    Corten steel sheet (also known as weathering steel) is instantly identifiable thanks to its rich, bright orange tones. Originally developed for building coal carriages in 1930s America, it is now one of the most stylish and durable metals on the market. Corten steel plate might look like it’s rusty, but thanks to clever manipulation in its processing, the outer oxidisation actually protects the steel from further corrosion, as well as making it look very good indeed.

    The picture shows our natural/raw Corten sheet when first purchased and typically what it looks like after the weathering process, which takes between 3 months – 2 years after exposure to the elements.
