隨著鋼(gang)結(jie)構在(zai)(zai)建筑材料中的(de)(de)(de)興(xing)起，越來越多的(de)(de)(de)人選擇使用(yong)(yong)鋼(gang)結(jie)構樓承(cheng)板(ban)(ban)(ban)(ban)了(le)，鋼(gang)結(jie)構構件(jian)工(gong)(gong)(gong)廠產業(ye)化生產大大縮短了(le)工(gong)(gong)(gong)程工(gong)(gong)(gong)期，而樓板(ban)(ban)(ban)(ban)的(de)(de)(de)施工(gong)(gong)(gong)方法卻成為(wei)影響(xiang)工(gong)(gong)(gong)期的(de)(de)(de)重要(yao)因素。采(cai)用(yong)(yong)那一(yi)代(dai)樓承(cheng)板(ban)(ban)(ban)(ban)對于樓板(ban)(ban)(ban)(ban)的(de)(de)(de)耐(nai)火性能也有區別。樓承(cheng)板(ban)(ban)(ban)(ban)的(de)(de)(de)厚(hou)度(du)(du)一(yi)般都是(shi)(shi)按保險起見設計的(de)(de)(de)比較厚(hou)，正常情況(kuang)下鋼(gang)梁之間的(de)(de)(de)跨度(du)(du)在(zai)(zai)2m以內(nei)樓承(cheng)板(ban)(ban)(ban)(ban)厚(hou)度(du)(du)在(zai)(zai)0.75-0.8mm就(jiu)可(ke)以了(le)，2-2.5m樓承(cheng)板(ban)(ban)(ban)(ban)厚(hou)度(du)(du)用(yong)(yong)0.8-1.0就(jiu)可(ke)以了(le)，跨度(du)(du)在(zai)(zai)3-4米樓承(cheng)板(ban)(ban)(ban)(ban)厚(hou)度(du)(du)用(yong)(yong)1.5mm，超過5m的(de)(de)(de)跨度(du)(du)是(shi)(shi)用(yong)(yong)臨(lin)時支撐，因素就(jiu)是(shi)(shi)混(hun)泥(ni)土澆(jiao)筑的(de)(de)(de)高度(du)(du)，混(hun)泥(ni)土澆(jiao)筑的(de)(de)(de)越高，樓承(cheng)板(ban)(ban)(ban)(ban)所(suo)需要(yao)的(de)(de)(de)厚(hou)度(du)(du)也就(jiu)越厚(hou)，還有一(yi)個(ge)大家容(rong)易(yi)忽(hu)略的(de)(de)(de)因素就(jiu)是(shi)(shi)螺釘的(de)(de)(de)好壞也是(shi)(shi)決定(ding)樓承(cheng)板(ban)(ban)(ban)(ban)厚(hou)度(du)(du)的(de)(de)(de)，螺釘越好樓承(cheng)板(ban)(ban)(ban)(ban)的(de)(de)(de)承(cheng)載(zai)力就(jiu)越強(qiang)。

近期(qi)(qi)鋼價延續低(di)迷(mi)，隨著通(tong)國規(gui)模(mo)的酷暑和旱季到(dao)來，熱(re)鍍(du)鋅卷(juan)板價格商場逐漸進入需要旺季，海(hai)內鋼鐵商場或將窄幅(fu)調整。在決策層(ceng)兩(liang)手抓制度(du)措施落實狀況(kuang)、貨銀本位度(du)定向寬松力度(du)加(jia)大的直觀層(ceng)面利好牽動下，商場信(xin)念逐漸趨穩(wen)，短期(qi)(qi)海(hai)內鋼價無望止跌(die)(die)企(qi)穩(wen);另一上面，以后鋼價殺跌(die)(die)電能有(you)余，而上漲也仍然屏障重重。熱(re)鍍(du)鋅卷(juan)板價格價錢或將長期(qi)(qi)在于低(di)位運行場面。

商洛鍍鋅板重慶樓承板的鍍鋅量沒有一個具體的標準，制作壓型鋼板的冷軋鋼卷須連續熱浸鍍鋅（或鍍鋁鋅），鍍（鋁）鋅量視設計要求而定。鍍鋅板廠家樓承板(ban)(ban)用(yong)壓型(xing)鋼(gang)(gang)板(ban)(ban)宜選(xuan)擇熱(re)浸(jin)鍍鋅(xin)(xin)鋼(gang)(gang)板(ban)(ban)。不允許(xu)使用(yong)電(dian)鍍鋅(xin)(xin)鋼(gang)(gang)板(ban)(ban)，電(dian)鍍鋅(xin)(xin)鋼(gang)(gang)板(ban)(ban)僅在基材表面形(xing)成保護層，防腐(fu)能(neng)力有(you)限。目前(qian)市場上有(you)鍍鋅(xin)(xin)鋼(gang)(gang)板(ban)(ban)（鍍層含鋁5%或(huo)55%），在酸性(xing)環(huan)境下的(de)防腐(fu)效果由(you)于熱(re)浸(jin)鍍鋅(xin)(xin)鋼(gang)(gang)板(ban)(ban)，但在混凝土(tu)的(de)堿性(xing)條(tiao)件下，鍍鋁鋅(xin)(xin)的(de)防腐(fu)蝕性(xing)能(neng)低(di)于熱(re)浸(jin)鍍鋅(xin)(xin)鋼(gang)(gang)板(ban)(ban)，且(qie)鋁會和(he)混凝土(tu)發生反應，并(bing)降(jiang)低(di)混凝土(tu)與鋼(gang)(gang)板(ban)(ban)的(de)粘結性(xing)能(neng)。因此(ci)參考國外規范，及國內(nei)外工程，行家壓型(xing)鋼(gang)(gang)板(ban)(ban)不建議使用(yong)鍍鋁鋅(xin)(xin)鋼(gang)(gang)板(ban)(ban)。
