鍍鋅帶鋼批發熱鍍鋅板和電鍍鋅板在鍍鋅量上有很大的差別，就像山東彩涂卷）。熱鍍鋅的鍍鋅量不可能太小，一般較小為雙面50～60g／m2，較大可達600g／m2。巴中鍍鋅帶鋼電鍍(du)鋅(xin)(xin)板的(de)(de)鍍(du)鋅(xin)(xin)層(ceng)可以(yi)很薄，較(jiao)小達15g／m2，但(dan)要求鍍(du)層(ceng)較(jiao)厚的(de)(de)話則生(sheng)產線速度很慢，不適(shi)應(ying)現代化機組的(de)(de)工(gong)藝特(te)點(dian)，一(yi)(yi)般較(jiao)大(da)(da)為lO0g／m2左(zuo)右。正因(yin)為如此(ci)，電鍍(du)鋅(xin)(xin)板的(de)(de)生(sheng)產受到很大(da)(da)的(de)(de)限制。工(gong)一(yi)(yi)般電鍍(du)鋅(xin)(xin)比較(jiao)多，適(shi)用于小部(bu)(bu)(bu)件(jian)；熱鍍(du)鋅(xin)(xin)一(yi)(yi)般用于電力設備和構件(jian)，適(shi)用于大(da)(da)的(de)(de)部(bu)(bu)(bu)件(jian)和設備。當(dang)然他們的(de)(de)價格也相對(dui)便宜一(yi)(yi)些(xie)。建設部(bu)(bu)(bu)已(yi)正式(shi)下文，淘(tao)汰(tai)技術落后的(de)(de)冷鍍(du)鋅(xin)(xin)管，不準用冷鍍(du)鋅(xin)(xin)管作水、煤氣管。

鍍鋅(xin)(xin)鋼(gang)(gang)板(ban)(ban)(ban)(ban)是為(wei)防(fang)止鋼(gang)(gang)板(ban)(ban)(ban)(ban)表面(mian)遭受腐蝕，延長其(qi)使用(yong)壽命，在(zai)鋼(gang)(gang)板(ban)(ban)(ban)(ban)表面(mian)涂(tu)以一層(ceng)金屬鋅(xin)(xin)，這(zhe)(zhe)種涂(tu)鋅(xin)(xin)的(de)(de)(de)(de)(de)(de)(de)薄(bo)鋼(gang)(gang)板(ban)(ban)(ban)(ban)稱為(wei)鍍鋅(xin)(xin)板(ban)(ban)(ban)(ban)。鋼(gang)(gang)板(ban)(ban)(ban)(ban)也是用(yong)熱(re)浸(jin)法(fa)制(zhi)造，但在(zai)出槽后，立即把(ba)它(ta)加熱(re)到500℃左右，使其(qi)生成(cheng)(cheng)(cheng)鋅(xin)(xin)和(he)鐵的(de)(de)(de)(de)(de)(de)(de)合金被(bei)膜。這(zhe)(zhe)種鍍鋅(xin)(xin)卷具有良(liang)好的(de)(de)(de)(de)(de)(de)(de)涂(tu)料的(de)(de)(de)(de)(de)(de)(de)密著性(xing)和(he)焊接(jie)性(xing)。合金化鍍鋅(xin)(xin)鋼(gang)(gang)板(ban)(ban)(ban)(ban)。這(zhe)(zhe)種鋼(gang)(gang)板(ban)(ban)(ban)(ban)也是用(yong)熱(re)浸(jin)法(fa)制(zhi)造，但在(zai)出槽后，立即把(ba)它(ta)加熱(re)到500℃左右，使其(qi)生成(cheng)(cheng)(cheng)鋅(xin)(xin)和(he)鐵的(de)(de)(de)(de)(de)(de)(de)合金被(bei)膜。這(zhe)(zhe)種鍍鋅(xin)(xin)板(ban)(ban)(ban)(ban)具有良(liang)好的(de)(de)(de)(de)(de)(de)(de)涂(tu)料的(de)(de)(de)(de)(de)(de)(de)密著性(xing)和(he)焊接(jie)性(xing)。熱(re)浸(jin)鍍鋅(xin)(xin)鋼(gang)(gang)板(ban)(ban)(ban)(ban)。