1. Kakaretso ea Sehlahisoa le Litšobotsi tsa Tekheniki
S355J2H ke sehlopha sa tšepe sa sebopeho se hlalositsoeng tlas'a maemo a Europe EN 10219 (likarolo tse se nang letho tsa sebopeho tse entsoeng ka serame) le EN 10210 (likarolo tse se nang letho tsa sebopeho tse phethiloeng ka ho chesa), tse sebelisoang haholo makaleng a kaho ea likepe, boenjiniere ba leoatleng, kaho le mechini e boima. Litšobotsi tsa bohlokoa li kenyelletsa:
Kereiti ea Matla: S355 e bontša matla a bonyane a tlhahiso ea 355 MPa (bakeng sa botenya ba lebota≤16mm), ka matla a ho thapolla a tlohang ho 470 ho isa ho 630 MPa
Ho Tiea ha Mocheso o Tlase: J2 e emela matla a tshusumetso a Charpy≥27J ho -20°C, ho fihlela litlhoko tsa tšebeletso bakeng sa likepe tse sebetsang maemong a Europe Leboea le a leoatle le batang

Kahong ea likepe, lipeipi tse sekwere tsa S355J2H li sebelisoa haholo-holo bakeng sa meralo ea khetla, litšehetso tsa bulkhead, likarolo tsa sebopeho se seholo, likarolo tsa liaparo, le li-module tsa sethala sa leoatleng.
2. Kakaretso ea Kopo ea 'Maraka oa Europe
Liindasteri tsa kaho ea likepe tsa Europe le tsa boenjiniere ba leoatleng li boloka tlhoko e tsitsitseng ea lipeipi tsa tšepe tsa meaho tse matla haholo. Lipeipi tsa lisekoere tsa S355J2H li fetohile khetho e kholo ea thepa makaleng a likepe tsa Europe le a leoatleng ka lebaka la karolelano ea tsona e ntle ea matla ho ea boima le ho tiea ha mocheso o tlase.
Libaka tsa bohlokoa tsa ts'ebeliso li kenyelletsa:
Likepe tsa Khoebo: Likarolo tsa sebopeho sa Hull bakeng sa likepe tsa lik'hontheinara, lijari tse kholo le likepe tsa litanka
Lisebelisoa tsa kantle ho naha: Meaho ea tšehetso bakeng sa liforomo tsa ho kenya moea tsa kantle ho naha le liforomo tsa ho cheka
Likepe tse Ikhethileng: Likepe tse pshatlang leqhoa, likepe tsa lipatlisiso tsa polar, le mefuta e meng ea likepe tse hlokang ho tiea ha mocheso o tlase haholo
Litšebeletso tsa Kou le Likepe: Meaho ea likepe tse omileng le lisebelisoa tsa ho phahamisa tse ka thoko ho kou
Jeremane, Belgium, Netherlands le Italy ke tsona tse rekang thepa ka bongata Europe ka ntle ho naha di-tube tsa sekwere tsa S355J2H. Dikou tsa Antwerp (Belgium) le Rotterdam (Netherlands) di sebetsa e le ditsi tse kgolo tsa kabo ya tshepe tsa Europe, tse sebetsanang le bongata bo boholo ba phetiso ya thepa.
3. Tlhahlobo ea Bongata ba Lintho Tse Kenoang ka Hare
Ho ya ka dikhakanyo tsa data ya kgwebo ya indasteri, thepa ya selemo le selemo ya China ya di-square tube tsa S355J2H e romelwang kantle ho naha mmarakeng wa Yuropa e ntse e le pakeng tsa ditone tse ka bang 170,000 ho isa ho 220,000 nakong ya 2022-2023. Dihlahiswa tsa China di bolokile karolo e hlahelletseng ya mmaraka Europe ka lebaka la boleng bo tsitsitseng le tlholisano ya ditheko. Ho sa tsotellehe mesebetsi ya EU ya ho thibela ho lahla dihlahiswa tse itseng tsa tshepe tsa China, phepelo ya China e ntse e le ya bohlokwa karolong ya dikarolo tse se nang letho tsa meaho.
4. Mefuta e Tloaelehileng ea Litlhaloso tsa ho Reka ka Hare
'Maraka oa Europe hangata o kenya lipeipi tsa lisekoere tsa S355J2H ka har'a mefuta e latelang ea litlhaloso:
