鍍鋅(xin)(xin)(xin)鋼(gang)板(ban)(ban)(ban)是為防止鋼(gang)板(ban)(ban)(ban)表(biao)面遭受腐蝕(shi)，延長其使(shi)用(yong)(yong)壽命，在鋼(gang)板(ban)(ban)(ban)表(biao)面涂以一層金屬(shu)鋅(xin)(xin)(xin)，這(zhe)種涂鋅(xin)(xin)(xin)的(de)薄(bo)(bo)鋼(gang)板(ban)(ban)(ban)稱為鍍鋅(xin)(xin)(xin)板(ban)(ban)(ban)。按(an)生(sheng)(sheng)產及加工方法可分(fen)為以下幾(ji)類(lei)：熱浸(jin)鍍鋅(xin)(xin)(xin)鋼(gang)板(ban)(ban)(ban)。將(jiang)薄(bo)(bo)鋼(gang)板(ban)(ban)(ban)浸(jin)入熔(rong) 微商貨源解的(de)鋅(xin)(xin)(xin)槽中，使(shi)其表(biao)面粘附一層鋅(xin)(xin)(xin)的(de)薄(bo)(bo)鋼(gang)板(ban)(ban)(ban)。目前主要采用(yong)(yong)連續鍍鋅(xin)(xin)(xin)工藝生(sheng)(sheng)產，即把(ba)成(cheng)卷的(de)鋼(gang)板(ban)(ban)(ban)連續浸(jin)在熔(rong)解有(you)鋅(xin)(xin)(xin)的(de)鍍槽中制成(cheng)鍍鋅(xin)(xin)(xin)鋼(gang)板(ban)(ban)(ban)；合金化鍍鋅(xin)(xin)(xin)鋼(gang)板(ban)(ban)(ban)。這(zhe)種鋼(gang)板(ban)(ban)(ban)也是用(yong)(yong)熱浸(jin)法制造，但在出槽后，立即把(ba)它加熱到５００℃左(zuo)右，使(shi)其生(sheng)(sheng)成(cheng)鋅(xin)(xin)(xin)和(he)鐵的(de)合金被膜。這(zhe)種鍍鋅(xin)(xin)(xin)板(ban)(ban)(ban)具有(you)良好的(de)涂料的(de)密著性和(he)焊(han)接性。

重慶鍍(du)(du)(du)鋅(xin)(xin)板(ban)(ban)(ban)按生(sheng)產(chan)(chan)及加(jia)工(gong)方法可(ke)分為以下幾類(lei)： 熱(re)浸鍍(du)(du)(du)鋅(xin)(xin)鋼(gang)(gang)(gang)板(ban)(ban)(ban)。將薄(bo)鋼(gang)(gang)(gang)板(ban)(ban)(ban)浸入熔解(jie)的(de)(de)(de)鋅(xin)(xin)槽中，使其表面(mian)(mian)粘附一層鋅(xin)(xin)的(de)(de)(de)薄(bo)鋼(gang)(gang)(gang)板(ban)(ban)(ban)。目前(qian)主要采用連續鍍(du)(du)(du)鋅(xin)(xin)工(gong)藝生(sheng)產(chan)(chan)，即(ji)把成(cheng)卷的(de)(de)(de)鋼(gang)(gang)(gang)板(ban)(ban)(ban)連續浸在熔解(jie)有(you)(you)鋅(xin)(xin)的(de)(de)(de)鍍(du)(du)(du)槽中制(zhi)成(cheng)鍍(du)(du)(du)鋅(xin)(xin)鋼(gang)(gang)(gang)板(ban)(ban)(ban)； 合(he)金化(hua)鍍(du)(du)(du)鋅(xin)(xin)鋼(gang)(gang)(gang)板(ban)(ban)(ban)。為克(ke)服單面(mian)(mian)未涂鋅(xin)(xin)的(de)(de)(de)缺(que)點，又(you)有(you)(you)一種在另面(mian)(mian)涂以薄(bo)層鋅(xin)(xin)的(de)(de)(de)鍍(du)(du)(du)鋅(xin)(xin)板(ban)(ban)(ban)，即(ji)雙(shuang)面(mian)(mian)差鍍(du)(du)(du)鋅(xin)(xin)板(ban)(ban)(ban)；合(he)金、復(fu)合(he)鍍(du)(du)(du)鋅(xin)(xin)鋼(gang)(gang)(gang)板(ban)(ban)(ban)。它是(shi)用鋅(xin)(xin)和其他金屬如鉛(qian)、鋅(xin)(xin)制(zhi)成(cheng)合(he)金乃至(zhi)復(fu)合(he)鍍(du)(du)(du)成(cheng)的(de)(de)(de)鋼(gang)(gang)(gang)板(ban)(ban)(ban)。這種鋼(gang)(gang)(gang)板(ban)(ban)(ban)既具有(you)(you)防銹性能，又(you)有(you)(you)良好的(de)(de)(de)涂裝(zhuang)性能。

鍍鋅角鋼批發鍍鋅卷分熱鍍鋅和電鍍鋅兩種，熱鍍鋅鍍鋅層厚，具有鍍層均勻，附著力強，使用壽命長等優點。南寧鍍鋅角鋼電鍍鋅成本低，表(biao)面不是很光(guang)滑，其本身的(de)(de)耐(nai)腐蝕(shi)性比(bi)熱鍍鋅管相(xiang)差很多。提(ti)起鍍鋅管，可能(neng)沒接(jie)觸過(guo)建材的(de)(de)朋友并不了(le)解(jie)。從1935年(nian)建立一條(tiao)連(lian)續涂層鋼(gang)板線開始(shi)，彩(cai)(cai)涂板得到(dao)了(le)廣泛應用，目前(qian)彩(cai)(cai)涂板的(de)(de)品(pin)種(zhong)繁多，大約超過(guo)600種(zhong)，彩(cai)(cai)涂板兼有(you)機聚合(he)物(wu)與鋼(gang)板兩者的(de)(de)優點，既有(you)有(you)機聚合(he)物(wu)的(de)(de)良好著色(se)性、成型性、耐(nai)蝕(shi)性、裝飾(shi)性、又有(you)鋼(gang)板的(de)(de)高(gao)強度和易(yi)加(jia)(jia)工性，能(neng)很容易(yi)地(di)進行沖(chong)壓裁剪、彎(wan)曲、深沖(chong)等加(jia)(jia)工。
