1. Rauemi o ngā ringaringa ararewa
Ngā pūmau ararewahe mea hanga i te rapa kounga teitei, i te PVC rānei. I roto i ēnei, he pai te ātete o ngā ringaringa rapa ki te kakahu me te waikura, ā, he ngāwari ki te horoi me te tiaki; ko ngā ringaringa PVC ia he ātete ki te pāmahana teitei me te ātete ki te tawhito, ā, he ngāwari ake te horoi me te tiaki.
2. Ngā Whakatakotoranga o ngā Pupuri Ararewa
Ko ngā whakaritenga o ngā ringaringa arawhata e whakawhirinaki ana ki te roa me te whānui o ngā ringaringa. I te nuinga o te wā, ko te roa o te ringaringa he rite ki te roa o te arawhata, arā, ko te roa o te ringaringa he 800mm, he 1000mm rānei; ko te whānui ia o te ringaringa he 600mm, he 800mm rānei.
3. Tikanga tāutanga o ngā ringaringa ara piki
Ko te tāutanga o ngā ringaringa arawhata e wehea ana kia rua ngā tikanga, arā, te momo piri tika me te momo whakairi whāriki. He ngāwari te tāutanga o te momo piri tika, engari me whai mata pakitara maroke, papatahi; ko te momo whakairi whāriki me whai whāriki hei whakapiri i te whāriki, engari ka taea te urutau ki ngā rauemi pakitara me ngā whāriki rerekē.
4. Ngā Pātai Auau mō ngā Puringa Ara Whakatere
Kia pēhea te tawhiti e toe ana i waenganui i te kakau me te anga o te kakau?
（1）Whakautu: Me whai āputa 1mm ki te 2mm i waenganui i te whitiki pupuri me te anga pupuri kia kore ai e pakaru, e haruru rānei i te wā e whakamahia ana.
（2） Kia pēhea te auau o te whakakapinga o ngā ringaringa?
Whakautu: Ko te roa o te wā whakakapinga o ngā ringaringa e whakawhirinaki ana ki te auau o te whakamahinga me te taiao. Ko te tikanga kia whakakapia kotahi i te tau.
（3）He ngāwari te whakapēhea, te taka rānei o ngā kakau, me aha ahau?
