Hoʻohana nui ʻia ka mīkini wiliwili uila i ka ʻoihana, ka mahiʻai, ke kūkulu ʻana, ka lawe ʻana, ka mining a me nā ʻoihana ʻē aʻe.E like me ka uhi pale mīkini, ka pā holoholona, ka pā pua, ka pā pukaaniani, ka pā kahawai, ka hīnaʻi moa, ka hīnaʻi hua manu a me ka hīnaʻi ʻai hale keʻena, ka hīnaʻi pepa a me nā mea hoʻonani.Hoʻohana nui ʻia ia no ka pā hale ma waho o ka pā, ka ninini ʻana i ke kaʻa, nā hale noho kiʻekiʻe, a me nā mea ʻē aʻe, e pāʻani ana i ka hana koʻikoʻi i ka ʻōnaehana insulation.I ka wā o ke kūkulu ʻia ʻana, kau ʻia ka papa polystyrene welding wili wela wela ma loko o ka pā o waho e ninini ʻia, a ola ka papa insulation waho a me ka pā i hoʻokahi manawa.
Nā ʻano o ka ʻupena wili: ʻupena wiliwili, ʻupena hoʻoheheʻe kila, ʻupena hoʻoheheʻe PVC, ʻupena hoʻoheheʻe plastik, ʻupena wili i uhi ʻia, ʻupena hoʻoheheʻe ʻia, pa wili, ʻupena kuʻihao, ʻupena hoʻohiwahiwa, ʻupena kuʻuna moʻomeheu, ʻupena wili, hao. upena wili, upena uwea uwea eleele, upena uwea kii uwea, upena weawe wela, upena kuoo anu, upena wili pa, upena moe seedling, upena uwea kila, upena wili hao, upena mining, upena wili hale, wili. ʻUpena Dutch, ʻupena pāpaʻa pā, ʻupena hoʻoheheʻe paia waho, ʻupena kuʻihao, ʻupena kuʻihao kila, pale kuʻi haʻalulu, kaʻina hana kuʻihao ʻupena, ʻupena kāʻei pōhaku, kuʻi ʻana i ka hale pōhaku, ʻupena ʻōmaʻomaʻo, hoʻoheheʻe wela ma hope o ke kuʻi ʻana i ka ʻupena PVC, galvanizing. ʻupena wiliwili, ʻupena wiliwili ma mua o ka wiliwili ʻana, ʻupena wiliwili kila kila, ʻupena kaha kiʻi uwea a me nā huahana moʻo ʻupena ʻē aʻe.
He kuleana koʻikoʻi ko Galvanized uila kuʻihao ʻupena i ke kūkulu ʻana i ka insulation a me ka ʻenehana pale ʻana.Ua māhele ʻia ka pena kiʻi o waho a me ka ʻupena pāpaʻi i ʻelua ʻano:
ʻo kekahi he ʻupena kuʻi uila wela (lōʻihi ke ola, ikaika anti-corrosion hana);Kekahi hoʻololi no ke kaha kiʻi uea upena (economic mea hoʻoikaika 'ia, laumania ili, keʻokeʻo a me ka nani), e like me nā koi o ka wahi, ke kukulu hale e hana i kupono mea koho, pena i ka hana welded uwea mesh kiko'ī: 12.7 x 12.7 mm, 19.05 x19.05 mm, 25.4 mm x25.4, anawaena kilika ma waena o 0.4 0.9 mm
