He mīhini anō nā Steel U beams hei whakamahere mō ngā kaupapa hanga me ngā kaupapa whawhangai e kitea ana e mātau i roto i ā mātau whenua. Kua hangaia rātou i te toto, he materahea tika mō te maia. Nā reira, e āhei ana ēnei pū kia takohia te nui o ngā mana e kore ai e whakawhitinga, e kore ai e whati. E āheitia ana ngā U Beams o te toto i waenganui i te nui o ngā momo me ngā āhua, engari ko te mea nā te whei ao nei te take i aua ingoa. He āhua u anō hoki, e āwhina ana ki te whakapāngia mai i te mana i runga i te wāhi, me te hokinga whakamua i te nui o ngā mea. Nā tēnā mea ka kitea e koutou ngā U beams i waenganui i ngā wāhi.
He nui te mana āhuarangi me te whakatika o ngā kōrari U aho toko. Ko te aho toko he mea nui rawa te mana, ka hāngai tētahi māramatanga pai o te kawe, engari kāore e pūmau ki te taumanu rite ki te take nui. He pai te aho toko ki te whakamahia mo te hanga i ngā mea e hiahiatia ana te whakaū. E kitea ana ngā wharekura U aho toko i roto i ngā wāhi katoa -- mai i ngā pōhutukawa ki ngā whare rangi matangaro, ā, hoki hāpai hoki i waenganui i ngā rua whenua. Ko tēnā whanaketanga e mahi ai i a rātou he matera whakahaere i te hanga, ina e hiahia ana ngā hanga ki te hanga i ngā whare me ngā tuara kaha me te haumaru.
He mea nui te whakaū i ia whare rānei, i ia tuara rānei. Ka hinga ngā whare, ka noho kore haumaru ngā tangata ki te kore e taea ana te whakapuaki i te mīharo. Mahi nei ngā kōrari U aho toko i te whakamahere i tēnei whakaū, nā te mea ka whakaae atu rātou ki te kawe i ngā take nui katoa kāore i te kuhu i te kawe. He mea nui hoki te whakatika, ka taea e rātou e mahi ana i ngā huringa hau me te ua nui, ā, hoki hāpai hoki i ngā hau 150 mph (240 km/h) rānei, ki te mate whenua hoki. Nā tēnei whakauru, ko rātou he pai tonu mo ngā wāhi e hiahiatia ana ngā harakeke rānei, ā, ngā huinga tahora o te ao.
Nō te whakamahi i ngā kākano U ahu arai, he nui ngā pai me ngā hua. Ki te tīmata, he whēako rātou, ā, e āhei ana ki te whakaaro i ngā huamahi nui i waenganui i ngā āhuatanga huarere rerekē. Ko te tuhi whatunga o ēnei he nui rawa atu ngā momo, ka tukua mai ngā momo home rerekē. Ko tēnei ka whakaae ki ngā hangaia, kia whakamahia e rātau i ngā pūtoko, ngā kura, ngā whare... me ngā whare roa. He mōhio hoki rātou ki te whakauru me te whakapau haere, ka tiakina te wā i te whakawhitiwhiti. E ai ki ētahi, ka taea te whakatika hei whakatutuki i te mahi, ka whakaritea ki te mea e pai ake. Tērā pea, ka whakaiti hoki ngā utu hanga mō ngā hangaia, ka hiki noa iho he pai tēnei.
Nui atu ngā pūtango U whero i te hanga i ngā whare hou me ngā whakatū o nāianei. Ko ēnei ngā wāhanga e taea ana te kawe i ngā mohiotanga, ka awhina ki te whakapakari i ngā whare roa rawa (pērā i ngā wharetōpū), ngā paepae roa, me ēnei tuara nui hoki kia whai kaha kia kaua e kore nei. Kua kitea mai ko te pūtango U whero hei mea nui, kua whai mana hoki i te rautaki hanga mō tana tirohanga whakaaro mō te whakarite, te kaha, me te pai hoki i runga i te whakatū. Ka kite i a koe i ngā take hanga nui, pērā i ngā wharetōpū, ngā paepae me ngā whakamaharatanga nui o era. Ko ngā pūtango I me ngā pūtango U whero ko ngā iwi matua o te hanga i te ao o nāianei.
Ka taea e mātau te tuku i ngā kauwhimanga H-aka Ametika/Ripene/Japani me ngā pūnaha aka tawhiti me te whakatupu i ngā mahi whakarerekē pūnaha, pērā i te koukou me te tapa. Ka tukuna ake ngā mahi o mātau ki West Europe, Oceania, South America, Southeast Asia, Africa, Middle East rānui.
Kei a mātau tētahi kīwai whai take tino paunga i te mōhiohio me te tautoko tino pai i ngā kauwhimanga aka. Kei a mātau ngā kaimahi tukutahi ka whai wā ka whakahoki i ngā pātai rānei, ngā mōhiohio rānei e pā ana ki a koe. Kei te haere tonu mātau ki te whakaaetanga he kaiwhakatutuki tōmua ki a koe.
