鍍(du)(du)(du)(du)鋅(xin)(xin)(xin)(xin)鋼(gang)板(ban)(ban)(ban)按用(yong)(yong)途又可分(fen)為一般用(yong)(yong)、屋(wu)頂用(yong)(yong)、建筑外側(ce)板(ban)(ban)(ban)用(yong)(yong)、結構(gou)用(yong)(yong)、瓦壟板(ban)(ban)(ban)用(yong)(yong)、拉伸用(yong)(yong)和深沖用(yong)(yong)等鍍(du)(du)(du)(du)鋅(xin)(xin)(xin)(xin)鋼(gang)板(ban)(ban)(ban)。熱(re)鍍(du)(du)(du)(du)鋅(xin)(xin)(xin)(xin)板(ban)(ban)(ban)主要應用(yong)(yong)于建筑外用(yong)(yong)，建筑內用(yong)(yong)，民用(yong)(yong)，門(men)窗，家具，機械，電子及家用(yong)(yong)電器等領域。也有機箱用(yong)(yong)這個(ge)，不過(guo)熱(re)鍍(du)(du)(du)(du)鋅(xin)(xin)(xin)(xin)板(ban)(ban)(ban)不放輻射的(de)。空調，冰箱，微波爐(lu)及其(qi)(qi)類似家電背面(mian)的(de)那個(ge)板(ban)(ban)(ban)就是(shi)熱(re)鍍(du)(du)(du)(du)鋅(xin)(xin)(xin)(xin)板(ban)(ban)(ban)。鍍(du)(du)(du)(du)鋅(xin)(xin)(xin)(xin)層(ceng)通過(guo)鈍化處理，可減(jian)少潮(chao)溫貯運條(tiao)件下(xia)產生折(zhe)銹蝕(shi)(白銹) 。但這種化學處理的(de)防腐(fu)蝕(shi)性(xing)能是(shi)有限的(de)，而且，妨礙(ai)大多數涂料的(de)附著(zhu)性(xing)。這種處理一般不用(yong)(yong)在鋅(xin)(xin)(xin)(xin)鐵合(he)金鍍(du)(du)(du)(du)層(ceng)，除(chu)光整表(biao)面(mian)外，作為常(chang)規，生產廠對其(qi)(qi)他類型的(de)鍍(du)(du)(du)(du)鋅(xin)(xin)(xin)(xin)層(ceng)均進行鈍化處理。

重慶(qing)樓承板(ban)的(de)鍍(du)(du)鋅(xin)(xin)(xin)量沒有(you)(you)一個具體的(de)標準，制作壓型(xing)鋼(gang)(gang)板(ban)的(de)冷軋鋼(gang)(gang)卷須連(lian)續熱(re)浸(jin)鍍(du)(du)鋅(xin)(xin)(xin)（或鍍(du)(du)鋁(lv)(lv)(lv)鋅(xin)(xin)(xin)），鍍(du)(du)（鋁(lv)(lv)(lv)）鋅(xin)(xin)(xin)量視設計要求(qiu)而(er)定。樓承板(ban)用壓型(xing)鋼(gang)(gang)板(ban)宜選擇熱(re)浸(jin)鍍(du)(du)鋅(xin)(xin)(xin)鋼(gang)(gang)板(ban)。不允(yun)許使用電(dian)鍍(du)(du)鋅(xin)(xin)(xin)鋼(gang)(gang)板(ban)，電(dian)鍍(du)(du)鋅(xin)(xin)(xin)鋼(gang)(gang)板(ban)僅(jin)在(zai)基材表(biao)面形成保護層(ceng)，防(fang)腐(fu)能(neng)力有(you)(you)限。目前(qian)市(shi)場上有(you)(you)鍍(du)(du)鋅(xin)(xin)(xin)鋼(gang)(gang)板(ban)（鍍(du)(du)層(ceng)含鋁(lv)(lv)(lv)5%或55%），在(zai)酸(suan)性(xing)環境(jing)下的(de)防(fang)腐(fu)效果由于(yu)(yu)熱(re)浸(jin)鍍(du)(du)鋅(xin)(xin)(xin)鋼(gang)(gang)板(ban)，但在(zai)混(hun)凝土的(de)堿性(xing)條件(jian)下，鍍(du)(du)鋁(lv)(lv)(lv)鋅(xin)(xin)(xin)的(de)防(fang)腐(fu)蝕性(xing)能(neng)低于(yu)(yu)熱(re)浸(jin)鍍(du)(du)鋅(xin)(xin)(xin)鋼(gang)(gang)板(ban)，且鋁(lv)(lv)(lv)會(hui)和混(hun)凝土發(fa)生反(fan)應，并降(jiang)低混(hun)凝土與鋼(gang)(gang)板(ban)的(de)粘結(jie)性(xing)能(neng)。因此參考國外規(gui)范，及(ji)國內外工(gong)程(cheng)，行家(jia)壓型(xing)鋼(gang)(gang)板(ban)不建議使用鍍(du)(du)鋁(lv)(lv)(lv)鋅(xin)(xin)(xin)鋼(gang)(gang)板(ban)。

