樓(lou)承板(ban)(ban)(ban)鍍(du)(du)鋅(xin)(xin)(xin)(xin)首要(yao)起到防腐的(de)效果，按標準(zhun)組(zu)合(he)樓(lou)板(ban)(ban)(ban)與非(fei)組(zu)合(he)樓(lou)板(ban)(ban)(ban)壓型鋼板(ban)(ban)(ban)應選(xuan)(xuan)用熱鍍(du)(du)鋅(xin)(xin)(xin)(xin)，不該(gai)選(xuan)(xuan)用電(dian)鍍(du)(du)鋅(xin)(xin)(xin)(xin)鋼板(ban)(ban)(ban)，其雙面鍍(du)(du)鋅(xin)(xin)(xin)(xin)層(ceng)(ceng)總含量(liang)(liang)要(yao)滿足在(zai)使用期間不致銹(xiu)損的(de)要(yao)求。當作(zuo)為(wei)(wei)(wei)非(fei)組(zu)合(he)樓(lou)承板(ban)(ban)(ban)時，鍍(du)(du)鋅(xin)(xin)(xin)(xin)層(ceng)(ceng)含量(liang)(liang)可選(xuan)(xuan)用較(jiao)(jiao)低值;當為(wei)(wei)(wei)組(zu)合(he)樓(lou)承板(ban)(ban)(ban)時，鍍(du)(du)鋅(xin)(xin)(xin)(xin)層(ceng)(ceng)含量(liang)(liang)不該(gai)小于(yu)150g/m2。當為(wei)(wei)(wei)組(zu)合(he)樓(lou)板(ban)(ban)(ban)且使用環境(jing)條件(jian)較(jiao)(jiao)為(wei)(wei)(wei)惡劣(lie)時，鍍(du)(du)鋅(xin)(xin)(xin)(xin)層(ceng)(ceng)含量(liang)(liang)應選(xuan)(xuan)用上限值或(huo)更(geng)高值。更(geng)高的(de)鍍(du)(du)鋅(xin)(xin)(xin)(xin)要(yao)求，如雙面鍍(du)(du)鋅(xin)(xin)(xin)(xin)量(liang)(liang)為(wei)(wei)(wei)300g/m2、350g/m2或(huo)鍍(du)(du)鋁鋅(xin)(xin)(xin)(xin)(5%鋁)275g/m2、300g/m2等，較(jiao)(jiao)高的(de)鍍(du)(du)層(ceng)(ceng)量(liang)(liang)使組(zu)合(he)樓(lou)板(ban)(ban)(ban)有(you)更(geng)長耐久性，同等量(liang)(liang)的(de)鍍(du)(du)鋁鋅(xin)(xin)(xin)(xin)的(de)防銹(xiu)蝕才能大約兩倍于(yu)一般熱鍍(du)(du)鋅(xin)(xin)(xin)(xin)。鍍(du)(du)鋅(xin)(xin)(xin)(xin)量(liang)(liang)也不是越(yue)厚(hou)越(yue)好，當鍍(du)(du)鋅(xin)(xin)(xin)(xin)量(liang)(liang)較(jiao)(jiao)厚(hou)時，抗剪(jian)連(lian)接件(jian)栓釘的(de)焊(han)接質量(liang)(liang)就(jiu)很難保證，焊(han)接時，宜選(xuan)(xuan)用局部(bu)除鋅(xin)(xin)(xin)(xin)處理(li)措(cuo)施。

鍍(du)鋅(xin)(xin)(xin)(xin)鋼(gang)板(ban)(ban)(ban)是為防止鋼(gang)板(ban)(ban)(ban)表(biao)面遭受腐蝕，延長(chang)其(qi)(qi)使用壽命，在(zai)鋼(gang)板(ban)(ban)(ban)表(biao)面涂(tu)以(yi)一(yi)層(ceng)金(jin)屬鋅(xin)(xin)(xin)(xin)，這種涂(tu)鋅(xin)(xin)(xin)(xin)的(de)薄(bo)鋼(gang)板(ban)(ban)(ban)稱為鍍(du)鋅(xin)(xin)(xin)(xin)板(ban)(ban)(ban)。按生(sheng)產(chan)及加(jia)工方法可分為以(yi)下幾(ji)類：熱(re)浸(jin)鍍(du)鋅(xin)(xin)(xin)(xin)鋼(gang)板(ban)(ban)(ban)。將薄(bo)鋼(gang)板(ban)(ban)(ban)浸(jin)入熔 微(wei)商(shang)貨源解(jie)的(de)鋅(xin)(xin)(xin)(xin)槽(cao)中(zhong)，使其(qi)(qi)表(biao)面粘附一(yi)層(ceng)鋅(xin)(xin)(xin)(xin)的(de)薄(bo)鋼(gang)板(ban)(ban)(ban)。目前主要采用連續鍍(du)鋅(xin)(xin)(xin)(xin)工藝生(sheng)產(chan)，即把成卷的(de)鋼(gang)板(ban)(ban)(ban)連續浸(jin)在(zai)熔解(jie)有鋅(xin)(xin)(xin)(xin)的(de)鍍(du)槽(cao)中(zhong)制成鍍(du)鋅(xin)(xin)(xin)(xin)鋼(gang)板(ban)(ban)(ban)；合(he)金(jin)化鍍(du)鋅(xin)(xin)(xin)(xin)鋼(gang)板(ban)(ban)(ban)。這種鋼(gang)板(ban)(ban)(ban)也是用熱(re)浸(jin)法制造，但在(zai)出槽(cao)后，立(li)即把它加(jia)熱(re)到５００℃左(zuo)右，使其(qi)(qi)生(sheng)成鋅(xin)(xin)(xin)(xin)和鐵的(de)合(he)金(jin)被膜。這種鍍(du)鋅(xin)(xin)(xin)(xin)板(ban)(ban)(ban)具有良(liang)好(hao)的(de)涂(tu)料(liao)的(de)密著性(xing)(xing)和焊接性(xing)(xing)。

