ʻO nā mea metala i hoʻohana pinepine ʻia i nā ʻāpana lako a mākou e hoʻohana pinepine ai, ʻo ia ke kila kila, ke keleawe, ka alumini, ka zinc alloy, ka magnesium alloy, ke kila, ka hao, a pēlā aku.
Wahi a nā ʻano hana like ʻole, ua māhele pinepine ʻia nā huahana lako i ka hana anu a me ka hana wela, a he ʻokoʻa hoʻi nā ʻano hana hana metala like ʻole. ʻO nā mea hana anu e like me ka pepa metala e hana nui ʻia e ka hehi anu make, ke kūlou ʻana, ke kahakiʻi hohonu a me nā kaʻina hana ʻē aʻe. ʻO nā ʻāpana hana wela, e like me nā ʻāpana hoʻolei, hana nui ʻia ma ka hoʻoheheʻe ʻana i nā mea maka lako i loko o ka wai a me ka hoʻolei ʻana me nā ʻōmole.
Manaʻo nui ʻia ʻo nā mea pepa metala āpau me ka mānoanoa like ua kapa ʻia he pepa metala. ʻO nā mea pepa metala i hoʻohana pinepine ʻia e komo pū me ke kila kila, ka papa kila galvanized, ka tinplate, ke keleawe, ka alumini, ka hao, a pēlā aku.
❶ kumumanaʻo o ka mānoanoa like o ka huahana
He mea like ka mānoanoa o ka pepa metala, pono e makaʻala ʻia i ka hoʻolālā kūkulu ʻana, ʻoiai ma kahi he nui nā kūlou, he maʻalahi ke hana i ka mānoanoa like ʻole.
❷ ke kumumanaʻo o ka hoʻopālahalaha maʻalahi
Hana ʻia nā huahana pepa metala mai nā pepa. Ma mua o ka hana ʻana, ua pālahalaha nā mea maka. No laila, i ka hoʻolālā ʻana i nā ʻāpana pepa metala, pono e hiki i nā kūlou a me nā mokulele hilig ke wehe ma ka mokulele like me ke keakea ʻole. No ka laʻana, ʻaʻole kūpono ka hoʻolālā ʻana o nā ʻāpana pepa metala i hōʻike ʻia ma ke Kiʻi 1-1 no ka mea ke hoʻopilikia nei lākou kekahi i kekahi ma hope o ka wehe ʻana.
❸ ke kumumanaʻo o ke koho pono ʻana i ka mānoanoa o nā ʻāpana metala pepa
ʻOkoʻa ka mānoanoa o nā ʻāpana pepa metala mai 0.03 a i 4.00mm, akā ʻo ka nui o ka mānoanoa, ʻoi aku ka paʻakikī o ka hana ʻana, ʻoi aku ka nui o ka pono no nā lako hana, a piʻi ka nui o nā hemahema. Pono e koho ʻia ka mānoanoa e like me ka hana maoli o ka huahana. Ma ke kumu o ka hoʻokō ʻana i ka ikaika a me ka hana, ʻoi aku ka maikaʻi o ka lahilahi. No ka hapa nui o nā huahana, pono e kāohi ʻia ka mānoanoa o nā ʻāpana pepa metala ma lalo o 1.00mm.
❹ kūlike i ke kumumanaʻo o ka ʻenehana hana
Pono nā huahana pepa metala e kūlike me ka ʻenehana hana a maʻalahi hoʻi e hana. ʻAʻole hiki ke hana ʻia nā huahana i kūlike ʻole me ka ʻenehana hana, ʻo ia hoʻi, he hoʻolālā kūpono ʻole.
