ʻOiai ʻaʻole hiki ke hoʻopilikia ʻia ka ʻeleʻele ʻeleʻele a i ʻole ka 'ele keʻokeʻo' i ka hiki ke pale ʻia o kahi uhi galvanized, he mea maʻalahi ia e pale aku.

Hiki ke ʻeleʻele waihona pulu ke ʻike ʻia nā mea hao hou i ka makū e like me ka ua, ka hau a i ʻole ka condensation (ke haʻahaʻa kiʻekiʻe), a noho i kahi me ka liʻiliʻi o ka ea ma luna o ka ʻili.Hiki i kēia mau kūlana ke hoʻopili i ka hana ʻana o ka patina pale.

ʻO ka maʻamau, hana mua ka zinc me ka oxygen e hana i ka zinc oxide, a laila me ka wai e hana i ka zinc hydroxide.Me ka ea maikaʻi, hoʻololi ka zinc hydroxide i ka zinc carbonate e hāʻawi i ka pale pale i ka zinc, no laila e hoʻolōʻihi i ka nui o ka corrosion.Eia nō naʻe, inā ʻaʻole hiki i ka zinc ke komo i ka ea kahe manuahi a noho mau i ka makū, hoʻomau ka zinc hydroxide ma kahi o ka hoʻomohala ʻana i kahi ʻeleʻele waihona pulu.

Hiki ke ulu aʻe ka ʻōpala keʻokeʻo i nā pule a i ʻole i ka pō inā pololei nā kūlana.I loko o nā kaiapuni koʻikoʻi, hiki ke puka mai ka ʻeleʻele hoʻopaʻa wai mai nā waihona paʻakai o ka ea i hoʻopaʻa ʻia e komo i ka makū i ka pō.

Hiki i kekahi kila galvanized ke hoʻomohala i kahi ʻano ʻeleʻele waihona pulu i kapa ʻia ʻo 'black spotting', i ʻike ʻia he mau kiko ʻeleʻele me ka ʻeleʻele pauka keʻokeʻo a puni.ʻOi aku ka maʻamau o kēia ʻano pehu waihona pulu ma luna o ke kila anana māmā e like me nā lau, purlins a me nā ʻāpana hollow pā lahilahi.ʻOi aku ka paʻakikī o ka hoʻomaʻemaʻe ʻana ma mua o nā ʻano maʻamau o ka ʻōpala keʻokeʻo, a i kekahi manawa ʻike ʻia ke kiko ma hope o ka hoʻomaʻemaʻe ʻana.
