乙級(ji)防火(huo)門(men)(men)的(de)價(jia)錢會受門(men)(men)類型、材(cai)質以(yi)及生產(chan)地的(de)影(ying)響。一般來(lai)說，品(pin)質普通的(de)木制(zhi)或(huo)鋼制(zhi)的(de)乙級(ji)普通木質隔熱(re)防火(huo)門(men)(men)外(wai)報價(jia)大概在**120元/m2到385元/m3之間；而(er)玻璃(li)的(de)則(ze)在幾百元左右一個(ge)平米（含五(wu)金(jin)件開啟方向(xiang)等）。價(jia)格會有浮(fu)動變化：有品(pin)牌及正(zheng)規(gui)品(pin)牌的(de)優缺點如(ru)下:優點是和售后保障;劣(lie)質產(chan)品(pin)則(ze)容(rong)易出現閉鎖卡榫不順暢(chang)等現象，甚至沒(mei)有密封性。如(ru)果你需要具體某一型號的(de)價(jia)格建議咨詢廠家(jia)或(huo)者商家(jia)進行確認哦！
