Pono ka papa galvanized e loaʻa kahi ʻili maikaʻi, ʻaʻahu a hoʻomau. ʻAe ʻia nā hemahema. E like me: nā kaha wai liʻiliʻi; nā hōʻailona paʻa liʻiliʻi ma nā wahi koʻikoʻi o nā ʻāpana; nā ʻokoʻa liʻiliʻi o ka waihoʻoluʻu a me ka ʻōlinolino ma ka ʻāpana like, etc. ʻAʻole ʻae ʻia nā hemahema. E like me: ka uhi ʻana i ka blistering, peeling, scorching, nodules and pitting; dendritic, spongy a me ka streaky coatings; nā meheu paʻakai i holoi ʻole ʻia, etc.
②Laʻana no ka nānā ʻana.
No nā ʻāpana koʻikoʻi, nā ʻāpana koʻikoʻi, nā ʻāpana nui a me nā ʻāpana maʻamau me ka nui o ka batch ma lalo o 90 mau ʻāpana, pono e nānā ʻia ka hiʻohiʻona 100%, a pono e haʻalele ʻia nā huahana kūpono ʻole; no nā ʻāpana maʻamau me ka nui o nā ʻāpana ʻoi aku ma mua o 90 mau ʻāpana, pono e lawe ʻia ka nānā ʻana i ka laʻana, e lawe maʻamau i ka pae nānā II, kūpono ʻO ka pae maikaʻi ʻo 1.5%, a ua hoʻokō ʻia ka nānā ʻana e like me ka hoʻolālā sampling hoʻokahi manawa no ka nānā maʻamau. i hoakakaia ma ka Papa 2-12.

③ʻO ke ʻano o ka nānā ʻana i ke ʻano a me ka loiloi maikaʻi.
Hoʻokumu nui ʻia ka nānā ʻana ma ke ʻano hiʻohiʻona. Inā pono, hiki ke nānā ʻia me kahi aniani hoʻonui o 3 a 5 mau manawa.
