Insimbi enezimbobo ucezu lweshidi lensimbi olugxivizwe, lwakhiwe, noma lwashaywa ukuze kwakhiwe iphethini yezimbobo, izikhala, kanye nokwakheka okuhlukahlukene kobuhle. Izinhlobonhlobo zezinsimbi zisetshenziswa enqubweni yensimbi yokubhoboza, ehlanganisa insimbi, i-aluminium, insimbi engagqwali, ithusi, ne-titanium. Nakuba inqubo yokubhoboza ithuthukisa ukubukeka kwezinsimbi, ineminye imiphumela ewusizo njengokuvikela nokucisha umsindo.

Izinhlobo zezinsimbi ezikhethelwe inqubo yokubhoboza zincike kusayizi wazo, ukujiya kwegeji, izinhlobo zezinto zokwakha, nokuthi zizosetshenziswa kanjani. Kunemikhawulo embalwa kumajamo angasetshenziswa futhi afaka izimbobo eziyindilinga, izikwele, ezifakiwe, nezinezinhlangothi ezine, ukusho ezimbalwa.
