巴中鍍鋅鋼重慶樓承板分兩種。一種是把樓承板當做承受拉力的鋼筋計算的，另外一種是僅把樓承板作為模板計算而不參與受力的。做模板計算的比較簡單，直接按照跨度頂就行了。2米以下選0.8的，2-3米的選1.0的。鍍鋅鋼批發樓(lou)承(cheng)板(ban)(ban)作為受力鋼筋(jin)(jin)計(ji)算，就按照模(mo)板(ban)(ban)的選用樓(lou)承(cheng)板(ban)(ban)（或者加厚(hou)且只(zhi)能加厚(hou)），然后(hou)在計(ji)算配筋(jin)(jin)的時候可(ke)以按照面積減少鋼筋(jin)(jin)用量。樓(lou)承(cheng)板(ban)(ban)不能單獨(du)計(ji)算的，它和整個樓(lou)板(ban)(ban)是一個體系的。

重慶鍍鋅(xin)(xin)(xin)(xin)板(ban)(ban)(ban)(ban)(ban)按生產及加工方法可分為(wei)以下幾(ji)類： 熱浸(jin)鍍鋅(xin)(xin)(xin)(xin)鋼(gang)(gang)(gang)板(ban)(ban)(ban)(ban)(ban)。將薄(bo)鋼(gang)(gang)(gang)板(ban)(ban)(ban)(ban)(ban)浸(jin)入熔解(jie)的(de)(de)鋅(xin)(xin)(xin)(xin)槽中(zhong)，使(shi)其表面(mian)粘附一層鋅(xin)(xin)(xin)(xin)的(de)(de)薄(bo)鋼(gang)(gang)(gang)板(ban)(ban)(ban)(ban)(ban)。目前(qian)主(zhu)要采用(yong)連(lian)續(xu)(xu)鍍鋅(xin)(xin)(xin)(xin)工藝生產，即把(ba)成(cheng)卷(juan)的(de)(de)鋼(gang)(gang)(gang)板(ban)(ban)(ban)(ban)(ban)連(lian)續(xu)(xu)浸(jin)在熔解(jie)有(you)鋅(xin)(xin)(xin)(xin)的(de)(de)鍍槽中(zhong)制成(cheng)鍍鋅(xin)(xin)(xin)(xin)鋼(gang)(gang)(gang)板(ban)(ban)(ban)(ban)(ban)； 合(he)金化鍍鋅(xin)(xin)(xin)(xin)鋼(gang)(gang)(gang)板(ban)(ban)(ban)(ban)(ban)。為(wei)克服單面(mian)未涂(tu)鋅(xin)(xin)(xin)(xin)的(de)(de)缺點，又有(you)一種(zhong)在另(ling)面(mian)涂(tu)以薄(bo)層鋅(xin)(xin)(xin)(xin)的(de)(de)鍍鋅(xin)(xin)(xin)(xin)板(ban)(ban)(ban)(ban)(ban)，即雙面(mian)差鍍鋅(xin)(xin)(xin)(xin)板(ban)(ban)(ban)(ban)(ban)；合(he)金、復(fu)合(he)鍍鋅(xin)(xin)(xin)(xin)鋼(gang)(gang)(gang)板(ban)(ban)(ban)(ban)(ban)。它是(shi)用(yong)鋅(xin)(xin)(xin)(xin)和其他金屬如(ru)鉛(qian)、鋅(xin)(xin)(xin)(xin)制成(cheng)合(he)金乃至復(fu)合(he)鍍成(cheng)的(de)(de)鋼(gang)(gang)(gang)板(ban)(ban)(ban)(ban)(ban)。這(zhe)種(zhong)鋼(gang)(gang)(gang)板(ban)(ban)(ban)(ban)(ban)既(ji)具有(you)防銹性能，又有(you)良好的(de)(de)涂(tu)裝性能。
