Corten is a corrosion resistant steel, that left uncoated develops an outer layer patina. This patina protects the steel from additional corrosion.

Because Cor-Ten steel has high weather resistance, it can be used without painting. Unpainted applications not only offer the economic advantage of reducing repainting costs; they also offer aesthetic benefits associated with the calming color of the protective rust.
While weather resistance depends on the product grade and the application environment, Cor-Ten steel’s weather resistance is nearly 4-8 times that of ordinary steel.
Cor-Ten steel is paintable in the same way as ordinary steel. In addition, even if a painting defect should occur, Cor-Ten steel suppresses the progress of rust area and, accordingly, prolongs the service life of the paint, thereby reducing repainting costs.
While trace amounts of alloying elements such as copper (CU) and chromate (Cr) are added to Cor-Ten steel to ensure high weather resistance, the carbon content is lowered to provide appropriate weldability. Accordingly, Cor-Ten steel can be welded using either manual, gas-shield or submerged arc welding. In addition, spot welding can be applied to thin-gauge Cor-Ten steel.
Cor-Ten steel possesses workability (cold forming, hot forming and gas cutting) similar to ordinary steels of same strength.
The mechanical characteristics and the resistance to atmospheric corrosion make this steel, the best product for the fabrication of agricultural vans and railway wagons, structures of bridges, water pipes, fans, chimneysand boilers.
The material forms its own protective layer when exposed to atmospheric elements. Essentially, the top layer corrodes and then protects the steel beneath it. The natural finish does not normally require any form of maintenance such as painting, which makes the material a highly cost effective alternative to other structural steels.
Mainly used for construction of tanks, containers, bridges, frame structures, vehicles, etc with the request of welded, bolted, etc.
