Ever wanted to know more about corten steel and why it’s become such a popular choice for construction and landscaping? In this article, we’ll discuss its properties, composition, uses, and more. So if you are looking for an in-depth look at corten steel, read on!
What is Corten Steel?
Also known as weathering steel or COR-TEN (Corten), corten steel is a unique alloy that can form a protective layer when exposed to the environment. The outermost layer corrodes and forms a barrier that prevents further oxidation from occurring. This protective layer stops any further rust from forming and keeps the structure intact for years to come.
Corten Steel Composition
Corten steel is composed of various alloy elements, including copper (Cu), chromium (Cr), nickel (Ni), phosphorus (P), manganese (Mn) silicon (Si).

Corten Steel Properties
Corten steel has many desirable properties. It is strong and durable, making it an ideal material for construction projects like bridges, buildings, monuments, and sculptures. Additionally, its rustic appearance makes it popular for use in landscaping projects where its natural beauty can be highlighted. Corten steel also has excellent resistance to corrosion, meaning that it won’t corrode or rust when exposed to moisture over time. Lastly, because of its unique composition of alloy elements, including copper and chromium, corten steel can withstand high temperatures without warping or melting.
