What is black corten steel ?

Black corten steel has undergone a specialized surface treatment to achieve a dark, black appearance. Regular corten steel develops a natural rust patina when exposed to weather elements. This creates a characteristic reddish brown color on the surface.

However, corten steel black is intentionally treated to accelerate the weathering process and achieve a uniform black color.

The blackened appearance provides a striking and contemporary look which makes it popular in architectural and design applications. This steel retains the same weather resistance and durability as regular corten steel and is suitable for various outdoor uses. Corten steel black sheet

How do you make corten steel black sheet ?
  • The surface is thoroughly cleaned to remove any dirt, oil or contaminants.
  • A mild acid solution is applied which reacts with the metal to remove some protective rust layer and expose the fresh metal beneath.
  • It is rinsed to neutralize any remaining acid and then dried completely.
  • A weathering accelerator or proprietary solution is applied to the surface.
  • The corten steel is left to naturally weather, and over time, a black rust patina develops which results in a black corten steel sheet
