Ko ngā pōro whāriki he porowhita e whakamahia ana i roto i ngā whāriki hurihuri hei whakaiti i te waku i waenga i ngā wāhanga neke, he mea hanga i te nuinga o te wā mai i te maitai pakari, te uku, te kirihou rānei. Ko ngā rauemi matua ko te maitai kōroma SAE 52100 mō te whakamahinga whānui, te maitai kore waikura 440C mō te ātete ki te waikura, me te silicon nitride mō ngā tono tere-teitei/ranu. Ka whakaratohia ngā pōro whāriki katoa me ngā pōro kau.
