Our steel panels unique look and naturally oxidizing finish make it especially desirable for many architectural projects. Weathering steel has increased resistance to atmospheric corrosion when compared to other steels. It resists the corrosive effects of rain, snow, ice, fog, and other meteorological conditions by forming a coating of dark brown oxidation over the metal, which inhibits deeper penetration and negates the need for painting and costly rust-prevention maintenance over the years.
In simple terms the steel is allowed to rust and that rust forms a protective coating that slows the rate of future corrosion.
