Ezimbonini zokwakha nezobunjiniyela, amazinga adlala indima ebalulekile ekuqinisekiseni ukuphepha, ukwethembeka kanye nekhwalithi. Elinye izinga elaziwa kabanzi e-Europe yi-EN 10219, elimboza izingxenye zesakhiwo ezishiselwe ezishiselwe. Phakathi kwamabanga ahlukahlukene ashiwo kuleli zinga, i-S235JRH iphawuleka ngokukhethekile. Kule bhulogi, sizobhekisisa ukuthi yiniI-EN 10219 S235JRHizindlela, ukusetshenziswa kwayo, nokubaluleka kwayo emisebenzini yokwakha yesimanje.
I-EN 10219 iyindinganiso yaseYurophu echaza izimo zokulethwa kwezobuchwepheshe zezingxenye ezingenalutho zesakhiwo esakhiwe ngokubandayo. Lezi zingxenye zingaba yindilinga, isikwele noma unxande futhi zakheke ngokubanda ngaphandle kokwelashwa kokushisa okulandelayo. Lokhu kusho ukuthi impahla igcina izakhiwo zayo zangempela, iyenze ifaneleke uhla olubanzi lwezinhlelo zokusebenza zesakhiwo. Izinga liqinisekisa ukuthi lezi zingxenye ezingenalutho zihlangabezana nezidingo ezithile mayelana nezakhiwo zemishini, ukwakheka kwamakhemikhali nokubekezelela kobukhulu.
I-S235JRH ibhekisela ebangeni elithile lensimbi elithobelana nezinga le-EN 10219. I-"S" ikhombisa ukuthi iyinsimbi yesakhiwo futhi "235" ikhombisa ukuthi impahla inamandla amancane okukhiqiza angama-235 megapascals (MPa). I-"J" ikhombisa ukuthi insimbi ifaneleka ukushisela futhi i-"RH" ikhombisa ukuthi iyisigaba esingenalutho. Le nhlanganisela yezakhiwo yenza i-S235JRH ibe inketho efanelekile yohlu olubanzi lwezinhlelo zokusebenza zesakhiwo.
Enye yezinzuzo eziyinhloko zokusebenzisa izingxenye ezingenalutho ze-S235JRH isilinganiso sayo samandla nesisindo. Inqubo yokubumba ebandayo ingakha izakhiwo ezingasindi kodwa eziqinile, zehlise kakhulu isisindo sesakhiwo noma iphrojekthi yengqalasizinda. Lokhu kuzuzisa ngokukhethekile ekusetshenzisweni lapho isisindo siyinto ebalulekile, njengamabhuloho, imibhoshongo nezakhiwo eziphakeme.
Ukwengeza, ukuguquguquka kwezigaba ezingenalutho ze-S235JRH kuzenza zilungele uhla olubanzi lwezinhlelo zokusebenza. Zingasetshenziswa ekwakhiweni kwamafreyimu, amakholomu kanye nemishayo, kanye nokwakhiwa kwefenisha nezinye izingxenye zesakhiwo. Amandla okushiselwa ndawonye kalula akhulisa ukuguquguquka kwedizayini, okuvumela onjiniyela nabadwebi bezakhiwo ukuthi bakhe izakhiwo eziqanjiwe nezijabulisa ngobuhle.
Esinye isici esibalulekile se-EN 10219 S235JRH ukuhambisana kwayo nezindinganiso zokuphepha nekhwalithi zase-Europe. Ngokunamathela kuleli zinga, abakhiqizi bangaqinisekisa ukuthi imikhiqizo yabo ihlangabezana nezidingo ezidingekayo zobuqotho besakhiwo nokusebenza. Lokhu akugcini nje ukuthuthukisa ukuphepha kwesakhiwo sokugcina, kodwa futhi kwandisa ukuzethemba kwamakhasimende nabathintekayo ngekhwalithi yezinto ezisetshenziswayo.
Kafushane, i-EN 10219 S235JRH iyindinganiso ebalulekile emkhakheni wezokwakha nobunjiniyela, enikeza isiqondiso sokusebenzisakubanda kwakheka ashiselwe kwesakhiwoizingxenye ezingenalutho. Inhlanganisela yayo yamandla, ukwenza izinto ezihlukahlukene kanye nokuhambisana nezindinganiso zokuphepha kuyenza ibe ukukhetha okuhle kakhulu kwezinhlelo zokusebenza eziningi. Njengoba imboni yezokwakha iqhubeka nokuthuthuka, ukubaluleka kokuhambisana nalezi zindinganiso kuzokhula kuphela, kuqinisekiswe ukuthi izakhiwo zokwakha zihlala isikhathi eside kuyilapho kugcinwa ukuphepha kanye nekhwalithi. Noma ngabe ungunjiniyela, umakhi noma usonkontileka, ukuqonda nokusebenzisa i-EN 10219 S235JRH kungakhuphula kakhulu impumelelo yephrojekthi yakho.
