實現了機械化生產，有利于鋼筋排列間距均勻、混凝土保護層厚度一致，提高了樓板的施工質量。渝北攀鋼熱鍍鋅裝配式鋼筋桁架樓承板可顯著減少現場鋼筋綁扎工程量，加快施工進度，增加施工保證，實現文明施工。熱鍍鋅批發裝配(pei)式(shi)模板和(he)連接件拆(chai)裝方(fang)便，可(ke)多次重復利(li)用，節約鋼(gang)(gang)材(cai)，符合國家節能(neng)(neng)環保(bao)的(de)要(yao)(yao)求。鋼(gang)(gang)構(gou)自主研發的(de)產(chan)(chan)品(pin)配(pei)套自動(dong)化生(sheng)產(chan)(chan)設備，大大提高了(le)勞動(dong)生(sheng)產(chan)(chan)率，有效降低(di)了(le)產(chan)(chan)品(pin)成(cheng)本，并編制了(le)產(chan)(chan)品(pin)生(sheng)產(chan)(chan)企業標準(zhun)、設計手(shou)冊(ce)和(he)節點構(gou)造圖集以及(ji)施工手(shou)冊(ce)。并經過多項工程(cheng)應用，各項性能(neng)(neng)可(ke)以滿(man)足現澆(jiao)鋼(gang)(gang)筋混凝(ning)土樓板承(cheng)載(zai)力和(he)變形的(de)要(yao)(yao)求。

熱鍍鋅(xin)(xin)(xin)卷板(ban)(ban)現貨(huo)(huo)消(xiao)息：熱鍍鋅(xin)(xin)(xin)產(chan)(chan)品廣泛用(yong)于建筑、家(jia)電(dian)、車船、容器制(zhi)造業(ye)、機電(dian)業(ye)等(deng)，幾乎涉及到(dao)衣(yi)食(shi)住行各個領域。近(jin)年(nian)來，世界鍍鋅(xin)(xin)(xin)鋼(gang)板(ban)(ban)需(xu)求量不斷增加，產(chan)(chan)量增長也很快，在美、日等(deng)鋼(gang)材生(sheng)產(chan)(chan)大國，熱鍍鋅(xin)(xin)(xin)鋼(gang)板(ban)(ban)在鋼(gang)材中(zhong)所占比例已(yi)高達13%-15%。 熱鍍鋅(xin)(xin)(xin)卷板(ban)(ban)現貨(huo)(huo)消(xiao)息：近(jin)來，汽車行業(ye)越來越重(zhong)視材料的(de)使(shi)用(yong)壽命(ming)，用(yong)涂漆冷軋鋼(gang)板(ban)(ban)已(yi)不能(neng)滿足耐腐蝕方面的(de)要求。在這(zhe)種情(qing)況下(xia)，耐腐蝕性(xing)優(you)良(liang)且(qie)成本低廉的(de)熱鍍鋅(xin)(xin)(xin)板(ban)(ban)開始普(pu)遍受到(dao)了汽車廠家(jia)的(de)青睞(lai)。

熱(re)鍍(du)(du)鋅生產發展(zhan)一直(zhi)處于(yu)滯后狀態。20世紀(ji)50年(nian)代到(dao)60年(nian)代陸續建成了(le)13條單張鋼(gang)(gang)板熔劑法(fa)熱(re)鍍(du)(du)鋅機(ji)組，能力為10萬t/a，但因產量低、成本高、質量差(cha)、污染環境、經(jing)濟(ji)效益差(cha)等缺陷已先后停、轉產。從20世紀(ji)70年(nian)代末，我國(guo)才開始建造大(da)型寬帶熱(re)鍍(du)(du)鋅機(ji)組。熱(re)鍍(du)(du)鋅帶鋼(gang)(gang)在我國(guo)市(shi)場一直(zhi)是(shi)緊缺品種。從20世紀(ji)90年(nian)代中期以來，每年(nian)都要(yao)從國(guo)外進口80-100萬t左右。隨(sui)著國(guo)內經(jing)濟(ji)的(de)發展(zhan)，尤其是(shi)汽車、家電及(ji)建筑業的(de)發展(zhan)，對鍍(du)(du)鋅帶鋼(gang)(gang)的(de)需求量也大(da)大(da)增加。
