It is not corten steeel and it is not copper, but it matches both. Various outdoor products now come in the new corten brown colour because they are often to match environments with classic building materials, such as brown bricks, corten steel, or copper. The name of the colour is Mars SX3050F and it is standard in the Akzo Nobels range, and consequently we charge no extra cost in comparison with other standard colours.
The products available in corten brown are shown below. Please do not hesitate to contact us, should you require other Focus products in this colour.
