)始減輕，但是目前處(chu)于鋼(gang)鐵需求(qiu)淡(dan)季，市(shi)場成交萎縮，下(xia)游采(cai)購遲遲未能(neng)有(you)效(xiao)跟進，市(shi)場信心不(bu)足(zu)，鍍(du)鋅(xin)鋼(gang)板貿易(yi)商囤貨現象也不(bu)明顯。

用(yong)(yong)電鍍(du)(du)(du)(du)法制造這種鍍(du)(du)(du)(du)鋅(xin)(xin)(xin)(xin)(xin)鋼(gang)(gang)(gang)板具(ju)有良好(hao)的(de)(de)(de)(de)加工性。但(dan)鍍(du)(du)(du)(du)層(ceng)(ceng)較薄，耐腐蝕性不如熱浸法鍍(du)(du)(du)(du)鋅(xin)(xin)(xin)(xin)(xin)板；單(dan)面(mian)鍍(du)(du)(du)(du)和(he)(he)雙面(mian)差(cha)(cha)鍍(du)(du)(du)(du)鋅(xin)(xin)(xin)(xin)(xin)鋼(gang)(gang)(gang)板。單(dan)面(mian)鍍(du)(du)(du)(du)鋅(xin)(xin)(xin)(xin)(xin)鋼(gang)(gang)(gang)板，即只在(zai)一(yi)面(mian)鍍(du)(du)(du)(du)鋅(xin)(xin)(xin)(xin)(xin)的(de)(de)(de)(de)產品。在(zai)焊接、涂(tu)(tu)裝(zhuang)(zhuang)、防銹處理、加工等(deng)方(fang)面(mian)，具(ju)有比(bi)雙面(mian)鍍(du)(du)(du)(du)鋅(xin)(xin)(xin)(xin)(xin)板好(hao)的(de)(de)(de)(de)適(shi)應性。為(wei)克服單(dan)面(mian)未涂(tu)(tu)鋅(xin)(xin)(xin)(xin)(xin)的(de)(de)(de)(de)缺點，又(you)有一(yi)種在(zai)另面(mian)涂(tu)(tu)以薄層(ceng)(ceng)鋅(xin)(xin)(xin)(xin)(xin)的(de)(de)(de)(de)鍍(du)(du)(du)(du)鋅(xin)(xin)(xin)(xin)(xin)板，即雙面(mian)差(cha)(cha)鍍(du)(du)(du)(du)鋅(xin)(xin)(xin)(xin)(xin)板；合金、復(fu)合鍍(du)(du)(du)(du)鋅(xin)(xin)(xin)(xin)(xin)鋼(gang)(gang)(gang)板。它是用(yong)(yong)鋅(xin)(xin)(xin)(xin)(xin)和(he)(he)其他金屬如鉛、鋅(xin)(xin)(xin)(xin)(xin)制成合金乃至復(fu)合鍍(du)(du)(du)(du)成的(de)(de)(de)(de)鋼(gang)(gang)(gang)板。這種鋼(gang)(gang)(gang)板既具(ju)有防銹性能，又(you)有良好(hao)的(de)(de)(de)(de)涂(tu)(tu)裝(zhuang)(zhuang)性能。 除上述五(wu)種外，還有彩色鍍(du)(du)(du)(du)鋅(xin)(xin)(xin)(xin)(xin)鋼(gang)(gang)(gang)板、印(yin)花涂(tu)(tu)裝(zhuang)(zhuang)鍍(du)(du)(du)(du)鋅(xin)(xin)(xin)(xin)(xin)鋼(gang)(gang)(gang)板、聚(ju)氯乙烯疊層(ceng)(ceng)鍍(du)(du)(du)(du)鋅(xin)(xin)(xin)(xin)(xin)鋼(gang)(gang)(gang)板等(deng)。但(dan)目前常用(yong)(yong)的(de)(de)(de)(de)仍為(wei)熱浸鍍(du)(du)(du)(du)鋅(xin)(xin)(xin)(xin)(xin)板。 鍍(du)(du)(du)(du)鋅(xin)(xin)(xin)(xin)(xin)鋼(gang)(gang)(gang)板按用(yong)(yong)途(tu)又(you)可分(fen)為(wei)一(yi)般用(yong)(yong)、屋頂用(yong)(yong)、建筑外側板用(yong)(yong)、結構用(yong)(yong)、瓦(wa)壟(long)板用(yong)(yong)、拉伸用(yong)(yong)和(he)(he)深沖用(yong)(yong)等(deng)鍍(du)(du)(du)(du)鋅(xin)(xin)(xin)(xin)(xin)鋼(gang)(gang)(gang)板。

熱鍍(du)(du)鋅(xin)(xin)(xin)板(ban)(ban)和(he)電鍍(du)(du)鋅(xin)(xin)(xin)板(ban)(ban)在鍍(du)(du)鋅(xin)(xin)(xin)量上有很大(da)的(de)差別，就像山東彩(cai)涂卷）。熱鍍(du)(du)鋅(xin)(xin)(xin)的(de)鍍(du)(du)鋅(xin)(xin)(xin)量不(bu)可能(neng)太小(xiao)，一(yi)般(ban)較(jiao)(jiao)(jiao)小(xiao)為(wei)雙面50～60g／m2，較(jiao)(jiao)(jiao)大(da)可達600g／m2。電鍍(du)(du)鋅(xin)(xin)(xin)板(ban)(ban)的(de)鍍(du)(du)鋅(xin)(xin)(xin)層可以很薄，較(jiao)(jiao)(jiao)小(xiao)達15g／m2，但(dan)要求鍍(du)(du)層較(jiao)(jiao)(jiao)厚的(de)話則生產線速度很慢，不(bu)適應現代化(hua)機組的(de)工(gong)藝特(te)點，一(yi)般(ban)較(jiao)(jiao)(jiao)大(da)為(wei)lO0g／m2左右。正因為(wei)如此(ci)，電鍍(du)(du)鋅(xin)(xin)(xin)板(ban)(ban)的(de)生產受到(dao)很大(da)的(de)限(xian)制(zhi)。工(gong)一(yi)般(ban)電鍍(du)(du)鋅(xin)(xin)(xin)比較(jiao)(jiao)(jiao)多，適用于小(xiao)部(bu)件；熱鍍(du)(du)鋅(xin)(xin)(xin)一(yi)般(ban)用于電力設(she)備和(he)構件，適用于大(da)的(de)部(bu)件和(he)設(she)備。當然他們的(de)價格也相對便宜一(yi)些。建(jian)設(she)部(bu)已正式(shi)下文，淘汰技(ji)術落后的(de)冷(leng)鍍(du)(du)鋅(xin)(xin)(xin)管(guan)，不(bu)準(zhun)用冷(leng)鍍(du)(du)鋅(xin)(xin)(xin)管(guan)作水、煤氣(qi)管(guan)。
