He mīhini kei te whakamahi i ngā kōwhai aha hei whakatū whare, e hanga ana i te ihi o ētahi atu whare hei tautoko. E āhei ana ngā wāhi nei ki ngā whare, he pōhatu tuaka me ngā oneone huarahi. Ko ngā kōwhai aha matua galvanized steel I beams he nui te noho i raro i te whakamahere, nā te mea e whai ana i te tū tonu o tana mahi me te kawe i te kino o te momo (pango). Ko tēnei kauwaha o te hinuhinu he kaitangata whakapae mo te aha, e whakahoki ana i te pango me ētahi atu momo o te whakarereke. Ki te whakapakari i tēnei whakamārama, ka kitea te toru take ihe ko ngā take whakahirahira o ngā kōwhai aha matua galvanized steel hei tautoko whakatū. Tēnā pea ka tuku mai i a au ngā tākiri hinuhinu me te whakamāoritia i te mea ka noho pango, me te whakapae kia pai ki te whakamahi i waho, nā reira ka whai mana ai hei whakatū whare kāore i te whakapakari i to koutou koha, me pēhea ka whai mana ai hei matekura pai rawa, ka taea te whakamahi i ētahi atu whakahaere.
He nui ngā painga o te ehongsteel steel h beam ka whakamahi hei whakaatu rākau. Te pai mea o te kapa nui ko te mea ka taea e ia te tu tonu i roto i te pūtauaki, e whai wāhi ana ki te mōhiohio tonu me te tino hiranga i te whakanui i ngā mahi. E hanga ana ngā kīwai hei whakatiki i ngā mohiotanga nui, kia kore rawa i te tahuri, te maroke rānei, te taipū mai. Nā te mea hoki, kei te pai noa rātou ki te whakataki i te ahi. Kāore ngā kīwai aha o te toko iwi e āhei ana ki te whai ahi, ā, kāore hoki e āhei ana ki te whakaputu i te hū hiko kai i te wā o te ahi. I te wā o te āheinga, ka tono atu ngā manuhiri ki te haere ki te wāhi taihoa. Nā reira, kei te tino hiranga hoki ngā kīwai aha o te toko iwi, kei te tika hoki ki ngā momo hanga tuwhera katoa! Kei te pai ngā kīwai aha o te toko iwi mo te whakahaere i ngā tūranga, ahakoa he whakawehenga whare rānei, he whakawehenga ara motokā rānei, he pōhatu rānei.
He mea whakapuaki te galvanization ki te whakatakoto i te rima o te poraka ki runga i ngā rima o te kōpua hei kawe i te kōpua ki reira kia kaua e rūti (Wikipedia, 2018). Ko tēnei e hanga ai tētahi paenga whakamana ake hei tiaki i te kōpua i roto i te hāngai me te wai (e noho mau tonu) e hiahiatia ana hei hanga i te rūti. Ka mahi te poraka me te hā o te rangi ki te hanga i tētahi raraunga poraka ki runga i tana urupa. Tēnei ehongsteel h beam steel te rākau he tino pai te huarahi whakamau e kakeke ai te uruika i te miro, kāore i taea te whakatū mai i ana mata ki runga i tana mata. Nō reira, ngā pūtango ahi miro galvanised ka noho whakarite hoki i tetahi tohu waehere ā-waha i runga i te kaiwhakapuawaihanga zinc. Ka tāpiri anō tēnei kaiwhakapuawaihanga i tētahi rākau atawhai whakarite mo ngā tahuhu o ngā tahuhu e pa ana ki tō wāhitia, whakatūrangatia, rānei ko ngā whakamahi tonu o te ao kotahi.
He nui te mana o ngā pūtango I-ahimiro galvanised, ka taea e rātau te whakarite i ētahi o ngā momo hikoheke e pa ana i ngā taiao o waho me ngā whakahaere mahi. Kua hangaia hei whakatū tonu i ngā hikoheke e pā ana, pērā i te huka, te ua nui, te hau nui. Ko ia anō ka taea e rātau te whakarite i ngā momo raruraru ā-rewa; e hoko ana, ka kore ngā wai rerekē, pērā i ngā urenga rerekē rānei, e pāngia ki a rātau. Galvanized ehongsteel steel h-beam he pai tōna whakamahi mō ngā mahi hanga tuawhenua. Ki te kaiwhakamarumaru galvanize, ka hua ko ngā rākau i hanga i te mete galvanize hei rangi whaiaro mō ōu hanga e āhei ana ki te whakaatu i ngā tikanga kē, ā, me ēnei e hanga nei i roto i tētahi wharekura anake. Ko tēnei e mahi ana kia pūmau, ā, ka taea e rātau tonu te tautoko i waenganui i ngā whakaritenga kore pai.
