判斷銅(tong)門(men)好壞的主要因素

價格(ge)(ge)：這(zhe)是(shi)要(yao)將材(cai)料、工藝和利潤放(fang)在(zai)一起后計(ji)算出來的(de)價格(ge)(ge)，就一套好的(de)實木復合門(men)基本上都(dou)是(shi)在(zai)2000元左右。但是(shi)所(suo)有的(de)材(cai)料使(shi)用都(dou)是(shi)產(chan)品，一些鎖具和五金都(dou)是(shi)進口(kou)的(de)話，這(zhe)樣(yang)的(de)門(men)有的(de)能夠達(da)到上萬(wan)元。

漆(qi)面(mian)(mian)：檢驗(yan)銅門(men)漆(qi)面(mian)(mian)是否光滑(hua)之外(wai)，還(huan)需(xu)要仔細去(qu)看(kan)其表面(mian)(mian)有沒有磕碰、疵(ci)點等硬(ying)傷之類的外(wai)，還(huan)有兩種(zhong)常(chang)見方(fang)式，一(yi)(yi)種(zhong)就是使用手背撫摸漆(qi)面(mian)(mian)，因為(wei)手背的皮比較(jiao)敏(min)感(gan)一(yi)(yi)點，如(ru)果感(gan)覺到漆(qi)面(mian)(mian)有微(wei)小的灰(hui)塵顆粒，別墅公寓雙開門(men)廠商，則說明(ming)烤漆(qi)工藝或是環境不(bu)達標;另一(yi)(yi)種(zhong)就是將門(men)扇卸下來，對這(zhe)燈(deng)光去(qu)看(kan)，這(zhe)能夠看(kan)到產品是否平(ping)整。

五(wu)金：折頁靜音(yin)(yin)鎖具(ju)彈性好鎖具(ju)等五(wu)金件的(de)好壞也是(shi)檢驗木門優劣的(de)重要因素。首先，好的(de)鎖具(ju)是(shi)銅(tong)質的(de)，應(ying)該(gai)很沉;然后轉(zhuan)動門把(ba)手，聽(ting)到的(de)門簧回(hui)彈的(de)聲音(yin)(yin)應(ying)該(gai)是(shi)清脆的(de);

這(zhe)幾(ji)點都判斷一扇銅門何不合格的(de)方式，在看的(de)時候一定要仔細(xi)了，不然(ran)在使用(yong)之(zhi)后(hou)就會出(chu)現這(zhe)樣那樣的(de)問題，并且還(huan)會影(ying)響你的(de)生活。

      隨著(zhu)銅門在(zai)我們(men)生活(huo)當(dang)(dang)中的(de)(de)不(bu)斷使用，這種門類的(de)(de)生產量也是(shi)(shi)越來越多了，同時生產廠(chang)家也就(jiu)慢慢的(de)(de)增加了不(bu)少，但(dan)是(shi)(shi)無(wu)論(lun)是(shi)(shi)什么(me)我們(men)在(zai)使用的(de)(de)過程(cheng)當(dang)(dang)中，還(huan)是(shi)(shi)對于銅門的(de)(de)生產廠(chang)家來說，它的(de)(de)價(jia)格問(wen)題(ti)都是(shi)(shi)非常重要的(de)(de)，別墅公寓雙開門多少錢(qian)，因為如果(guo)價(jia)格過高(gao)或者(zhe)(zhe)是(shi)(shi)過低都不(bu)會特別公平，過高(gao)的(de)(de)價(jia)格雖(sui)然可以(yi)給廠(chang)家帶來很高(gao)的(de)(de)利(li)潤，但(dan)是(shi)(shi)對于消(xiao)費者(zhe)(zhe)來說，就(jiu)會有點(dian)上當(dang)(dang)的(de)(de)感覺(jue);而如果(guo)太低的(de)(de)話，消(xiao)費者(zhe)(zhe)雖(sui)然拍手(shou)叫(jiao)好，但(dan)是(shi)(shi)對于廠(chang)家卻(que)是(shi)(shi)沒有利(li)潤可圖的(de)(de)，所以(yi)當(dang)(dang)我們(men)想(xiang)要了解(jie)銅門價(jia)格的(de)(de)話，可以(yi)從以(yi)下兩個方面(mian)進行考(kao)慮。

也(ye)可(ke)以(yi)按面積(ji)進行推算

銅門除了在(zai)一些g檔小(xiao)區的(de)(de)大廳里使(shi)用到(dao)上面(mian)(mian)所(suo)說的(de)(de)旋轉門外，基本上我(wo)們自己家里使(shi)用的(de)(de)話，都(dou)是單元門或者是銅r戶門，像這樣的(de)(de)銅門就需(xu)要按所(suo)需(xu)要的(de)(de)面(mian)(mian)積進(jin)行推算而得出價(jia)格，因為(wei)它(ta)有自己的(de)(de)款式和(he)花(hua)式，在(zai)基本的(de)(de)材料(liao)價(jia)格上面(mian)(mian)再(zai)把這些制作工(gong)(gong)藝和(he)加工(gong)(gong)手法進(jin)行推算和(he)加價(jia)。

不(bu)過，我們說的(de)只是(shi)純銅(tong)(tong)門(men)(men)的(de)價格，像現(xian)在市場上出現(xian)的(de)一些(xie)仿銅(tong)(tong)門(men)(men)，就不(bu)會有(you)這么高的(de)價格了(le)，因為它們使用的(de)材(cai)質(zhi)不(bu)同，原材(cai)料本(ben)來價格就非常便宜，再加上質(zhi)量不(bu)過關，所以仿銅(tong)(tong)門(men)(men)的(de)價格和(he)質(zhi)量和(he)純銅(tong)(tong)門(men)(men)都(dou)是(shi)無法相提并論(lun)的(de)。
