Umbhobho wentsimbi yomthungo kunyeumbhobho wentsimbi ongenamthungozahlulwe ngokwefomu yokucubungula.Umbhobho wentsimbi yomthungo udityaniswe ngokubanzi.Umbhobho wensimbi ongenamthungo uneendlela ezimbini zokudweba okubandayo kunye nokuqengqeleka okushushu.Umbhobho we-carbon steel uhambelana nezinto eziphathekayo, kwaye umbhobho we-galvanized ungaphezulu kombhobho odibeneyo owenziwe emva kokuveliswa.

Ngokuqhelekileyo, iibhubhu zentsimbi ezingenamthungo zisetyenziselwa abo baneemfuno eziphezulu kwi-carrier carrier, ezifana noxinzelelo, indawo, ukugcinwa, ukubola kunye nobushushu.Imibhobho yentsimbi yomthungo isetyenziselwa abo banoxinzelelo oluphantsi kunye neemfuno zobushushu, njengemibhobho yamanzi asekhaya kunye nemibhobho yegesi.
