Corten steel is an alloy steel that contains the key three elements nickel, copper and chromium, and typically has a carbon content of less than 0.3% by weight. Its lighter orange color is mainly due to the copper content, which over time is covered with a copper-green protective layer to prevent corrosion.

Corten’s popularity can be attributed to its strength, durability, practicality, and aesthetic appeal.Corten Steel has many advantages, including maintenance and service life. In addition to its high strength,corten steel is a very low maintenance steel. Because Coreten Resist the corrosive effects of rain, snow, ice, fog, and other meteorological conditions by forming a dark brown oxidizing coating on the metal, thereby inhibiting deeper penetration and eliminating the need for paint and expensive rust maintenance over the years. Simply put, steel rusts, and rust forms a protective coating

Corten steel resists the corrosive effects of rain, snow, ice, fog, and other weather conditions by forming a dark brown oxidizing coating on the metal surface. Corten steel is a type of steel with added phosphorus, copper, chromium, nickel and molybdenum. These alloys improve the atmospheric corrosion resistance of weathering steel by forming a protective layer on its surface.

Corten steel will not rust. Due to its chemical composition, it exhibits higher resistance to atmospheric corrosion than mild steel. The surface of the steel will rust, forming a protective layer that we call "patina."

Corten steel are a family of mild steels that contain additional alloying elements mixed with carbon and iron atoms. But these alloying elements give weathering steel better strength and higher corrosion resistance than typical mild steel grades. Therefore, corten steel is often used in outdoor applications or in environments where ordinary steel tends to rust.

Corten steel is a steel to which phosphorus, copper, chromium and nickel molybdenum have been added. These alloys improve the atmospheric corrosion resistance of Corten steel by forming a protective layer on the surface. It falls into the category of reducing or eliminating the use of paints, primers or paints on materials to prevent rust. When exposed to the environment, the steel develops a copper-green keep-active layer to protect the steel from corrosion. That's why this steel is called corten steel.
