Te Rino H-Kurupae i roto i te Hanganga Hanganga: He aha te Tino Hiahiatia ai te Rino H-Wāhanga ASTM A992 me te S355

Ko te H Beam Steel tonu te whiringa pai rawa atu mō te wāhanga mākete o te maitai hanganga ināianei kei te piki haere te haumitanga hanganga o te ao i Amerika Te Raki, Āhia ki te Tonga-mā-rāwhiti me Amerika Latina. Mai i ngā pokapū tohatoha nui ki ngā whare tari teitei, kei te tahuri ngā kaimahi kirimana ki te H Section Steel ASTM A992 me te EN S355 mō tōna kaha teitei, tōna pono, me tōna whai huatanga utu.

Te Tūranga Tipu Ake o te H Beam Steel i roto i te Hanganga Hou

Ko ngā kurupae H—e mōhiotia ana ko te maitai wāhanga H, ko ngā kurupae whānui rānei—e whakamahia whānuitia ana i roto i:

  • Ngā whare hanganga maitai ahumahi

  • Ngā whare putunga kua oti te hanga

  • Ngā whare hokohoko

  • Ngā kaupapa pūngao me ngā hanganga

  • Ngā papa piriti me ngā papa taumaha

Mā te wāhanga whakawhiti ōrite e whakaratotohatoha kawenga tino pai, he mea tino pai mō ngā pou poutū, ngā kurupae, me ngā anga tautoko matua.

He aha te take e tino hiahiatia ai te ASTM A992

Kua noho ko ASTM A992 te rauemi paerewa mō te maitai hanganga i Amerika Te Raki nā:

Te kaha whakaputa iti rawa o te 345 MPa (50 ksi)
He tino pai te whakarewa me te ngāwari
Te whakahaere hanganga matū ōrite
He mahi tino pai i roto i ngā rohe ru whenua

Ki te whakatauritea ki te ASTM A36 tuku iho, he kaha ake te A992 me te pono o te hanganga, ā, he iti ake te whakamahinga o te maitai i roto i ngā kaupapa nunui.

He aha i rongonui ai te maitai wāhanga H EN 10025 S355 puta noa i te ao

E whakamahia whānuitia ana ngā kurupae H S355 i Ūropi, te Waenganui Rawhiti, me ngā mākete kaweake nā ēnei mea:

Te kaha whakaputa teitei (≥355 MPa)
Te ātete kaha ki te ngenge
He tino pai te mahi i roto i ngā hanganga taumaha
Te tutuki i ngā ture hangahanga o Ūropi

He tino pai te maitai hanganga S355 mō ngā whare ahumahi, ngā whare putunga ratonga, me ngā kaupapa hanganga e hiahia ana kia nui te kaha ki te pikau kawenga.

Ngā Auahatanga o te Mākete e Ārahi Ana i te Hiahia Nui

  1. Te Tere o te Noho Tāone– Ko te whānui haere o ngā rohe ahumahi ka nui ake te hiahia mō ngā whare anga rino.

  2. Te tipu o te hanga maitai kua oti te hanga– He tere ake te tāutanga me te whakaiti i ngā utu mahi.

  3. Ngā Whakaritenga Haumaru mō te Rūwhenua– Ko ngā momo kaha ake pērā i te A992 me te S355 e tutuki ana i ngā ture hanga whare tino pakari.

  4. Hanganga Tauwhiro– Ka taea te hangarua 100% te maitai, ā, e tautoko ana i ngā kaupapa hanga whare matomato.

I te mea kei te haumi tonu ngā kāwanatanga ki ngā mahi kawe waka, ki te rokiroki pūngao, me ngā whare hanga, kei te piki haere tonu te hiahia mō te maitai kurupae H-teitei.

Whakamutunga

Ko te pikinga ake o te hiahia mō te maitai wāhanga H ASTM A992 me te S355 he wāhanga noa iho o te ia whānui hei whakatutuki i te hiahia mō ngā otinga hanganga kaha ake, haumaru ake, engari he iti ake te utu. I te mea e huri haere ana ngā paerewa hanga puta noa i te ao, kei te noho tonu te maitai kurupae H kounga hei rauemi pou mō ngā kaupapa hanganga me ngā kaupapa ahumahi o te ao.
