What is blackened steel?

Blackened steel is a type of metal that has been chemically treated to create a dark, matte finish. The process of blackening steel involves treating the surface of the metal with an acid solution, which causes a layer of iron oxide to form on the steel. This layer of iron oxide is what gives the steel its distinctive black color.

Blackened steel is often used in architectural and decorative applications, such as for metal wall panels, roofing, and furniture. The finish is popular because it creates a modern and industrial aesthetic that complements a range of design styles.

While blackened steel is durable and resistant to corrosion, it is not as resistant to wear and tear as other finishes, such as stainless steel. Blackened steel should be sealed to protect it from scratching and other forms of damage. Some common sealing methods include oiling or waxing the surface, or applying a clear coat of protective sealant.
