Muaj ntau qhov sib txawv siv rau galvanized steel yeeb nkab hauv ntau qhov kev lag luam. Qee qhov chaw tshaj plaws uas koj yuav pom galvanized steel yeeb nkab yog nyob rau hauv vaj tse thiab kev lag luam cua ducts los yog raws li cov khoom siv los tsim cov thoob khib nyiab pov tseg ntev. Nws ntseeg tau tias ntau tus neeg xav paub yuav ua li cas xaiv cov khoom siv hlau tsim nyog rau koj qhov project tom ntej. Qhov tseeb, muaj qee qhov teeb meem kev lag luam nyob rau hauv kev txiav txim siab. Cov peev nyiaj tuaj yeem yog qhov tseem ceeb.
Thaum nws los txog rau lo lus "tus nqi", nws ib txwm suav hais tias yog ib qho teeb meem tseem ceeb hauv kev lag luam kev lag luam, uas ib txwm yog qhov tseem ceeb ntawm txhua qhov kev lag luam kev lag luam. Los ntawm thiab loj, feem ntau, muaj qhov hloov pauv ntawm tus nqi steel tab sis qhov xwm txheej tag nrho yog qhov ruaj khov hauv kev lag luam steel. Tus nqi hloov pauv ntawm steel raj yog tshwm sim los ntawm ntau yam. Kev hais lus, kub dipped galvanized steel yeeb nkab yog cov yeeb nkab steel uas tau coated nrog zinc. Cov txheej no tiv thaiv cov hlau los ntawm kev siv corrosion. Nws yog feem ntau siv rau kev tsim kho sab nraum zoov xws li laj kab thiab tes tuav, lossis rau qee qhov kav dej sab hauv. Nws kuj yog qee zaum hu ua galvanized hlau yeeb nkab. Nyob rau hauv qhov tseeb steel yeeb nkab ntau lawm, cov ntaub ntawv hlau tau muab tso rau hauv lub molten da dej ntawm zinc los tsim cov txheej txheem ntawm zinc. Ob lub hlau yog chemically khi rau ib leeg nyob rau hauv cov txheej txheem no, thiab yog li ntawd yuav tsis sib cais, ua rau ib tug ntau resistant thiab ntev version ntawm steel. Vim yog cov ntaub ntawv zoo raw khoom thiab cov cuab yeej ua haujlwm nyuaj, tsis muaj qhov tsis ntseeg tias kub dipped galvanized steel yeeb nkab muaj tus nqi siab dua li lwm cov kav dej hauv kev lag luam steel. Nyob rau hauv tas li ntawd, tus nqi ntawm cov yeeb nkab steel kuj tseem kim nyob rau hauv kev sib piv nrog rau lwm tus nyob rau hauv 2018.
Kub dipped galvanized yeeb nkab tau suav hais tias nrov heev ntawm ntau cov neeg siv niaj hnub no. Rau ib yam, cov txheej txheem galvanization tiv thaiv cov hlau los ntawm xeb puas tuaj yeem tshwm sim thaum lub sijhawm thauj mus los, kev teeb tsa thiab kev pabcuam. Cov txheej zinc txheej ntawm cov yeeb nkab tuaj yeem tsim muaj kev tiv thaiv kev tiv thaiv rau cov khoom siv hlau kom ntev lub neej kev pab cuam hauv kev siv. Rau lwm yam, txheej txheej no kuj tiv taus hnav thiab khawb, uas ua rau cov hlau zoo nkauj dua. Nyob rau hauv daim ntawv thov, raws li ib tug sib txawv daim ntawv thov nyob ib ncig ntawm thiab txawv installation yuav tsum tau, nws yog pom tseeb hais tias cov duab thiab qhov luaj li cas ntawm cov yeeb nkab kuj ua rau ib tug tej yam kev cuam tshuam rau cov yeeb nkab nqi. Tshwj xeeb tshaj yog nyob rau hauv kev tsim kho niaj hnub no, galvanized steel yeeb nkab, uas yog ib qho tseem ceeb ntawm cov khoom siv hauv tsev, tau ua lub luag haujlwm tseem ceeb hauv kev tsim vaj tsev thiab qee qhov kev tsim kho vaj tsev hauv lub neej. Feem ntau hais lus, lub voj voos hollow seem muaj tus nqi siab nyob rau hauv kev sib piv nrog cov yeeb nkab round steel nyob rau hauv lwm yam kev mob, rau cov qub yuav muaj ntau raw khoom noj nyob rau hauv 2018.
