Ko ngā kōtaha H-beam, e mōhiotia ana mō ō rātou momo tapahanga "H" motuhake, kua roa e mōhiotia ana mō ō rātou mahi miihini pai rawa atu. He rerekē kingā kōtaha maitai tuku ihopērā i ngā kurupae-I, he rite ngā parirau o runga me raro o ngā kurupae-H ki tētahi tukutuku matotoru, ā, ka taurite ake te tohatoha o te kaha. Mā tēnei painga hanganga ka taea e ngā kurupae-H te ātete atu ki te piko me te takahuri, ā, he mea pai rawa atu mō ngā wāhanga e mau ana i te kawenga i roto i ngā kaupapa piriti. Heoi, ko te whakaurunga o ngā mātāpono hoahoa mama te mea i huaki ai tōna pūmanawa katoa i ngā tau tata nei.

"Mō ngā tekau tau, i pāngia ngā kaihanga piriti e tētahi taupatupatu: hei whakanui ake i te kaha ki te pikau kawenga, he maha ngā wā i tika ai kia whakanuia te taumaha me te rahinga o te maitai i whakamahia, ā, i piki ake ai ngā utu hanga, i roa ake ai ngā wā kaupapa, ā, i tāpirihia ai te pēhanga ki ngā hanganga turanga," te whakamārama a Tākuta Elena Carter, he kaihanga hanganga matua i Global Infrastructure Innovations (GII), he kamupene matua i roto i te hoahoa me te hanga piriti. "Mā ngā kōtaha H-kurupae me te hoahoa mama, kua pakaruhia e mātou taua taupatupatu. Mā te arotau i ngā āhuatanga whakawhiti-wāhanga o ngā H-kurupae—te whakaiti i ngā rauemi kore e hiahiatia i ngā wāhi kore-tino nui, me te whakapakari i ngā rohe taumahatanga nui—kua hangaia e mātou ngā hanganga he mama ake engari he kaha ake ki te hapai i ngā kawenga taumaha."
