熱鍍鋅卷板價格行業統計數據(ju)顯示，十一月(yue)國(guo)內(nei)粗鋼(gang)日均產量為兩(liang)百零九(jiu)萬噸，環比下降3.3%，創出今年以(yi)來水平，但(dan)是當前(qian)減(jian)產受到季節性因素(su)支撐，市(shi)場(chang)(chang)對數據(ju)有效性提出質(zhi)疑。鍍鋅卷工(gong)業品(pin)而(er)言，近期陸續公(gong)布的重要(yao)數據(ju)中性偏(pian)多。但(dan)值(zhi)得注意的是，同年十一月(yue)熱鍍鋅卷板價格工(gong)業增加(jia)(jia)值(zhi)和投資增速(su)放緩，進一步印證(zheng)了(le)國(guo)內(nei)總需(xu)求乏力，工(gong)業復蘇(su)形勢不(bu)容(rong)樂觀(guan)。加(jia)(jia)上未(wei)來經(jing)濟結(jie)構調(diao)整等因素(su)，工(gong)業品(pin)價格反彈高度將有限。傳統需(xu)求淡季效應還在持續不(bu)斷地發酵，冬(dong)儲(chu)效果不(bu)佳。雖然數據(ju)顯示供應壓力開(kai)始減(jian)輕，但(dan)是目前(qian)處于鋼(gang)鐵需(xu)求淡季，市(shi)場(chang)(chang)成交萎縮，下游采購遲遲未(wei)能有效跟進，市(shi)場(chang)(chang)信心(xin)不(bu)足，鍍鋅鋼(gang)板貿易(yi)商囤貨現象也不(bu)明(ming)顯。

樓(lou)(lou)承板(ban)鋼結構(gou)柱網間(jian)距一般5~9.0m×8~15m，次(ci)(ci)梁(liang)間(jian)距3m，而(er)樓(lou)(lou)承板(ban)下料(liao)長度為4.97~8.97m，運(yun)輸與(yu)安裝(zhuang)均(jun)較(jiao)困難(nan)，尤其是(shi)帶由圓弧區垂直吊(diao)(diao)裝(zhuang)樓(lou)(lou)承板(ban)，由上而(er)下在次(ci)(ci)梁(liang)狹間(jian)穿套(tao)比(bi)較(jiao)困難(nan)，且打亂(luan)了次(ci)(ci)梁(liang)焊接(jie)正常工序。控制下料(liao)長度為3～6m，則可(ke)避免(mian)垂直運(yun)輸時在次(ci)(ci)梁(liang)間(jian)無法吊(diao)(diao)運(yun)的(de)問題(ti)。 樓(lou)(lou)承板(ban)吊(diao)(diao)運(yun)時采用(yong)專用(yong)軟吊(diao)(diao)索。每次(ci)(ci)吊(diao)(diao)裝(zhuang)時應(ying)檢查軟吊(diao)(diao)索是(shi)否有撕裂、割斷現象。樓(lou)(lou)承板(ban)擱置(zhi)在鋼梁(liang)上時應(ying)防止探(tan)頭。鋪料(liao)時操作人員應(ying)系帶，并保(bao)證邊鋪設邊固定在周邊繩上。 焊接(jie)采用(yong)熔透點焊連接(jie)，施焊前應(ying)準備邊角料(liao)引弧試(shi)焊，調(diao)整施焊電流.因樓(lou)(lou)承板(ban)底(di)部無水(shui)平模板(ban)及垂直支(zhi)撐，澆(jiao)筑混凝土時布(bu)料(liao)不宜太集中，采用(yong)平板(ban)振搗器及時分攤振搗。

樓(lou)(lou)(lou)(lou)承板鍍(du)(du)(du)(du)鋅(xin)(xin)首(shou)要起到防(fang)腐的(de)效果，按標準組(zu)合(he)樓(lou)(lou)(lou)(lou)板與非組(zu)合(he)樓(lou)(lou)(lou)(lou)板壓(ya)型鋼板應選用(yong)熱鍍(du)(du)(du)(du)鋅(xin)(xin)，不(bu)(bu)(bu)該選用(yong)電鍍(du)(du)(du)(du)鋅(xin)(xin)鋼板，其雙面鍍(du)(du)(du)(du)鋅(xin)(xin)層(ceng)總(zong)含(han)量(liang)要滿足(zu)在使(shi)用(yong)期間不(bu)(bu)(bu)致銹(xiu)損的(de)要求。當作為(wei)(wei)(wei)非組(zu)合(he)樓(lou)(lou)(lou)(lou)承板時(shi)，鍍(du)(du)(du)(du)鋅(xin)(xin)層(ceng)含(han)量(liang)可選用(yong)較低值(zhi);當為(wei)(wei)(wei)組(zu)合(he)樓(lou)(lou)(lou)(lou)承板時(shi)，鍍(du)(du)(du)(du)鋅(xin)(xin)層(ceng)含(han)量(liang)不(bu)(bu)(bu)該小(xiao)于150g/m2。當為(wei)(wei)(wei)組(zu)合(he)樓(lou)(lou)(lou)(lou)板且使(shi)用(yong)環(huan)境條件較為(wei)(wei)(wei)惡劣時(shi)，鍍(du)(du)(du)(du)鋅(xin)(xin)層(ceng)含(han)量(liang)應選用(yong)上(shang)限值(zhi)或更高(gao)值(zhi)。更高(gao)的(de)鍍(du)(du)(du)(du)鋅(xin)(xin)要求，如雙面鍍(du)(du)(du)(du)鋅(xin)(xin)量(liang)為(wei)(wei)(wei)300g/m2、350g/m2或鍍(du)(du)(du)(du)鋁鋅(xin)(xin)(5%鋁)275g/m2、300g/m2等，較高(gao)的(de)鍍(du)(du)(du)(du)層(ceng)量(liang)使(shi)組(zu)合(he)樓(lou)(lou)(lou)(lou)板有更長(chang)耐久(jiu)性(xing)，同等量(liang)的(de)鍍(du)(du)(du)(du)鋁鋅(xin)(xin)的(de)防(fang)銹(xiu)蝕才(cai)能大約兩倍于一般熱鍍(du)(du)(du)(du)鋅(xin)(xin)。鍍(du)(du)(du)(du)鋅(xin)(xin)量(liang)也不(bu)(bu)(bu)是(shi)越厚越好(hao)，當鍍(du)(du)(du)(du)鋅(xin)(xin)量(liang)較厚時(shi)，抗剪(jian)連接件栓釘的(de)焊(han)接質(zhi)量(liang)就很難保證，焊(han)接時(shi)，宜選用(yong)局部除鋅(xin)(xin)處(chu)理(li)措施。
