Ko te ārai-taka houwhakapiriHe hototahi ki te diameter paipa paerewa o te 48.3mm, e mau tonu ana i ngā āhuatanga tāutanga tere o ngā whakapiri tuku iho, me te whakatutuki i te huringa ngāwari i waenga i te koki matau, te hurihanga, me ngā mahi taunga mā te hoahoa modular. Kua piki ake te whai huatanga o te tāutanga mā te 40% ki te whakataurite ki mua i te whakamahinga o te hangarau patent. I roto i tētahi papa ahumahi matū i te raki-mā-rāwhiti o Haina me te pāmahana iti me te haumākū teitei, ka eke tonu te pakari pānga o te hua i te -30 ℃ ki te 95J. I te whakakotahitanga me te maimoatanga ārai waikura takirua me te whakapūmau, ka heke te tere waikura mā te 90% ki te whakataurite ki te mea noa.ngā whakapiriā, ka roa ake te ora ratonga ki te 12 tau.

I runga i te āheinga o te hangarau BIM ki te urutau i mua i te huihuinga, ko tēneiwhakapiriKa tutuki te hononga tika me te hapa o te ≤ 0.1mm i roto i te hanganga kua oti te hanga, ka whakaitihia te wā hanga tūāpapa mā te 15%. I tēnei wā, kua whakamahia ki ngā kaupapa nui e 12 pērā i te whakawhānui ake i te Pokapū Huihuinga me te Whakaaturanga o te Ao o Shanghai, te whakakapi i te neke atu i te 800,000 huinga o ngā whakapiri tuku iho, me te whakaiti i te auau aituā haumaru mā te 78%. Kua noho hei taputapu matua mō ngā umanga hanga hei whakatinana i ngā whakaritenga o te "Marama Whakaputa Haumaru".
