Insimbi yesakhiwo isigaba sensimbi esetshenziswa njengempahla yokwakha ekwenzeni izimo zensimbi yesakhiwo.Umumo wensimbi yesakhiwo iphrofayili, eyakhiwe ngesigaba esithile esiphambene futhi elandela izindinganiso ezithile zokwakheka kwamakhemikhali kanye nezakhiwo zemishini.Izimo zensimbi yesakhiwo, osayizi, ukwakheka, amandla, izindlela zokulondoloza, njll., kulawulwa ngezindinganiso emazweni amaningi anezimboni.

Amalungu ensimbi yesakhiwo, njengama-I-beams, anezikhathi eziphakeme zesibili zendawo, eziwavumela ukuba aqine kakhulu maqondana nendawo yawo ephambanayo.

Izimo ezijwayelekile zesakhiwo

Umumo otholakalayo uchazwa kumazinga amaningi ashicilelwe emhlabeni wonke, futhi inqwaba yezingxenye ezinqamulayo zochwepheshe kanye nokuphathelene nazo ziyatholakala.

·I-I-beam (i-cross-section emise okuka-I – eBrithani lokhu kuhlanganisa i-Universal Beams (UB) kanye namakholomu Endawo Yonke (UC); eYurophu ihlanganisa i-IPE, HE, HL, HD nezinye izigaba; e-US ihlanganisa i-Wide Flange (izigaba ze-WF noma i-W-Shape) kanye no-H)

·I-Z-Shape (uhhafu we-flange ezindaweni eziphambene)

·I-HSS-Shape (Isigaba sesakhiwo esingenalutho esaziwa nangokuthi i-SHS (ingxenye yesakhiwo esingenalutho) futhi kufaka phakathi isikwele, unxande, isiyingi (ipayipi) kanye nezingxenye eziphambanayo eziyi-elliptical)

·I-engeli (isiqephu esiphambanayo esimise okuka-L)

·Ishaneli yesakhiwo, noma i-C-beam, noma i-C cross-section

·I-Tee (isiphambano esimise okuka-T)

·Iphrofayela kaloliwe (i-asymmetrical I-beam)

·Ujantshi wesitimela

·Isitimela se-Vignoles

·Umzila wesitimela we-Flanged

·Umzila wesitimela ogobile

·Ibha, ucezu lwensimbi, i-rectangular cross sectioned (flat) futhi ende, kodwa hhayi ububanzi kangangokuthi ibizwa ngokuthi ishidi.

·Induku, ucezu lwensimbi oluyindilinga noma oluyisikwele nolude, bheka ne-rebar nedowel.

·Ipuleti, amashidi ensimbi anogqinsi kuno-6 mm noma 1⁄4 phakathi.

·Vula i-web steel joist

Nakuba izingxenye eziningi zenziwa ngokuginqika okushisayo noma okubandayo, ezinye zenziwa ngokushisela ndawonye izingcwecwe eziyisicaba noma ezigobile (ngokwesibonelo, izingxenye eziyizigodi ezinkulu eziyindilinga zenziwe ngepuleti eliyisicaba eligotshwe libe yindilinga futhi line-welded).
