What is Corten?

COR-TEN® steel is the preferred choice of roll formed product end-users. Its unique look and naturally oxidizing finish make it especially desirable for many architectural projects.

Weathering steel is a group of steel alloys developed to obviate the need for painting, and form a stable rust-like appearance if exposed to the weather for several years.

Western States Metal Roofing is the leader in metal roofing and siding products that look old and weathered. Our company specializes in buying Corten in large quantities and than passing those cost savings on to the end user. In addition, we have developed some nice looking painted panels designed to replicate the look of a real Corten, patina’d copper, or an aged galvanized finish We have stunning colors that actually look like real patina’d metal. There is no other company in the industry that has an equal color selection or authenticity of paint prints.

We are a family business that was started in 1996. Our company started as a distributor of metal decking and we transitioned to a roll former of metal roofing. As we started to develop our product line we began to sell a lot of Corten and bare cold rolled steel ( Real Rusted Roofing ). Continually, we were asked the same three questions:
  1. How come it is not already rusted ?
  2. Why is there no warranty ?
  3. How do I prevent rust stains?
It became very clear that there was a need for BOTH real rusted roofing and painted products that look rusted. From that point forward it has become our mission to be the leader of real rusted roofing and painted products that look patina'd.

We also have a large selection of corten components:
