閬中攀華鍍鋅卷樓承板鍍鋅首要起到防腐的效果，按標準組合樓板與非組合樓板壓型鋼板應選用熱鍍鋅，不該選用電鍍鋅鋼板，其雙面鍍鋅層總含量要滿足在使用期間不致銹損的要求。當作為非組合樓承板時，鍍鋅層含量可選用較低值;當為組合樓承板時，鍍鋅層含量不該小于150g/m2。當為組合樓板且使用環境條件較為惡劣時，鍍鋅層含量應選用上限值或更高值。更高的鍍鋅要求，如雙面鍍鋅量為300g/m2、350g/m2或鍍鋁鋅(5%鋁)275g/m2、300g/m2等，較高的鍍層量使組合樓板有更長耐久性，同等量的鍍鋁鋅的防銹蝕才能大約兩倍于一般熱鍍鋅。鍍鋅卷價格鍍(du)鋅量也不是越厚越好，當鍍(du)鋅量較(jiao)厚時(shi)，抗剪連接(jie)件栓(shuan)釘的(de)焊接(jie)質量就很(hen)難(nan)保證，焊接(jie)時(shi)，宜選用局(ju)部除鋅處理措施。

鍍鋅(xin)(xin)(xin)(xin)鋼(gang)板(ban)(ban)(ban)(ban)(ban)是為(wei)防止鋼(gang)板(ban)(ban)(ban)(ban)(ban)表面(mian)遭受腐蝕(shi)，延(yan)長其使用壽命，在鋼(gang)板(ban)(ban)(ban)(ban)(ban)表面(mian)涂以(yi)一層金屬鋅(xin)(xin)(xin)(xin)，這(zhe)種涂鋅(xin)(xin)(xin)(xin)的(de)(de)(de)薄(bo)鋼(gang)板(ban)(ban)(ban)(ban)(ban)稱為(wei)鍍鋅(xin)(xin)(xin)(xin)板(ban)(ban)(ban)(ban)(ban)。按生(sheng)(sheng)產及加(jia)工方法可分為(wei)以(yi)下幾類：熱(re)(re)浸鍍鋅(xin)(xin)(xin)(xin)鋼(gang)板(ban)(ban)(ban)(ban)(ban)。將薄(bo)鋼(gang)板(ban)(ban)(ban)(ban)(ban)浸入熔(rong) 微商貨源解的(de)(de)(de)鋅(xin)(xin)(xin)(xin)槽(cao)中，使其表面(mian)粘附一層鋅(xin)(xin)(xin)(xin)的(de)(de)(de)薄(bo)鋼(gang)板(ban)(ban)(ban)(ban)(ban)。目(mu)前主(zhu)要采用連續鍍鋅(xin)(xin)(xin)(xin)工藝(yi)生(sheng)(sheng)產，即把成卷(juan)的(de)(de)(de)鋼(gang)板(ban)(ban)(ban)(ban)(ban)連續浸在熔(rong)解有鋅(xin)(xin)(xin)(xin)的(de)(de)(de)鍍槽(cao)中制成鍍鋅(xin)(xin)(xin)(xin)鋼(gang)板(ban)(ban)(ban)(ban)(ban)；合金化鍍鋅(xin)(xin)(xin)(xin)鋼(gang)板(ban)(ban)(ban)(ban)(ban)。這(zhe)種鋼(gang)板(ban)(ban)(ban)(ban)(ban)也是用熱(re)(re)浸法制造，但在出槽(cao)后，立即把它加(jia)熱(re)(re)到(dao)５００℃左右，使其生(sheng)(sheng)成鋅(xin)(xin)(xin)(xin)和鐵的(de)(de)(de)合金被膜。這(zhe)種鍍鋅(xin)(xin)(xin)(xin)板(ban)(ban)(ban)(ban)(ban)具有良(liang)好(hao)的(de)(de)(de)涂料(liao)的(de)(de)(de)密著(zhu)性和焊接性。

鍍(du)(du)鋅(xin)鋼板(ban)(ban)(ban)按用(yong)(yong)(yong)(yong)(yong)途又可分(fen)為一般(ban)用(yong)(yong)(yong)(yong)(yong)、屋頂(ding)用(yong)(yong)(yong)(yong)(yong)、建(jian)(jian)筑外側板(ban)(ban)(ban)用(yong)(yong)(yong)(yong)(yong)、結(jie)構用(yong)(yong)(yong)(yong)(yong)、瓦壟板(ban)(ban)(ban)用(yong)(yong)(yong)(yong)(yong)、拉伸(shen)用(yong)(yong)(yong)(yong)(yong)和深沖(chong)用(yong)(yong)(yong)(yong)(yong)等鍍(du)(du)鋅(xin)鋼板(ban)(ban)(ban)。熱鍍(du)(du)鋅(xin)板(ban)(ban)(ban)主要應(ying)用(yong)(yong)(yong)(yong)(yong)于建(jian)(jian)筑外用(yong)(yong)(yong)(yong)(yong)，建(jian)(jian)筑內用(yong)(yong)(yong)(yong)(yong)，民用(yong)(yong)(yong)(yong)(yong)，門窗，家具，機械(xie)，電子(zi)及家用(yong)(yong)(yong)(yong)(yong)電器(qi)等領域。也有(you)機箱用(yong)(yong)(yong)(yong)(yong)這個，不(bu)過熱鍍(du)(du)鋅(xin)板(ban)(ban)(ban)不(bu)放輻射的(de)。空調，冰箱，微波(bo)爐及其類似家電背面的(de)那個板(ban)(ban)(ban)就是熱鍍(du)(du)鋅(xin)板(ban)(ban)(ban)。鍍(du)(du)鋅(xin)層(ceng)(ceng)通過鈍(dun)化(hua)處理，可減少(shao)潮(chao)溫貯(zhu)運條件下產生(sheng)折銹蝕(shi)(白銹) 。但這種化(hua)學處理的(de)防腐(fu)蝕(shi)性(xing)能是有(you)限的(de)，而且，妨(fang)礙大多數涂料的(de)附著性(xing)。這種處理一般(ban)不(bu)用(yong)(yong)(yong)(yong)(yong)在鋅(xin)鐵合金鍍(du)(du)層(ceng)(ceng)，除光整表面外，作為常規，生(sheng)產廠對其他類型的(de)鍍(du)(du)鋅(xin)層(ceng)(ceng)均進行鈍(dun)化(hua)處理。
