用電(dian)鍍(du)(du)(du)(du)(du)法(fa)制造這種鍍(du)(du)(du)(du)(du)鋅(xin)(xin)(xin)(xin)(xin)鋼(gang)(gang)板(ban)(ban)(ban)(ban)(ban)(ban)具(ju)有(you)(you)良(liang)好的加(jia)工(gong)(gong)性。但鍍(du)(du)(du)(du)(du)層(ceng)較薄，耐腐蝕性不如(ru)熱浸(jin)法(fa)鍍(du)(du)(du)(du)(du)鋅(xin)(xin)(xin)(xin)(xin)板(ban)(ban)(ban)(ban)(ban)(ban)；單面(mian)(mian)(mian)鍍(du)(du)(du)(du)(du)和雙面(mian)(mian)(mian)差鍍(du)(du)(du)(du)(du)鋅(xin)(xin)(xin)(xin)(xin)鋼(gang)(gang)板(ban)(ban)(ban)(ban)(ban)(ban)。單面(mian)(mian)(mian)鍍(du)(du)(du)(du)(du)鋅(xin)(xin)(xin)(xin)(xin)鋼(gang)(gang)板(ban)(ban)(ban)(ban)(ban)(ban)，即只在一面(mian)(mian)(mian)鍍(du)(du)(du)(du)(du)鋅(xin)(xin)(xin)(xin)(xin)的產品。在焊(han)接、涂(tu)裝(zhuang)、防銹(xiu)處理、加(jia)工(gong)(gong)等方面(mian)(mian)(mian)，具(ju)有(you)(you)比(bi)雙面(mian)(mian)(mian)鍍(du)(du)(du)(du)(du)鋅(xin)(xin)(xin)(xin)(xin)板(ban)(ban)(ban)(ban)(ban)(ban)好的適應性。為克服單面(mian)(mian)(mian)未涂(tu)鋅(xin)(xin)(xin)(xin)(xin)的缺點，又有(you)(you)一種在另面(mian)(mian)(mian)涂(tu)以薄層(ceng)鋅(xin)(xin)(xin)(xin)(xin)的鍍(du)(du)(du)(du)(du)鋅(xin)(xin)(xin)(xin)(xin)板(ban)(ban)(ban)(ban)(ban)(ban)，即雙面(mian)(mian)(mian)差鍍(du)(du)(du)(du)(du)鋅(xin)(xin)(xin)(xin)(xin)板(ban)(ban)(ban)(ban)(ban)(ban)；合(he)金(jin)、復合(he)鍍(du)(du)(du)(du)(du)鋅(xin)(xin)(xin)(xin)(xin)鋼(gang)(gang)板(ban)(ban)(ban)(ban)(ban)(ban)。它是(shi)用鋅(xin)(xin)(xin)(xin)(xin)和其他金(jin)屬如(ru)鉛、鋅(xin)(xin)(xin)(xin)(xin)制成(cheng)合(he)金(jin)乃(nai)至(zhi)復合(he)鍍(du)(du)(du)(du)(du)成(cheng)的鋼(gang)(gang)板(ban)(ban)(ban)(ban)(ban)(ban)。這種鋼(gang)(gang)板(ban)(ban)(ban)(ban)(ban)(ban)既具(ju)有(you)(you)防銹(xiu)性能，又有(you)(you)良(liang)好的涂(tu)裝(zhuang)性能。 除上述五(wu)種外，還(huan)有(you)(you)彩色鍍(du)(du)(du)(du)(du)鋅(xin)(xin)(xin)(xin)(xin)鋼(gang)(gang)板(ban)(ban)(ban)(ban)(ban)(ban)、印花涂(tu)裝(zhuang)鍍(du)(du)(du)(du)(du)鋅(xin)(xin)(xin)(xin)(xin)鋼(gang)(gang)板(ban)(ban)(ban)(ban)(ban)(ban)、聚氯乙烯疊層(ceng)鍍(du)(du)(du)(du)(du)鋅(xin)(xin)(xin)(xin)(xin)鋼(gang)(gang)板(ban)(ban)(ban)(ban)(ban)(ban)等。但目(mu)前常用的仍(reng)為熱浸(jin)鍍(du)(du)(du)(du)(du)鋅(xin)(xin)(xin)(xin)(xin)板(ban)(ban)(ban)(ban)(ban)(ban)。 鍍(du)(du)(du)(du)(du)鋅(xin)(xin)(xin)(xin)(xin)鋼(gang)(gang)板(ban)(ban)(ban)(ban)(ban)(ban)按用途又可分為一般用、屋頂用、建筑外側板(ban)(ban)(ban)(ban)(ban)(ban)用、結構用、瓦(wa)壟板(ban)(ban)(ban)(ban)(ban)(ban)用、拉(la)伸用和深沖用等鍍(du)(du)(du)(du)(du)鋅(xin)(xin)(xin)(xin)(xin)鋼(gang)(gang)板(ban)(ban)(ban)(ban)(ban)(ban)。

