用(yong)(yong)電鍍(du)(du)法制造(zao)這種(zhong)(zhong)(zhong)鍍(du)(du)鋅(xin)(xin)(xin)(xin)(xin)鋼(gang)板(ban)(ban)(ban)(ban)具有(you)良好的(de)加工性(xing)。但鍍(du)(du)層較薄，耐腐蝕性(xing)不(bu)如熱浸(jin)法鍍(du)(du)鋅(xin)(xin)(xin)(xin)(xin)板(ban)(ban)(ban)(ban)；單面(mian)鍍(du)(du)和(he)雙面(mian)差(cha)鍍(du)(du)鋅(xin)(xin)(xin)(xin)(xin)鋼(gang)板(ban)(ban)(ban)(ban)。單面(mian)鍍(du)(du)鋅(xin)(xin)(xin)(xin)(xin)鋼(gang)板(ban)(ban)(ban)(ban)，即只在一面(mian)鍍(du)(du)鋅(xin)(xin)(xin)(xin)(xin)的(de)產品。在焊接、涂(tu)(tu)裝、防(fang)銹(xiu)處理、加工等(deng)方面(mian)，具有(you)比雙面(mian)鍍(du)(du)鋅(xin)(xin)(xin)(xin)(xin)板(ban)(ban)(ban)(ban)好的(de)適應性(xing)。為克服(fu)單面(mian)未(wei)涂(tu)(tu)鋅(xin)(xin)(xin)(xin)(xin)的(de)缺點，又(you)(you)有(you)一種(zhong)(zhong)(zhong)在另面(mian)涂(tu)(tu)以(yi)薄層鋅(xin)(xin)(xin)(xin)(xin)的(de)鍍(du)(du)鋅(xin)(xin)(xin)(xin)(xin)板(ban)(ban)(ban)(ban)，即雙面(mian)差(cha)鍍(du)(du)鋅(xin)(xin)(xin)(xin)(xin)板(ban)(ban)(ban)(ban)；合金、復合鍍(du)(du)鋅(xin)(xin)(xin)(xin)(xin)鋼(gang)板(ban)(ban)(ban)(ban)。它是(shi)用(yong)(yong)鋅(xin)(xin)(xin)(xin)(xin)和(he)其他金屬如鉛、鋅(xin)(xin)(xin)(xin)(xin)制成合金乃至(zhi)復合鍍(du)(du)成的(de)鋼(gang)板(ban)(ban)(ban)(ban)。這種(zhong)(zhong)(zhong)鋼(gang)板(ban)(ban)(ban)(ban)既具有(you)防(fang)銹(xiu)性(xing)能，又(you)(you)有(you)良好的(de)涂(tu)(tu)裝性(xing)能。 除上述五種(zhong)(zhong)(zhong)外，還有(you)彩色鍍(du)(du)鋅(xin)(xin)(xin)(xin)(xin)鋼(gang)板(ban)(ban)(ban)(ban)、印花涂(tu)(tu)裝鍍(du)(du)鋅(xin)(xin)(xin)(xin)(xin)鋼(gang)板(ban)(ban)(ban)(ban)、聚氯乙烯(xi)疊層鍍(du)(du)鋅(xin)(xin)(xin)(xin)(xin)鋼(gang)板(ban)(ban)(ban)(ban)等(deng)。但目前常用(yong)(yong)的(de)仍(reng)為熱浸(jin)鍍(du)(du)鋅(xin)(xin)(xin)(xin)(xin)板(ban)(ban)(ban)(ban)。 鍍(du)(du)鋅(xin)(xin)(xin)(xin)(xin)鋼(gang)板(ban)(ban)(ban)(ban)按用(yong)(yong)途又(you)(you)可分為一般(ban)用(yong)(yong)、屋(wu)頂用(yong)(yong)、建筑外側板(ban)(ban)(ban)(ban)用(yong)(yong)、結(jie)構用(yong)(yong)、瓦壟(long)板(ban)(ban)(ban)(ban)用(yong)(yong)、拉伸用(yong)(yong)和(he)深沖用(yong)(yong)等(deng)鍍(du)(du)鋅(xin)(xin)(xin)(xin)(xin)鋼(gang)板(ban)(ban)(ban)(ban)。

近期(qi)鋼(gang)價(jia)延續低迷，隨著通國規模的酷暑和旱(han)季到來，熱鍍鋅(xin)卷(juan)板(ban)價(jia)格(ge)商場逐(zhu)漸進入需(xu)要旺季，海(hai)內(nei)(nei)鋼(gang)鐵(tie)商場或(huo)將窄幅調整。在(zai)決策(ce)層(ceng)兩手抓制度(du)措施落實狀(zhuang)況、貨銀本位(wei)度(du)定向寬松(song)力度(du)加大的直觀層(ceng)面利好牽(qian)動下，商場信念(nian)逐(zhu)漸趨穩(wen)，短期(qi)海(hai)內(nei)(nei)鋼(gang)價(jia)無望(wang)止(zhi)跌企穩(wen);另一(yi)上面，以后鋼(gang)價(jia)殺跌電能有余，而上漲也(ye)仍然屏障重重。熱鍍鋅(xin)卷(juan)板(ban)價(jia)格(ge)價(jia)錢或(huo)將長期(qi)在(zai)于低位(wei)運行(xing)場面。

