ʻO ka uhi ʻili o kēia pepa galvanized ua hana ʻia me 55% alumini, 43.5% zinc a me kahi liʻiliʻi o nā mea ʻē aʻe. Ke nānā ʻia ma lalo o kahi microscope, hana ka ʻili uhi i kahi ʻano meli, a loaʻa i ka meli alumini ka zinc.
ʻOiai ʻo nā uhi galvanized e hāʻawi i ka pale anodic, aia kekahi mau palena. Me ka emi ʻana o ka nui o ka zinc a me ka ʻōwili ʻana o ka alumini a puni ka mea zinc, lilo ka electrolysis i mea emi. Eia nō naʻe, ʻo ia hoʻi ke ʻoki ʻia ka pepa galvanized, e hōʻino ʻia ka papa pale, a hiki ke ʻōpala ka ʻaoʻao ʻoki. I mea e hoʻolōʻihi ai i ke ola lawelawe o ka pā, ua ʻōlelo ʻia e hōʻemi i ka ʻoki ʻana a lawe i nā hana anti-rust, e like me ka pena anti-rust a i ʻole ka pena waiwai zinc.
