樓(lou)(lou)承板(ban)(ban)(ban)鍍(du)(du)(du)(du)(du)鋅(xin)(xin)(xin)首要起到防(fang)腐的效果，按(an)標準(zhun)組(zu)合(he)(he)樓(lou)(lou)板(ban)(ban)(ban)與非組(zu)合(he)(he)樓(lou)(lou)板(ban)(ban)(ban)壓型鋼板(ban)(ban)(ban)應選(xuan)用熱鍍(du)(du)(du)(du)(du)鋅(xin)(xin)(xin)，不(bu)(bu)該選(xuan)用電(dian)鍍(du)(du)(du)(du)(du)鋅(xin)(xin)(xin)鋼板(ban)(ban)(ban)，其雙面鍍(du)(du)(du)(du)(du)鋅(xin)(xin)(xin)層(ceng)總含量(liang)(liang)要滿足在使(shi)用期間不(bu)(bu)致銹損的要求。當作為(wei)非組(zu)合(he)(he)樓(lou)(lou)承板(ban)(ban)(ban)時(shi)(shi)，鍍(du)(du)(du)(du)(du)鋅(xin)(xin)(xin)層(ceng)含量(liang)(liang)可選(xuan)用較(jiao)低(di)值(zhi)(zhi);當為(wei)組(zu)合(he)(he)樓(lou)(lou)承板(ban)(ban)(ban)時(shi)(shi)，鍍(du)(du)(du)(du)(du)鋅(xin)(xin)(xin)層(ceng)含量(liang)(liang)不(bu)(bu)該小于(yu)150g/m2。當為(wei)組(zu)合(he)(he)樓(lou)(lou)板(ban)(ban)(ban)且使(shi)用環境(jing)條件較(jiao)為(wei)惡劣時(shi)(shi)，鍍(du)(du)(du)(du)(du)鋅(xin)(xin)(xin)層(ceng)含量(liang)(liang)應選(xuan)用上(shang)限值(zhi)(zhi)或更高(gao)值(zhi)(zhi)。更高(gao)的鍍(du)(du)(du)(du)(du)鋅(xin)(xin)(xin)要求，如雙面鍍(du)(du)(du)(du)(du)鋅(xin)(xin)(xin)量(liang)(liang)為(wei)300g/m2、350g/m2或鍍(du)(du)(du)(du)(du)鋁鋅(xin)(xin)(xin)(5%鋁)275g/m2、300g/m2等，較(jiao)高(gao)的鍍(du)(du)(du)(du)(du)層(ceng)量(liang)(liang)使(shi)組(zu)合(he)(he)樓(lou)(lou)板(ban)(ban)(ban)有更長(chang)耐久性(xing)，同等量(liang)(liang)的鍍(du)(du)(du)(du)(du)鋁鋅(xin)(xin)(xin)的防(fang)銹蝕(shi)才能大約(yue)兩(liang)倍(bei)于(yu)一(yi)般(ban)熱鍍(du)(du)(du)(du)(du)鋅(xin)(xin)(xin)。鍍(du)(du)(du)(du)(du)鋅(xin)(xin)(xin)量(liang)(liang)也不(bu)(bu)是越(yue)厚(hou)(hou)越(yue)好，當鍍(du)(du)(du)(du)(du)鋅(xin)(xin)(xin)量(liang)(liang)較(jiao)厚(hou)(hou)時(shi)(shi)，抗剪連接件栓釘(ding)的焊接質(zhi)量(liang)(liang)就很難(nan)保證(zheng)，焊接時(shi)(shi)，宜選(xuan)用局部除鋅(xin)(xin)(xin)處(chu)理措(cuo)施(shi)。

