近期鋼(gang)(gang)(gang)價(jia)(jia)延續低迷(mi)，隨(sui)著通國規模的酷(ku)暑和(he)旱季到來，熱鍍鋅(xin)卷板(ban)(ban)價(jia)(jia)格商場(chang)(chang)逐(zhu)漸進入(ru)需要旺季，海內(nei)鋼(gang)(gang)(gang)鐵(tie)商場(chang)(chang)或(huo)將(jiang)窄幅調整。在(zai)決策層(ceng)兩手抓制度(du)(du)措(cuo)施落實狀況、貨銀本位(wei)度(du)(du)定(ding)向寬(kuan)松力(li)度(du)(du)加(jia)大的直觀層(ceng)面(mian)利好牽(qian)動下，商場(chang)(chang)信念逐(zhu)漸趨穩，短期海內(nei)鋼(gang)(gang)(gang)價(jia)(jia)無望止跌企(qi)穩;另一上面(mian)，以后鋼(gang)(gang)(gang)價(jia)(jia)殺跌電能有余(yu)，而上漲也仍(reng)然屏障重(zhong)重(zhong)。熱鍍鋅(xin)卷板(ban)(ban)價(jia)(jia)格價(jia)(jia)錢(qian)或(huo)將(jiang)長期在(zai)于低位(wei)運行場(chang)(chang)面(mian)。

樓(lou)(lou)承(cheng)板(ban)(ban)(ban)(ban)組合板(ban)(ban)(ban)(ban)是一種十分合理(li)的結(jie)構(gou)方式，它(ta)能(neng)(neng)(neng)夠按其各組成部件所處的方位(wei)和(he)特色，充分發揮鋼材抗拉和(he)混凝(ning)(ning)土抗壓功能(neng)(neng)(neng)好的長處，并具有杰(jie)出的抗震功能(neng)(neng)(neng)、施(shi)工功能(neng)(neng)(neng)。這(zhe)種結(jie)構(gou)現在(zai)被廣泛(fan)運(yun)用于(yu)國(guo)內外修建(jian)中(zhong)(zhong)，但在(zai)國(guo)內大都將樓(lou)(lou)承(cheng)板(ban)(ban)(ban)(ban)當作(zuo)模板(ban)(ban)(ban)(ban)運(yun)用，而沒有充分發揮樓(lou)(lou)承(cheng)板(ban)(ban)(ban)(ban)的效果。 與一般鋼筋(jin)混凝(ning)(ning)土樓(lou)(lou)板(ban)(ban)(ban)(ban)比(bi)較，樓(lou)(lou)承(cheng)板(ban)(ban)(ban)(ban)組合樓(lou)(lou)板(ban)(ban)(ban)(ban)具備以(yi)下長處：樓(lou)(lou)承(cheng)板(ban)(ban)(ban)(ban)能(neng)(neng)(neng)夠作(zuo)為現澆混凝(ning)(ning)土的模板(ban)(ban)(ban)(ban)。這(zhe)樣就(jiu)省掉了施(shi)工中(zhong)(zhong)裝置和(he)撤除模板(ban)(ban)(ban)(ban)等工序，然(ran)后節約(yue)了時刻和(he)勞動力(li);當樓(lou)(lou)承(cheng)板(ban)(ban)(ban)(ban)裝置好今后將能(neng)(neng)(neng)夠作(zuo)為施(shi)工平臺(tai)運(yun)用。

重慶鍍(du)鋅(xin)板(ban)按生產及加工方(fang)法可分為以下幾類： 熱浸(jin)鍍(du)鋅(xin)鋼(gang)(gang)板(ban)。將薄鋼(gang)(gang)板(ban)浸(jin)入熔解的(de)鋅(xin)槽(cao)中，使其表面粘(zhan)附一(yi)層鋅(xin)的(de)薄鋼(gang)(gang)板(ban)。目前主要(yao)采用連續鍍(du)鋅(xin)工藝生產，即把成卷的(de)鋼(gang)(gang)板(ban)連續浸(jin)在熔解有(you)(you)鋅(xin)的(de)鍍(du)槽(cao)中制(zhi)成鍍(du)鋅(xin)鋼(gang)(gang)板(ban)； 合(he)(he)(he)金化鍍(du)鋅(xin)鋼(gang)(gang)板(ban)。為克服單面未涂(tu)(tu)鋅(xin)的(de)缺點(dian)，又有(you)(you)一(yi)種在另(ling)面涂(tu)(tu)以薄層鋅(xin)的(de)鍍(du)鋅(xin)板(ban)，即雙面差鍍(du)鋅(xin)板(ban)；合(he)(he)(he)金、復(fu)合(he)(he)(he)鍍(du)鋅(xin)鋼(gang)(gang)板(ban)。它是用鋅(xin)和(he)其他金屬如鉛、鋅(xin)制(zhi)成合(he)(he)(he)金乃至(zhi)復(fu)合(he)(he)(he)鍍(du)成的(de)鋼(gang)(gang)板(ban)。這種鋼(gang)(gang)板(ban)既具有(you)(you)防銹性能，又有(you)(you)良(liang)好的(de)涂(tu)(tu)裝性能。

鍍鋅管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。江津鍍鋅管熱(re)鍍鋅帶鋼在我國(guo)(guo)市場一(yi)直是緊缺品種。從20世紀(ji)90年代中期以來(lai)，每年都要從國(guo)(guo)外進口80-100萬t左右。隨著國(guo)(guo)內經濟的(de)發展，尤其是汽車(che)、家電及建筑業的(de)發展，對(dui)鍍鋅帶鋼的(de)需(xu)求量也大大增加。
