Izikulufu zokusetha ziyizingxenye ezibalulekile ezinhlelweni zokusebenza ezihlukahlukene zemishini nezobunjiniyela, ezidlala indima ebalulekile ekuvikeleni izingxenye ezijikelezayo noma ezishelelayo kumashafti. Izikulufu zethu ezisethiwe zenziwe ngobunono ukuze zilethe ukwethembeka okukhethekile nokuqina, okuqinisekisa ukuqiniswa okuqinile ezindaweni ezidinga kakhulu. Ngokugxila kubunjiniyela obunembayo, izikulufu zethu zokusetha zinikeza ukubamba okuvikelekile nokubamba okuqinile, okuzenza zilungele izinhlelo zokusebenza kuzo zonke izimboni ezifana nemishini, izimoto, ugesi, nokunye. Kungakhathaliseki ukuthi insimbi ye-carbon steel, insimbi engagqwali, ithusi, noma i-alloy steel, uhla lwethu olubanzi lwesethi yezikulufi lubhekelela izimfuneko zezinto ezihlukahlukene, ezithembisa ukusebenza okuphakeme nokuphila isikhathi eside. Khetha izikulufo zethu zesethi yekhwalithi engaxegi kanye nokuzinza okungantengantengi kuma-assemblies akho.
