Corten is a material that is achieving extraordinary popularity and success. This is hardly surprising: it is versatile, visually appealing, and structurally resistant. It can be used as a cladding or a load-bearing element, for everything from a facade or a staircase to a small outdoor sign.

Its main characteristics are resistance to corrosion and tensile strength. It is a low-alloy material (originally composed of 0.2–0.5% copper, 0.5–1.5% chromium, and 0.1–0.2% phosphorus). It is not a recent innovation; the patent dates back to 1933, created by the American company United States Steel Corporation (U.S.S.). Initially used to line tanks and freight cars, it lasted up to four times longer than carbon steel.

However, we owe the first construction application as a structural steel to architect Eero Saarinen, who used it in 1964 for the John Deere and Co. World Headquarters in Illinois.

Corten steel protects itself from electrochemical corrosion. During oxidation, it releases a powder of alloying element oxides that coats the surface, forming a patina. This patina consists of a porous outer layer and a very thin, impermeable inner layer rich in copper, chromium, and phosphorus. The surface is matte and fairly uniform; generally, the sheets are installed pre-oxidized, but in some cases, elements are mounted while the oxidation is still in its early stages.

For this reason, it is referred to as a “living metal”: if the surface patina is damaged or scratched, the oxidation process restarts to form a new protective layer. Stagnant water, proximity to chlorides (such as seawater), and the application of waxes or paints halt its oxidation process, which is why the installation environment must be carefully evaluated. On the other hand, sunlight, alternating wet and dry cycles, and atmospheric exposure keep it alive, facilitating its natural changes in color and tone. It is non-deformable, fully recyclable at the end of its life cycle, and lends itself to various processing methods—such as forging, bending, drawing, laser cutting, and welding—making it extraordinarily versatile. Furthermore, it does not crack, decay, or require maintenance.

The only disadvantage can be water “runoff” (from storms or rain) which can stain adjacent surfaces, such as paving. It is therefore advisable to provide channels to collect rainwater runoff.
