ʻO ka uhi ʻili o kēia pepa galvanized he 55% aluminika, 43.5% zinc a me kahi mea liʻiliʻi o nā mea ʻē aʻe.Nānā ʻia ma lalo o kahi microscope, hoʻokumu ʻia ka ʻili o ka uhi i kahi ʻano honeycomb, a ʻo ka honeycomb alumini ka zinc.
ʻOiai e hāʻawi nā pale galvanized i ka pale anodic, aia kekahi mau palena.Me ka hoʻemi ʻana o ka zinc a me ke kāʻei ʻana o ka alumini a puni ka mea zinc, e emi ana ka electrolysis.Eia nō naʻe, ʻo ia hoʻi ke ʻoki ʻia ka pepa galvanized, e pōʻino ka papa pale, a hiki i ka ʻoki ʻoki i ka pala.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 ana anti-rust, e like me ka pena anti-rust a i ʻole ka pena waiwai zinc.
