4mm Corten Steel Sheet
Buying Options
Corten steel sheet (also known as weathering steel) is instantly identifiable thanks to its rich, bright orange tones. Originally developed for building coal carriages in 1930s America, it is now one of the most stylish and durable metals on the market. Corten steel plate might look like it’s rusty, but thanks to clever manipulation in its processing, the outer oxidisation actually protects the steel from further corrosion, as well as making it look very good indeed.
The picture shows our natural/raw Corten sheet when first purchased and typically what it looks like after the weathering process, which takes between 3 months – 2 years after exposure to the elements.

About 4mm corten steel
Corten steel is a type of high-strength, low alloy carbon steel that gains its characteristic orange-brown hue through a natural weathering process that develops over the course of 3-10 months. As the steel is exposed to the elements, it forms a protective oxidised layer that shields the underlying metal from further corrosion. This process not only gives Corten its distinct look but also makes it exceptionally weather-resistant.
Weathering steel is made from a blend of nickel, copper, and chromium. These elements combine to form a stable patina, which protects the steel from rust and damage, even in challenging outdoor conditions. Unlike traditional steel, Corten steel doesn’t require painting, coatings, or treatments to maintain its resilience, making 4mm Corten steel sheets a popular low-maintenance option for various projects.
Key properties of 4mm Corten steel sheets:
- Formability: Good
- Weldability: Good
- Machinability: Excellent
- Corrosion Resistance: Fair (improved by the patina)
Please note that your 4mm Corten steel sheet will arrive in its raw, grey state and will begin to develop its signature rust-like appearance after exposure to outdoor conditions. For those looking for a pre-rusted finish, we also offer pre-weathered Corten steel sheets.
