鍍(du)鋅(xin)鋼(gang)(gang)板按用(yong)(yong)(yong)(yong)(yong)途又可分為一般(ban)用(yong)(yong)(yong)(yong)(yong)、屋頂用(yong)(yong)(yong)(yong)(yong)、建(jian)(jian)(jian)筑外(wai)側板用(yong)(yong)(yong)(yong)(yong)、結構用(yong)(yong)(yong)(yong)(yong)、瓦壟板用(yong)(yong)(yong)(yong)(yong)、拉伸用(yong)(yong)(yong)(yong)(yong)和深沖用(yong)(yong)(yong)(yong)(yong)等(deng)鍍(du)鋅(xin)鋼(gang)(gang)板。熱鍍(du)鋅(xin)板主要應用(yong)(yong)(yong)(yong)(yong)于建(jian)(jian)(jian)筑外(wai)用(yong)(yong)(yong)(yong)(yong)，建(jian)(jian)(jian)筑內用(yong)(yong)(yong)(yong)(yong)，民(min)用(yong)(yong)(yong)(yong)(yong)，門窗，家具，機械，電(dian)子及家用(yong)(yong)(yong)(yong)(yong)電(dian)器(qi)等(deng)領域。也有機箱(xiang)用(yong)(yong)(yong)(yong)(yong)這個，不過(guo)熱鍍(du)鋅(xin)板不放(fang)輻(fu)射的(de)。空調，冰箱(xiang)，微波爐及其(qi)(qi)類(lei)似家電(dian)背面的(de)那個板就是熱鍍(du)鋅(xin)板。鍍(du)鋅(xin)層通過(guo)鈍(dun)化處(chu)(chu)理，可減少(shao)潮溫貯運條件(jian)下(xia)產(chan)(chan)生折銹蝕(白(bai)銹) 。但這種(zhong)化學(xue)處(chu)(chu)理的(de)防(fang)腐蝕性(xing)能是有限的(de)，而且，妨礙大(da)多數涂料的(de)附(fu)著(zhu)性(xing)。這種(zhong)處(chu)(chu)理一般(ban)不用(yong)(yong)(yong)(yong)(yong)在鋅(xin)鐵合金鍍(du)層，除光(guang)整(zheng)表面外(wai)，作為常(chang)規，生產(chan)(chan)廠對其(qi)(qi)他類(lei)型(xing)的(de)鍍(du)鋅(xin)層均進(jin)行鈍(dun)化處(chu)(chu)理。

鍍(du)(du)鋅(xin)卷分(fen)熱鍍(du)(du)鋅(xin)和(he)電(dian)鍍(du)(du)鋅(xin)兩種，熱鍍(du)(du)鋅(xin)鍍(du)(du)鋅(xin)層厚，具有(you)鍍(du)(du)層均勻，附著力強，使用(yong)壽(shou)命長等優點(dian)。電(dian)鍍(du)(du)鋅(xin)成本低，表面不是很(hen)(hen)光滑，其本身的(de)耐(nai)腐蝕(shi)性(xing)比熱鍍(du)(du)鋅(xin)管相差很(hen)(hen)多。提起鍍(du)(du)鋅(xin)管，可能沒(mei)接觸(chu)過建材的(de)朋友并不了(le)解。從1935年建立一條(tiao)連(lian)續涂(tu)層鋼板(ban)(ban)線開始，彩涂(tu)板(ban)(ban)得到了(le)廣泛應(ying)用(yong)，目前彩涂(tu)板(ban)(ban)的(de)品種繁多，大約(yue)超(chao)過600種，彩涂(tu)板(ban)(ban)兼有(you)機(ji)聚合物(wu)與鋼板(ban)(ban)兩者的(de)優點(dian)，既有(you)有(you)機(ji)聚合物(wu)的(de)良好著色性(xing)、成型性(xing)、耐(nai)蝕(shi)性(xing)、裝飾性(xing)、又有(you)鋼板(ban)(ban)的(de)高強度和(he)易加工性(xing)，能很(hen)(hen)容易地進行沖壓裁剪、彎曲、深沖等加工。

