C iziteshi, ezaziwa nangokuthi C purlins noma C izingxenye, izingxenye zesakhiwo ezisetshenziswa kabanzi kumaphrojekthi wokwakha. Lawa maphrofayili ensimbi ahlala isikhathi eside futhi ahlukahlukene anezinhlelo zokusebenza ezahlukahlukene futhi avame ukuqashwa njengohlelo lokusekela ezakhiweni noma njengamalungu enza izinhlaka. Kulesi sihloko, sizoxoxa ngomsebenzi kanye nezinhlobo ezahlukene zeziteshi ze-C.
Umsebenzi oyinhloko wamashaneli C ukuhlinzeka ngosekelo lwesakhiwo. Ngokusabalalisa umthwalo ngokulinganayo, basiza ukuthuthukisa amandla nokuzinza kwesakhiwo. Amashaneli C avame ukusetshenziswa njengemishayo, amakholomu, nama-purlins. Njengemishayo, iyingxenye ebalulekile yohlaka, isekela isisindo sesakhiwo futhi isidlulisele esisekelweni. Angasetshenziswa futhi njengamakholomu, adlala indima ebalulekile ekusekeleni uphahla lwesakhiwo. Ukwengeza, iziteshi ze-C zingasebenza njengama-purlins, zinikeze ukusekelwa kwesakhiwo endaweni yophahla futhi zidlulisele isisindo ezindongeni ezithwala umthwalo.
C iziteshiziza ngezinhlobo ezahlukene, ngayinye isebenzela injongo ethile. Ezinye izinhlobo ezijwayelekile zifaka phakathi okujwayelekile (noma okujwayelekile), i-flange eyehlelayo, neziteshi ze-strut C. Iziteshi ezijwayelekile C, ezaziwa nangokuthi iziteshi zendabuko C, zinama-flange womabili anobude obulinganayo. Zisetshenziswa kakhulu ekwakhiweni futhi zifaneleka ngokukhethekile izinhlelo zokusebenza lapho kulindeleke khona imithwalo elula. Ngakolunye uhlangothi, iziteshi ze-flange ezitshekile ze-C, zine-flange eyodwa ubude kunomunye, zidala umphumela owehlelayo. Lo mklamo ukhulisa umthamo wokuthwala futhi uvame ukusetshenziswa kumaphrojekthi ezimboni. Iziteshi ze-Strut C zisetshenziswa kakhulu ekufakweni kukagesi nokomshini. Zinezimbobo ngaphezulu, ezivumela ukuthi zifakwe kalula ezindongeni, phansi, noma ophahleni.
Ngokungeziwe ezinhlotsheni ezihlukahlukene, iziteshi ze-C nazo ziza ngobukhulu obuhlukahlukene nobukhulu ukuze zihlangabezane nezidingo ezithile zephrojekthi. Ubukhulu besiteshi esingu-C bunqunywa ubude baso, ububanzi, nesisindo ngonyawo ngalunye. Lezi zilinganiso zikhomba umthamo wokulayisha kanye nekhono lokusekela lesiteshi. Lapho ukhetha isiteshi esingu-C, kubalulekile ukucabangela izici ezifana nobude besikhathi, uhlobo lomthwalo, nezimo zemvelo.
Izinzuzo zokusebenzisa iziteshi ze-C ziningi. Okokuqala, alula, okwenza kube lula ukuwaphatha nokuwafaka. Okwesibili, ukuguquguquka kwazo kuzivumela ukuthi zisetshenziswe ezinhlobonhlobo zezicelo, kusukela ezakhiweni zokuhlala kuya kumaphrojekthi ezimboni. Okwesithathu,C iziteshinikeza amandla aphezulu esakhiwo ngenkathi idinga ukulungiswa okuncane. Ziyakwazi futhi ukumelana nokugqwala, ziqinisekisa ukuqina nokuphila isikhathi eside.
Ekuphetheni,C iziteshiukudlala indima ebalulekile kumaphrojekthi wokwakha, ukuhlinzeka ngosizo lwesakhiwo kanye nokuthuthukisa amandla kanye nokuzinza kwesakhiwo. Ziza ngezinhlobo ezahlukene, osayizi, kanye nobukhulu ukuze zivumelane nezinhlelo zokusebenza nezimfuneko ezahlukene. Kungakhathaliseki ukuthi isetshenziswa njengemishayo, amakholomu, noma ama-purlins, iziteshi C zinikeza ukuguquguquka, ukuqina, kanye nokuzifaka kalula. Imvelo yabo engasindi, umthamo omkhulu wokuthwala umthwalo, nokumelana nokugqwala kubenza babe ukukhetha okuhle kakhulu kwezidingo ezahlukahlukene zokwakha.
