重(zhong)慶鍍鋅板(ban)(ban)(ban)按生產及加工方法(fa)可分為以下幾類： 熱浸鍍鋅鋼(gang)(gang)板(ban)(ban)(ban)。將薄鋼(gang)(gang)板(ban)(ban)(ban)浸入熔(rong)解(jie)的(de)鋅槽中，使其(qi)表面(mian)粘附一(yi)層(ceng)鋅的(de)薄鋼(gang)(gang)板(ban)(ban)(ban)。目前主要采用連(lian)續鍍鋅工藝(yi)生產，即把成(cheng)(cheng)卷的(de)鋼(gang)(gang)板(ban)(ban)(ban)連(lian)續浸在熔(rong)解(jie)有鋅的(de)鍍槽中制成(cheng)(cheng)鍍鋅鋼(gang)(gang)板(ban)(ban)(ban)； 合(he)(he)金(jin)化(hua)鍍鋅鋼(gang)(gang)板(ban)(ban)(ban)。為克(ke)服單(dan)面(mian)未(wei)涂(tu)鋅的(de)缺點，又(you)有一(yi)種在另面(mian)涂(tu)以薄層(ceng)鋅的(de)鍍鋅板(ban)(ban)(ban)，即雙面(mian)差鍍鋅板(ban)(ban)(ban)；合(he)(he)金(jin)、復合(he)(he)鍍鋅鋼(gang)(gang)板(ban)(ban)(ban)。它是(shi)用鋅和其(qi)他金(jin)屬如(ru)鉛(qian)、鋅制成(cheng)(cheng)合(he)(he)金(jin)乃至復合(he)(he)鍍成(cheng)(cheng)的(de)鋼(gang)(gang)板(ban)(ban)(ban)。這種鋼(gang)(gang)板(ban)(ban)(ban)既具有防銹性(xing)能，又(you)有良好的(de)涂(tu)裝性(xing)能。

遼寧白鐵樓承板鋼結構柱網間距一般5~9.0m×8~15m，次梁間距3m，而樓承板下料長度為4.97~8.97m，運輸與安裝均較困難，尤其是帶由圓弧區垂直吊裝樓承板，由上而下在次梁狹間穿套比較困難，且打亂了次梁焊接正常工序。控制下料長度為3～6m，則可避免垂直運輸時在次梁間無法吊運的問題。 白鐵價格樓(lou)承板(ban)(ban)吊(diao)(diao)運(yun)時(shi)(shi)(shi)(shi)采用(yong)(yong)專用(yong)(yong)軟(ruan)吊(diao)(diao)索。每(mei)次吊(diao)(diao)裝時(shi)(shi)(shi)(shi)應(ying)檢查軟(ruan)吊(diao)(diao)索是否有撕裂、割(ge)斷(duan)現象。樓(lou)承板(ban)(ban)擱置在(zai)鋼梁(liang)上(shang)時(shi)(shi)(shi)(shi)應(ying)防(fang)止探頭。鋪(pu)料時(shi)(shi)(shi)(shi)操作人員應(ying)系(xi)帶，并(bing)保證邊鋪(pu)設邊固定在(zai)周(zhou)邊繩上(shang)。 焊(han)接(jie)采用(yong)(yong)熔(rong)透點(dian)焊(han)連(lian)接(jie)，施焊(han)前(qian)應(ying)準備邊角料引弧(hu)試焊(han)，調整施焊(han)電流.因樓(lou)承板(ban)(ban)底部(bu)無水平模板(ban)(ban)及(ji)垂直支撐，澆筑混凝土時(shi)(shi)(shi)(shi)布料不宜太集中，采用(yong)(yong)平板(ban)(ban)振搗(dao)器及(ji)時(shi)(shi)(shi)(shi)分攤振搗(dao)。
