Corten (or COR-TEN) steel eliminates the need for painting or coating the metal by creating a stable rust-like appearance which develops over time from exposure to weather, a solution which can considerably extended the lifespan of the metal.

Its uses and applications are diverse and innovative – from garden planters and lawn edging to building cladding and roofing. Sheet Corten steel can be laser cut into intricate designs to make for beautiful artworks and distinctive screens.

For one of the most iconic and well-known uses of Corten, look no further than the Angel of the North in Gateshead, created by artist Antony Gormley.

The typical surface oxidation of weathering steel takes approximately six months, but surface treatments can be applied which accelerate the oxidation with the rust-like coating developing in a few hours.

The layer protecting the metal’s surface develops and regenerates continuously when subjected to the weather – in other words, the steel is allowed to rust in order to form the protective coating.

Unlike rust, the weathered surface of Corten does not flake or transfer off the metal when touched or rubbed making it a clean and very attractive solution.

Background to Corten
In 1933 the United States Steel Corporation developed and patented a steel with exceptional mechanical resistance, primarily for use in railroad hopper cars, for the handling of heavy bulk loads including coal, metal ores and other mineral products.

The name Corten refers to the two distinguishing properties of this type of steel: corrosion resistance and tensile strength.
