鍍(du)鋅(xin)(xin)鋼板(ban)(ban)(ban)(ban)是為防止(zhi)鋼板(ban)(ban)(ban)(ban)表面遭受腐蝕，延長其(qi)使(shi)(shi)用(yong)壽命(ming)，在(zai)鋼板(ban)(ban)(ban)(ban)表面涂以一層金屬鋅(xin)(xin)，這(zhe)種涂鋅(xin)(xin)的(de)(de)(de)薄鋼板(ban)(ban)(ban)(ban)稱為鍍(du)鋅(xin)(xin)板(ban)(ban)(ban)(ban)。按生產及加工(gong)方法(fa)(fa)可分(fen)為以下幾類：熱(re)(re)浸(jin)鍍(du)鋅(xin)(xin)鋼板(ban)(ban)(ban)(ban)。將薄鋼板(ban)(ban)(ban)(ban)浸(jin)入熔 微商貨源解的(de)(de)(de)鋅(xin)(xin)槽中，使(shi)(shi)其(qi)表面粘附一層鋅(xin)(xin)的(de)(de)(de)薄鋼板(ban)(ban)(ban)(ban)。目前(qian)主要采用(yong)連續鍍(du)鋅(xin)(xin)工(gong)藝(yi)生產，即把成(cheng)卷的(de)(de)(de)鋼板(ban)(ban)(ban)(ban)連續浸(jin)在(zai)熔解有鋅(xin)(xin)的(de)(de)(de)鍍(du)槽中制(zhi)成(cheng)鍍(du)鋅(xin)(xin)鋼板(ban)(ban)(ban)(ban)；合金化(hua)鍍(du)鋅(xin)(xin)鋼板(ban)(ban)(ban)(ban)。這(zhe)種鋼板(ban)(ban)(ban)(ban)也是用(yong)熱(re)(re)浸(jin)法(fa)(fa)制(zhi)造，但在(zai)出槽后，立即把它加熱(re)(re)到５００℃左右，使(shi)(shi)其(qi)生成(cheng)鋅(xin)(xin)和(he)鐵的(de)(de)(de)合金被膜(mo)。這(zhe)種鍍(du)鋅(xin)(xin)板(ban)(ban)(ban)(ban)具有良(liang)好的(de)(de)(de)涂料的(de)(de)(de)密著性和(he)焊(han)接(jie)性。

四川鍍鋅板重慶樓承板的鍍鋅量沒有一個具體的標準，制作壓型鋼板的冷軋鋼卷須連續熱浸鍍鋅（或鍍鋁鋅），鍍（鋁）鋅量視設計要求而定。鍍鋅板批發樓承(cheng)板(ban)(ban)(ban)(ban)(ban)用壓型鋼(gang)(gang)板(ban)(ban)(ban)(ban)(ban)宜選擇熱(re)浸(jin)鍍(du)(du)鋅鋼(gang)(gang)板(ban)(ban)(ban)(ban)(ban)。不允許使用電鍍(du)(du)鋅鋼(gang)(gang)板(ban)(ban)(ban)(ban)(ban)，電鍍(du)(du)鋅鋼(gang)(gang)板(ban)(ban)(ban)(ban)(ban)僅在基材表面(mian)形成保護層(ceng)，防(fang)腐(fu)(fu)能力(li)有(you)(you)限。目(mu)前市場上有(you)(you)鍍(du)(du)鋅鋼(gang)(gang)板(ban)(ban)(ban)(ban)(ban)（鍍(du)(du)層(ceng)含鋁(lv)5%或55%），在酸性環境下的(de)防(fang)腐(fu)(fu)效果由于熱(re)浸(jin)鍍(du)(du)鋅鋼(gang)(gang)板(ban)(ban)(ban)(ban)(ban)，但(dan)在混(hun)(hun)凝(ning)土的(de)堿性條件(jian)下，鍍(du)(du)鋁(lv)鋅的(de)防(fang)腐(fu)(fu)蝕性能低(di)于熱(re)浸(jin)鍍(du)(du)鋅鋼(gang)(gang)板(ban)(ban)(ban)(ban)(ban)，且(qie)鋁(lv)會和混(hun)(hun)凝(ning)土發生反應(ying)，并(bing)降低(di)混(hun)(hun)凝(ning)土與鋼(gang)(gang)板(ban)(ban)(ban)(ban)(ban)的(de)粘結(jie)性能。因此參(can)考國(guo)外規范，及國(guo)內外工程，行家(jia)壓型鋼(gang)(gang)板(ban)(ban)(ban)(ban)(ban)不建議使用鍍(du)(du)鋁(lv)鋅鋼(gang)(gang)板(ban)(ban)(ban)(ban)(ban)。
