Ngā momopuranga pepa maitai
E ai ki "Puranga Rau Rino Hurihia Wera"(GB/T 20933-2014), e toru ngā momo o te puranga rino hurihuri wera, ko ngā momo motuhake me ō rātou ingoa waehere e whai ake nei:Puranga rino momo-U, ingoa waehere: puranga pepa maitai momo PUZ, ingoa waehere: puranga pepa maitai raina PZ, ingoa waehere: PI Kia mōhio: ko P te reta tuatahi o te puranga pepa maitai i te reo Ingarihi (Puranga), ā, ko U, Z, me I e tohu ana i te āhua whakawhiti-wāhanga o te puranga pepa maitai.
Hei tauira, ko te puranga rino momo-U e whakamahia whānuitia ana, ko te PU-400X170X15.5, ka taea te mārama he 400mm te whānui, 170mm te teitei, 15.5mm te matotoru.

Puranga rino momo-U
He aha i kore ai e whakamahia whānuitia te momo-Z, te momo-tika rānei, engari ko te momo-U i roto i te hangarau? Inaa, he rite tonu ngā āhuatanga ā-pūkaha o te momo-U me te momo-Z mō te puranga kotahi, engari ko te painga o te puranga rino momo-U e kitea ana i roto i te mahi tahi o ngā puranga rino momo-U maha.
Mai i te pikitia i runga ake nei, ka kitea ko te pakari piko mō ia mita rārangi o te puranga pepa maitai momo-U he nui ake i tērā o te puranga pepa maitai momo-U kotahi (ka nekehia te tūranga o te tuaka kūpapa) i muri i te ngau tahi i te puranga pepa maitai momo-U.
2. Rauemi puranga rino
Kua whakakorehia te kounga maitai Q345! E ai ki te paerewa hou "Low Alloy High Strength Structural Steel" GB/T 1591-2018, mai i te 1 o Pēpuere, 2019, kua whakakorehia te kounga maitai Q345 ka hurihia ki Q355, e rite ana ki te paerewa maitai S355 a te EU. Ko te Q355 he maitai kaha-teitei noa, he iti-koranu, he kaha tuku o te 355MPa.
