Isakhiwo sensimbiisakhiwo esakhiwe ngezinto zensimbi, okungenye yezinhlobo eziyinhloko zezakhiwo zokwakha. Isakhiwo ngokuyinhloko sakhiwe ngemishayo, amakholomu ensimbi, ama-trusses ensimbi nezinye izakhi ezenziwe ngensimbi enephrofayili kanye namapuleti ensimbi. Yamukela i-silanization, i-phosphating ehlanzekile ye-manganese, ukuwasha nokomisa, i-galvanizing kanye nezinye izinqubo zokususa ukugqwala kanye nezinqubo zokuvimbela ukugqwala. Izingxenye noma izingxenye ngokuvamile zixhunywe nge-welding, ama-bolts noma ama-rivets. Ngenxa yesisindo sayo esilula nokwakhiwa kalula, isetshenziswa kabanzi ezakhiweni ezinkulu zefektri, izinkundla zemidlalo, nasezindaweni eziphakeme kakhulu. Izakhiwo zensimbi zisengozini yokugqwala. Ngokuvamile, izakhiwo zensimbi zidinga ukwehliswa, zifakwe uthayela noma zipendwe, futhi zigcinwe njalo.
