Weathering Steel
ASTM-A606 Type 4 Weathering Steel, also commonly known as Corten®️ Steel, forms a protective rust-like patina over time, making it ideal for architectural and structural applications. It’s made up of copper, chromium, nickel, and other elements that create the corrosion resistance properties.
What is Weathering Steel?
Weathering Steel is is designed to form a stable, protective rust-like patina when exposed to the atmosphere. This patina acts as a barrier against further corrosion, eliminating the need for painting
or additional surface treatments in many environments. Commonly used in bridges, building facades, railway wagons, and architectural structures, weathering steel combines durability
with a distinctive, evolving aesthetic that blends naturally with its surroundings.
