Weathering steel, tseem hu ua corten steel, yog cov khoom siv zoo kawg nkaus uas tau txais kev nyiam nyob hauv ntau qhov chaw vim nws cov khoom tshwj xeeb.
Hom hlau no yog tsim los tsim kom muaj qhov ruaj khov zoo li xeb zoo li lub sijhawm thaum raug cov khoom. Cov txheej txheem oxidation tsim cov txheej txheem tiv thaiv uas ua rau qeeb ntxiv corrosion, ua rau nws ruaj khov heev. Tsis zoo li cov hlau ib txwm siv uas yuav tsum tau saib xyuas tsis tu ncua thiab pleev xim kom tsis txhob xeb, huab cua steel txuag cov nqi tu mus ntev.
