邛崍攀鋼冷軋卷隨著鋼結構在建筑材料中的興起，越來越多的人選擇使用鋼結構樓承板了，鋼結構構件工廠產業化生產大大縮短了工程工期，而樓板的施工方法卻成為影響工期的重要因素。采用那一代樓承板對于樓板的耐火性能也有區別。冷軋卷價格樓(lou)(lou)(lou)承(cheng)板(ban)(ban)(ban)的(de)(de)厚度(du)(du)(du)一般都(dou)是按保險起見設計的(de)(de)比較厚，正常(chang)情(qing)況下鋼梁之間(jian)的(de)(de)跨(kua)度(du)(du)(du)在2m以內樓(lou)(lou)(lou)承(cheng)板(ban)(ban)(ban)厚度(du)(du)(du)在0.75-0.8mm就(jiu)(jiu)(jiu)可(ke)以了，2-2.5m樓(lou)(lou)(lou)承(cheng)板(ban)(ban)(ban)厚度(du)(du)(du)用(yong)0.8-1.0就(jiu)(jiu)(jiu)可(ke)以了，跨(kua)度(du)(du)(du)在3-4米樓(lou)(lou)(lou)承(cheng)板(ban)(ban)(ban)厚度(du)(du)(du)用(yong)1.5mm，超過5m的(de)(de)跨(kua)度(du)(du)(du)是用(yong)臨(lin)時(shi)支撐(cheng)，因素(su)就(jiu)(jiu)(jiu)是混(hun)泥土澆(jiao)筑的(de)(de)高(gao)(gao)度(du)(du)(du)，混(hun)泥土澆(jiao)筑的(de)(de)越(yue)(yue)(yue)高(gao)(gao)，樓(lou)(lou)(lou)承(cheng)板(ban)(ban)(ban)所需(xu)要的(de)(de)厚度(du)(du)(du)也就(jiu)(jiu)(jiu)越(yue)(yue)(yue)厚，還(huan)有一個大家容易忽略(lve)的(de)(de)因素(su)就(jiu)(jiu)(jiu)是螺(luo)釘(ding)的(de)(de)好壞也是決定樓(lou)(lou)(lou)承(cheng)板(ban)(ban)(ban)厚度(du)(du)(du)的(de)(de)，螺(luo)釘(ding)越(yue)(yue)(yue)好樓(lou)(lou)(lou)承(cheng)板(ban)(ban)(ban)的(de)(de)承(cheng)載力就(jiu)(jiu)(jiu)越(yue)(yue)(yue)強。

鍍(du)鋅(xin)(xin)鋼(gang)板按用(yong)(yong)(yong)途(tu)又可(ke)分(fen)為(wei)一(yi)(yi)般(ban)(ban)用(yong)(yong)(yong)、屋頂用(yong)(yong)(yong)、建筑(zhu)外(wai)側(ce)板用(yong)(yong)(yong)、結(jie)構用(yong)(yong)(yong)、瓦壟板用(yong)(yong)(yong)、拉伸用(yong)(yong)(yong)和(he)(he)深沖用(yong)(yong)(yong)等鍍(du)鋅(xin)(xin)鋼(gang)板。對于一(yi)(yi)般(ban)(ban)防(fang)(fang)(fang)保護用(yong)(yong)(yong)鍍(du)層(ceng)，可(ke)以(yi)采(cai)(cai)用(yong)(yong)(yong)堿性(xing)鋅(xin)(xin)酸鹽(yan)鍍(du)鋅(xin)(xin)彩色(se)鈍(dun)(dun)化(hua)工藝。有時為(wei)了(le)產品的(de)(de)(de)(de)配(pei)色(se)需要，也可(ke)以(yi)采(cai)(cai)用(yong)(yong)(yong)藍白色(se)鈍(dun)(dun)化(hua)工藝，比如(ru)軍綠(lv)色(se)鈍(dun)(dun)化(hua)、黑(hei)色(se)鈍(dun)(dun)化(hua)等。為(wei)提(ti)高鋼(gang)管(guan)的(de)(de)(de)(de)耐腐蝕(shi)性(xing)能，對一(yi)(yi)般(ban)(ban)鋼(gang)管(guan)進行(xing)鍍(du)鋅(xin)(xin)。鍍(du)鋅(xin)(xin)卷(juan)分(fen)熱鍍(du)鋅(xin)(xin)和(he)(he)電(dian)(dian)鍍(du)鋅(xin)(xin)兩(liang)種，熱鍍(du)鋅(xin)(xin)鍍(du)鋅(xin)(xin)層(ceng)厚，電(dian)(dian)鍍(du)鋅(xin)(xin)成(cheng)本低，表面不(bu)是(shi)很光滑。吹氧焊管(guan)：用(yong)(yong)(yong)作(zuo)煉鋼(gang)吹氧用(yong)(yong)(yong)管(guan)，一(yi)(yi)般(ban)(ban)用(yong)(yong)(yong)小口徑(jing)的(de)(de)(de)(de)焊接鋼(gang)管(guan)，規格由(you)3/8-2寸八(ba)種。用(yong)(yong)(yong)08、10、15、20或者195-Q235的(de)(de)(de)(de)鋼(gang)帶制作(zuo)成(cheng)的(de)(de)(de)(de)，為(wei)了(le)防(fang)(fang)(fang)腐蝕(shi)，有得進行(xing)滲(shen)鋁處理(li)。鍍(du)鋅(xin)(xin)其防(fang)(fang)(fang)護作(zuo)用(yong)(yong)(yong)更強，抗腐蝕(shi)能力強。整個結(jie)構由(you)鋅(xin)(xin)，形(xing)成(cheng)致密的(de)(de)(de)(de)四(si)元結(jie)晶(jing)體(ti)，此(ci)結(jie)晶(jing)體(ti)在鋼(gang)板上形(xing)成(cheng)一(yi)(yi)層(ceng)屏障(zhang)， 因而有效的(de)(de)(de)(de)防(fang)(fang)(fang)止腐蝕(shi)因子穿透。 耐腐蝕(shi)性(xing)來自鋅(xin)(xin)的(de)(de)(de)(de)障(zhang)礙層(ceng)保護功能強。

