Weathered Steel Features

The Rusting Process

Why Corten is Unique

The most practical benefit of weathered steel is its ability to avoid corrosion. When exposed natural elements, most steels have the tendency to rust. Eventually, the rust layer becomes weak and breaks off.

With corten the rusting process happens in the same way, but the steel produces a stable rust layer also known as a patina, which serves as a protective, corrosion-resistant barrier. This naturally-developed protective patina regenerates continuously when exposed to weather and stops further access of oxygen, moisture and pollutants. 

The rate at which this happens is very dependant on the elements. With that said rust will start to develop within a few weeks and patina formed between 6 months to a year.
