Loaʻa i ka Steel grating nā mea maikaʻi o ka mālama ʻana i ke kila, ka pale ʻana i ka corrosion, ke kūkulu wikiwiki ʻana, ka maʻemaʻe a me ka nani, non-slip, ventilation, ʻaʻohe dents, ʻaʻohe wai hōʻiliʻili, ʻaʻohe lepo, ʻaʻohe mālama, a me ke ola lawelawe ʻoi aku ma mua o 30 mau makahiki. Ke hoʻohana nui ʻia nei e nā hale kūkulu hale. Hoʻomaʻamaʻa ʻia ka ʻili o ke kila kila, a ma hope wale nō o kekahi hana kūikawā hiki ke hoʻonui ʻia kona ola lawelawe. ʻO nā kūlana hoʻohana o ke kila kila i nā ʻoihana ʻoihana ka hapa nui o ka lewa a i ʻole ma nā wahi me ka lewa a me ka corrosion medium. No laila, ʻo ka hoʻomaʻamaʻa ʻana o ke kila kila he mea nui i ke ola lawelawe o ke kila kila. Hōʻike ʻia nā ʻano hana lapaʻau maʻamau o ka ʻili kila.
(1) Wehe-wela galvanizing: Hot-dip galvanizing ʻo ia ka hoʻokomo ʻana i ka pahu kila i hoʻoneʻe ʻia i loko o kahi wai zinc hoʻoheheʻe kiʻekiʻe ma kahi o 600 ℃, no laila e hoʻopili ʻia kahi papa zinc ma ka ʻili o ka pae kila. ʻAʻole e emi ka mānoanoa o ka papa zinc ma lalo o 65um no nā papa lahilahi ma lalo o 5mm, a ʻaʻole emi ma lalo o 86um no nā papa mānoanoa. Ma laila e hoʻokō ai i ke kumu o ka pale ʻana i ka corrosion. ʻO nā mea maikaʻi o kēia ʻano hana he lōʻihi ka lōʻihi, ke kiʻekiʻe kiʻekiʻe o ka hana ʻana o ka hana, a me ka maikaʻi paʻa. No laila, hoʻohana nui ʻia i loko o nā papahana hoʻoheheʻe kila waho i hoʻopili nui ʻia e ka lewa a paʻakikī ke mālama. ʻO ka hana mua o ka galvanizing wela, ʻo ia ka pickling a me ka wehe ʻana i ka ʻōpala, a ma hope o ka hoʻomaʻemaʻe. ʻO ka pau ʻole o kēia mau ʻanuʻu ʻelua e waiho i nā pōʻino huna no ka pale ʻana i ka corrosion. No laila, pono lākou e mālama pono.
(2) ʻO ka alumini hoʻoheheʻe wela (zinc) i hoʻohuihui ʻia: He ʻano hana pale corrosion lōʻihi kēia me ka hopena pale corrosion like me ka galvanizing hot-dip. ʻO ke ʻano kikoʻī, ʻo ia ka sandblast mua i ka ʻili o ka paʻi kila e wehe i ka ʻōpala, i ʻike ʻia ka ʻili i kahi luster metala a me nā ʻano. A laila e hoʻohana i ka lapalapa ahi acetylene-oxygen e hoʻoheheʻe i ka uea alumini (zinc) i hāʻawi mau ʻia, a puhi iā ia ma luna o ka ʻili o ka pahu kila me ka ea paʻa e hana i kahi uhi honeycomb alumini (zinc) (ka mānoanoa ma kahi o 80um~100um). ʻO ka hope, e hoʻopiha i nā capillaries me nā uhi e like me ka cyclopentane resin a i ʻole ka urethane rubber pena e hana i kahi uhi hoʻohui. ʻO ka pōmaikaʻi o kēia kaʻina hana, ʻo ia ka mea hiki ke hoʻololi i ka nui o ke kila kila, a ʻo ke ʻano a me ka nui o ka pahu kila he aneane pau ʻole. ʻO kekahi pōmaikaʻi ʻo ia ka hopena wela o kēia kaʻina hana kūloko a paʻa, no laila ʻaʻole ia e hoʻololi i ka thermal deformation. Ke hoʻohālikelike ʻia me ka galvanizing hot-dip of steel grating, ʻoi aku ka haʻahaʻa o kēia ʻano hana, a ʻoi aku ka kiʻekiʻe o ka hana o ka sandblasting a me ka alumini (zinc). Hoʻopili maʻalahi ʻia ka maikaʻi e nā loli o ke ʻano o ka mea hoʻohana.
(3) ʻO ke ʻano o ka uhi ʻana: ʻAʻole maikaʻi ka maikaʻi o ka pale corrosion o ke ʻano o ka uhi ʻana e like me ke ʻano o ka corrosion resistance lōʻihi. He haʻahaʻa haʻahaʻa hoʻokahi manawa, akā he kiʻekiʻe ke kumukūʻai mālama ke hoʻohana ʻia ma waho. ʻO ka hana mua o ke ʻano o ka uhi ʻana ʻo ka wehe ʻana i ka ʻōpala. Ke hilinaʻi nei nā uhi kiʻekiʻe i ka wehe ʻana o ka ʻōpala. No laila, hoʻohana maʻamau nā uhi koi kiʻekiʻe i ka sandblasting a me ka pana kī e wehe i ka ʻōpala, e hōʻike i ka luster o ka metala, a wehe i nā ʻōpala a me nā ʻaila a pau. Pono e noʻonoʻo ke koho o ka uhi ʻana i ke kaiapuni a puni. He ʻokoʻa ka hoʻomanawanui ʻana o nā pale ʻokoʻa i nā kūlana corrosion. Hoʻokaʻawale ʻia nā uhi i nā primers (layers) a me nā topcoats (layers). ʻOi aku ka pauda a me ka mea kumu ʻuʻuku. ʻO ke kiʻiʻoniʻoni he ʻōkole, pili ikaika i ke kila, a maikaʻi ka hoʻopaʻa ʻana me nā topcoats. ʻOi aku ka nui o nā mea kumu, loaʻa nā kiʻiʻoniʻoni ʻoniʻoni, hiki ke pale i nā primers mai ka ʻino ʻana o ka lewa, a hiki ke pale aku i ka wā. Aia kahi pilikia o ka launa pū ʻana ma waena o nā ʻāpana like ʻole. Ke koho ʻana i nā ʻāpana like ʻole ma mua a ma hope, e hoʻolohe i ko lākou kūlike. Pono e loaʻa ka mahana kūpono (ma waena o 5 ~ 38 ℃) a me ka haʻahaʻa (ka haʻahaʻa haʻahaʻa ma mua o 85%). Pono e emi ka lepo o ka hale hana uhi a ʻaʻohe condensation ma ka ʻili o ka mea. ʻAʻole pono e ʻike ʻia i ka ua i loko o 4 mau hola ma hope o ka uhi ʻana. Hoʻohana pinepine ʻia ka uhi 4-5 mau manawa. ʻO ka nui o ka mānoanoa o ke kiʻi pena maloʻo he 150um no nā papahana o waho a me 125um no nā papahana i loko, me ka ʻae ʻia o 25um.
