Cor-ten Architectural Siding Title & Map
Also known as “weathering steel” the trademarked product Cor-ten has become prominent in progressive architecture here in North America. Cor-ten was originally developed from a group of alloy steels which eliminate the need for finishing or painting. The product develops a thin skin of rust which actually protects the inner layers of steel from the elements. This skin continues to rust and weather over time and achieves different appearances depending on the environment, location and exposure. Cor-ten steel is available in many structural cross sections as well as plate and corrugated panels. Technical data on Cor-ten can be found here. Although Cor-ten has been used since the 1960’s in applications of structural necessity and high exposure it has only come to prominence in the architectural industry within the last decade. We’ve rounded up 16 residential projects in North America that use Cor-ten as an exterior skin – in some applications it is the actual envelope, in others it is applied as a rainscreen. Let us know about your favorite Cor-ten projects out there.

The Prospect in San Diego by Jonathan Segal
While some of the structural steel is Cor-ten the exterior is said to be of typical steel just rusting away. There is a very nice blog post on this project here.