重慶樓(lou)承板(ban)(ban)(ban)(ban)的鍍(du)(du)(du)鋅(xin)(xin)(xin)(xin)(xin)量沒有(you)一(yi)個具體(ti)的標準，制(zhi)作壓(ya)型(xing)(xing)鋼(gang)(gang)(gang)板(ban)(ban)(ban)(ban)的冷軋鋼(gang)(gang)(gang)卷須連(lian)續熱(re)浸(jin)(jin)鍍(du)(du)(du)鋅(xin)(xin)(xin)(xin)(xin)（或鍍(du)(du)(du)鋁(lv)(lv)鋅(xin)(xin)(xin)(xin)(xin)），鍍(du)(du)(du)（鋁(lv)(lv)）鋅(xin)(xin)(xin)(xin)(xin)量視設(she)計要求而定。樓(lou)承板(ban)(ban)(ban)(ban)用(yong)壓(ya)型(xing)(xing)鋼(gang)(gang)(gang)板(ban)(ban)(ban)(ban)宜選擇(ze)熱(re)浸(jin)(jin)鍍(du)(du)(du)鋅(xin)(xin)(xin)(xin)(xin)鋼(gang)(gang)(gang)板(ban)(ban)(ban)(ban)。不(bu)允許使用(yong)電鍍(du)(du)(du)鋅(xin)(xin)(xin)(xin)(xin)鋼(gang)(gang)(gang)板(ban)(ban)(ban)(ban)，電鍍(du)(du)(du)鋅(xin)(xin)(xin)(xin)(xin)鋼(gang)(gang)(gang)板(ban)(ban)(ban)(ban)僅在(zai)基材表面形(xing)成保護層，防(fang)腐能(neng)力有(you)限(xian)。目(mu)前市場上有(you)鍍(du)(du)(du)鋅(xin)(xin)(xin)(xin)(xin)鋼(gang)(gang)(gang)板(ban)(ban)(ban)(ban)（鍍(du)(du)(du)層含鋁(lv)(lv)5%或55%），在(zai)酸性環境下的防(fang)腐效果由于熱(re)浸(jin)(jin)鍍(du)(du)(du)鋅(xin)(xin)(xin)(xin)(xin)鋼(gang)(gang)(gang)板(ban)(ban)(ban)(ban)，但在(zai)混凝土(tu)的堿性條件下，鍍(du)(du)(du)鋁(lv)(lv)鋅(xin)(xin)(xin)(xin)(xin)的防(fang)腐蝕性能(neng)低于熱(re)浸(jin)(jin)鍍(du)(du)(du)鋅(xin)(xin)(xin)(xin)(xin)鋼(gang)(gang)(gang)板(ban)(ban)(ban)(ban)，且鋁(lv)(lv)會和混凝土(tu)發生反應(ying)，并降低混凝土(tu)與鋼(gang)(gang)(gang)板(ban)(ban)(ban)(ban)的粘結(jie)性能(neng)。因此參(can)考國(guo)外(wai)規范，及國(guo)內(nei)外(wai)工程，行家壓(ya)型(xing)(xing)鋼(gang)(gang)(gang)板(ban)(ban)(ban)(ban)不(bu)建議使用(yong)鍍(du)(du)(du)鋁(lv)(lv)鋅(xin)(xin)(xin)(xin)(xin)鋼(gang)(gang)(gang)板(ban)(ban)(ban)(ban)。

熱(re)鍍鋅(xin)卷(juan)(juan)板(ban)(ban)現(xian)(xian)貨(huo)(huo)消(xiao)息：熱(re)鍍鋅(xin)產品(pin)廣泛(fan)用(yong)(yong)于建筑、家電、車船、容器制造業(ye)、機電業(ye)等，幾乎(hu)涉及到衣(yi)食住行各個領域。近(jin)年來，世界鍍鋅(xin)鋼板(ban)(ban)需求量不斷增(zeng)加，產量增(zeng)長(chang)也很快(kuai)，在美、日等鋼材生產大(da)國，熱(re)鍍鋅(xin)鋼板(ban)(ban)在鋼材中所(suo)占比例已高達13%-15%。 熱(re)鍍鋅(xin)卷(juan)(juan)板(ban)(ban)現(xian)(xian)貨(huo)(huo)消(xiao)息：近(jin)來，汽(qi)車行業(ye)越(yue)來越(yue)重視材料的(de)(de)使(shi)用(yong)(yong)壽(shou)命，用(yong)(yong)涂漆冷軋(ya)鋼板(ban)(ban)已不能(neng)滿足耐腐蝕方面的(de)(de)要求。在這種情況(kuang)下，耐腐蝕性優良且(qie)成本(ben)低廉的(de)(de)熱(re)鍍鋅(xin)板(ban)(ban)開(kai)始普(pu)遍受到了汽(qi)車廠家的(de)(de)青(qing)睞。
