Imiyoboro y'icyuma idafite umwanya munini ifite umwanya munini mu nganda zigezweho kandi ikoreshwa cyane mu bwubatsi, gukora imashini, peteroli ndetse n’izindi nzego.EN 10210byerekana neza imiyoboro idafite ibyuma byubatswe, muri byo BS EN 10210-1 ni ibisobanuro byihariye kubishyushye bishyushye bitavanze kandi bifite ibyuma byiza byubatswe. Amanota asanzwe muriki gipimo arimo S235GRH, S275JOH, S275J2H, S355JOH na S355J2H.

Ubwa mbere, S235GRH nicyuma cyibanze cyibanze, gikoreshwa cyane mubice byubatswe munsi yubushyuhe buke nubushyuhe bwicyumba. Nimbaraga zitanga umusaruro wa 235MPa, ifite gusudira neza hamwe nubukonje bukonje, kandi ikwiranye nubwubatsi rusange nubukanishi.

Ibikurikira ni S275JOH na S275J2H. S275JOH ifite ubukana bwiza kuri -20 ℃ nimbaraga zitanga umusaruro wa 275MPa, kandi ubusanzwe ikoreshwa mubwubatsi no kubaka imishinga yikiraro ifite imitwaro iciriritse. S275J2H ifite ingaruka nziza zikomeye kuri -20 and, kandi irakwiriye ibice byubaka bisaba umutekano muke.

S355JOHnaS355J2Hni ibyuma bikomeye. S355JOH ifite ubukana buhebuje haba mubushyuhe bwicyumba nubushyuhe buke (-20 ℃), ifite umusaruro wa 355MPa, kandi ikoreshwa cyane mumishinga ihangayikishije cyane kandi ikomeye mubikorwa byubaka, nk'inyubako ndende n'ibiraro binini. S355J2H ifite ingaruka zikomeye kuri -20 and, kandi irakwiriye ahantu hakonje cyane cyangwa imishinga isaba umutekano wongeyeho.

Ikigereranyo cya EN 10210 ntigisobanura neza gusa imiterere yimiti nubukanishi bwimiyoboro yicyuma, ahubwo inashyira ahagaragara ibisabwa byihariye byo kwihanganira ibipimo, ubwiza bwubuso, ibizamini bidasenya, nibindi. Ibi byerekana ko imiyoboro yicyuma ihoraho kandi yizewe Koresha.

Imiyoboro idafite ibyuma ikozwe nubuhanga bushyushye, bubaha imiterere yubukanishi bwiza kandi bwuzuye. Igikorwa gishyushye kirashobora gukuraho imihangayiko imbere yicyuma, kunoza imiterere yubuyobozi bwicyuma, no kuzamura imikorere yuzuye. Ugereranije nu miyoboro y'icyuma isudira, imiyoboro idafite ibyuma ifite imbaraga zo gukomeretsa, kunama no gukomera, kandi birakwiriye gushyigikirwa no gutwara ibintu mu bihe bitandukanye byakazi.

Muri rusange, imiyoboro idafite ibyuma ikorwa ikurikije ibipimo bya EN 10210 yerekana imikorere myiza mubwubatsi n’inganda. Imiyoboro y'ibyuma by'amanota nka S235GRH, S275JOH, S275J2H, S355JOH, na S355J2H ifite imiterere yabyo kandi irashobora guhaza ibikenewe mumishinga itandukanye. Gukoresha kwinshi ntigutezimbere ubwiza numutekano byimishinga gusa, ahubwo binateza imbere iterambere no guhanga udushya twikoranabuhanga ryibikoresho. Guhitamo imiyoboro idafite ibyuma byerekana amanota hamwe nibisobanuro ni ngombwa kugirango habeho ituze rirambye n’inyungu zubukungu byimishinga.