熱鍍(du)鋅(xin)(xin)生(sheng)產(chan)發展一(yi)直處于滯后狀(zhuang)態(tai)。20世紀50年(nian)(nian)代到60年(nian)(nian)代陸續(xu)建(jian)成(cheng)了(le)13條單張(zhang)鋼板熔劑法(fa)熱鍍(du)鋅(xin)(xin)機組，能力為(wei)10萬(wan)t/a，但因(yin)產(chan)量(liang)(liang)低、成(cheng)本高、質量(liang)(liang)差、污染環境(jing)、經(jing)濟效(xiao)益差等缺(que)陷(xian)已先后停(ting)、轉產(chan)。從20世紀70年(nian)(nian)代末，我國(guo)才開始建(jian)造(zao)大型寬帶(dai)熱鍍(du)鋅(xin)(xin)機組。熱鍍(du)鋅(xin)(xin)帶(dai)鋼在我國(guo)市場一(yi)直是緊(jin)缺(que)品種。從20世紀90年(nian)(nian)代中期以來(lai)，每年(nian)(nian)都要從國(guo)外進(jin)口80-100萬(wan)t左右。隨(sui)著國(guo)內經(jing)濟的發展，尤其是汽車(che)、家電及建(jian)筑(zhu)業的發展，對鍍(du)鋅(xin)(xin)帶(dai)鋼的需求量(liang)(liang)也大大增加(jia)。

由(you)于我國鋅(xin)(xin)(xin)(xin)資源(yuan)比較豐富，鍍(du)(du)鋅(xin)(xin)(xin)(xin)又是一(yi)種(zhong)價(jia)廉、能防(fang)銹，又能裝飾的高(gao)性價(jia)比鍍(du)(du)種(zhong)，因而在(zai)汽(qi)車(che)、機(ji)械、電(dian)(dian)子、船舶(bo)、儀表、輕工(gong)(gong)(gong)等(deng)(deng)工(gong)(gong)(gong)業(ye)部門(men)得(de)到廣泛的應用(yong)。如(ru)機(ji)械零件(jian)、低(di)壓電(dian)(dian)器、高(gao)壓開關、緊固連接件(jian)、鋼鐵結構(gou)(gou)件(jian)、建(jian)(jian)筑五金、農(nong)業(ye)機(ji)械、輕工(gong)(gong)(gong)產品等(deng)(deng)都離不開鍍(du)(du)鋅(xin)(xin)(xin)(xin)鈍化制(zhi)品。鍍(du)(du)鋅(xin)(xin)(xin)(xin)板卷(juan)因此可(ke)分為熱(re)(re)軋(ya)鍍(du)(du)鋅(xin)(xin)(xin)(xin)板卷(juan)和冷軋(ya)熱(re)(re)鍍(du)(du)鋅(xin)(xin)(xin)(xin)板卷(juan)，它們主(zhu)要用(yong)于建(jian)(jian)筑、家(jia)電(dian)(dian)、汽(qi)車(che)、容器、交通及家(jia)業(ye)等(deng)(deng)領域。特(te)(te)別是鋼結構(gou)(gou)建(jian)(jian)筑、汽(qi)車(che)制(zhi)造、鋼板倉制(zhi)造等(deng)(deng)行(xing)業(ye)。 重慶鍍(du)(du)鋅(xin)(xin)(xin)(xin)卷(juan)特(te)(te)點主(zhu)要為：耐腐蝕強、表面質量好、得(de)利于深加工(gong)(gong)(gong)、經濟實用(yong)等(deng)(deng)。
