ʻO nā ipu kanu kahi mea hana nui no ka ulu ʻana o nā mea kanu ʻōmaʻomaʻo. He kaiapuni ko kela mea keia mea kanu no kona ulu ana. Inā kanu ʻoe iā lākou i loko o nā ʻano ipu like ʻole, e hana lākou i nā hopena like ʻole. ʻO nā ipu pua kila Corten he corrosion-resistant, ʻoi aku ka lōʻihi o ka lawelawe ʻana a me ka pua nani. Hiki ke hoʻopilikino ʻia ke ʻano a me ke kala o ka ipuhao e like me nā koi, a hiki ke hoʻohana ʻia no ka hoʻonaninani o waho, ka hoʻonaninani pā, etc.

Hāʻawi ka ipu kanu kila Corten i kahi hiʻohiʻona ʻulaʻula ʻulaʻula ʻulaʻula e loli ana me ka wā a me ka manawa, e hana ana i ka haʻalulu ikaika me nā mea kanu ʻōmaʻomaʻo, e hoʻomohala ana i kahi ʻano kūlohelohe.

ʻO nā mea kanu kila corten i hana ʻia i ke ʻano o ke kila weathering, he 4-8 mau manawa ʻoi aku ka maikaʻi o ke kūpaʻa corrosion ma mua o ke kila maʻamau. -me kona hoʻolālā kaulike, ka lōʻihi, a me ka ʻoluʻolu - e hōʻike ana i kahi hoʻolālā modular hou i kūpono maikaʻi e lawe i kāu mea hoʻonaninani waho i kahi pae hou.
