Ibyuma bya H ni ibikoresho byubaka imbaraga nyinshi hamwe nigice cyambukiranya inyuguti “H”. Ifite ibyiza byuburemere bworoshye, kubaka byoroshye, kuzigama ibikoresho no kuramba cyane. Igishushanyo cyacyo kidasanzwe cyambukiranya ibice cyiza cyane mubushobozi bwo kwikorera imitwaro no gutezimbere imiterere, kandi gikoreshwa cyane mumishinga yubatswe nkinyubako ndende, ibiraro, inganda zinganda nububiko. Ibisobanuro bitandukanye nubunini bwibyuma bya H birashobora gutoranywa no guhindurwa ukurikije umushinga wihariye ukeneye kubahiriza ibyangombwa bitandukanye byubaka.
HEA, HEB, na HEM nibisobanuro byibice bisanzwe bya IPE (I-beam).
ENH-Icyuma gisa nicyerekezo cyiburayi bisanzwe bya IPE (I-beam).
ENH-Icyuma gikozwe cyane gikoreshwa cyane kandi gifite uburyo bwiza bwo kunama, gukomera kwimiterere no kurwanya ruswa. Kubwibyo, ikoreshwa cyane mubwubatsi, gukora imashini, ibiraro, amato, ibyuma byubatswe hejuru nibindi.
Igipimo cy’amahanga E.NH-Icyuma gikozwe mu byuma bivuga ibyuma bya H byakozwe hakurikijwe amahame y’amahanga, ubusanzwe bivuga ibyuma bimeze nka H byakozwe hakurikijwe ibipimo by’Ubuyapani JIS cyangwa ASTM yo muri Amerika. Icyuma cya H ni ubwoko bwibyuma bifite "H" -ibice byambukiranya. Igice cyacyo cyerekana imiterere isa n’inyuguti y'Ikilatini “H” kandi ifite imbaraga zo kugonda no gutwara ibintu.
