Unpainted applications are not only offer the economic advantage of reducing repainting costs they also offer aesthetic benefits associated with the calming color of the protective rust.ĬOR-TEN is paintable in the same way as ordinary steel. Thanks to high weather resistance, corten steel can be used without painting. 3-5mm mild steel will also last a fairly long time in any garden, irrespective of the conditions.Ĭorten steel garden edging is the best option for for decorative screens for garden bed and edging system, as it develops a natural earthy patina. The question you can ask when buying such ornaments is whether it’s made of weathering steel and if it’s not, then look at the thickness of the actual steel used. Simply put, that steel isn’t designed for lasting outside in the elements and as it begins to rust, it can rust away quite quickly. Steel garden ornaments are often made with a thin gauge mild steel because it’s easy to cut and can therefore have more fine detailing. There is a difference between simply just letting steel rust in your backyard and real corten steel.
Weathering Steel was originally designed for for rail cars in the 1930’s but soon became popular for bridges and other large outside structures for the look and to eliminate the need for painting instead they had a stable rust layer on the surface, brought on by time in the weather. The COR relates to corrosive resistance while the TEN relates to it having high tensile strength.

The way this quality is achieved is by allowing corten to rust which causes it to protect itself.Ĭorten steel is a group of steel alloys which were developed to eliminate the need for painting and form a stable rust-like looks after several years exposure to weather. CORTEN pronounced Cor-ten, is also known as weathering steel, is premium steel due to its high level of corrosion resistance and density, due to the fact it has formed a protective oxide layer when exposed to the weather.