鍍鋅方(fang)管是一(yi)(yi)種具以熱軋(ya)或(huo)(huo)冷(leng)(leng)軋(ya)鍍鋅帶(dai)鋼(gang)(gang)(gang)或(huo)(huo)鍍鋅卷(juan)板(ban)為坯料經冷(leng)(leng)彎曲加(jia)工(gong)成(cheng)型后(hou)再經高(gao)頻焊接制(zhi)成(cheng)的(de)(de)方(fang)形(xing)截(jie)面形(xing)狀尺寸的(de)(de)空(kong)心(xin)方(fang)形(xing)的(de)(de)截(jie)面型鋼(gang)(gang)(gang)鋼(gang)(gang)(gang)管;或(huo)(huo)將(jiang)事先(xian)做(zuo)好的(de)(de)冷(leng)(leng)彎空(kong)心(xin)型鋼(gang)(gang)(gang)管再經熱浸(jin)鍍鋅加(jia)工(gong)而(er)成(cheng)的(de)(de)鍍鋅方(fang)矩管。鍍鋅卷(juan)廠產(chan)量隨著(zhu)國(guo)民(min)生活(huo)水平不(bu)(bu)斷提高(gao)和(he)城市化(hua)建設的(de)(de)不(bu)(bu)斷推(tui)進，從現在的(de)(de)1.6億噸(dun)每年，增加(jia)到3億噸(dun)甚至更(geng)多也不(bu)(bu)是什么(me)很遙(yao)遠的(de)(de)夢想。作為煉鋼(gang)(gang)(gang)原(yuan)料的(de)(de)鐵礦石(shi)與廢鋼(gang)(gang)(gang)，前者是不(bu)(bu)可(ke)的(de)(de)資源(yuan)，后(hou)者是可(ke)以循環(huan)(huan)利用(yong)的(de)(de)資源(yuan)。無論從環(huan)(huan)保角度還是從鋼(gang)(gang)(gang)企的(de)(de)運作成(cheng)本上看，廢鋼(gang)(gang)(gang)都有著(zhu)礦石(shi)所(suo)無法比擬(ni)的(de)(de)優(you)勢(shi)。發展(zhan)高(gao)強度熱鍍鋅鋼(gang)(gang)(gang)板(ban)。隨著(zhu)汽(qi)(qi)車工(gong)業逐漸向(xiang)、節能方(fang)向(xiang)發展(zhan)，對(dui)汽(qi)(qi)車用(yong)鍍鋅鋼(gang)(gang)(gang)板(ban)性(xing)(xing)能要求也進一(yi)(yi)步提高(gao)。為了汽(qi)(qi)車板(ban)的(de)(de)耐腐蝕性(xing)(xing)，將(jiang)擴大(da)熱鍍鋅鋼(gang)(gang)(gang)板(ban)的(de)(de)使用(yong)率。

鍍鋅鋼管價格熱鍍鋅板和電鍍鋅板在鍍鋅量上有很大的差別，就像山東彩涂卷）。熱鍍鋅的鍍鋅量不可能太小，一般較小為雙面50～60g／m2，較大可達600g／m2。開遠鍍鋅鋼管電鍍(du)(du)鋅(xin)(xin)板的(de)鍍(du)(du)鋅(xin)(xin)層可以很薄，較(jiao)小達(da)15g／m2，但(dan)要求鍍(du)(du)層較(jiao)厚的(de)話則生產線速度很慢(man)，不適應(ying)現代化機組的(de)工藝(yi)特點，一(yi)般較(jiao)大(da)為lO0g／m2左(zuo)右。正因為如此，電鍍(du)(du)鋅(xin)(xin)板的(de)生產受到(dao)很大(da)的(de)限制。工一(yi)般電鍍(du)(du)鋅(xin)(xin)比較(jiao)多，適用(yong)(yong)于小部(bu)(bu)件；熱(re)鍍(du)(du)鋅(xin)(xin)一(yi)般用(yong)(yong)于電力設備(bei)和構(gou)件，適用(yong)(yong)于大(da)的(de)部(bu)(bu)件和設備(bei)。當然他們的(de)價格(ge)也相對便(bian)宜一(yi)些。建(jian)設部(bu)(bu)已正式下文，淘汰技術落(luo)后(hou)的(de)冷(leng)鍍(du)(du)鋅(xin)(xin)管(guan)，不準用(yong)(yong)冷(leng)鍍(du)(du)鋅(xin)(xin)管(guan)作(zuo)水、煤氣管(guan)。
