What is corten steel?

Corten steel is high strength, low alloy weldable structural steel with exceptional weathering resistance. Corten steel is becoming more popular by roll formed product end-users. Its unique look and naturally oxidizing finish make it especially desirable for many architectural projects.

Weathering steel,is a group of steel alloys which were developed to obviate the need for painting,the chemical composition of the steel allows for the creation of a layer of rust that coats a building without altering the mechanical characteristics of the steel,and form a stable rust-like appearance if exposed to the weather for several years. Weathering steel has increased resistance to atmospheric corrosion when compared to other steels.

This rust layer,not only protects architectural steel products against the elements,but also delivers a unique finish that stops most people in their tracks. What’s more, it’s also more environmentally-friendly than traditional steel.

Corten steel 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.

Due to the high corrosion resistance of Corten Steel, it is also used to make flanges or other products, and then used in shipbuilding and offshore engineering. Hebei Haihao Group has specialized in production of steel forged flanges for more than 30 years. We have rich experiences. Of course, we can manufacture flanges with corten steel, carbon steel, stainless steel and alloy stell. If your projects also need flanges with these steels, please contact us!
