Kugenwa n'amagambo
• Muri Amerika,Icyuma I Beams bikunze kugaragara ukoresheje ubujyakuzimu n'uburemere bw'igiti.Kurugero, urumuri "W10x22" rufite hafi 10 muri (25 cm) zubujyakuzimu (uburebure bwizina bwa I-beam kuva mumaso yinyuma ya flange imwe kugeza mumaso yinyuma yizindi flange) kandi ipima 22 lb / ft (33 kg / m).Twabibutsa ko igice kinini cya flange gitandukana bitewe nuburebure bwizina ryabo.Kubireba urukurikirane rwa W14, birashobora kuba byimbitse nka 22.84 muri (cm 58.0).
• Muri Mexico, ibyuma I-ibiti byitwa IR kandi bikunze kugaragara ukoresheje ubujyakuzimu n'uburemere bw'igiti mu magambo.Kurugero, urumuri "IR250x33" rufite uburebure bwa mm 250 (9.8 in) mubwimbye (uburebure bwa I-beam kuva mumaso yinyuma ya flange imwe kugeza mumaso yinyuma yizindi flange) kandi ipima hafi kg 33 / m (22 lb / ft).
