Corten steel: the weatherproof structural steel

The basis

Corten steel is a special steel alloy that differs from conventional steel due to the addition of copper, chromium, nickel and phosphorus. These elements cause a dense, firmly adhering layer of rust to form on the surface of the steel when exposed to the weather. This layer protects the steel from further corrosion and makes additional coatings or paints superfluous. The corrosion resistance of Corten steel is therefore significantly higher than that of ordinary structural steel.

The formation of patina: natural protection

The characteristic rust layer that gives Corten steel its distinctive appearance develops over a period of several months to years. The steel goes through various phases of oxidation until a stable protective layer is formed. Weather influences such as rain, wind and temperature changes are decisive for this process. Once the patina has fully formed, the corrosion process virtually stops, making the steel particularly durable.

The application: Architecture, art and industry

Thanks to its unique appearance and high resistance, Corten steel is used in many areas. It is particularly popular in architecture for façades, bridges and sculptures. It is also used in garden design, for example for privacy screens, planters or decorative elements. In industry, Corten steel is used for structures that have to withstand extreme weather conditions, such as bridges or offshore facilities.

The material: sustainability and aesthetics

Corten steel not only impresses with its technical properties, but also with its sustainability. As it does not require any additional coatings or paintwork, it reduces maintenance costs and conserves resources. It is also fully recyclable, making it an environmentally friendly choice. Its warm, rusty coloring gives it a timeless aesthetic that makes it versatile in both modern and traditional designs.

Corten steel is more than just a building material - it is a combination of functionality, durability and design. A material that changes over time and yet remains durable. You can also find numerous Corten steel products in our store! Take a look around and order your products today!
