重慶樓(lou)承板(ban)(ban)(ban)的(de)鍍鋅(xin)(xin)量沒有一個(ge)具體的(de)標準(zhun)，制作(zuo)壓型(xing)(xing)鋼板(ban)(ban)(ban)的(de)冷軋鋼卷須連續(xu)熱(re)浸鍍鋅(xin)(xin)（或鍍鋁(lv)(lv)鋅(xin)(xin)），鍍（鋁(lv)(lv)）鋅(xin)(xin)量視設(she)計要求(qiu)而定。樓(lou)承板(ban)(ban)(ban)用壓型(xing)(xing)鋼板(ban)(ban)(ban)宜選(xuan)擇熱(re)浸鍍鋅(xin)(xin)鋼板(ban)(ban)(ban)。不允許使(shi)用電鍍鋅(xin)(xin)鋼板(ban)(ban)(ban)，電鍍鋅(xin)(xin)鋼板(ban)(ban)(ban)僅(jin)在基材表面形成保護層，防(fang)腐能(neng)力有限。目前市(shi)場上有鍍鋅(xin)(xin)鋼板(ban)(ban)(ban)（鍍層含鋁(lv)(lv)5%或55%），在酸性(xing)環(huan)境下的(de)防(fang)腐效果由(you)于(yu)(yu)熱(re)浸鍍鋅(xin)(xin)鋼板(ban)(ban)(ban)，但在混(hun)凝(ning)土的(de)堿性(xing)條件下，鍍鋁(lv)(lv)鋅(xin)(xin)的(de)防(fang)腐蝕性(xing)能(neng)低(di)于(yu)(yu)熱(re)浸鍍鋅(xin)(xin)鋼板(ban)(ban)(ban)，且(qie)鋁(lv)(lv)會和混(hun)凝(ning)土發生反(fan)應，并降低(di)混(hun)凝(ning)土與(yu)鋼板(ban)(ban)(ban)的(de)粘結性(xing)能(neng)。因此(ci)參考國外規范，及國內外工程，行家壓型(xing)(xing)鋼板(ban)(ban)(ban)不建議使(shi)用鍍鋁(lv)(lv)鋅(xin)(xin)鋼板(ban)(ban)(ban)。

熱鍍鋅鋼管廠家樓承板在建筑當中已經被廣泛的使用，對于此種設備的標準化和工廠化的程度已經是越來越高了，那么它們現在已經發展成為了產業化的趨勢，那么在未來對于桁架樓承板來說，應該有好的市場發展前景，現在我們就要來說一說鋼筋桁架樓承板在使用過程當中如何進行防腐的操作。如今對于我們國家的建筑鋼結構來說，它們的發展趨勢是特別好的，它們也大大的推動了我們國家的冶金行業的發展，現在對于建筑行業和冶金行業已經緊緊的聯系在一起了。眉山熱鍍鋅鋼管對于未來(lai)我們的鋼筋桁架樓承板將會處(chu)于一個新的發展時期。
