赤水C型鋼重慶樓承板的鍍鋅量沒有一個具體的標準，制作壓型鋼板的冷軋鋼卷須連續熱浸鍍鋅（或鍍鋁鋅），鍍（鋁）鋅量視設計要求而定。C型鋼價格樓承板(ban)(ban)(ban)(ban)(ban)用壓(ya)型鋼板(ban)(ban)(ban)(ban)(ban)宜選擇熱(re)浸鍍(du)(du)(du)鋅鋼板(ban)(ban)(ban)(ban)(ban)。不允許使用電(dian)鍍(du)(du)(du)鋅鋼板(ban)(ban)(ban)(ban)(ban)，電(dian)鍍(du)(du)(du)鋅鋼板(ban)(ban)(ban)(ban)(ban)僅(jin)在基材表(biao)面形成保護層，防(fang)腐能力有(you)限。目前(qian)市場上有(you)鍍(du)(du)(du)鋅鋼板(ban)(ban)(ban)(ban)(ban)（鍍(du)(du)(du)層含鋁(lv)5%或55%），在酸(suan)性環境下的(de)(de)(de)防(fang)腐效果由于熱(re)浸鍍(du)(du)(du)鋅鋼板(ban)(ban)(ban)(ban)(ban)，但在混(hun)(hun)(hun)凝土(tu)的(de)(de)(de)堿性條件下，鍍(du)(du)(du)鋁(lv)鋅的(de)(de)(de)防(fang)腐蝕性能低于熱(re)浸鍍(du)(du)(du)鋅鋼板(ban)(ban)(ban)(ban)(ban)，且鋁(lv)會和混(hun)(hun)(hun)凝土(tu)發生(sheng)反(fan)應，并降低混(hun)(hun)(hun)凝土(tu)與鋼板(ban)(ban)(ban)(ban)(ban)的(de)(de)(de)粘結(jie)性能。因此參(can)考國(guo)外(wai)規范(fan)，及國(guo)內(nei)外(wai)工程，行(xing)家壓(ya)型鋼板(ban)(ban)(ban)(ban)(ban)不建議使用鍍(du)(du)(du)鋁(lv)鋅鋼板(ban)(ban)(ban)(ban)(ban)。
