Xa kufikwa kwizinto zentsimbi ezakhiweyo,Iitshaneli ze-UkwayeIitshaneli ze-Czezona zimbini zezona zisetyenziswa kakhulu ekwakheni nasekuveliseni. Zombini ezi ntlobo zemijelo zidlala indima ebalulekileyo kwiindlela ezahlukeneyo zokusebenza, kodwa zineempawu ezahlukeneyo ezenza zifaneleke kwiindlela ezahlukeneyo. Ukuqonda umahluko phakathi kwemijelo ye-U kunye nemijelo ye-C kubalulekile kwiinjineli, abakhi bezakhiwo, kunye nabakhi ukuba bakhethe izinto ezifanelekileyo kwiiprojekthi zabo.
Iitshaneli ze-U, ezibizwa ngokuba zii-U-beams okanye ii-U-sections, zibonakaliswa yi-cross-section yazo enomfanekiso we-U. Olu yilo lunemilenze emibini ethe nkqo edityaniswe ngesiseko esithe tye, esifana nonobumba "U". Amacala avulekileyo etshaneli ye-U anokudityaniswa ngokulula nezinye izinto, nto leyo eyenza ukuba kube lukhetho olusebenzisekayo kwiintlobo ngeentlobo zezicelo.
Kwelinye icala,Itshaneli ye-C(ekwabizwa ngokuba yi-C-beam okanye i-C-section) ine-cross-section emile okwe-C. Njenge-U-channel, i-C-channel inemilenze emibini ethe nkqo kunye nesiseko esithe tye, kodwa umlebe osekupheleni kwemilenze ubonakala ngakumbi, nto leyo enika imo eyahlukileyo ye-C. Olu yilo lubonelela ngamandla ongezelelweyo kunye nokuzinza, nto leyo eyenza i-C-channel ibe lukhetho oludumileyo lokusetyenziswa kwesakhiwo.
Omnye womahluko ophambili phakathi kwee-U-channels kunye nee-C-channels ngamandla azo kunye nomthamo wazo wokuthwala umthwalo. Ngenxa yoyilo lwazo, ii-C-channels zihlala zithathwa njengezinamandla kunee-U-channels. Umlebe owongeziweyo ekupheleni kwemilenze ye-C-channel uyawonyusa ukumelana kwawo nokugoba nokujika, nto leyo eyenza ukuba ilungele ukusetyenziswa okudinga umthamo ophezulu wokuthwala umthwalo.
Nangona isaqinile, i-U-channel isenokungaboneleli ngenqanaba elifanayo lenkxaso njenge-C-channel. Nangona kunjalo, uyilo lwayo oluvulekileyo luvumela ukuguquguquka okukhulu kwiindlela ezithile zokusebenza, njengaxa kufuneka idityaniswe okanye ibotshelelwe kwezinye izinto. Ukukhetha phakathi kwezi zimbini kudla ngokuxhomekeka kwiimfuno ezithile zeprojekthi, kubandakanya imithwalo ekufuneka iyixhase kunye nohlobo loqhagamshelo olufunekayo.
Iitshaneli ze-U kunyeIitshaneli ze-Czisetyenziswa kakhulu ekwakheni, kwimveliso, nakwiindlela ezahlukeneyo zokusebenza kwimizi-mveliso. Ii-U-channels zihlala zisetyenziswa kwizicelo ezifuna isisombululo esikhaphukhaphu nesinokuguquguquka. Ukusetyenziswa okuqhelekileyo kubandakanya ukubumba, ukuxhasa, kunye nokuxhasa iiraki okanye izixhobo. Uyilo lwazo oluvulekileyo ludibana lula nezinye izixhobo, nto leyo eyenza ukuba zibe lukhetho oludumileyo lokwenza ngokwezifiso.
Ii-C-channels zihlala zisetyenziswa kwizicelo zesakhiwo ezifana nezakhelo zokwakha, iibhulorho kunye noomatshini abanzima ngenxa yamandla azo angaqhelekanga. Ziyakwazi ukumelana nemithwalo enzima, nto leyo ezenza zibe zilungele ukusetyenziswa kwiindawo apho ukuqina kunye nozinzo kubalulekile. Ukongeza,Iitshaneli ze-Czisetyenziswa rhoqo ukwakha iirelingi, iibrakethi kunye nezinye izinto zokwakha ezifuna isakhelo esomeleleyo.
Ngamafutshane, nangona zombini ii-U-channels kunye nee-C-channels zidlala indima ebalulekileyo ekwakheni nasekwenzeni, zinezahluko ezahlukeneyo kwaye zifanelekile kwiindlela ezahlukeneyo zokusebenza. Ii-U-channels zilungele izakhiwo ezilula kunye neeprojekthi ezenziwe ngokwezifiso ngenxa yokuguquguquka kwazo kunye nokulula kokunxibelelana. Ngokwahlukileyo koko, ii-C-channels zikhethwa kwiindlela ezinzima zokusebenza ngenxa yamandla azo aphezulu kunye nomthamo wokuthwala umthwalo. Ukuqonda la mahluko kubalulekile ekukhetheni uhlobo olufanelekileyo lwetshaneli oluhambelana neemfuno zakho ezithile, ukuqinisekisa ukuba iprojekthi yakho iphumelele kwaye ikhuselekile.