C型鋼廠家鍍鋅卷分熱鍍鋅和電鍍鋅兩種，熱鍍鋅鍍鋅層厚，具有鍍層均勻，附著力強，使用壽命長等優點。萬州C型鋼電鍍鋅成本(ben)低，表(biao)面(mian)不是很(hen)光滑(hua)，其(qi)本(ben)身的(de)耐腐(fu)蝕(shi)(shi)性比熱鍍鋅管相差很(hen)多。提起鍍鋅管，可能沒接(jie)觸過建材的(de)朋友并不了解。從1935年建立一條連續涂(tu)層(ceng)鋼(gang)板(ban)線開始，彩涂(tu)板(ban)得到(dao)了廣泛(fan)應用，目(mu)前(qian)彩涂(tu)板(ban)的(de)品種(zhong)繁多，大約超過600種(zhong)，彩涂(tu)板(ban)兼(jian)有(you)(you)機聚合物(wu)與(yu)鋼(gang)板(ban)兩者的(de)優點，既(ji)有(you)(you)有(you)(you)機聚合物(wu)的(de)良(liang)好著(zhu)色性、成型性、耐蝕(shi)(shi)性、裝飾性、又有(you)(you)鋼(gang)板(ban)的(de)高強度和易加工性，能很(hen)容(rong)易地進行沖壓裁剪、彎曲、深沖等加工。

鍍(du)(du)(du)(du)鋅(xin)(xin)方(fang)管是(shi)一種具(ju)以熱軋或(huo)冷(leng)軋鍍(du)(du)(du)(du)鋅(xin)(xin)帶鋼或(huo)鍍(du)(du)(du)(du)鋅(xin)(xin)卷(juan)(juan)板為(wei)坯料(liao)經(jing)冷(leng)彎曲(qu)加工(gong)成(cheng)(cheng)型(xing)后(hou)再(zai)經(jing)高頻(pin)焊接(jie)制成(cheng)(cheng)的(de)(de)方(fang)形截面形狀(zhuang)尺寸的(de)(de)空(kong)心方(fang)形的(de)(de)截面型(xing)鋼鋼管；鍍(du)(du)(du)(du)鋅(xin)(xin)卷(juan)(juan)或(huo)將事先做(zuo)好的(de)(de)冷(leng)彎空(kong)心型(xing)鋼管再(zai)經(jing)熱浸鍍(du)(du)(du)(du)鋅(xin)(xin)加工(gong)而成(cheng)(cheng)的(de)(de)鍍(du)(du)(du)(du)鋅(xin)(xin)方(fang)矩管。鍍(du)(du)(du)(du)鋅(xin)(xin)量(liang)(liang)是(shi)表示鍍(du)(du)(du)(du)鋅(xin)(xin)板鋅(xin)(xin)層(ceng)厚度的(de)(de)一個普遍采用的(de)(de)有效方(fang)法。鍍(du)(du)(du)(du)鋅(xin)(xin)量(liang)(liang)的(de)(de)單位為(wei)g/m2。鍍(du)(du)(du)(du)鋅(xin)(xin)層(ceng)通過鈍化處(chu)(chu)理，可減少潮溫貯運條(tiao)件下產生(sheng)折銹蝕(shi)(白銹) 。但這種化學處(chu)(chu)理的(de)(de)防腐(fu)蝕(shi)性能是(shi)有限(xian)的(de)(de)，而且，妨礙大多數涂料(liao)的(de)(de)附著性。這種處(chu)(chu)理一般不(bu)用在鋅(xin)(xin)鐵合金鍍(du)(du)(du)(du)層(ceng)，除光整表面外(wai)，作(zuo)為(wei)常規(gui)，生(sheng)產廠對其(qi)他(ta)類型(xing)的(de)(de)鍍(du)(du)(du)(du)鋅(xin)(xin)層(ceng)均(jun)進行鈍化處(chu)(chu)理。
