It is even possible to completely prevent the corten steel oxidising with an anti-rust coating. You can control the process and slow down or accelerate the appearance of the patina. Natural corten steel allows you to be creative. Please note that if you want to solder corten steel, you will need corten-specific MIG solder wire. ![]() On arrival, this means you can assemble projects by welding or screwing several metal plates together. Corten steel panels are sold as milled steel so we can avoid damaging the laser head during cutting. It can be sheared, punched, folded and laser cut. Why does my corten steel come without rust?Ĭorten steel is quite easy to work with for all types of projects. It gives corten steel a grainy appearance and different shades often accentuate its aesthetic appearance.Įxample of a head: milled corten steel in the process of oxidation The patina matures in 3 years maximum all by itself. The high concentration of corrosive products in this environment prevents the rust stabilising. For example, sea air does not create an effective protective layer. Bad weather can also slow or disrupt its formation. The orange-brown coloured patina that forms this way is not perfectly consistent all over. When this layer matures, it no longer gets any marks and makes the steel less permeable. The succession of wet and dry periods acting on corten steel thus produces corrosion on the surface until a layer of resistant and protective metal oxide forms. The addition of the alloys mentioned above produces more stable rust that adheres better. The rust process is exactly the same for corten steel, except that it doesn’t regenerate itself. When it dries, this layer of rust becomes porous and detaches from the metal leaving room for a new cycle of rust to weaken the metal. On conventional steels, rust forms on the surface of the metal sheet with moisture and air. Due to the presence of phosphorus, this protective layer regenerates continuously on the surface and forms a barrier against moisture, oxygen and pollution. This patina usually forms in 1 to 3 years, depending on the environmental conditions and the alternation of wet and dry periods that help the patina adhere. ![]() These alloys increase the corten steel’s resistance to atmospheric corrosion by creating a protective patina on the surface. ![]() How does corten steel rust? The composition of rusty steelĬorten steel is a steel with added phosphorus, copper, chromium and nickel-molybdenum. Its name « COR-TEN » comes from its two main properties: CORrosion resistance and TENsile strength. Due to its chemical properties, rusty corten steel is also known as weathering steel and self-healing steel. Corten steel is a metal that changes over time under the influence of atmospheric conditions. Once it has matured, this layer of metal oxide is called a « patina ». The coloration is due to the self-protecting rust layer that naturally forms over time. It is found particularly in building (architecture and construction), in public spaces (street furniture) or to make upmarket works of art, signs, chimineas and fire bowls.Ĭorten steel is a brown-orange steel.
