城口電鍍鋅重慶鍍鋅板按生產及加工方法可分為以下幾類： 熱浸鍍鋅鋼板。將薄鋼板浸入熔解的鋅槽中，使其表面粘附一層鋅的薄鋼板。目前主要采用連續鍍鋅工藝生產，即把成卷的鋼板連續浸在熔解有鋅的鍍槽中制成鍍鋅鋼板； 合金化鍍鋅鋼板。電鍍鋅價格為克服單面未涂(tu)鋅(xin)的缺點，又有一種在另面涂(tu)以(yi)薄層鋅(xin)的鍍鋅(xin)板(ban)(ban)，即雙面差鍍鋅(xin)板(ban)(ban)；合(he)金、復(fu)合(he)鍍鋅(xin)鋼板(ban)(ban)。它是用(yong)鋅(xin)和(he)其(qi)他金屬如鉛、鋅(xin)制成(cheng)合(he)金乃至復(fu)合(he)鍍成(cheng)的鋼板(ban)(ban)。這種鋼板(ban)(ban)既具(ju)有防銹性(xing)能，又有良好的涂(tu)裝性(xing)能。

樓(lou)承(cheng)(cheng)板(ban)(ban)鋼(gang)結構柱網間(jian)(jian)(jian)距(ju)一般5~9.0m×8~15m，次梁(liang)(liang)間(jian)(jian)(jian)距(ju)3m，而樓(lou)承(cheng)(cheng)板(ban)(ban)下(xia)料長度為4.97~8.97m，運(yun)輸(shu)與安(an)裝(zhuang)均較困(kun)難，尤其是帶由(you)圓弧區垂(chui)直(zhi)(zhi)吊(diao)裝(zhuang)樓(lou)承(cheng)(cheng)板(ban)(ban)，由(you)上而下(xia)在(zai)(zai)次梁(liang)(liang)狹間(jian)(jian)(jian)穿套比(bi)較困(kun)難，且打(da)亂了次梁(liang)(liang)焊(han)接(jie)(jie)正常工序(xu)。控制(zhi)下(xia)料長度為3～6m，則可避(bi)免(mian)垂(chui)直(zhi)(zhi)運(yun)輸(shu)時(shi)(shi)在(zai)(zai)次梁(liang)(liang)間(jian)(jian)(jian)無(wu)法吊(diao)運(yun)的問題(ti)。 樓(lou)承(cheng)(cheng)板(ban)(ban)吊(diao)運(yun)時(shi)(shi)采(cai)用專用軟(ruan)(ruan)吊(diao)索。每次吊(diao)裝(zhuang)時(shi)(shi)應檢查軟(ruan)(ruan)吊(diao)索是否有(you)撕裂、割斷現(xian)象。樓(lou)承(cheng)(cheng)板(ban)(ban)擱置在(zai)(zai)鋼(gang)梁(liang)(liang)上時(shi)(shi)應防止(zhi)探頭。鋪料時(shi)(shi)操作人員應系(xi)帶，并保證邊鋪設(she)邊固(gu)定在(zai)(zai)周邊繩上。 焊(han)接(jie)(jie)采(cai)用熔透點焊(han)連接(jie)(jie)，施焊(han)前(qian)應準備(bei)邊角料引弧試焊(han)，調整(zheng)施焊(han)電流.因樓(lou)承(cheng)(cheng)板(ban)(ban)底部無(wu)水(shui)平模板(ban)(ban)及(ji)垂(chui)直(zhi)(zhi)支撐，澆(jiao)筑混凝土時(shi)(shi)布料不(bu)宜太(tai)集中，采(cai)用平板(ban)(ban)振(zhen)搗(dao)器及(ji)時(shi)(shi)分攤振(zhen)搗(dao)。