將薄(bo)鋼(gang)(gang)板(ban)(ban)(ban)(ban)浸(jin)入熔(rong)解的(de)(de)(de)(de)(de)(de)(de)鋅(xin)(xin)槽中，使其(qi)表面(mian)粘附一層(ceng)鋅(xin)(xin)的(de)(de)(de)(de)(de)(de)(de)薄(bo)鋼(gang)(gang)板(ban)(ban)(ban)(ban)。目前主(zhu)要采用(yong)連續鍍鋅(xin)(xin)工(gong)藝(yi)生產，即把(ba)成(cheng)(cheng)(cheng)卷的(de)(de)(de)(de)(de)(de)(de)鋼(gang)(gang)板(ban)(ban)(ban)(ban)連續浸(jin)在(zai)熔(rong)解有鋅(xin)(xin)的(de)(de)(de)(de)(de)(de)(de)鍍槽中制(zhi)成(cheng)(cheng)(cheng)鍍鋅(xin)(xin)鋼(gang)(gang)板(ban)(ban)(ban)(ban)。合金、復合鍍鋅(xin)(xin)鋼(gang)(gang)板(ban)(ban)(ban)(ban)。它(ta)是用(yong)鋅(xin)(xin)和(he)其(qi)他(ta)金屬如鉛、鋅(xin)(xin)制(zhi)成(cheng)(cheng)(cheng)合金乃至復合鍍成(cheng)(cheng)(cheng)的(de)(de)(de)(de)(de)(de)(de)鋼(gang)(gang)板(ban)(ban)(ban)(ban)。這(zhe)(zhe)種鋼(gang)(gang)板(ban)(ban)(ban)(ban)既(ji)具有防(fang)銹(xiu)性(xing)能，又有良(liang)好的(de)(de)(de)(de)(de)(de)(de)涂(tu)裝性(xing)能。

重慶樓承(cheng)板(ban)(ban)(ban)的(de)鍍(du)鋅(xin)(xin)(xin)量(liang)沒有一個具體的(de)標(biao)準，制作壓型(xing)(xing)鋼(gang)(gang)板(ban)(ban)(ban)的(de)冷(leng)軋鋼(gang)(gang)卷須(xu)連續熱浸鍍(du)鋅(xin)(xin)(xin)（或鍍(du)鋁(lv)(lv)鋅(xin)(xin)(xin)），鍍(du)（鋁(lv)(lv)）鋅(xin)(xin)(xin)量(liang)視(shi)設計要求而定(ding)。樓承(cheng)板(ban)(ban)(ban)用壓型(xing)(xing)鋼(gang)(gang)板(ban)(ban)(ban)宜選擇熱浸鍍(du)鋅(xin)(xin)(xin)鋼(gang)(gang)板(ban)(ban)(ban)。不允許使(shi)(shi)用電鍍(du)鋅(xin)(xin)(xin)鋼(gang)(gang)板(ban)(ban)(ban)，電鍍(du)鋅(xin)(xin)(xin)鋼(gang)(gang)板(ban)(ban)(ban)僅在(zai)基材(cai)表面形成(cheng)保護層，防(fang)腐(fu)能力有限(xian)。目前市(shi)場上有鍍(du)鋅(xin)(xin)(xin)鋼(gang)(gang)板(ban)(ban)(ban)（鍍(du)層含鋁(lv)(lv)5%或55%），在(zai)酸性(xing)(xing)環境下(xia)的(de)防(fang)腐(fu)效果(guo)由于熱浸鍍(du)鋅(xin)(xin)(xin)鋼(gang)(gang)板(ban)(ban)(ban)，但在(zai)混凝土的(de)堿性(xing)(xing)條件下(xia)，鍍(du)鋁(lv)(lv)鋅(xin)(xin)(xin)的(de)防(fang)腐(fu)蝕(shi)性(xing)(xing)能低于熱浸鍍(du)鋅(xin)(xin)(xin)鋼(gang)(gang)板(ban)(ban)(ban)，且(qie)鋁(lv)(lv)會和混凝土發生反應，并降低混凝土與鋼(gang)(gang)板(ban)(ban)(ban)的(de)粘結(jie)性(xing)(xing)能。因此參考國外規范，及國內外工(gong)程，行家壓型(xing)(xing)鋼(gang)(gang)板(ban)(ban)(ban)不建議使(shi)(shi)用鍍(du)鋁(lv)(lv)鋅(xin)(xin)(xin)鋼(gang)(gang)板(ban)(ban)(ban)。
