ʻO ke kila Corten kahi kila kahi i hoʻohui ʻia ai ka phosphorus, keleawe, chromium a me nickel molybdenum. Hoʻomaikaʻi kēia mau mea hoʻohui i ke kūpaʻa corrosion o ke kila Corten ma ka hana ʻana i kahi papa pale ma ka ʻili. Hāʻule ia i loko o ka ʻāpana o ka hōʻemi ʻana a i ʻole ka hoʻopau ʻana i ka hoʻohana ʻana i nā pena, nā primers a i ʻole nā pena i nā mea e pale ai i ka pala. Ke hōʻike ʻia i ke kaiapuni, hoʻomohala ke kila i kahi ʻāpana keleawe-'ōmaʻomaʻo e pale i ke kila mai ka ʻino. ʻO ia ke kumu i kapa ʻia ai kēia kila corten steel.
Ma ke kaiapuni pono, e hana ke kila corten i "slurry" pale pale e pale ai i ka corrosion. He haʻahaʻa loa ka nui o ka corrosion a hiki i nā alahaka i hana ʻia mai ke kila corten i pena ʻole ʻia e hiki ke hoʻokō i ke ola hoʻolālā o 120 mau makahiki me ka mālama inoa wale nō.
ʻO ke kila Corten he haʻahaʻa ke kumukūʻai mālama, lōʻihi ka lawelawe ʻana, ikaika practicability, wela a me ka corrosion. ʻAʻole like me ke kila kila, ʻaʻole ia e ʻā. ʻO ke kila hoʻoheheʻe wale nō ka ʻoki ʻana o ka ʻili a ʻaʻole komo i loko o ka loko. Loaʻa iā ia nā waiwai anti-corrosion o ke keleawe a i ʻole aluminika. I ka hala ʻana o ka manawa, ua uhi ʻia ia me kahi pale anti-corrosion kala; ʻO kahi pahu waho i hana ʻia me ke kila corten he nani, lōʻihi, a pono ka mālama liʻiliʻi.
