ʻO ke kila kila, i ʻike ʻia ʻo ka ʻili kila. Hoʻopiliʻia ke kila e ka paʻi wela a me ke anuanu. I mea e maʻalahi ai ka mālama ʻana a me ka lawe ʻana a me nā ʻano hana like ʻole. ʻO ka wili i hoʻokumu ʻia ʻo ia ka nui o ka wili wela a me ka wili anuanu. He huahana i hana ʻia ma mua o ka recrystallization billet. ʻO Cold Rolled Coil ka hana ʻana o ka coil rolled hot. ʻO kā mākou hale hana ka mea nui e hana a hoʻohana i ka coil rolled cold rolled. ʻO ka wili kila, ka wili kala kala a me kā mākou mea kūʻai hui e kauoha maʻamau i ka wili kila me ke kaumaha ma kahi o 25-27t. Ke hoʻomau nei ka hoʻonui ʻia ʻana o ka mana o ka ʻōwili wela o Kina, aia he mau kakini o nā laina hana ʻōwili wela, a ua kokoke e kūkulu ʻia a hoʻokomo ʻia kekahi mau papahana. No ka laʻana, kūʻai aku mākou i ka dx51d Z100 galvanized steel coil well.

ʻO ka ʻōwili uhi kala kahi huahana i hoʻokumu ʻia ma luna o ka pā wela wela, ka pā alumini zinc wela a me ka pā uila uila. Ma hope o ka hoʻomaʻamaʻa mua ʻana o ka ʻili (ka hoʻoheheʻe ʻana i ke kemika a me ka hoʻololi ʻana i ke kemika), hoʻokahi a ʻoi aʻe paha o nā ʻāpana o nā mea hoʻonaninani i uhi ʻia ma ka ʻili, a laila kālua ʻia a paʻa. Ua kapa ʻia ʻo ia ma hope o ka ʻili kila kala i uhi ʻia me nā kala like ʻole o nā mea hoʻonaninani kūlohelohe, i kapa ʻia ʻo coil coated color no ka pōkole. Ma waho aʻe o ka pale ʻana o ka zinc layer, ʻo ka uhi kūlohelohe ma ka papa zinc he kuleana nui i ka uhi ʻana a me ka pale ʻana i ke kala i uhi ʻia i ke kala kila me ka wela wela e like me ka mea kumu, i mea e pale ai i ke kaula kila mai ka ʻōpala. ʻO ke ola lawelawe ma kahi o 1.5 mau manawa ʻoi aku ka lōʻihi ma mua o ke kaula hao galvanized. ʻO ka'ōwili kala i uhiʻia he māmā ke kaumaha, nani keʻano a me ka hana anti-corrosion maikaʻi, a hiki ke hana pololeiʻia. Hoʻokaʻawale ʻia ke kala i ke keʻokeʻo hina, uliuli moana a me ka ʻulaʻula pōhaku. Hoʻohana nui ʻia ia i ka ʻoihana hoʻolaha, ʻoihana kūkulu hale, ʻoihana mea hana hale, ʻoihana uila uila, ʻoihana lako a me ka ʻoihana kaʻa.

ʻO ka uhi i hoʻohanaʻia i ka'ōwili'ōwili kala e koho i ka resin kūpono e like me ka hoʻohanaʻana i nā mea likeʻole, e like me ka polyester silicon modified polyester, polyvinyl chloride plastic sol, polyvinylidene chloride, etc. Hiki i nā mea hoʻohana ke koho e like me ke kumu.
