Icyuma C igice gitunganywa nimpapuro zishyushye kandi zirakonjeshwa hakoreshejwe ibyuma byimbaraga nyinshi kugirango ugabanye uburemere mugihe ubushobozi bwa buri gice.Zikoreshwa mugisenge no kurukuta kugirango zishyigikire igisenge hamwe nurukuta.Gereranije nicyuma cyumuyoboro, C igice cyicyuma cyicyuma gishobora kuzigama imyanda 30%, kandi ifite urukuta ruto, uburemere bworoshye, imikorere myiza yicyiciro hamwe nimbaraga zikomeye. C ibyuma bihita bitunganywa bigakorwa na mashini ikora C.Imashini ikora ibyuma bya C irashobora guhita irangiza C ikora ibyuma ukurikije ubunini bwa C bwatanzwe.
C igice cyicyuma cyitwa purlins kigabanijwemo ibisobanuro bya 120.140.160, 180, 200,220, 250 nibindi ukurikije uburebure.Uburebure bushobora kugenwa ukurikije igishushanyo mbonera, ariko urebye imiterere yubwikorezi nogushiraho, uburebure bwose ntabwo burenga metero 12.
