No nā wili galvanized, ua hoʻokomo ʻia nā ʻāpana kila lahilahi i loko o ka ʻauʻau zinc i hoʻoheheʻe ʻia e hoʻopili ai i kahi papa o ka ʻili kila zinc ma ka ʻili.Hoʻopuka nuiʻia ia e ka hana galvanizing mau,ʻo ia hoʻi, hoʻokomo mauʻia ka pā kila i'ōwiliʻia i loko o ka pahu pahu me ka zinc i hoʻoheheʻeʻia e hana i ke kila kila;pā kila galvanized.Hana ʻia kēia ʻano pā kila ma ke ʻano wela wela, akā ma hope koke o ka puka ʻana i waho o ka pahu, ua hoʻomehana ʻia a hiki i 500 ℃ e hana i ka uhi ʻana o ka zinc a me ka hao.Loaʻa i kēia coil galvanized adhesion pena maikaʻi a me ka weldability.
(1) Hoʻopili spangle maʻamau
I ka wā o ke kaʻina hana paʻa maʻamau o ka papa zinc, ulu manuahi nā hua zinc a hana i kahi uhi me kahi ʻano spangle maopopo.
(2) Hoʻemi ʻia ka uhi ʻana o ka spangle
I ka wā o ka hoʻopaʻa ʻana o ka papa zinc, ua kaupalena ʻia nā hua zinc e hana i ka uhi spangle liʻiliʻi loa.
(3) Spangle-free spangle-free coating
ʻO ka uhi i loaʻa ma ka hoʻoponopono ʻana i ka haku mele ʻana o ka hoʻonā plating ʻaʻole ʻike ʻia ka morphology spangle a me kahi ʻano like ʻole.

Hoʻomaʻamaʻa wela i ke kaula kila ma hope o ka hele ʻana i loko o ka ʻauʻau galvanizing e hana i kahi papa huila o ka zinc a me ka hao a puni ka uhi.ʻO kahi uhi hiki ke pena pololei me ka ʻole o ka hoʻomaʻemaʻe ʻana.
(5) Ka uhi ʻokoʻa
No nā ʻaoʻao ʻelua o ka pepa kila galvanized, pono nā uhi me nā paona ʻokoʻa zinc.
(6) Holo ka ʻili paheʻe
ʻO ka hele ʻana o ka ʻili kahi kaʻina hana anu i hana ʻia ma luna o nā pale kila galvanized me kahi liʻiliʻi o ka deformation no hoʻokahi a ʻoi aku paha o kēia mau kumu.
E hoʻomaikaʻi i ka hiʻohiʻona o ka ʻili kila galvanized a i ʻole kūpono no ka uhi ʻana;ʻAʻole ʻike ka huahana i ke ʻano o ka slip line (Lydes line) a i ʻole crease i ka wā o ka hana ʻana e hōʻemi i kahi manawa, etc.
