Mō ngā umanga hanga me te miihini, he mea nui ngā paerewa hei whakarite i te haumaru, te pono me te kounga. Ko tētahi paerewa e mōhiotia whānuitia ana i Ūropi ko te EN 10219, e kapi ana i ngā wāhanga hanganga kōhao i whakarewahia i te makariri. I roto i ngā momo taumata kua tohua i roto i tēnei paerewa, ko te S235JRH te mea tino hira. I roto i tēnei tuhinga, ka tirohia e tātou he ahaEN 10219 S235JRHte tikanga, ōna tono, me tōna hiranga ki ngā kaupapa hanga o ēnei rā.
Ko te EN 10219 he paerewa Pākehā e whakamārama ana i ngā tikanga tuku hangarau mō ngā wāhanga hanganga tuwhera kua whakarewahia i te makariri. Ka taea e ēnei wāhanga te porowhita, te tapawhā, te tapawhā rānei, ā, ka hangaia i te makariri me te kore he maimoatanga wera i muri mai. Ko te tikanga o tēnei ka mau tonu ngā āhuatanga taketake o te rauemi, ā, he pai mō te whānuitanga o ngā tono hanganga. Mā te paerewa ka whakarite kia tutuki i ēnei wāhanga tuwhera ngā whakaritenga motuhake e pā ana ki ngā āhuatanga miihini, te hanganga matū me ngā manawanui ā-ahu.
Ko te S235JRH e pā ana ki tētahi momo maitai motuhake e tutuki ana i te paerewa EN 10219. Ko te "S" e tohu ana he maitai hanganga, ā, ko te "235" e tohu ana ko te kaha whakaputa iti rawa o te rauemi he 235 megapascals (MPa). Ko te "J" e tohu ana he pai te maitai mō te whakarewa, ā, ko te "RH" e tohu ana he wāhanga tuwhera. Nā tēnei huinga o ngā āhuatanga ka waiho a S235JRH hei whiringa pai mō te whānuitanga o ngā tono hanganga.
Ko tētahi o ngā painga matua o te whakamahi i ngā wāhanga kōhao S235JRH ko tōna ōwehenga kaha-ki-taumaha. Ka taea e te tukanga hanga matao te hanga i ngā hanganga māmā engari kaha, ka whakaiti nui i te taumaha katoa o tētahi whare, o tētahi kaupapa hanganga rānei. He tino whai hua tēnei i roto i ngā tono e whai pānga nui ana te taumaha, pērā i ngā piriti, ngā pourewa me ngā whare teitei.
Hei tāpiritanga, nā te maha o ngā whakamahinga o ngā wāhanga tuwhera o te S235JRH, he pai mō ngā momo mahi maha. Ka taea te whakamahi i roto i te hanganga o ngā anga, ngā pou me ngā kurupae, tae atu ki te hanga taonga me ētahi atu wāhanga hanganga. Mā te ngāwari o te honohono ka nui ake te ngāwari o te hoahoa, ka taea ai e ngā kaihanga me ngā kaihoahoa te hanga i ngā hanganga auaha me te ātaahua.
Ko tētahi atu āhuatanga nui o te EN 10219 S235JRH ko tōna tutuki i ngā paerewa haumaru me te kounga o Ūropi. Mā te piri ki tēnei paerewa, ka taea e ngā kaihanga te whakarite kia tutuki i ā rātou hua ngā whakaritenga e tika ana mō te pono o te hanganga me te mahi. Ehara i te mea ka whakapai ake i te haumaru o te hanganga whakamutunga anake, engari ka whakapiki ake hoki i te whakapono o ngā kiritaki me ngā kaipupuri hea ki te kounga o ngā rauemi e whakamahia ana.
Hei whakarāpopototanga, he paerewa nui te EN 10219 S235JRH i roto i te rāngai hanga me te miihini, e whakarato ana i ngā aratohu mō te whakamahinga ohanganga whakarewa mataongā wāhanga takoto kau. Nā te whakakotahitanga o te kaha, te whānui o te whakamahinga, me te tutuki i ngā paerewa haumaru, he mea pai rawa atu tēnei mō te whānuitanga o ngā mahi. I te whanaketanga tonu o te umanga hanga, ka piki ake te hiranga o te tutuki i aua paerewa, kia mau tonu ai te pakari o ngā hanganga whare, me te pupuri tonu i te haumaru me te kounga. Ahakoa he miihini koe, he kaihoahoa, he kaimahi kirimana rānei, mā te mārama me te whakamahi i te EN 10219 S235JRH ka nui ake te angitu o tō kaupapa.
