四川鍍鋅板重慶鍍鋅板按生產及加工方法可分為以下幾類： 熱浸鍍鋅鋼板。將薄鋼板浸入熔解的鋅槽中，使其表面粘附一層鋅的薄鋼板。目前主要采用連續鍍鋅工藝生產，即把成卷的鋼板連續浸在熔解有鋅的鍍槽中制成鍍鋅鋼板； 合金化鍍鋅鋼板。鍍鋅板批發為克服單面(mian)未涂(tu)鋅(xin)(xin)的(de)缺點，又有(you)一種(zhong)在另面(mian)涂(tu)以薄層(ceng)鋅(xin)(xin)的(de)鍍(du)鋅(xin)(xin)板(ban)(ban)，即雙(shuang)面(mian)差鍍(du)鋅(xin)(xin)板(ban)(ban)；合(he)金(jin)、復合(he)鍍(du)鋅(xin)(xin)鋼(gang)板(ban)(ban)。它是用鋅(xin)(xin)和其他(ta)金(jin)屬如鉛、鋅(xin)(xin)制(zhi)成合(he)金(jin)乃(nai)至(zhi)復合(he)鍍(du)成的(de)鋼(gang)板(ban)(ban)。這種(zhong)鋼(gang)板(ban)(ban)既具有(you)防銹性能，又有(you)良(liang)好的(de)涂(tu)裝(zhuang)性能。

鍍鋅(xin)(xin)(xin)鋼(gang)(gang)板(ban)(ban)是為(wei)防止鋼(gang)(gang)板(ban)(ban)表面遭受腐蝕(shi)，延(yan)長其(qi)使用(yong)壽命(ming)，在鋼(gang)(gang)板(ban)(ban)表面涂(tu)以一層金(jin)屬鋅(xin)(xin)(xin)，這(zhe)(zhe)種涂(tu)鋅(xin)(xin)(xin)的(de)(de)薄鋼(gang)(gang)板(ban)(ban)稱為(wei)鍍鋅(xin)(xin)(xin)板(ban)(ban)。按生產(chan)及(ji)加工(gong)方法(fa)可(ke)分為(wei)以下(xia)幾類：熱浸(jin)鍍鋅(xin)(xin)(xin)鋼(gang)(gang)板(ban)(ban)。將薄鋼(gang)(gang)板(ban)(ban)浸(jin)入熔(rong) 微(wei)商貨源(yuan)解的(de)(de)鋅(xin)(xin)(xin)槽中，使其(qi)表面粘附一層鋅(xin)(xin)(xin)的(de)(de)薄鋼(gang)(gang)板(ban)(ban)。目前主要采用(yong)連續鍍鋅(xin)(xin)(xin)工(gong)藝生產(chan)，即(ji)把(ba)成卷的(de)(de)鋼(gang)(gang)板(ban)(ban)連續浸(jin)在熔(rong)解有鋅(xin)(xin)(xin)的(de)(de)鍍槽中制成鍍鋅(xin)(xin)(xin)鋼(gang)(gang)板(ban)(ban)；合金(jin)化鍍鋅(xin)(xin)(xin)鋼(gang)(gang)板(ban)(ban)。這(zhe)(zhe)種鋼(gang)(gang)板(ban)(ban)也是用(yong)熱浸(jin)法(fa)制造，但在出槽后，立(li)即(ji)把(ba)它加熱到５００℃左右(you)，使其(qi)生成鋅(xin)(xin)(xin)和鐵的(de)(de)合金(jin)被膜。這(zhe)(zhe)種鍍鋅(xin)(xin)(xin)板(ban)(ban)具有良好(hao)的(de)(de)涂(tu)料的(de)(de)密著性(xing)和焊接性(xing)。
