重慶(qing)樓承(cheng)板(ban)(ban)的(de)鍍(du)(du)(du)鋅(xin)(xin)量沒有(you)一個(ge)具體(ti)的(de)標準，制作壓(ya)(ya)型(xing)鋼(gang)(gang)板(ban)(ban)的(de)冷軋(ya)鋼(gang)(gang)卷(juan)須連(lian)續熱浸鍍(du)(du)(du)鋅(xin)(xin)（或鍍(du)(du)(du)鋁(lv)鋅(xin)(xin)），鍍(du)(du)(du)（鋁(lv)）鋅(xin)(xin)量視(shi)設計(ji)要求而定。樓承(cheng)板(ban)(ban)用壓(ya)(ya)型(xing)鋼(gang)(gang)板(ban)(ban)宜選(xuan)擇(ze)熱浸鍍(du)(du)(du)鋅(xin)(xin)鋼(gang)(gang)板(ban)(ban)。不(bu)允(yun)許使用電鍍(du)(du)(du)鋅(xin)(xin)鋼(gang)(gang)板(ban)(ban)，電鍍(du)(du)(du)鋅(xin)(xin)鋼(gang)(gang)板(ban)(ban)僅在基材表面(mian)形成(cheng)保護層，防(fang)腐(fu)(fu)能(neng)力(li)有(you)限(xian)。目前市(shi)場上有(you)鍍(du)(du)(du)鋅(xin)(xin)鋼(gang)(gang)板(ban)(ban)（鍍(du)(du)(du)層含鋁(lv)5%或55%），在酸性環(huan)境下的(de)防(fang)腐(fu)(fu)效(xiao)果(guo)由于(yu)熱浸鍍(du)(du)(du)鋅(xin)(xin)鋼(gang)(gang)板(ban)(ban)，但在混凝土(tu)的(de)堿(jian)性條件下，鍍(du)(du)(du)鋁(lv)鋅(xin)(xin)的(de)防(fang)腐(fu)(fu)蝕性能(neng)低于(yu)熱浸鍍(du)(du)(du)鋅(xin)(xin)鋼(gang)(gang)板(ban)(ban)，且鋁(lv)會(hui)和(he)混凝土(tu)發生反應(ying)，并降(jiang)低混凝土(tu)與(yu)鋼(gang)(gang)板(ban)(ban)的(de)粘結性能(neng)。因此參考國外規范(fan)，及國內(nei)外工程，行家壓(ya)(ya)型(xing)鋼(gang)(gang)板(ban)(ban)不(bu)建議使用鍍(du)(du)(du)鋁(lv)鋅(xin)(xin)鋼(gang)(gang)板(ban)(ban)。

鍍鋅卷批發鍍鋅鋼板為基板的彩涂鋼板，除有鋅保護外，鋅層上的有機涂層起了覆蓋隔離作用，可防止鋼板生銹，使用壽命比鍍鋅鋼板更長，據介紹涂層鋼板的使用壽命比鍍鋅鋼板長50%。巫溪鍍鋅卷在(zai)(zai)連續機組上(shang)(shang)以冷(leng)軋帶鋼(gang)，鍍(du)鋅(xin)(xin)帶鋼(gang)（電鍍(du)鋅(xin)(xin)和熱鍍(du)鋅(xin)(xin)）為基板(ban)，經過表面(mian)預處理(li)（脫脂和化(hua)學(xue)處理(li)），用輥涂(tu)(tu)的方法，涂(tu)(tu)上(shang)(shang)一層(ceng)(ceng)或多層(ceng)(ceng)液態(tai)涂(tu)(tu)料(liao)，經過烘烤和冷(leng)卻所(suo)得的板(ban)材(cai)即為涂(tu)(tu)層(ceng)(ceng)鋼(gang)板(ban)。由于涂(tu)(tu)層(ceng)(ceng)可(ke)以有各種(zhong)不同的顏色，習慣上(shang)(shang)把涂(tu)(tu)層(ceng)(ceng)鋼(gang)板(ban)叫做彩(cai)色涂(tu)(tu)層(ceng)(ceng)鋼(gang)板(ban)。又由于涂(tu)(tu)層(ceng)(ceng)是在(zai)(zai)鋼(gang)板(ban)成型加工之(zhi)前進(jin)行的，在(zai)(zai)國(guo)外(wai)這叫做預涂(tu)(tu)層(ceng)(ceng)鋼(gang)板(ban)。
