Irashobora kugabanywamo ibyiciro bine:a. Umwirondoro, b. Urupapuro, c. Umuyoboro, na d. Ibicuruzwa.
a. Umwirondoro:
Gari ya moshi iremereye, ibyuma bya gari ya moshi (harimo na gari ya moshi) bifite uburemere burenga kg 30 kuri metero;
gariyamoshi yoroheje, ibyuma byuma bifite uburemere bwa kg 30 cyangwa munsi ya metero.
Icyuma kinini cyicyuma: ibyuma rusange bizunguruka ibyuma, ibyuma kare, ibyuma biringaniye, ibyuma bitandatu, I-beam, ibyuma byumuyoboro, ibyuma bingana kandi bingana ibyuma bingana na rebar, nibindi.Igabanyijemo ibyuma binini, bito n'ibiciriritse ukurikije igipimo
Umugozi: Ibyuma bizunguruka hamwe ninsinga zifite diameter ya mm 5-10
Igice cyubukonje: Igice cyakozwe nubukonje bukora ibyuma cyangwa ibyuma
Umwirondoro wo mu rwego rwo hejuru:ibyuma byujuje ubuziranenge ibyuma bizunguruka, ibyuma kare, ibyuma biringaniye, ibyuma bitandatu, nibindi
b. Isahani
Ibyuma byoroheje, ibyuma bifite uburebure bwa mm 4 cyangwa munsi yayo
Isahani yibyibushye, ifite uburebure burenze mm 4.Irashobora kugabanywamo isahani yo hagati (uburebure burenze 4mm na munsi ya 20mm),isahani yuzuye (umubyimba urenze 20mm na munsi ya 60mm), isahani yimbitse (uburebure burenze 60mm)
Icyuma cyuma, nanone cyitwa strip strip, mubyukuri nicyapa kirekire, gito cyoroshye gitangwa muri coil
Amashanyarazi ya silicon yamashanyarazi, nanone bita urupapuro rwicyuma cya silicon cyangwa urupapuro rwicyuma
c. Umuyoboro:
Umuyoboro w'icyuma udafite ikizinga, umuyoboro w'icyuma udafite icyerekezo ukorwa no kuzunguruka bishyushye, gushushanya bishyushye-gushushanya cyangwa gukata
Gusudira imiyoboro y'ibyuma, kugorora ibyuma cyangwa imirongo y'ibyuma, hanyuma gusudira imiyoboro yakozwe
d. ibicuruzwa byibyuma Harimo insinga zicyuma, umugozi wicyuma, insinga zicyuma, nibindi
