how are the corten panels attached to the wall and what thickness did you use?

I am currently working on a new project and the client wants sheet metal siding. I have searched for awhile how others have attached the metal panels but have not found any worthy info. My project will have exposed rivet heads as part of the a design so I am having plain steel rivets custom manufactured so they will also rust and not stand out with a different finish. Our metal panels are only being used as a decorative façade and will be attached on top of the completed and sealed wall.

I have the same question as CH design. Any resources for details?

Although I have not seen any response from CH design yet, I have seen a few projects with Corten. A restaurant in San Diego wrapped the osb sheathing with Tyvek and then use 1" square tubing and built a framework that attached to the Tyvek covered osb. The Corten was then attached using self tapping screws. And another project, 16 gauge sheet metal base plates was attached to the Tyvek and then weathered steel sheet metal was placed on top of the base plates using a domed lag
