The power of Corten steel

The reason that our Outdoorovens are covered with a thick layer of rust is not only because it is a nice addition to a robust product; this very special kind of steel is called ‘Corten steel’ and this layer of rust gives the Outdooroven the opportunity to protect itself better against all types of weather. Corten steel, also known as COR-TEN steel or weathering steel, is a group of steel alloys which were developed to eliminate the need for painting and form a stable rust-like appearance, even after several years of exposure to weather influences. This new steel type was named COR-TEN because of the properties: COR (corrosion resistant) and TEN (tensile strength). Your Outdooroven is therefore able to protects itself against wind and rain, and further oxidation is prevented.

What makes Corten steel so special?

The idea behind this striking material is the formation of a surface layer of rust, protecting the steel from corrosion and eliminating the need for paint. By covering the product with a very dense rusted oxide skin it shields the deeper material from oxygen, which greatly slows down the oxidation proces. The corrosion-retarding effect of the protective layer is produced by the particular distribution and concentration of alloying elements in it. The layer protecting the surface develops and regenerates continuously when subjected to the influence of the weather. In other words, the steel is allowed to rust in order to form the protective coating. The result is a almost maintenance-free material with a unique aesthetic.

 

The Angel of the North

Partly due to the strong character of corten steel and its special appearance, the material is used in many different applications. Corten steel is used amongst others as facade covering for buildings, in civil engineering it’s used for bridges and sea containers, and it is also a material which is widely applied in art pieces. One of the most famous artworks is The Angel of the North; a contemporary sculpture designed by Antony Gormley, located in Gateshead in Tyne and Wear, England. The statue is 20 meters tall, the wings measure 54 meters width and the complete Angel is made of Corten steel. Because of its location it must be able to resist wind gusts of up to 160 km/h, rain and sun. The Angel of the North has been around since 1998 and has become a true icon for the region.
