Thaum nws los txog rau cov khoom siv hlau ua vaj tse,Cov U-channelsthiabC-channelsyog ob hom profiles uas siv ntau tshaj plaws hauv kev tsim kho thiab kev tsim khoom. Ob hom channels ua lub luag haujlwm tseem ceeb hauv ntau yam kev siv, tab sis lawv muaj cov yam ntxwv sib txawv uas ua rau lawv haum rau kev siv sib txawv. Kev nkag siab txog qhov sib txawv ntawm U-channels thiab C-channels yog qhov tseem ceeb rau cov engineers, architects, thiab cov neeg ua vaj tse xaiv cov khoom siv zoo rau lawv cov haujlwm.
Cov U-channels, feem ntau hu ua U-beams lossis U-sections, yog cov yam ntxwv los ntawm lawv cov duab U-shaped cross-section. Tus qauv tsim no muaj ob ceg ntsug txuas nrog los ntawm lub hauv paus kab rov tav, zoo li tsab ntawv "U". Cov sab qhib ntawm U-channel tuaj yeem txuas nrog lwm cov ntaub ntawv tau yooj yim, ua rau nws yog qhov kev xaiv ntau yam rau ntau yam kev siv.
Ntawm qhov tod tes, ibC-channel(tseem hu ua C-beam lossis C-section) muaj C-shaped cross-section. Zoo ib yam li U-channel, C-channel muaj ob ceg ntsug thiab ib lub hauv paus kab rov tav, tab sis daim di ncauj ntawm qhov kawg ntawm ob txhais ceg pom tseeb dua, ua rau nws muaj C-puab tshwj xeeb. Tus qauv tsim no muab lub zog thiab kev ruaj khov ntxiv, ua rau C-channel yog qhov kev xaiv nrov rau cov ntawv thov kev tsim kho.
Ib qho ntawm qhov sib txawv tseem ceeb ntawm U-channels thiab C-channels yog lawv lub zog thiab lub peev xwm thauj khoom. Vim lawv tsim, C-channels feem ntau suav tias muaj zog dua li U-channels. Lub di ncauj ntxiv rau ntawm qhov kawg ntawm C-channel ceg ua rau nws tsis kam khoov thiab ntswj, ua rau nws zoo tagnrho rau cov ntawv thov uas xav tau lub peev xwm thauj khoom siab.
Txawm hais tias tseem muaj zog, U-channel yuav tsis muab kev txhawb nqa zoo ib yam li C-channel. Txawm li cas los xij, nws txoj kev tsim qhib tso cai rau kev ywj pheej ntau dua hauv qee qhov kev siv, xws li thaum nws xav tau welded lossis bolted rau lwm yam khoom. Qhov kev xaiv ntawm ob qho feem ntau nyob ntawm qhov xav tau tshwj xeeb ntawm qhov project, suav nrog cov khoom thauj uas nws yuav tsum txhawb nqa thiab hom kev sib txuas xav tau.
Cov channel U thiabC-channelssiv dav hauv kev tsim kho, kev tsim khoom, thiab ntau yam kev siv hauv kev lag luam. U-channels feem ntau siv rau hauv cov ntawv thov uas xav tau kev daws teeb meem sib dua thiab ntau yam. Kev siv dav suav nrog kev ua thav duab, kev txhawb nqa, thiab ua kev txhawb nqa rau kev racking lossis khoom siv. Lawv tus qauv qhib yooj yim sib xyaw nrog lwm cov ntaub ntawv, ua rau lawv yog qhov kev xaiv nrov rau kev tsim khoom tshwj xeeb.
C-channels feem ntau siv rau hauv cov qauv siv xws li cov thav duab tsev, cov choj thiab cov tshuab hnyav vim lawv lub zog tshwj xeeb. Lawv muaj peev xwm tiv taus cov khoom hnyav, ua rau lawv zoo tagnrho rau kev siv hauv cov chaw uas muaj kev ruaj khov thiab kev ruaj khov. Tsis tas li ntawd,C-channelsfeem ntau yog siv los tsim cov ntaiv, cov brackets thiab lwm yam khoom siv uas xav tau lub thav duab muaj zog.
Hauv kev xaus lus, thaum ob qho tib si U-channels thiab C-channels ua lub luag haujlwm tseem ceeb hauv kev tsim kho thiab kev tsim khoom, lawv muaj qhov sib txawv thiab haum rau ntau daim ntawv thov. U-channels zoo tagnrho rau cov qauv sib dua thiab cov haujlwm tshwj xeeb vim lawv qhov kev hloov pauv thiab yooj yim ntawm kev sib txuas. Qhov sib piv, C-channels yog qhov nyiam rau cov ntawv thov hnyav dua vim lawv lub zog zoo dua thiab lub peev xwm thauj khoom. Kev nkag siab txog qhov sib txawv no yog qhov tseem ceeb rau kev xaiv hom channel zoo rau koj cov kev xav tau tshwj xeeb, kom ntseeg tau tias koj qhov project ua tiav thiab muaj kev nyab xeeb.
