A combination of its unique look and its inherent robust properties make it an ideal material for a huge range of uses. From Antony Gormley’s Angel of the North to almost every RHS garden show in recent times, you’ll see Corten steel in more places than you might think. The name comes from Cor – meaning the corrosion resistance of the material and ten – the metal’s tensile strength.
That’s while you’ll see Corten sometimes written as Cor-ten steel. It’s also known as weathered steel as that’s exactly what it is.
Corten steel has a thin layer on the outside that oxidises, or rusts. It gives the steel its signature looks but also protects the steel within from further corrosion.
While it may look rusty, that layer is exceptionally thin but dense enough to fully protect the steel underneath.
So that’s the what and how, now let’s cover the what.
10 popular uses for Corten steel in the garden
