Ibikoresho bya S355J0H bifite imiterere yubukorikori ko imbaraga ntoya yumusaruro ari 355MPa mugihe uburebure bwurukuta butarenze mm 16 kandi bujuje imbaraga nkeya za 27J kuri 0 ℃.
B. nigiciro cyo gupiganwa.
Icyitonderwa: Ibisabwa byose muriyi nyandiko biranakoreshwa kuri EN 10210.
Uburebure bw'urukuta ≤120mm.
Kuzenguruka (HFCHS): Hanze ya diameter kugera kuri mm 2500;
Ikibanza (HFRHS): Hanze ibipimo bigera kuri mm 800 x 800 mm;
Urukiramende (HFRHS): Hanze y'ibipimo bigera kuri mm 750 x 500 mm;
Elliptique (HFEHS): Hanze ibipimo bigera kuri 500 mm x 250 mm.

Ibikoresho byerekanwe muri BS EN 10210 bishingiye ku mbaraga zabo ntoya ku musaruro wa 16mm z'urukuta hamwe n'ingaruka z'ubushyuhe bwihariye.Imbaraga z'umusaruro, imbaraga zingana, no kurambura BS EN 10210 S355J0H bigabanuka uko uburebure bwurukuta bwiyongera.
BS EN 10210 yemerera umusaruro ukoresheje uburyo butandukanye bwo gukora, mubisanzwe harimo kashe, LSAW, SSAW, na ERW yo gusudira.
Hasi ni urutonde rwubunini kubikorwa bisanzwe.
Ugereranije haruguru, urashobora kubona ko umuyoboro wicyuma udafite kashe ufite inyungu yihariye mugukora umuyoboro wibyuma bikikijwe cyane, cyane cyane umuyoboro muto wa diameter ufite umubyimba muto, ariko ubunini bwawo buzaba buke.Niba ukeneye gukora imiyoboro yicyuma ifite diameter irenga 660mm, bizagorana.
Umuyoboro wirabura
Ibi bivuga umuyoboro wibyuma utabanje kuvura hejuru.
Kwirinda by'agateganyo
Kugira ngo wirinde kwangirika kw'imiyoboro y'icyuma mugihe cyo kubika, gutwara, cyangwa kuyishyiraho, uburyo rusange ni ugupfuka hejuru y'umuyoboro ukoresheje irangi cyangwa irangi.
Kurwanya ruswa
Hariho ubwoko bwinshi bwo kurwanya ruswa, harimo irangi, FBE,3LPE, na galvanised.Buri bwoko bwo gutwikira bufite ibintu byihariye nibidukikije bikoreshwa.Ruswa n'ingese birashobora kwirindwa neza ukoresheje uburyo bubereye bwo kurwanya ruswa hejuru yicyuma.
EN 10210 Amashanyarazi ashyushye ashyushye hejuru yicyuma agomba kuba yujuje ibyangombwa bisabwa na EN ISO 1461.

Kuva yashingwa mu 2014, Botop Steel yabaye iyambere mu gutanga imiyoboro ya karubone mu majyaruguru y’Ubushinwa, izwiho serivisi nziza, ibicuruzwa byiza, ndetse n’ibisubizo byuzuye.
Isosiyete itanga imiyoboro inyuranye y’ibyuma bya karubone n’ibicuruzwa bifitanye isano na byo, birimo icyuma, ERW, LSAW, hamwe n’icyuma cya SSAW, ndetse n’umurongo wuzuye w’ibikoresho bya flanges na flanges.Ibicuruzwa byayo bidasanzwe birimo kandi amavuta yo mu rwego rwo hejuru hamwe na austenitis ibyuma bitagira umuyonga, bigenewe guhuza ibyifuzo byimishinga itandukanye.
Ibindi bicuruzwa bifitanye isano:
Twandikire kubitekerezo byubusa no kugisha inama umushinga wawe.
