我國(guo)建(jian)(jian)(jian)筑業中，噪聲污染(ran)問題久為人(ren)(ren)們所(suo)詬病。輕型樓(lou)承(cheng)(cheng)板(ban)的(de)(de)應(ying)用使得土(tu)建(jian)(jian)(jian)建(jian)(jian)(jian)筑物局(ju)面(mian)被打破(po)，集環境破(po)壞及污染(ran)少、材料回收和(he)利(li)用率高(gao)、符(fu)合(he)可持續發(fa)展要求等(deng)眾多(duo)優點于(yu)一身(shen)的(de)(de)樓(lou)承(cheng)(cheng)板(ban)建(jian)(jian)(jian)筑應(ying)運而(er)生，逐(zhu)步被人(ren)(ren)們所(suo)接受。輕型樓(lou)承(cheng)(cheng)板(ban)是近(jin)十年來發(fa)展較快的(de)(de)領域，在(zai)采用輕型樓(lou)承(cheng)(cheng)板(ban)占非住宅建(jian)(jian)(jian)筑投資的(de)(de)50%以上。這(zhe)種(zhong)結(jie)構(gou)(gou)工業化(hua)、商(shang)品(pin)化(hua)程(cheng)度(du)高(gao)，施工快，綜合(he)效益高(gao)，市場需求量很(hen)大(da)，已(yi)(yi)引起結(jie)構(gou)(gou)設計(ji)人(ren)(ren)員認識。樓(lou)承(cheng)(cheng)板(ban)的(de)(de)研究(jiu)開發(fa)已(yi)(yi)在(zai)各地試點，是輕鋼發(fa)展的(de)(de)一個重要方(fang)向，目前(qian)已(yi)(yi)經有多(duo)種(zhong)的(de)(de)低層(ceng)(ceng)、多(duo)層(ceng)(ceng)和(he)高(gao)層(ceng)(ceng)的(de)(de)設計(ji)方(fang)案和(he)實例。

鍍(du)鋅(xin)(xin)鋼(gang)(gang)(gang)板(ban)(ban)(ban)(ban)為(wei)基板(ban)(ban)(ban)(ban)的彩(cai)涂(tu)(tu)鋼(gang)(gang)(gang)板(ban)(ban)(ban)(ban)，除有鋅(xin)(xin)保護外(wai)，鋅(xin)(xin)層(ceng)上的有機涂(tu)(tu)層(ceng)起(qi)了覆(fu)蓋(gai)隔離作用(yong)(yong)，可防止鋼(gang)(gang)(gang)板(ban)(ban)(ban)(ban)生銹，使用(yong)(yong)壽命比(bi)鍍(du)鋅(xin)(xin)鋼(gang)(gang)(gang)板(ban)(ban)(ban)(ban)更長，據介(jie)紹涂(tu)(tu)層(ceng)鋼(gang)(gang)(gang)板(ban)(ban)(ban)(ban)的使用(yong)(yong)壽命比(bi)鍍(du)鋅(xin)(xin)鋼(gang)(gang)(gang)板(ban)(ban)(ban)(ban)長50%。在連續機組上以冷(leng)(leng)軋帶(dai)鋼(gang)(gang)(gang)，鍍(du)鋅(xin)(xin)帶(dai)鋼(gang)(gang)(gang)（電鍍(du)鋅(xin)(xin)和熱鍍(du)鋅(xin)(xin)）為(wei)基板(ban)(ban)(ban)(ban)，經(jing)(jing)過表面(mian)預處理（脫脂(zhi)和化學處理），用(yong)(yong)輥涂(tu)(tu)的方法，涂(tu)(tu)上一層(ceng)或多層(ceng)液(ye)態涂(tu)(tu)料，經(jing)(jing)過烘(hong)烤和冷(leng)(leng)卻所(suo)得(de)的板(ban)(ban)(ban)(ban)材(cai)即為(wei)涂(tu)(tu)層(ceng)鋼(gang)(gang)(gang)板(ban)(ban)(ban)(ban)。由(you)于涂(tu)(tu)層(ceng)可以有各種不同的顏色(se)，習慣上把涂(tu)(tu)層(ceng)鋼(gang)(gang)(gang)板(ban)(ban)(ban)(ban)叫(jiao)(jiao)做(zuo)彩(cai)色(se)涂(tu)(tu)層(ceng)鋼(gang)(gang)(gang)板(ban)(ban)(ban)(ban)。又由(you)于涂(tu)(tu)層(ceng)是在鋼(gang)(gang)(gang)板(ban)(ban)(ban)(ban)成型加工之前進(jin)行的，在國(guo)外(wai)這叫(jiao)(jiao)做(zuo)預涂(tu)(tu)層(ceng)鋼(gang)(gang)(gang)板(ban)(ban)(ban)(ban)。

