Ngā Pūrongo - Kurupae ASTM A36H vs. Kurupae H ASTM A992: Te Kōwhiri i te Kurupae H Tika mō te Whare Putunga Hanganga Rino

I te mea kei te piki haere ngā papa whakahaere taonga, ngā whare putunga hokohoko ipurangi, me ngā whare rokiroki ahumahi, kei te piki haere hoki te hiahia mō ngā whare H Steel Beam puta noa i te ao. I tēnei wā, e rua ngā rauemi e puta ake ana hei whakataurite i te nuinga o te wā ko teKurupae H ASTM A36me teASTM A992 H Kurupaehe mea noa ēnei e rua i roto ingā whare putunga hanganga maitai, mai i ngā anga māmā pērā i te kurupae W ki ngā pou taumaha whānui.

Papamuri Mākete

I te tau 2026, ka whānui haere te hanganga whare putunga i Amerika Te Raki, Āhia ki te Tonga-mā-rāwhiti, me Amerika Latina. Ka arotahi ngā kaiwhakawhanake ki:

1. Te tere ake o te whakatūnga mā te whakamahi i te tikanga paerewaKurupae Rino Āhua-Hngā pūnaha

2. Te kaha kawenga teitei ake me ngā rahi kurupae kua arotauhia

3. Te utu iti iho mō te huringa ora

Nā tēnei ia āhuatanga kua whakaaroaro rua te miihini i waenga i te A36 me te A992 ina tae mai ki ngā wāhanga noa pēnei i teKurupae W4x13, W8, W10, me ngā kurupae H taumaha.

ASTM A36 H Beam: Kōwhiringa Tuku Iho

Ko te ASTM A36 he maitai hanganga matarohia e whakamahia ana i roto i te maha o ngā tono kurupae maitai āhua-H.

Ngā Āhuatanga Matua:

1. Te kaha whakaputa iti rawa: 36 ksi (250 MPa)

2. He pai te mahi whakarewa me te mahi hanga

3. Utu iti iho mō ia tana

Tono Whare Putunga:

1. Ngā whare putunga iti, waenga rānei

2. Ngā anga māmā e whakamahi ana i ngā wāhanga pēnei iKurupae W4x13mō ngā kurupae tuarua

3. Ngā kaupapa e whakahaerehia ana e te tahua

Tirohanga Mākete:

Kei te whakamahia whānuitia tonu te A36 i ngā whenua whakawhanake, engari nā te iti o te kaha, ko te tikanga he nui ake ngā kurupae H, he nui ake rānei te rino e hiahiatia ana i ngā hoahoa hei whakatutuki i ngā kawenga hoahoa.

ASTM A992 H Beam: Paerewa Kaha-Teitei Hou

Kua hangaia motuhake a ASTM A992 mō te whānui-flange meKurupae Rino Āhua-Hngā hua.

Ngā Āhuatanga Matua:

1. Te kaha whakaputa iti rawa: 50 ksi (345 MPa)

2. He pai ake te ngāwari me te mahi rū whenua

3. Matū whakahaere mō te whakarewa māmā ake

Tono Whare Putunga:

Ngā pokapū whakahaere nui

Whare rokiroki teitei

Ngā anga hanganga rahi kua arotauhia pērā i ngā kōwhiringa māmā ake tae atu kiKurupae W4x13ina he āwangawanga te taumaha.

Tirohanga Mākete:

I te US me ētahi atu mākete whakawhanake, kua roa te A992 e whakamahia ana hei paerewa mō ngā kurupae W me H mō te hanga whare putunga.

Whakataurite Utu me te Mahi

Taonga	Kurupae H ASTM A36	ASTM A992 H Kurupae
Te Kaha o te Hua	36 ksi	50 ksi
Te Whakamahinga o te Rino	He nui ake te taumaha	He iti ake te taumaha
Ngā Wāhanga Noa	Kurupae H, kurupae W4x13 (mahi māmā)	Ngā kurupae H, kurupae W4x13 (hoahoa kua arotauhia)
Utu mō ia Wāhanga	I raro	Teitei ake
Te Utu Katoa o te Kaupapa	Kāore i te iti ake te utu i ngā wā katoa	He maha ake ngā wā he iti ake te ōhanga

Ahakoa he nui ake te utu mō ia tana o te A992, nā tōna kaha nui ka taea e ngā kaihangarau te whiriwhiri i ngā kōtaha kurupae maitai āhua-H iti ake, māmā ake rānei, ā, i ētahi wā ka hua ake he penapena 10–20% i te katoa o te maitai.