Ki te whakatau ki ētahi atu rākau toko (Rākau Toko Kikokiko), ko te utu o te rākau galvanize ka noho iti rawa atu me te whai wāhi nui ake mō ngā hiahia whare whakatū. Ko ngā rākau toko kikokiko galvanize he mea iti utu anake, ā, ka noho tonu. He pūmau nui, ka taea e ia e noho whakatupu ana taua hekaheka me te kore e hiahia ana ki te whakahoki i ngā whakatika moni. Mēnā ka noho iti rawa ake te utu mō ngā rākau toko kikokiko i hanga i te kikokiko galvanize, ka whai take tonu i te wā e whakaora ana i a rātau, ka tiakina e rātau ngā moni nui mō ngā kaiwhakatū whenua. Nā tēnei whakapapa o te whai take iti me te pūmau nui, ko rātau he mea tino pai ki tētahi hanga.
Kei raro i te maha o ngā mahi nei ngā kaupapa e whakamahia ana e ngā hanga me ngā kaihanga whare ki ngā pūtango kōwhaiwairua i runga i ētahi atu rauropi, nō reira kaore i rokohanga, e mīharo ana ki tana nui ake tonu, e pai ai ki ngā hokihoki hei whakamahere i tana rangatiratanga. Ki te taea tērā, ka whakamahia e ia hei whakangungu i ngā kaupapa hanga nui, i ana pūtango nui e tautoko ana i ngā whare me ngā pōhatu hei whakarite i a rātou kia tirohanga. Ka whakamahia e rātou i waenga i ngā mahi hanga nui, mai i ngā oneone motuhake me ngā pōhatu ki ngā whare noho. I runga anō, kei te mutunga roa ngā pūtango kōwhaiwairua, he iti noa iho ngā whakatoke e hiahiatia ana i te hanga whenua. Ki te whakaarohia ngā āhuatanga nui o tēnei rauropi, ka mōhio haere ko te take i te pai ake o ngā utu pūtango kōwhaiwairua mō te nui o ngā kaupapa hanga.
Ka taea e mātau te tuku i ngā kīwai ā-haere i galvanize i runga i ngā paearu Ametika/Riponihia/Japani, ngā kīwai ā-haere H, me ngā rākau pikiwhara me te whakatupu i ngā ratonga paihikara, pērā i te pākiri me te tapa. Ka tukuna e mātau ngā mahi ki ngā whenua o te Uruiti, Oseania, Tai Hauāuru, Tai Rawhiti, Afirika, me te Māhea.
Te kāwanatanga o ngā pūtango āwhi tōru e 17 tau ana i te mahi i ngā whakahaerenga ā-motu mō ngā pūtango. Tēnā mātau ka taea te tautoko i te nui atu o ngā rīpoata me ngā paiaka. Ko ia anō hoki, kei tātau waka ake tonu ngā toa whenua motuhake, ko ngā whakarite ara moni ki reira, hei whakamana i ōu take me ngā whakaae pai. Mēnā ka nui ake ngā pouaru e tuku mai nei ki a mātau, ka iti ake te utu!
Ka tirotiroia ia ia kaihina i mua i te whakahoro. Ka whakapā te painga. Nō reira ngā kaihina matua he pūtango poroiti katoa (pūtango āwhi tōru, pūtango āwhi tōru ā-toru/SSAW/LSAW/ āwhi tōru/porowhita pipe/seamless pipe/pūtango porowhitu), paiaka (taumata Ametika, taumata Piritānia, taumata Aeternea H-pūtango), pūtango rākau, pūtango kona, pūtango whakarite, pūtango papa, pūtango o roto i ngā taurangi katoa me ngā rīpoata, pūtango whakarere, pūtango rīpoata, pūtango whakawhere, pūtango rīpoata, pūtango tā, ārā.
Kei a mātou ngā kaiwhakapuaki me te hunga tono tūmatawhānui i ngā kaupapa Galvanized steel beams, pūtake tohu āwhina me te ratonga matatika. He mea nui anō hoki te hunga pūkenginga tono mātau e taea ana i ngā wa 24 ki te whakautu i a koutou i ngā pātai, tono, whakaaetanga me ngā hiahia. Ke whakamana nei mātau i a mātau he hoa mahi whakapono mō koe.
