鍍(du)(du)鋅(xin)(xin)(xin)鋼(gang)板(ban)(ban)是為(wei)防(fang)止(zhi)鋼(gang)板(ban)(ban)表(biao)面遭受腐蝕，延長其使用壽命(ming)，在(zai)鋼(gang)板(ban)(ban)表(biao)面涂以一(yi)層(ceng)金(jin)屬(shu)鋅(xin)(xin)(xin)，這(zhe)(zhe)種涂鋅(xin)(xin)(xin)的(de)(de)薄(bo)鋼(gang)板(ban)(ban)稱為(wei)鍍(du)(du)鋅(xin)(xin)(xin)板(ban)(ban)。按生產及加(jia)工方法可分為(wei)以下幾類：熱浸(jin)鍍(du)(du)鋅(xin)(xin)(xin)鋼(gang)板(ban)(ban)。將(jiang)薄(bo)鋼(gang)板(ban)(ban)浸(jin)入(ru)熔 微商(shang)貨(huo)源解(jie)的(de)(de)鋅(xin)(xin)(xin)槽(cao)中(zhong)，使其表(biao)面粘附一(yi)層(ceng)鋅(xin)(xin)(xin)的(de)(de)薄(bo)鋼(gang)板(ban)(ban)。目前主要(yao)采用連(lian)續鍍(du)(du)鋅(xin)(xin)(xin)工藝生產，即把成(cheng)卷的(de)(de)鋼(gang)板(ban)(ban)連(lian)續浸(jin)在(zai)熔解(jie)有(you)鋅(xin)(xin)(xin)的(de)(de)鍍(du)(du)槽(cao)中(zhong)制(zhi)(zhi)成(cheng)鍍(du)(du)鋅(xin)(xin)(xin)鋼(gang)板(ban)(ban)；合金(jin)化鍍(du)(du)鋅(xin)(xin)(xin)鋼(gang)板(ban)(ban)。這(zhe)(zhe)種鋼(gang)板(ban)(ban)也是用熱浸(jin)法制(zhi)(zhi)造，但在(zai)出(chu)槽(cao)后(hou)，立即把它加(jia)熱到５００℃左右，使其生成(cheng)鋅(xin)(xin)(xin)和(he)鐵(tie)的(de)(de)合金(jin)被膜。這(zhe)(zhe)種鍍(du)(du)鋅(xin)(xin)(xin)板(ban)(ban)具(ju)有(you)良好的(de)(de)涂料的(de)(de)密著性(xing)和(he)焊接(jie)性(xing)。

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)用壓型鋼(gang)(gang)(gang)板(ban)宜選擇熱浸鍍(du)鋅(xin)鋼(gang)(gang)(gang)板(ban)。不允許使用電鍍(du)鋅(xin)鋼(gang)(gang)(gang)板(ban)，電鍍(du)鋅(xin)鋼(gang)(gang)(gang)板(ban)僅(jin)在(zai)基材(cai)表面形(xing)成保護(hu)層(ceng)，防(fang)腐能力有限。目前市場上有鍍(du)鋅(xin)鋼(gang)(gang)(gang)板(ban)（鍍(du)層(ceng)含鋁5%或55%），在(zai)酸性(xing)(xing)環境(jing)下的(de)防(fang)腐效果由于(yu)熱浸鍍(du)鋅(xin)鋼(gang)(gang)(gang)板(ban)，但(dan)在(zai)混(hun)(hun)凝土(tu)的(de)堿(jian)性(xing)(xing)條件下，鍍(du)鋁鋅(xin)的(de)防(fang)腐蝕性(xing)(xing)能低于(yu)熱浸鍍(du)鋅(xin)鋼(gang)(gang)(gang)板(ban)，且鋁會和混(hun)(hun)凝土(tu)發(fa)生反應，并(bing)降(jiang)低混(hun)(hun)凝土(tu)與(yu)鋼(gang)(gang)(gang)板(ban)的(de)粘結性(xing)(xing)能。因此參(can)考(kao)國外規范，及國內外工程(cheng)，行(xing)家壓型鋼(gang)(gang)(gang)板(ban)不建議(yi)使用鍍(du)鋁鋅(xin)鋼(gang)(gang)(gang)板(ban)。

鍍(du)(du)(du)鋅(xin)(xin)(xin)鋼(gang)板(ban)(ban)按用(yong)(yong)(yong)(yong)途又可(ke)分為(wei)一般(ban)用(yong)(yong)(yong)(yong)、屋頂用(yong)(yong)(yong)(yong)、建(jian)筑(zhu)(zhu)外側(ce)板(ban)(ban)用(yong)(yong)(yong)(yong)、結(jie)構用(yong)(yong)(yong)(yong)、瓦(wa)壟板(ban)(ban)用(yong)(yong)(yong)(yong)、拉(la)伸(shen)用(yong)(yong)(yong)(yong)和(he)深沖用(yong)(yong)(yong)(yong)等鍍(du)(du)(du)鋅(xin)(xin)(xin)鋼(gang)板(ban)(ban)。熱鍍(du)(du)(du)鋅(xin)(xin)(xin)板(ban)(ban)主要(yao)應(ying)用(yong)(yong)(yong)(yong)于建(jian)筑(zhu)(zhu)外用(yong)(yong)(yong)(yong)，建(jian)筑(zhu)(zhu)內(nei)用(yong)(yong)(yong)(yong)，民用(yong)(yong)(yong)(yong)，門窗，家具(ju)，機械(xie)，電(dian)子(zi)及(ji)家用(yong)(yong)(yong)(yong)電(dian)器等領域(yu)。也有(you)(you)機箱用(yong)(yong)(yong)(yong)這個(ge)，不(bu)過熱鍍(du)(du)(du)鋅(xin)(xin)(xin)板(ban)(ban)不(bu)放輻射的(de)。空調，冰箱，微波爐及(ji)其(qi)(qi)類似家電(dian)背面的(de)那個(ge)板(ban)(ban)就是熱鍍(du)(du)(du)鋅(xin)(xin)(xin)板(ban)(ban)。鍍(du)(du)(du)鋅(xin)(xin)(xin)層(ceng)通過鈍化(hua)處(chu)理，可(ke)減少潮溫貯運條(tiao)件下(xia)產生折銹蝕(白銹) 。但這種(zhong)(zhong)化(hua)學處(chu)理的(de)防腐蝕性能是有(you)(you)限的(de)，而(er)且，妨(fang)礙(ai)大多(duo)數涂(tu)料(liao)的(de)附(fu)著性。這種(zhong)(zhong)處(chu)理一般(ban)不(bu)用(yong)(yong)(yong)(yong)在鋅(xin)(xin)(xin)鐵合金鍍(du)(du)(du)層(ceng)，除光整(zheng)表面外，作為(wei)常規，生產廠(chang)對其(qi)(qi)他(ta)類型的(de)鍍(du)(du)(du)鋅(xin)(xin)(xin)層(ceng)均進行(xing)鈍化(hua)處(chu)理。
