Corten steel, or weathering steel, is renowned for its distinctive appearance and naturally oxidized finish. Although the material is low-maintenance once the protective coating has been applied, getting to that point might not be as easy.
The panel's surface develops a gorgeous rustic finish and texture after installation and exposure to normal weather conditions. Copper, chromium, manganese, and nickel make CorTen more expensive. Rain, snow, ice, fog, and other meteorological conditions do not corrode Cor-ten due to the coating of dark brown oxidation that forms on the surface, which inhibits deeper penetration and eliminates the need for costly rust-prevention maintenance over the years.
Various roofing manufacturers have been referred to as the "Cadillac of Roofing." Depending on your opinion of the manufacturer, this comparison could be less than flattering. Metal roofs are not a specific product, but rather a wide range of products.
