I have a specifier who has client that wants to use Corten roofing for a shopping center project. We have discussed some of the pros and cons of Corten. Can anyone offer futher advice for using this product? Also, can anyone direct me to a source for acquiring the product (mfg., dist., installer, etc...) Project is located in Paso Robles, CA.

Basically Cortan is steel that is designed to oxidize (rust) which then prtotects the stel. Provided it is used in an application and an environment that does not cause the oxidation to be remove it will provide a reasonable service life. It is very bad in overlap situations and in snow and ice regions. Be prepared for stained fascias, concrete walks etc and in this day and age they do not want this in the sewers. I would try an inquiry to US Steel as they do make this type of steel however when I investigated it for a product line they basically would not provide it any more for roof material. The next problem is to get a manufacturer to run it in the profile requested. If the Architect wants aged steel, it is better to buy some G40 agricultural panels and acid etch them. Sory I can't be of more help and more positive.

regarding the G40 panels with an acid etch to achieve a rusted metal look. After etching the surface, is there a way to seal and protect the material from simply continuing to rust through? Thanks for any advice.

Sorry, this is what Corten is all about, red oxidation. If you are really into this, then buy thiscker steel to provide a longer life span. US~ Steel who originally created the product now has a painted metal version that looks the same but will last a lifetime. Contact them.