近期(qi)(qi)鋼(gang)(gang)價延續低迷，隨著通國規(gui)模的酷(ku)暑(shu)和(he)旱季到來(lai)，熱鍍鋅卷板價格商場(chang)逐(zhu)漸進入需要旺季，海(hai)內鋼(gang)(gang)鐵商場(chang)或(huo)(huo)將窄(zhai)幅調整。在(zai)決(jue)策層兩(liang)手抓制度(du)措施落實狀況、貨銀本(ben)位度(du)定向(xiang)寬松力度(du)加大的直觀(guan)層面利好牽動(dong)下，商場(chang)信念(nian)逐(zhu)漸趨(qu)穩，短期(qi)(qi)海(hai)內鋼(gang)(gang)價無望止跌企(qi)穩;另(ling)一上面，以(yi)后鋼(gang)(gang)價殺跌電(dian)能(neng)有余，而(er)上漲也仍然屏障重(zhong)重(zhong)。熱鍍鋅卷板價格價錢或(huo)(huo)將長期(qi)(qi)在(zai)于(yu)低位運(yun)行場(chang)面。

重慶(qing)樓(lou)承(cheng)板(ban)(ban)分(fen)兩種(zhong)(zhong)。一(yi)(yi)種(zhong)(zhong)是把樓(lou)承(cheng)板(ban)(ban)當做承(cheng)受(shou)(shou)拉(la)力(li)的鋼筋計(ji)算(suan)(suan)的，另外一(yi)(yi)種(zhong)(zhong)是僅把樓(lou)承(cheng)板(ban)(ban)作為(wei)模板(ban)(ban)計(ji)算(suan)(suan)而不參與受(shou)(shou)力(li)的。做模板(ban)(ban)計(ji)算(suan)(suan)的比較簡單(dan)，直(zhi)接按(an)(an)照跨度頂就行了。2米(mi)(mi)以(yi)下選(xuan)0.8的，2-3米(mi)(mi)的選(xuan)1.0的。樓(lou)承(cheng)板(ban)(ban)作為(wei)受(shou)(shou)力(li)鋼筋計(ji)算(suan)(suan)，就按(an)(an)照模板(ban)(ban)的選(xuan)用樓(lou)承(cheng)板(ban)(ban)（或者加厚且(qie)只能加厚），然(ran)后在(zai)計(ji)算(suan)(suan)配(pei)筋的時(shi)候(hou)可以(yi)按(an)(an)照面積減少鋼筋用量。樓(lou)承(cheng)板(ban)(ban)不能單(dan)獨計(ji)算(suan)(suan)的，它和整個樓(lou)板(ban)(ban)是一(yi)(yi)個體系的。

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(du)(du)(du)鋅(xin)量是(shi)表示鍍(du)(du)(du)鋅(xin)板鋅(xin)層厚(hou)度的(de)一個普遍采用(yong)的(de)有效方法。鍍(du)(du)(du)鋅(xin)量的(de)單位為g/m2。鍍(du)(du)(du)鋅(xin)層通過鈍化(hua)處理(li)，可減少潮(chao)溫貯(zhu)運條件下產生折(zhe)銹蝕(白銹) 。但這種化(hua)學處理(li)的(de)防腐蝕性能是(shi)有限(xian)的(de)，而且，妨礙大多數涂料的(de)附(fu)著性。這種處理(li)一般不用(yong)在鋅(xin)鐵合金(jin)鍍(du)(du)(du)層，除光整表面(mian)外，作為常規，生產廠(chang)對其他類型的(de)鍍(du)(du)(du)鋅(xin)層均進(jin)行鈍化(hua)處理(li)。
