Umuyoboro w'icyuma wa EN 10219 S355J0H ni ibikoresho bikomeye kandi birwanya ingese, bikwiranye neza n'inyubako nyinshi n'ubwubatsi, harimo n'ibikoreshwa mu miyoboro.
1. Ikirundo cy'imiyoboro: Umuyoboro w'icyuma wa S355J0H ukwiriye cyane gukoreshwa nk'imirongo y'ifatizo bitewe n'imbaraga zawo no kudatwarwa n'ingufu kandi ukoreshwa cyane mu kubaka ibiti by'amazi, ibiraro, ishingiro ry'inyubako, n'indi mishinga isaba ishingiro rirerire.
2. Inyubako z'inyubako: Ikoreshwa cyane ku bice nk'imiterere y'amagufwa, inkingi zishyigikira, n'imiringa y'inyubako.
3. Gutwara umuyoboro w'amazi: Irakwiriye kandi gukoreshwa nk'umuyoboro wo gutwara peteroli na gaze mu ntera ndende. Ariko, akenshi iratwikirwa kugira ngo yongere igihe cyo kuyikoresha, urugero: 3LPE, FBE, galvanized, nibindi.
4. Imashini z'ubwubatsi: Ishobora gukoreshwa mu gukora udukingirizo n'ibice by'imashini zitandukanye z'ubwubatsi.
5. Ibigo bya leta: nk'aho gushyira imyenda mu bibuga by'imikino n'izindi nyubako zifasha ibikorwa binini bya leta.
EN 10210 S355J0H: Igice cy'ububobere cyo gukora inyubako zisukwaho ubushyuhe. Nubwo ahanini gikoreshwa mu gukora ubushyuhe, imiterere yabyo ya shimi n'imiterere ya mekanike bisa n'ibya S355J0H kandi gishobora gukoreshwa nk'ibikoresho bingana neza.
ASTM A500 Icyiciro C: Ikoreshwa mu gukora imiyoboro ivanze cyangwa ikozwe mu buryo bukonje, kare, n'urukiramende ikozwe mu buryo buvanze cyangwa bukozwe mu buryo bukonje kugira ngo ikoreshwe mu nyubako. ASTM A500 Grade C itanga umusaruro umwe n'imbaraga zo gukurura ku nyubako z'ubwubatsi n'iz'imashini.
CSA G40.21 350W: Iyi ni ibisobanuro by’ishyirahamwe ry’ibipimo bya Kanada bikubiyemo ubwoko bwinshi bw’ibyuma by’imiterere. Icyuma cya 350W gifite umusaruro n’imbaraga zo gukurura nk’iza S355J0H.
JIS G3466 STKR490: Iki ni igikoresho cy'umuyoboro wa kare n'urukiramende gikoreshwa mu bwubatsi nk'uko bivugwa mu Ishyirahamwe ry'Abayapani ry'Inganda (JIS). Kirakwiriye inyubako n'ibikorwa bya mekanike.
Kuva yashingwa mu 2014,Botop Steelyabaye ikigo gikomeye mu kugurisha imiyoboro y'icyuma cya karuboni mu majyaruguru y'Ubushinwa, kizwiho gutanga serivisi nziza, ibicuruzwa byiza, n'ibisubizo byuzuye.
Iyi kompanyi itanga imiyoboro itandukanye y’icyuma cya karuboni n’ibindi bifitanye isano, birimo imiyoboro y’icyuma idakora neza, ERW, LSAW, na SSAW, ndetse n’urutonde rwuzuye rw’imiyoboro n’ibice bifunganye. Ibicuruzwa byayo byihariye birimo kandi alloys nziza n’ibyuma bitarangirika bya austenitic, byakozwe kugira ngo bihuze n’ibikenewe mu mishinga itandukanye y’imiyoboro.
