Is corten steel fire resistant?

Corten weathering steel is a type of steel that develops a protective layer of rust when exposed to atmospheric conditions.

The two main types of Corten steel are: Corten A, which is typically used for architectural purposes and Corten B, which has been impact tested meaning it is often used in structures.

1 - Corten weathering steels are corrosion resistant
Corten weathering steel has corrosion resistant properties that give it an advantage over other structural steels. Its naturally occurring rust helps to extend the life cycle of weathering steel structures, thereby minimizing costs.

2 - Buildings constructed with weathering steel require fewer coatings
Corten weathering steel forms a protective layer of rust when exposed to moisture and oxygen, reducing the need for paint. This helps avoid problems and potential damage caused by the volatile organic compounds found in some paints.

3 - Weathering Steel for Heavy Duty Structures
The strength and durability of Weathering Steel B makes it ideal for heavy and load-bearing structures.

4 - Corten Weathering Steel's Eye-Catching Appearance
Corten Weathering Steel produces a protective patina with a distinctive reddish-brown appearance that is particularly popular with architects and design engineers. It is commonly used for art, outdoor structures and modern applications.

5 - Corten steel requires minimal maintenance
Corten steel has more than just architectural properties. Due to its chemical composition, Corten steel is able to withstand high temperatures without increased corrosion, which means it's perfect for chimney liners, log burners and fireplaces.
