Corten steel common name for corten steel

Corten steel, also known as weathering steel, is an alloy of steel commonly used for outdoor construction projects. Rusted steel eventually develops a rusted appearance as it is exposed to the elements.

During the 1930s, U.S. steel developed a product called Corten Steel. It was originally designed to help build railroad coal wagons. Coal wagons became a popular medium for outdoor art projects in the 1960s because of their success.

The weathering resistance and elegant look of Cor-ten Steel make it a material of choice for architects. Its high strength and weldability make it an excellent weathering-resistant steel for a variety of projects. Its characteristic orange-brown rusted look adds to the structural steel’s tasteful appearance. Due to its mechanical properties, Cor-ten can be used to construct lighter structures using well-established design practices with the advantage of improved weatherability.

The steel gets its weathering resistance from the formation of a protective oxide coating which seals the surface against further corrosion. Whenever Cor-ten® Steel is damaged or chipped away, it repairs itself to maintain its appearance and protection. This self-repairing feature makes it the perfect choice for projects where maintenance is difficult. In addition to reducing maintenance and repair costs, steel creates a protective coating that effectively slows corrosion, saving time and money on painting. Additionally, Cor-ten offers extra corrosion protection to damaged unpainted areas, as well as reducing corrosion under the paint, which is known as creep.

Applications of Corten Steel


Because of its resistance to weathering, long life, and incredible strength, Corten Steel is increasingly being used in landscaping and gardening. Corten Steel’s orange-brown finish is very on-trend at the moment. Corten Steel can also be used to make a big impact in a small space. It was widely used in the Chelsea Flower Show’s award-winning gardens.


Cor-ten is used for bridge construction and rail electrification. The Ordsall Chord bridge in Manchester uses Corten for its iconic look. It was chosen for its architectural and industrial finish and low maintenance requirements in a challenging location.

The bridge is built in the city center and required high architectural quality along with practical installation and maintenance solutions in a railway, river, and road environment. As the first asymmetric network arch in the world, the architects used weathering steel to create the appearance of a single ribbon, providing a striking and low-maintenance finish.


Aside from its sturdy yet malleable nature, the material has an idiosyncratic visual appeal, which is why many artists have fallen in love with it. Sculptors continue to use cor-ten in order to create stunning and appealing works of art that will gracefully withstand the test of time because of their distressed antique appearance and ability to blend perfectly into the environment.
