南川熱鍍鋅重慶樓承板分兩種。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。熱鍍鋅價格樓(lou)(lou)承(cheng)板(ban)(ban)作(zuo)為受(shou)力(li)鋼(gang)筋計(ji)(ji)算，就(jiu)按(an)照模板(ban)(ban)的(de)(de)選用樓(lou)(lou)承(cheng)板(ban)(ban)（或(huo)者加厚且只能加厚），然后在(zai)計(ji)(ji)算配筋的(de)(de)時候(hou)可以按(an)照面積減少鋼(gang)筋用量。樓(lou)(lou)承(cheng)板(ban)(ban)不(bu)能單獨計(ji)(ji)算的(de)(de)，它和整個(ge)樓(lou)(lou)板(ban)(ban)是一個(ge)體系(xi)的(de)(de)。

重慶鍍鋅(xin)板(ban)(ban)(ban)(ban)(ban)按生(sheng)產及加(jia)工(gong)(gong)方法可分為(wei)以下幾(ji)類： 熱浸(jin)(jin)鍍鋅(xin)鋼板(ban)(ban)(ban)(ban)(ban)。將薄鋼板(ban)(ban)(ban)(ban)(ban)浸(jin)(jin)入(ru)熔(rong)解的(de)(de)鋅(xin)槽中(zhong)，使(shi)其(qi)表面粘附一層鋅(xin)的(de)(de)薄鋼板(ban)(ban)(ban)(ban)(ban)。目前(qian)主要采用(yong)連續鍍鋅(xin)工(gong)(gong)藝生(sheng)產，即把成(cheng)(cheng)(cheng)卷的(de)(de)鋼板(ban)(ban)(ban)(ban)(ban)連續浸(jin)(jin)在熔(rong)解有鋅(xin)的(de)(de)鍍槽中(zhong)制成(cheng)(cheng)(cheng)鍍鋅(xin)鋼板(ban)(ban)(ban)(ban)(ban)； 合(he)金(jin)化鍍鋅(xin)鋼板(ban)(ban)(ban)(ban)(ban)。為(wei)克服單面未(wei)涂(tu)鋅(xin)的(de)(de)缺點(dian)，又有一種在另面涂(tu)以薄層鋅(xin)的(de)(de)鍍鋅(xin)板(ban)(ban)(ban)(ban)(ban)，即雙面差鍍鋅(xin)板(ban)(ban)(ban)(ban)(ban)；合(he)金(jin)、復合(he)鍍鋅(xin)鋼板(ban)(ban)(ban)(ban)(ban)。它是用(yong)鋅(xin)和其(qi)他(ta)金(jin)屬如鉛、鋅(xin)制成(cheng)(cheng)(cheng)合(he)金(jin)乃至復合(he)鍍成(cheng)(cheng)(cheng)的(de)(de)鋼板(ban)(ban)(ban)(ban)(ban)。這種鋼板(ban)(ban)(ban)(ban)(ban)既具有防銹性(xing)(xing)能，又有良好(hao)的(de)(de)涂(tu)裝(zhuang)性(xing)(xing)能。

鍍(du)(du)(du)(du)鋅(xin)板選擇(ze)(ze)要(yao)(yao)(yao)(yao)(yao)注重的(de)(de)(de)幾個要(yao)(yao)(yao)(yao)(yao)點，工(gong)業(ye)(ye)(ye)企業(ye)(ye)(ye)的(de)(de)(de)客戶選擇(ze)(ze)專用工(gong)業(ye)(ye)(ye)原料，要(yao)(yao)(yao)(yao)(yao)注重從(cong)四個標準。一是(shi)(shi)(shi)要(yao)(yao)(yao)(yao)(yao)注重品(pin)(pin)(pin)牌來(lai)(lai)進行選擇(ze)(ze)，因(yin)為鍍(du)(du)(du)(du)鋅(xin)技術的(de)(de)(de)要(yao)(yao)(yao)(yao)(yao)求嚴格，所(suo)以(yi)有的(de)(de)(de)基礎(chu)，當然產(chan)(chan)品(pin)(pin)(pin)質(zhi)量與(yu)(yu)(yu)技術標準都(dou)會更可(ke)靠(kao)，都(dou)會有好(hao)的(de)(de)(de)專業(ye)(ye)(ye)標準。二是(shi)(shi)(shi)要(yao)(yao)(yao)(yao)(yao)注重產(chan)(chan)品(pin)(pin)(pin)本身的(de)(de)(de)鍍(du)(du)(du)(du)層質(zhi)量，鍍(du)(du)(du)(du)層一要(yao)(yao)(yao)(yao)(yao)靠(kao)技術，二要(yao)(yao)(yao)(yao)(yao)靠(kao)純度(du)，所(suo)以(yi)從(cong)產(chan)(chan)品(pin)(pin)(pin)表面(mian)來(lai)(lai)看質(zhi)量，這是(shi)(shi)(shi)基本也是(shi)(shi)(shi)重要(yao)(yao)(yao)(yao)(yao)的(de)(de)(de)一個標準。三是(shi)(shi)(shi)要(yao)(yao)(yao)(yao)(yao)看基礎(chu)材(cai)料。鍍(du)(du)(du)(du)鋅(xin)板基礎(chu)金屬材(cai)料的(de)(de)(de)質(zhi)量，與(yu)(yu)(yu)成品(pin)(pin)(pin)鍍(du)(du)(du)(du)鋅(xin)板的(de)(de)(de)質(zhi)量與(yu)(yu)(yu)耐用性密(mi)切相關，所(suo)以(yi)在進行產(chan)(chan)品(pin)(pin)(pin)選擇(ze)(ze)的(de)(de)(de)時候，需要(yao)(yao)(yao)(yao)(yao)注重這個細(xi)節，而材(cai)料的(de)(de)(de)提(ti)供，就是(shi)(shi)(shi)對于工(gong)業(ye)(ye)(ye)生產(chan)(chan)來(lai)(lai)說，有基礎(chu)條件。四是(shi)(shi)(shi)要(yao)(yao)(yao)(yao)(yao)注重價格對比(bi)，不(bu)是(shi)(shi)(shi)好(hao)的(de)(de)(de)就是(shi)(shi)(shi)貴的(de)(de)(de)，但(dan)是(shi)(shi)(shi)如果廉價的(de)(de)(de)把產(chan)(chan)品(pin)(pin)(pin)，那是(shi)(shi)(shi)不(bu)可(ke)信的(de)(de)(de)。
