Mu nganda zubaka zigenda zitera imbere, gukurikirana ibikoresho birambye kandi bitangiza ibidukikije ntabwo byigeze biba ngombwa. Mu gihe duhura n’ibibazo by’imihindagurikire y’ikirere no kugabanuka kw’umutungo, inganda zirimo kwerekeza ibitekerezo ku bisubizo bishya bidahuye gusa n’imiterere ahubwo binita ku bidukikije. Igisubizo kigenda gikundwa cyane nigiti cya H20 cyibiti, bakunze kwita H beam cyangwa I beam. Ibi bikoresho bidasanzwe byo kubaka ntabwo ari uburyo buhendutse bwo gukoresha ibyuma gakondo, ariko kandi byerekana intambwe ikomeye igana ahazaza heza h’inganda zubaka.
Ibiti bya H20 bikozwe muburyo butandukanye bwo kubaka, cyane cyane imishinga itwara imizigo. Mugihe ibiti byibyuma bizwiho ubushobozi bwo gutwara imitwaro myinshi, akenshi bizana nigiciro kinini cyibidukikije. Umusaruro wibyuma usaba ingufu nyinshi kandi byongera cyane imyuka ihumanya ikirere. Ibinyuranye, ibitiH beamtanga ubundi buryo burambye bugabanya ibiciro nibidukikije. Ibikomoka ku mashyamba acungwa neza, ibi biti ntibishobora kuvugururwa gusa ahubwo binashakisha karubone, bigatuma bahitamo ibidukikije.
Kimwe mu bintu byingenzi biranga ibiti bya H20 ni byinshi. Irashobora gukoreshwa mubikorwa bitandukanye byubwubatsi kuva aho gutura kugeza ku nyubako zubucuruzi. Ihindagurika rifasha abubatsi n'abubatsi gushyiramo ibikoresho birambye bitabangamiye igishushanyo mbonera cyangwa ubunyangamugayo. Byongeye kandi, uburemere bworoshye bwibiti H-beam byoroshya ubwikorezi nogushiraho, bikagabanya ibirenge bya karubone bijyanye nibikorwa byubwubatsi.
Nka sosiyete yiyemeje kwagura isoko ry’isi yose, twashinze isosiyete yohereza ibicuruzwa mu mahanga mu mwaka wa 2019. Kuva icyo gihe, twashyizeho umubano mwiza n’abakiriya mu bihugu bigera kuri 50, tubaha ibiti byiza bya H20 byo mu rwego rwo hejuru. Ibyo twiyemeje kuramba bigaragarira muri sisitemu yo guhuriza hamwe isoko, ituma dukura inkwi kubatanga ibicuruzwa byemewe bakurikiza imikorere y’amashyamba ashinzwe. Ibi ntabwo byemeza ubwiza bwibicuruzwa byacu gusa, ahubwo binashyigikira kurengera amashyamba n’ibinyabuzima bitandukanye.
Kwiyongera gukenerwa kubikoresho byubaka ibidukikije bitangiza ibidukikije birenze inzira gusa, birakenewe. Nkuko abubatsi benshi nabateza imbere bamenya akamaro ko kubaka ibikorwa birambye,H Ibitibiteganijwe ko bizaba inzira nyamukuru mu nganda. Ihuza imbaraga, ibintu byinshi hamwe nubucuti bwibidukikije, bigatuma ihitamo ryiza kubashaka kugabanya ingaruka zabo kubidukikije mugihe bagikora ibisubizo byiza.
Mu gusoza, ahazaza h'inganda zubaka ziri mu bikoresho bishyira imbere kuramba nta gutamba ubuziranenge. Ibiti by'ibiti bya H20 byerekana iterambere rigaragara muri iki cyerekezo, bitanga ubundi buryo bwiza bwo gukoresha ibyuma gakondo. Mugihe dukomeje guhanga udushya no guhuza imiterere yimiterere yinganda zubaka, biragaragara ko ibiti H-ibiti bizagira uruhare runini mukubaka ejo hazaza heza. Muguhitamo ibikoresho bitangiza ibidukikije dushobora gutanga umusanzu mubuzima bwiza mugihe tugikeneye ibyifuzo byubwubatsi bugezweho. Emera ejo hazaza h'ubwubatsi hifashishijwe ibiti bya H20 kandi wifatanye natwe mukugira ingaruka nziza kubidukikije.
