Understanding Corten Steel
Before diving into its applications, let’s briefly discuss what Corten steel is and its key characteristics.
What is Corten Steel?
Corten steel is a group of steel alloys designed to form a stable rust-like appearance when exposed to the elements. The name “Corten” is derived from the two key properties of the material: CORrosion resistance and TENsile strength.
This weathering steel develops a protective patina over time, which not only gives it a distinctive rustic look but also helps prevent further corrosion.
Key Properties of Corten Steel
- Excellent corrosion resistance
- High tensile strength
- Self-healing protective layer
- Distinctive rustic appearance
- Low maintenance requirements
