1) Nā kala like ʻole
He ʻeleʻele ka ʻili o ka pā i ʻōwili wela ʻia, a ʻokoʻa ke kala, a i ʻole he ʻano ʻaila ʻole ʻo bai.
2) Nā kihi ʻano like ʻole
He palupalu a laumania ke ʻano o ka pā i ʻōwili anu ʻia, a he maʻemaʻe ka lihi
He ʻāpiki ke ʻano o ka ʻili o ka papa i ʻōwili wela ʻia, ʻaʻole maʻamau ke ʻano no ka ʻōwili anu, a i kekahi manawa he ʻano ʻē nā kihi.
3) Nā kikoʻī like ʻole
ʻO nā papa i ʻōwili anu ʻia he lahilahi me ka mānoanoa o lalo o 3.0mm (koe wale nō no ka hoʻopilikino ʻana), ʻo ke keʻokeʻo kālā ka papa galvanized, a ʻo ke kala ka papa i uhi ʻia i ke kala.
ʻOi aku ka nui o nā papa i ʻōwili wela ma mua o 1.5mm (koe naʻe nā mea i hana ʻia), ʻaʻole emi ka lahilahi ma mua o 1.0, a he mau ʻano hoʻomakeʻa e pili ana i ka mahana.
4) Paʻakikī like ʻole
He paʻakikī ke hana ʻana i ka papa kila i ʻōwili anu ʻia a he paʻakikī ke hana, akā ʻaʻole maʻalahi ke hoʻololi a he ikaika kiʻekiʻe; He haʻahaʻa ka paʻakikī o ka papa kila i ʻōwili ʻia, maʻalahi ka hana ʻana a me ka ductility maikaʻi.
5) Nā kaʻina hana like ʻole
Hana ʻia ka ʻōwili anu i ka mahana maʻamau, ʻoi aku ka ikaika o ka papa kila i ʻōwili anu ʻia a he liʻiliʻi ka mānoanoa o ka ʻōwili anu; ʻOki ʻia ka papa kila i ʻōwili wela ʻia i ka mahana kiʻekiʻe, ʻoi aku ka maikaʻi o ka ductility, a hiki i ka papa kila i ʻōwili wela ʻia ke loaʻa ka mānoanoa nui.
