JIS G3125 SPA-C Corten steel

SPA-C resists the corrosive effects of rain, snow, ice, fog, and other meteorological conditions. The surface of the metal SPA-C can form a coating of dark brown oxidation, which inhibits deeper penetration, so SPA-C steel save the cost of need for painting and costly rust-prevention maintenance over the years.
