raungā whatu poraka
Nō ki te whakangāwangawa ā-taiao me te whakamahere hangarau, ko ngā rākau whakapiri aluminium he whakatau ake hou e whakaae ana i ngā pai tūmomo me te whanonga pūmau. E harakeke nei ngā rākau whakapiri aluminium i runga i ngā whakahaere tūpono, ka waihanga he uaua hoki, he noa iho tonu, ka puta he āhuatanga mōhio hoki. Hei tēnei, ko ngā rākau whakapiri o te kaiwhakawhanake tino pai, ka taea te whakauru ki roto i ētahi atu whakaaetanga, pērā i ngā rārangi, ngā kōwhiringa, rānei, hei whakamana i te whakaaro hangarau. Ko ngā rākau e taea ana te whakatika i ngā momo taiao, ahakoa te wā, ka mau tonu te rite ā-wheako. Ka noho ngā rākau i runga i ngā mahi powder coating rānei i te anodizing, ka whakamana i te rite kiritae me te whakahē i te koromiko. Ko tētahi atu āhuatanga matua o te whakawhanake, ko te hoahoa tuatahi, ka whakaae i te whakawhiti haere ki ngā raraunga o runga i te tahuhu, me te whakamahi tirohanga. Ka taea e ngā rākau whakapiri te whakauru i ngā rākau mīhini, ngā momo HVAC, me ētahi atu ratou hangarau whare. Ko ngā whakamahi o ngā rākau whakapiri aluminium e whai ana i ētahi atu whenua, nā te mea he nui ngā take whakamahere, pērā i ngā waehanga mahi pakirehua, ngā taiao porihina, ngā kura me ngā marae pūhaere. He whai mana hoki i ngā wā e hiahiatia ana ngā paerewa whakahaere, pērā i ngā whare hauora, nā te mea e taea ana te whakamahi i ngā kaiwhakatutuki me te whakahē i te wai me te koromiko.
