Corten steel (also called Weathering Steel) is a special steel which, after developing a thin coat of rust, is then so rust-resistant that it is used by engineers for bridge buliding. We think Corten is a terrific material for use in gardens. It has a superb reddish-brown rusty colour which sets off the shapes and colours of flowers and leaves - as the photographs show.
The beautiful colouring matures with age and is also dependent on it's environment. The patina can start with a golden copper and, especially if by the sea, will mature into an elegant auburn. The patina can be stopped from maturing with a sealer if required.
We like however for the patina to grow like the plants inside.
Due to the chemical make up of Corten, a very dense oxidisation layer is formed which protects the blue steel inside. If this protective barrier is comprised, it will simply form a new skin to protect itself.
Cor-ten was originally engineered for use in construction. Bridges, buildings and even buses all over the world are made with Cor-ten.
Completed in 1998 you can see the Angel of the North just outside Tyneside still standing strong above.
