Corten is no longer produced in the united states.
Cor-Ten® is a trade name for a steel alloy material originally produced by United States Steel.
Corten is a weathering steel. This material is a corrosion resistant steel, that left uncoated develops an outer layer patina. This patina protects the steel from additional corrosion. It is a high strength steel alloy, and it is used where higher strength and longer life cycle material were desired.
As Cor-Ten became more popular over the years other producing mills began to develop their own atmospheric corrosion resistant weathering steels. ASTM stepped in and created what is considered equivalent specifications to Cor-Ten® in most applications.
The applicable equivalent ASTM specifications are ASTM A588, A242, A606-4, A847 and A709-50W, which Central Steel Service supplies in various products including, sheet, coil, plate, steel flats, angles, channels, pipe & tube.
Central Steel Service specializes in the applications for Corten as well as the ASTM weathering steel materials which replace it for any application. Call our in house experts for recommendations.
