Nws feem ntau yog siv rau hauv kev lag luam thiab kev siv hluav taws xob siv hluav taws xob qhov twg corrosion tsis yog qhov teeb meem loj. Cov txheej txheem galvanizing ntxiv cov txheej txheem tiv thaiv zinc rau cov yeeb nkab steel los pab tiv thaiv corrosion. Txawm li cas los xij, qhov no tsis yog qhov tsis muaj kev nyab xeeb thiab corrosion feem ntau yog qhov teeb meem.
