русский C-channels thiab U-channels yog ob hom dov steel profiles siv hauv kev tsim kho thiab kev tsim vaj tsev, tab sis lawv muaj cov duab sib txawv thiab cov yam ntxwv. Qhov sib txawv tseem ceeb ntawm lawv yog lawv cov duab sib luag:
1.C-Channel (C-Section):
- Ib tug C-channel muaj ib tug ntoo khaub lig-sectional duab uas zoo li tsab ntawv "C." Nws muaj lub tiaj tiaj tiaj (lub vev xaib) thiab ob qhov txuas txuas ntxiv (cov flanges) ntawm ob sab. Cov flanges tuaj yeem taw qhia sab nraud (qhib sab) lossis sab hauv (kaw sab) nyob ntawm daim ntawv thov tshwj xeeb.
- C-channels feem ntau yog siv rau cov txheej txheem framing, tshwj xeeb tshaj yog nyob rau hauv cov kev siv uas yuav tsum tau ib tug beam los yog kab rov tav kev txhawb nqa. Cov flanges muab lub zog thiab rigidity, thaum qhib los yog kaw sab yuav siv tau rau mounting los yog txuas.
2.U-Channel (U-Section):
- Ib qho U-channel, ntawm qhov tod tes, muaj qhov sib tshooj uas zoo ib yam li tsab ntawv "U." Nws muaj ib lub tiaj tiaj hauv qab (lub vev xaib) nrog ob qhov txuas txuas ntxiv (cov ceg) ntawm ob sab. Ob txhais ceg yog parallel rau ib leeg thiab feem ntau muaj qhov sib npaug.
- U-channels feem ntau yog siv rau cov ntawv thov uas yuav tsum muaj kev tiv thaiv ntug los yog ib qho kev thaiv, xws li tuav thiab tuav cov npoo ntawm cov iav vaj huam sib luag, tuav cov npoo ntawm cov ntawv hlau, los yog muab kev tiv thaiv los yog cov ciam teb zoo nkauj.
Hauv cov ntsiab lus, C-channels feem ntau yog siv rau kev tsim qauv, xws li thav duab thiab kev txhawb nqa kab teeb, vim tias lawv cov duab muab lub zog thiab rigidity. U-channels, nrog lawv cov U-shaped profile, zoo dua rau cov ntawv thov uas xav tau kev tiv thaiv ntug, ntim, lossis ciam teb. Qhov kev xaiv ntawm C-channel thiab U-channel nyob ntawm qhov kev xav tau tshwj xeeb ntawm qhov project thiab daim ntawv thov npaj.
