S355 steel ke boemo ba tšepe ba Europe bo tloaelehileng, ho latela EN 10025-2: 2004, thepa S355 e arotsoe ka limaraka tse 4 tsa boleng bo holimo:
Mehaho ea tšepe ea sebopeho S355 e betere ho feta tšepe S235 le S275 ka matla a ho kotula le ho tiea.
Litlhaku le linomoro tse latelang li hlalosa moelelo oa tšepe oa S355.
Ka tlase ho na le litafole tse bontšang database ea tšepe ea S355 e kenyeletsang metsoako ea lik'hemik'hale, matla a tlhahiso, matla a tsitsitseng le bolelele, joalo-joalo. Leqephe lohle la lintlha la DIN EN 10025-2 le tšoana le BS EN 10025-2 le linaha tse ling tsa litho tsa EU.
Lethathamo le ka tlase le bonts'a sebopeho sa lik'hemik'hale tsa tšepe tsa sehlopha sa S355.