熱(re)(re)鍍(du)(du)(du)(du)鋅(xin)(xin)板(ban)和(he)電(dian)(dian)(dian)(dian)鍍(du)(du)(du)(du)鋅(xin)(xin)板(ban)在鍍(du)(du)(du)(du)鋅(xin)(xin)量上有很(hen)(hen)大的(de)(de)差別，就像山東彩涂卷(juan)）。熱(re)(re)鍍(du)(du)(du)(du)鋅(xin)(xin)的(de)(de)鍍(du)(du)(du)(du)鋅(xin)(xin)量不可能太小(xiao)，一般(ban)較(jiao)小(xiao)為雙面50～60g／m2，較(jiao)大可達600g／m2。電(dian)(dian)(dian)(dian)鍍(du)(du)(du)(du)鋅(xin)(xin)板(ban)的(de)(de)鍍(du)(du)(du)(du)鋅(xin)(xin)層可以很(hen)(hen)薄，較(jiao)小(xiao)達15g／m2，但要求鍍(du)(du)(du)(du)層較(jiao)厚(hou)的(de)(de)話則生產(chan)線速度很(hen)(hen)慢，不適應(ying)現代化機組的(de)(de)工藝特(te)點，一般(ban)較(jiao)大為lO0g／m2左右。正因為如此(ci)，電(dian)(dian)(dian)(dian)鍍(du)(du)(du)(du)鋅(xin)(xin)板(ban)的(de)(de)生產(chan)受到很(hen)(hen)大的(de)(de)限制。工一般(ban)電(dian)(dian)(dian)(dian)鍍(du)(du)(du)(du)鋅(xin)(xin)比較(jiao)多，適用(yong)(yong)于小(xiao)部(bu)件；熱(re)(re)鍍(du)(du)(du)(du)鋅(xin)(xin)一般(ban)用(yong)(yong)于電(dian)(dian)(dian)(dian)力設(she)備(bei)和(he)構件，適用(yong)(yong)于大的(de)(de)部(bu)件和(he)設(she)備(bei)。當然他們的(de)(de)價格(ge)也相對便宜一些。建(jian)設(she)部(bu)已正式(shi)下文，淘汰技術落(luo)后的(de)(de)冷鍍(du)(du)(du)(du)鋅(xin)(xin)管，不準用(yong)(yong)冷鍍(du)(du)(du)(du)鋅(xin)(xin)管作水、煤氣管。

熱鍍(du)(du)(du)鋅(xin)卷(juan)板(ban)(ban)(ban)價格行業(ye)統計數據(ju)顯(xian)示，十(shi)一月國(guo)內(nei)(nei)粗鋼(gang)日均(jun)產量為兩百零九萬噸，環比下(xia)降(jiang)3.3%，創(chuang)出今年(nian)以來(lai)水平(ping)，但是(shi)當前減產受到季(ji)節性(xing)因素支(zhi)撐，市(shi)場對數據(ju)有效性(xing)提出質疑。鍍(du)(du)(du)鋅(xin)卷(juan)工(gong)業(ye)品(pin)而言，近期陸續公布的(de)重要數據(ju)中性(xing)偏多(duo)。但值(zhi)得注(zhu)意的(de)是(shi)，同(tong)年(nian)十(shi)一月熱鍍(du)(du)(du)鋅(xin)卷(juan)板(ban)(ban)(ban)價格工(gong)業(ye)增(zeng)加(jia)(jia)值(zhi)和投資增(zeng)速(su)放緩，進一步印證(zheng)了(le)國(guo)內(nei)(nei)總需求乏力(li)，工(gong)業(ye)復(fu)蘇形勢不容樂觀。加(jia)(jia)上(shang)未(wei)來(lai)經濟結(jie)構調整等(deng)因素，工(gong)業(ye)品(pin)價格反(fan)彈高度將有限。傳統需求淡(dan)季(ji)效應還在持續不斷地發(fa)酵，冬儲效果不佳。雖然數據(ju)顯(xian)示供應壓力(li)開始減輕，但是(shi)目前處于鋼(gang)鐵需求淡(dan)季(ji)，市(shi)場成(cheng)交萎(wei)縮(suo)，下(xia)游采購遲(chi)遲(chi)未(wei)能有效跟進，市(shi)場信心不足，鍍(du)(du)(du)鋅(xin)鋼(gang)板(ban)(ban)(ban)貿易商囤貨現象也不明顯(xian)。

河南鍍鋅近期鋼價延續低迷，隨著通國規模的酷暑和旱季到來，熱鍍鋅卷板價格商場逐漸進入需要旺季，海內鋼鐵商場或將窄幅調整。在決策層兩手抓制度措施落實狀況、貨銀本位度定向寬松力度加大的直觀層面利好牽動下，商場信念逐漸趨穩，短期海內鋼價無望止跌企穩;另一上面，以后鋼價殺跌電能有余，而上漲也仍然屏障重重。鍍鋅廠家熱鍍鋅卷(juan)板價格價錢(qian)或將長(chang)期在于低位運行場(chang)面(mian)。
