1.Nā hale kūkulu hale: Hoʻohana mau ʻia nā wili kila ʻōwili wela ma ke ʻano he mea hana hale, e like me ke kila, aluminika a me nā pale kila galvanized i hoʻohana ʻia e hana i nā hale, nā paia a me nā papahele.Loaʻa i kēia mau mea i ka ikaika kiʻekiʻe a me ka pale ʻana i ka corrosion a hiki ke hoʻokō i nā pono o nā hale i nā ʻano kūlana kaiapuni.
2.Hana kaʻa: ʻO nā kaʻa kekahi wahi noi nui no nā coils HRC.Hoʻohana ʻia lākou e hana i nā ʻāpana e like me nā kino kaʻa, nā puka, nā hood, nā hale a me nā chassis.He koʻikoʻi koʻikoʻi ka ʻoihana kaʻa no nā mea me ka ikaika kiʻekiʻe, rigidity a me ka corrosion resistance, ʻo ia mau mea āpau he mau hiʻohiʻona o ka ʻōwili wela wela.
