Corten steel, also known as weather-resistant steel, is a unique type of steel that distinguishes itself by its exceptional corrosion-resistant properties. These properties are created by the addition of elements such as copper, chromium, and nickel to the steel. Thanks to this composition, Corten steel develops a protective oxidation layer over time, often recognizable by its characteristic rust-brown color. This layer ensures that further corrosion is prevented, making the material durable and low-maintenance.
When corten steel is exposed to different weather conditions, it begins its transformation process. This process leads to the formation of a dense barrier layer, consisting of sulfates and phosphates that adhere to the surface. Unlike ordinary steel, which rusts continuously, the rust process with Corten steel stops as soon as this protective layer has fully developed. This keeps the material strong and stable, even in the most challenging environments.
The most striking feature of Corten steel is its visual transformation. The material starts out with a grayish color, but quickly develops a warm, rust-brown patina. This unique appearance depends on several factors, such as temperature, humidity and the position in which the material is placed (for example vertical or horizontal). The complete formation of the protective layer usually takes about a year, but this process can be accelerated with special rust accelerators. For a lasting result, a rust fixer can be applied as soon as the steel is completely is rusted, which helps to prevent further rust formation and the release of rust water.
Corten steel is known for its exceptional strength and durability. It is one of the strongest types of steel available, which makes it particularly suitable for outdoor applications, such as garden elements, facade cladding, and works of art. A flower box made of corten steel, for example, is not only functional, but also an eye-catcher that gives both modern and classic gardens a warm and natural look. appearance.
Corten steel is an excellent choice for anyone looking for a combination of aesthetics, durability and ease of maintenance. Whether it concerns a garden, a facade, or a work of art, this versatile material offers a unique solution that adapts to its environment and only becomes more beautiful over time.
