西昌白鐵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。白鐵批發為克(ke)服單面(mian)未涂鋅的缺點，又(you)(you)有一種在另面(mian)涂以薄層鋅的鍍鋅板(ban)，即雙(shuang)面(mian)差鍍鋅板(ban)；合(he)金(jin)、復合(he)鍍鋅鋼(gang)板(ban)。它是用鋅和其(qi)他金(jin)屬如鉛、鋅制成合(he)金(jin)乃至復合(he)鍍成的鋼(gang)板(ban)。這種鋼(gang)板(ban)既具有防銹性(xing)能(neng)，又(you)(you)有良好的涂裝性(xing)能(neng)。
