What is the bleeding phenomenon?

Bleeding refers to the release of rust from Corten steel when exposed to moisture or rainwater, especially during the early stages of its use.
When Corten steel is exposed to water, some of the rust it contains can be released and flow along its surface, making it appear as if it is "bleeding." This process is most common during the first few months after installation, when the steel develops its protective patina.


Cortena products are all delivered oxidized so the bleeding time will be shortened compared to the raw state.


Bleeding can be a cosmetic problem, especially if it occurs on adjacent surfaces such as walls or floors, as it can temporarily stain these surfaces. However, it is usually temporary and diminishes as the Corten steel develops its protective patina.


To minimize bleeding and its potential effects, you can:


1. Clean Adjacent Surfaces Regularly: By cleaning surrounding surfaces regularly, you can reduce the buildup of rust released by Corten steel.


2. For planters, you can cut pieces of carpet and place them underneath to protect the surface.


3. Install Gutters or Siding: In architectural applications, the use of gutters or siding can help channel water away from adjacent surfaces, reducing the risk of rust stains.


4. Allow the patination process to complete: Over time, Corten steel will develop a more stable protective patina that will reduce bleeding. It is therefore important to let the skating process take its course.


5. Apply Protective Products: Certain protective products can be applied to Corten steel to help minimize bleeding and speed up the slippage process.

By following these tips, you can reduce the effects of bleeding associated with Corten steel and enjoy its many aesthetic and functional benefits.
