What is Corten made of?

Corten steel (a.k.a. weathering steel) is an ideal metal material for many outdoor applications.
Civil structures, load-bearing structures, and general outdoor construction components and parts are made from corten steel since they can withstand and remain durable in harsh environmental conditions.
The material can last a long time.
Its ability to last for years and in some cases, decades, when exposed to outside elements is largely due to its capacity to regenerate a protective and highly corrosive-resistant coating within a few months to a few years of exposure.

How Is Corten Steel Made? The corten steel manufacturing process begins with a blending of three primary plates of steel-copper, chromium, and nickel-along with other alloying elements like phosphorus, silicon, and manganese.