樓(lou)承(cheng)(cheng)板在(zai)建筑當(dang)中已(yi)經被廣(guang)泛(fan)的(de)(de)(de)使用，對于(yu)此種設(she)備(bei)的(de)(de)(de)標準化(hua)和工廠(chang)化(hua)的(de)(de)(de)程度已(yi)經是越來越高了，那么(me)它(ta)(ta)們現(xian)在(zai)已(yi)經發展(zhan)成為(wei)了產業(ye)化(hua)的(de)(de)(de)趨勢，那么(me)在(zai)未來對于(yu)桁(heng)架樓(lou)承(cheng)(cheng)板來說(shuo)(shuo)，應該有好(hao)(hao)的(de)(de)(de)市場發展(zhan)前景，現(xian)在(zai)我們就要來說(shuo)(shuo)一說(shuo)(shuo)鋼筋桁(heng)架樓(lou)承(cheng)(cheng)板在(zai)使用過程當(dang)中如何進行(xing)防(fang)腐(fu)的(de)(de)(de)操(cao)作。如今對于(yu)我們國家(jia)(jia)的(de)(de)(de)建筑鋼結構來說(shuo)(shuo)，它(ta)(ta)們的(de)(de)(de)發展(zhan)趨勢是特別好(hao)(hao)的(de)(de)(de)，它(ta)(ta)們也大(da)大(da)的(de)(de)(de)推動了我們國家(jia)(jia)的(de)(de)(de)冶金行(xing)業(ye)的(de)(de)(de)發展(zhan)，現(xian)在(zai)對于(yu)建筑行(xing)業(ye)和冶金行(xing)業(ye)已(yi)經緊(jin)緊(jin)的(de)(de)(de)聯系在(zai)一起了。對于(yu)未來我們的(de)(de)(de)鋼筋桁(heng)架樓(lou)承(cheng)(cheng)板將會處(chu)于(yu)一個新的(de)(de)(de)發展(zhan)時期。

重慶樓(lou)(lou)承(cheng)(cheng)板(ban)(ban)(ban)分兩種。一(yi)(yi)種是(shi)把(ba)樓(lou)(lou)承(cheng)(cheng)板(ban)(ban)(ban)當做(zuo)承(cheng)(cheng)受拉力(li)的(de)(de)鋼(gang)筋(jin)計(ji)(ji)(ji)(ji)算(suan)的(de)(de)，另外一(yi)(yi)種是(shi)僅把(ba)樓(lou)(lou)承(cheng)(cheng)板(ban)(ban)(ban)作(zuo)為模板(ban)(ban)(ban)計(ji)(ji)(ji)(ji)算(suan)而不參與受力(li)的(de)(de)。做(zuo)模板(ban)(ban)(ban)計(ji)(ji)(ji)(ji)算(suan)的(de)(de)比較簡(jian)單，直接(jie)按照(zhao)跨(kua)度頂就行(xing)了(le)。2米以下選0.8的(de)(de)，2-3米的(de)(de)選1.0的(de)(de)。樓(lou)(lou)承(cheng)(cheng)板(ban)(ban)(ban)作(zuo)為受力(li)鋼(gang)筋(jin)計(ji)(ji)(ji)(ji)算(suan)，就按照(zhao)模板(ban)(ban)(ban)的(de)(de)選用樓(lou)(lou)承(cheng)(cheng)板(ban)(ban)(ban)（或者加(jia)厚且只能加(jia)厚），然后(hou)在(zai)計(ji)(ji)(ji)(ji)算(suan)配(pei)筋(jin)的(de)(de)時候可(ke)以按照(zhao)面積減少鋼(gang)筋(jin)用量。樓(lou)(lou)承(cheng)(cheng)板(ban)(ban)(ban)不能單獨計(ji)(ji)(ji)(ji)算(suan)的(de)(de)，它(ta)和整個樓(lou)(lou)板(ban)(ban)(ban)是(shi)一(yi)(yi)個體系的(de)(de)。

鍍鋅管批發鍍鋅方管是一種具以熱軋或冷軋鍍鋅帶鋼或鍍鋅卷板為坯料經冷彎曲加工成型后再經高頻焊接制成的方形截面形狀尺寸的空心方形的截面型鋼鋼管；鍍鋅卷或將事先做好的冷彎空心型鋼管再經熱浸鍍鋅加工而成的鍍鋅方矩管。上海鍍鋅管鍍鋅量是表示鍍鋅板鋅層(ceng)厚度的(de)(de)(de)(de)一(yi)(yi)個普遍采用的(de)(de)(de)(de)有效方法(fa)。鍍鋅量的(de)(de)(de)(de)單位(wei)為(wei)g/m2。鍍鋅層(ceng)通過鈍(dun)化(hua)(hua)處(chu)理(li)，可減少潮(chao)溫貯運(yun)條件(jian)下(xia)產生折(zhe)銹蝕(shi)(白銹) 。但這(zhe)種化(hua)(hua)學(xue)處(chu)理(li)的(de)(de)(de)(de)防腐蝕(shi)性能(neng)是有限的(de)(de)(de)(de)，而且，妨礙大多數涂(tu)料的(de)(de)(de)(de)附著(zhu)性。這(zhe)種處(chu)理(li)一(yi)(yi)般不用在鋅鐵合金鍍層(ceng)，除光(guang)整(zheng)表面外，作為(wei)常(chang)規，生產廠對其他類型的(de)(de)(de)(de)鍍鋅層(ceng)均(jun)進行鈍(dun)化(hua)(hua)處(chu)理(li)。
