S355J0W steel yog huab cua tiv taus hlau uas tuaj yeem raug hu ua "Atmospheric Corrosion Resistant Steel" thiab feem ntau hu ua Corten-B steel. Huab cua txhais tau hais tias vim S355J0W steel tshuaj muaj pes tsawg leeg, S355J0W steel tshuaj muaj pes tsawg leeg tuaj yeem ua rau muaj kev tiv thaiv atmospheric corrosion piv rau lwm cov hlau. Qhov no yog vim nws tsim cov txheej txheem tiv thaiv ntawm S355J0W steel nto nyob rau hauv lub zog ntawm huab cua.
