The advantages of using Corten steel

Corten steel is the trade name of a steel alloy that is associated with use in structures that require weathering materials. If left uncoated, Corten steel develops a patina that protects it from any additional corrosion. Here are the advantages of using this steel and some of the potential applications.

Benefits of using Corten steel

Its atmospheric corrosion resistance makes it a suitable material in applications in which painting is not desired. This makes it ideal for architectural and structural purposes, such as bridges, open-framed buildings, transmission poles, and Corten metal garden sculptures and planters (

Corten steel’s heat resistance makes it suitable for use in applications in which materials are required to withstand high heats, such as flues, chimneys and high-temperate ducts. It can be used above 400 degrees, which is the temperature at which normal steel becomes oxidised. Corten forms a patina at this temperature and can safely be used at temperatures as high as 450 degrees.

Cost effective

There are many reasons why using Corten steel is a cost-effective option. As the material creates its own patina, it requires no further painting, which will save a lot of time and effort over the lifetime of the building. This is an issue that can be problematic with other weathering steels. Repainting a bridge, for instance, can be an expensive and difficult undertaking. Savings can be made by using Corten for bridges and other similar structures for this reason.

Minimal maintenance

As the steel does not require painting, the structure will require cleaning and inspection only as part of its regular maintenance. If the structure is difficult to access, such as bridges and transmission poles, this can be a huge advantage. Minimum disruption will be required for inspection. This has an impact on the infrastructure, meaning less disruption to traffic and any transmissions during the maintenance.

Minimal construction

Where paint is not being used in its production or during its fabrication, the time frame is decreased. This gives you access to your structure, such as those designed by, more quickly.

In addition to Corten being cost effective and easy to maintain, it improves with age. As it is unpainted, it blends with its environment and changes over time, making it an excellent material for art installations.
