Extrudate nikintu gifite geometrie runaka ikozwe mubyuma cyangwa ibyuma nibikoresho bifite imbaraga nubukomezi (nka plastiki, aluminium, fibre yibirahure, nibindi) binyuze mukuzunguruka, gusohora, guta nibindi bikorwa.
Itondekanya ryicyuma cyicyiciro: ukurikije ubwiza butandukanye bwo gushonga ibyuma, ibyuma byigabanyijemo ibice bisanzwe byicyuma nicyiciro cyiza cyane.Ukurikije urutonde rwibicuruzwa biriho ubu, ibyuma bisanzwe bigabanyijemo ibice binini, ibyuma biciriritse nicyuma gito.Ukurikije imiterere yacyo, ibyuma bisanzwe birashobora kugabanywamo I-beam, ibyuma byumuyoboro, ibyuma byinguni, ibyuma bya H-igice, ibyuma bizunguruka, nibindi.
