#1 – IS IT CORTEN, COR-TEN, COR 10, OR WEATHERED STEEL?
Simply put – it all means the same thing. The generic term for the product is “weathered steel”. The word “COR-TEN” is a trademarked term for weathered steel and owned by U.S Steel. Any spelling variations such as “Corten”, “Cor Ten”, or ”Cor 10” are incorrect alterations of the trademark but still mean the same thing – weathered steel. ASTM standards for weathered steel are A588, A242, and A606-4.
#2 – ARE THERE SIZE LIMITATIONS FOR WEATHERED STEEL PANELS?
Yes. There are many things to take into consideration when determining panel size limitations for your project, such as attachment systems, oil canning, panel gauge, and framing. Since there are many different factors driving panel size limitations it really comes down to the unique conditions of your project. We are always happy to discuss the details of your project and help you determine the right size panel for your job.
#3 – ARE THERE PANEL THICKNESS LIMITATIONS WITH WEATHERED STEEL?
Yes. When weathered steel was in its early days as a solution for exterior cladding, it was discovered that going too thin was problematic. Corrosion layers would build on each side and eat all the way through panel. In time, ASTM standards were released that indicated weathered steel panels should be at least 16 gauge or thicker. Those standards are still in effect today, however, panel thickness is ultimately determined by many different project specific factors and can safely be thinner than 16 gauge.
