I roto i te umanga rino nui,koiri maitai wera-hurihiaHe rauemi tūāpapa tēnei, e whakamahia whānuitia ana i roto i ngā mara pēnei i te hanga, te hanga mīhini, me te umanga motuka. Ko te koiri maitai waro, me tōna mahi whānui pai me te whai huatanga utu, kua noho hei rauemi matua i te mākete. Ko te mārama ki ōna tawhā matua me ōna āhuatanga ehara i te mea he mea nui anake mō ngā whakatau hoko engari he mea nui hoki ki te whakanui ake i te uara o te rauemi.
Ka tīmata te hanga koiri maitai waro i tekoiri maitai warote wheketere, te wāhi e tukatukahia ai ngā pirepire hei koiri o ngā whakaritenga motuhake mā te tukanga hurihuri pāmahana teitei. Hei tauira,Koiri maitai ASTM A36He momo maitai e whakamahia whānuitia ana e ngā paerewa o te American Society for Testing and Materials (ASTM) ā, e tino hiahiatia ana i roto i ngā mara hanga me te hangarau hanganga. E whakamanamana ana te koiri ASTM A36 ki te kaha whakaputa o ≥250 MPa me te kaha kume o 400-550 MPa, me te ngāwari me te āheinga whakarewa pai rawa atu, e tutuki ai ngā whakaritenga kawenga me te hononga o ngā hanganga nui pēnei i ngā piriti me ngā anga wheketere. Ko tōna hanganga matū e pupuri ana i te ihirangi waro i raro i te 0.25%, e taurite ana i te kaha me te pakari me te karo i te pakarukaru e pā ana ki te ihirangi waro nui rawa atu.
Mai i te tirohanga tawhā, ko te matotoru, te whānui, me te taumaha o te koiri he tohu nui mō te aromatawai i te mahi a ngā koiri maitai hurihuri wera. Ko ngā matotoru noa kei waenga i te 1.2 ki te 25.4 mm, ko te whānui ka neke atu i te 2000 mm. Ka taea te whakarite i te taumaha o te koiri, mai i te 10 ki te 30 tana. Ko te whakahaere i ngā āhuatanga tika kāore e pā noa ki te pai o te tukatuka engari ka pā tika hoki ki te tika o te hua whakamutunga. Hei tauira, ko te manawanui matotoru o ngā koiri maitai hurihuri wera e whakamahia ana i roto i te hanga motuka me tino whakahaere i roto i te ±0.05 mm kia rite ai ngā āhuatanga o ngā wāhanga kua tāia.

He rerekē rawa ngā whakaritenga mahi mō ngā koiri maitai hurihuri wera i roto i ngā ahumahi. Ko te kaha me te ātete ki te huarere te mea nui ki te umanga hanga, ko te āheinga miihini ia te mea nui ki te miihini me te whakaotinga mata. Nō reira, me urutau e ngā kaihanga koiri maitai waro ā rātou tukanga whakaputa ki ngā hiahia o ngā kiritaki. Hei tauira, ka taea te whakamahi i ngā tikanga hurihuri me te whakamatao whakahaere hei whakapai ake i te hanganga o te witi, ka taea rānei te tāpiri i ngā huānga whakarewa hei whakarei ake i ngā āhuatanga motuhake. Hei tauira, mō ngā koiri e whakamahia ana i roto i ngā taiao haumākū teitei, mā te tāpiri i ngā huānga pēnei i te whākawa me te parahi ka taea te whakarei ake i te ātete ki te waikura o te hau.
Mai i te tukanga whakaputa a te kaihanga koiri maitai waro ki ngā whakaritenga tono a te kaiwhakamahi mutunga, ka honoa ngā tawhā matua me ngā āhuatanga o te koiri maitai hurihuri wera puta noa i te mekameka tuku. Ahakoa te hoko nui i ngā koiri maitai, te whiriwhiri rānei i ngā koiri ASTM A36 motuhake, he mea nui te māramatanga hohonu ki ngā āhuatanga o te rauemi hei whakatutuki i te taurite pai i waenga i te mahi me te utu, hei whakatakoto i te turanga pakari mō te whanaketanga kounga teitei puta noa i ngā momo ahumahi.
Kei roto i te tuhinga i runga ake nei ngā tawhā matua me ngā āhuatanga mahi o te koiri maitai hurihuri-wera. Mena kei te hiahia koe ki te kite i ngā whakarerekētanga, i ētahi atu taipitopito rānei, tena koa whakamōhio mai ki ahau.
