Cov khoom siv zoo heev: Cov ntsia hlau no feem ntau yog ua los ntawm cov hlau zoo, ua kom lawv lub zog thiab kav ntev. Kev xaiv ntawm cov hlau kuj tso cai rau cov rau tes kom tiv taus ntau dua qhov nro thiab shear rog, haum rau ntau yam kev ua haujlwm hnyav.

Kev kho deg: Cov ntsia hlau nto yog polished thiab galvanized. Muaj ob txoj hauv kev tseem ceeb rau galvanizing: kub-dip galvanizing thiab electro-galvanizing. Kub-dip galvanizing yog ua kom tiav rau cov rau tes hauv cov kua zinc kom zinc tsim cov txheej tiv thaiv tuab ntawm cov ntsia hlau. Cov ntsia hlau kho los ntawm cov txheej txheem no muaj kev tiv thaiv corrosion zoo dua thiab tsim nyog siv rau hauv qhov hnyav sab nraum zoov lossis qhov chaw muaj av noo siab; electrogalvanizing yog phaj txheej zinc ntawm cov ntsia hlau los ntawm electrolysis. Cov txheej zinc no kuj yog nyias, tab sis cov tsos yog ci dua thiab zoo ib yam, uas yog tsim rau scenes xws li kho kom zoo nkauj sab hauv nrog siab xav tau rau cov tsos. Cov txheej txheem kev kho mob no txhim khu kev tiv thaiv corrosion ntawm cov rau tes, yog li txuas ntxiv lawv lub neej kev pab cuam.
