Ikhoyili eqengqelekayo eshushu ibhekisa ekucinezeleni iibhilithi kubunzima obufunwayo bentsimbi kumaqondo obushushu aphezulu. Kwi-hot rolling, intsimbi iqengqeleka emva kokufudunyezwa kwimeko yeplastiki, kwaye umphezulu unokuba ne-oxidized kwaye urhabaxa. Iikhoyili ezishushu ezigoqiweyo zihlala zinemilinganiselo emikhulu yokunyamezelana kunye namandla aphantsi kunye nobulukhuni, kwaye zifanelekile kwizakhiwo zokwakha, amacandelo oomatshini kwimveliso, imibhobho kunye nezikhongozeli.
