Allan, can you say any more about the advantages/disadvantages of the cold rolled steel products that are out there? They tout their advantages over Cor-ten, but it sounds like you are doubtful? Can you explain a little more? Thanks!

Corten is a trade marked name for a type of steel owned by US Steel and there are other companies that have a similar steel. US Steel does not recommend this type of product for roofing unless you are in a desert where it never rains or snows and having personally seen some installations, I agree. There are too many down sides to using this type of substrate. US Steel does make a metalic coated steel, prefinished with a tp quality paint that closely replicates Corten's colour.

The product by USSteel is called Cor-ten AZP I can't seem to find pricing or approx. pricing on it though... do you have a clue where to get a ball park?

I would contact US Steel direct, either in Pittsburgh, PA or Fairhope, AL. Todd Miller

I've been looking for the Cor-ten AZP as well. Jenny, could you advise if you've had any success?

US Steel does not roll form or sell finished goods. You need to contact a metal roofing manufacturer and ask them if they carry that finish. Go to our member manufacturers listing on this site, chooses a profile and contact those manufacturers.

I'm thinking of using A588 sheet for a metal roof. Concerns over obtaining an initial "hard" rust seem easily overcome by allowing this process to take place (under controlled conditions) prior to installation. I have seen suppliers for industrial roof decking (eg, concreted roof) in A588 but none for expressed/residential metal roofing.

I do not know anyone producing panels for this type of application. Todd Miller

We use Cor-Ten roofing and siding all the time and we are in a high elevation, mountain climate; lots of snow and we get our share of rain. There is more than one type of Cor-Ten and the lesser quality/cost material doesn't hold up as well on roofs as the heavier. That said, when using the heavier material, these roofs have held up much better than asphalt shingles, wood shakes or many of the manufactured look-alike metal roofing products that tout long life. We have also found that the oxidation coating that forms 2-3 months after installation of the roof only slightly "weathers" off with snow/rain for a year or so and then stabilizes. The coating does not ever completely "wash off" and, therefore,doesn't recoat all the time. We expect these roofs to last a very long time with little or no maintenance. Allan, consider using your spell check before posting (seriously!).

usually when a customer asks for corten roofing or siding they are not really to worried about longevity. If they were concerned with life expectancy they would be asking for galvalume,copper, copper/stainless,terne, zinc etc.,etc--it's obvious that the "look" is much more important to them than the life expectancy or cost.
