Ibyuma byiza cyane byakozwe mu buhanga bwa sima byakozwe mu byuma
Umugozi w'icyuma ushyizwemo imbaraga ni insinga y'icyuma igizwe n'insinga 2, 3, 7 cyangwa 19 zikomeye cyane, kandi yavuwe igabanya stress (gutera imbaraga), ikwiriye gukoreshwa muri beto ishyizwemo imbaraga cyangwa indi mirimo isa nayo.
Ibiranga by'ingenzi imigozi y'icyuma ishyirwamo imbaraga ni imbaraga nyinshi, ubushobozi bwo kuruhuka neza, kandi igororotse iyo ifunguye. Ingufu zisanzwe zo gukurura ni 1860 MPa, kandi hari imbaraga nka 1720, 1770, 1960, 2000, na 2100 MPa. Ingufu z'iki cyuma nazo ni nyinshi cyane.
Insinga y'icyuma cya karuboni nyinshi ikururwa mu nsinga z'icyuma zikonje nyuma yo gutunganya ubuso, hanyuma insinga z'icyuma nyinshi zigahindurwamo imigozi hakurikijwe imiterere y'umugozi w'icyuma, hanyuma zigakorwa binyuze mu nzira yo kugabanya stress. Kugira ngo wongere igihe cyo kuramba, insinga y'icyuma ishobora kugira icyuma cyangwa idafite icyuma cyangwa irangi, nko gukaranga, gusiga epoxy, nibindi. Kugira ngo wongere imbaraga zo gufatana na sima, ubuso bushobora kugira utudomo n'ibindi. Umugozi w'icyuma wabumbwe ukorwa nyuma yo gukaranga, imiterere iba ikomeye kandi urwego rw'ubuso rukwiriye cyane gufatirwa. Kugira ngo ukore imigozi y'icyuma idafatanye (imigozi y'icyuma idafatanye) koresha imigozi isanzwe yabumbwe, isizwe amavuta arwanya ingese cyangwa ishashi ya parafini, hanyuma ipfundikwe na polyethylene ifite ubucucike bwinshi (HDPE).