樓(lou)(lou)(lou)承(cheng)(cheng)(cheng)板(ban)(ban)(ban)(ban)(ban)(ban)習慣主體鋼結(jie)構快速施工的(de)(de)要求，能夠(gou)在(zai)(zai)短時間(jian)內提供堅定的(de)(de)作(zuo)(zuo)(zuo)業渠道，并可采用多個樓(lou)(lou)(lou)層鋪設壓(ya)(ya)型鋼板(ban)(ban)(ban)(ban)(ban)(ban)，分層澆筑混(hun)(hun)凝土(tu)(tu)板(ban)(ban)(ban)(ban)(ban)(ban)的(de)(de)流水施工。在(zai)(zai)運用階段樓(lou)(lou)(lou)承(cheng)(cheng)(cheng)板(ban)(ban)(ban)(ban)(ban)(ban)作(zuo)(zuo)(zuo)為(wei)混(hun)(hun)凝土(tu)(tu)樓(lou)(lou)(lou)板(ban)(ban)(ban)(ban)(ban)(ban)的(de)(de)受拉鋼筋(jin)(jin)，也提高了樓(lou)(lou)(lou)板(ban)(ban)(ban)(ban)(ban)(ban)的(de)(de)剛(gang)度(du)，節省了鋼筋(jin)(jin)和混(hun)(hun)凝土(tu)(tu)的(de)(de)用量(liang)。樓(lou)(lou)(lou)承(cheng)(cheng)(cheng)板(ban)(ban)(ban)(ban)(ban)(ban)上面能夠(gou)鋪設保溫，隔音(yin)，隔熱，隔振等資料(liao)。改進(jin)樓(lou)(lou)(lou)面性能充分發揮鋼的(de)(de)杰出的(de)(de)抗(kang)(kang)拉強度(du)和延性及混(hun)(hun)凝土(tu)(tu)優(you)良的(de)(de)抗(kang)(kang)壓(ya)(ya)強度(du)和較(jiao)大的(de)(de)剛(gang)度(du)。壓(ya)(ya)型板(ban)(ban)(ban)(ban)(ban)(ban)表面壓(ya)(ya)紋使(shi)樓(lou)(lou)(lou)承(cheng)(cheng)(cheng)板(ban)(ban)(ban)(ban)(ban)(ban)與混(hun)(hun)凝土(tu)(tu)之間(jian)產生大的(de)(de)結(jie)合力(li)，使(shi)二者(zhe)形成整體，配以加勁肋，使(shi)樓(lou)(lou)(lou)承(cheng)(cheng)(cheng)板(ban)(ban)(ban)(ban)(ban)(ban)體系具有高強承(cheng)(cheng)(cheng)載力(li)。在(zai)(zai)懸(xuan)臂(bei)條件下，樓(lou)(lou)(lou)承(cheng)(cheng)(cheng)板(ban)(ban)(ban)(ban)(ban)(ban)僅(jin)作(zuo)(zuo)(zuo)為(wei)性模板(ban)(ban)(ban)(ban)(ban)(ban)。懸(xuan)挑(tiao)的(de)(de)長度(du)可根據樓(lou)(lou)(lou)承(cheng)(cheng)(cheng)板(ban)(ban)(ban)(ban)(ban)(ban)的(de)(de)截(jie)面特(te)性來定。為(wei)了避免懸(xuan)挑(tiao)板(ban)(ban)(ban)(ban)(ban)(ban)的(de)(de)開裂，需在(zai)(zai)支座處依結(jie)構工程(cheng)師的(de)(de)規劃(hua)配上負筋(jin)(jin)。本公司樓(lou)(lou)(lou)承(cheng)(cheng)(cheng)板(ban)(ban)(ban)(ban)(ban)(ban)已通過(guo)國家固定救活體系及耐(nai)火(huo)(huo)構件質量(liang)檢測(ce)中(zhong)心的(de)(de)耐(nai)火(huo)(huo)檢測(ce)，作(zuo)(zuo)(zuo)為(wei)組合樓(lou)(lou)(lou)承(cheng)(cheng)(cheng)板(ban)(ban)(ban)(ban)(ban)(ban)無需防火(huo)(huo)噴(pen)涂(tu)，因而(er)大大降(jiang)低了工程(cheng)造(zao)價。

由于我國(guo)鋅(xin)資源比(bi)較豐富，鍍(du)鋅(xin)又是(shi)一種(zhong)價廉、能防銹，又能裝飾(shi)的高性(xing)價比(bi)鍍(du)種(zhong)，因(yin)而在汽(qi)車(che)、機(ji)械、電子、船(chuan)舶、儀(yi)表、輕工(gong)等工(gong)業部(bu)門得到廣(guang)泛的應用(yong)。如機(ji)械零(ling)件(jian)(jian)、低壓(ya)電器、高壓(ya)開(kai)關、緊固連接件(jian)(jian)、鋼鐵結構件(jian)(jian)、建(jian)筑五金、農(nong)業機(ji)械、輕工(gong)產品(pin)等都離不開(kai)鍍(du)鋅(xin)鈍化(hua)制品(pin)。鍍(du)鋅(xin)板卷(juan)因(yin)此可分(fen)為熱(re)軋鍍(du)鋅(xin)板卷(juan)和冷軋熱(re)鍍(du)鋅(xin)板卷(juan)，它(ta)們主(zhu)要用(yong)于建(jian)筑、家電、汽(qi)車(che)、容器、交通及家業等領域。特別(bie)是(shi)鋼結構建(jian)筑、汽(qi)車(che)制造(zao)、鋼板倉制造(zao)等行業。 重慶鍍(du)鋅(xin)卷(juan)特點主(zhu)要為：耐腐蝕強(qiang)、表面(mian)質(zhi)量好(hao)、得利于深加工(gong)、經濟(ji)實(shi)用(yong)等。

鍍鋅板價格熱鍍鋅生產發展一直處于滯后狀態。20世紀50年代到60年代陸續建成了13條單張鋼板熔劑法熱鍍鋅機組，能力為10萬t/a，但因產量低、成本高、質量差、污染環境、經濟效益差等缺陷已先后停、轉產。從20世紀70年代末，我國才開始建造大型寬帶熱鍍鋅機組。商洛鍍鋅板熱鍍(du)鋅(xin)帶(dai)鋼在我國市場一直是緊(jin)缺品(pin)種。從20世紀90年代中期以來，每年都要從國外(wai)進口(kou)80-100萬t左右。隨著(zhu)國內經(jing)濟的(de)發展(zhan)，尤其是汽車、家電及(ji)建(jian)筑業的(de)發展(zhan)，對鍍(du)鋅(xin)帶(dai)鋼的(de)需(xu)求量也大大增加。
