ʻO ka hoʻohana ʻana i nā pā alumini no ke kaʻa pahu aila
Hoʻopili ʻia ka pā alumini no ke kino pahu me 5083 alumini alumini pā. ʻO ka mānoanoa o ka pā he 5-6mm.
ʻO nā ʻāpana ʻē aʻe e like me ka papa holoi holoi, bulkhead a me ke poʻo pahu he 5083 pā alumini. ʻO ka mānoanoa pā o ke poʻo pahu pahu he like a ʻoi aku paha ma mua o ke kino o ka pahu. ʻO ka mānoanoa o ke poʻo a me ka papa holoi he 1mm ʻoi aku ka lahilahi ma mua o ke kino pahu.
ʻO ka mānoanoa o nā papa kākoʻo hema a me ka ʻākau ma lalo o ka pahu he 6-8mm, a ʻo ka mea he 5A06 pā alumini. Aia nā kiaʻi a me nā paepae hele wāwae ma luna o ka pahu. Hana ʻia nā paepae hele wāwae me ka pā alumini
ʻO ka mea hana pāʻani alumini, mea hoʻolako pāʻani alumini, hale hana pāʻani alumini
Q: He hui kālepa a mea hana paha ʻoe?
A: He hale hana mākou.
Q: Pehea ka lōʻihi o kāu manawa hoʻouna?
A: ʻO ka maʻamau he 3-5 mau lā inā loaʻa nā waiwai. a i ʻole he 25-35 mau lā inā ʻaʻole i loaʻa nā waiwai, e like me ka nui.
Q: Hāʻawi anei ʻoe i nā laʻana? He manuahi a keu paha?
A: ʻAe, hiki iā mākou ke hāʻawi i ka hāpana no ka uku manuahi
Q: He aha kāu mau ʻōlelo uku?
A: Keʻae nei mākou iā T / T, LC, Western Union, Paypal, Alibaba Credit Insurance Order, etc. Hiki ke kūkākūkāʻia keʻano o ka uku e nāʻaoʻaoʻelua e like me ke kūlana maoli.
