The Weathering Steel Finish
How it comes
The manufacturing process of weathering steel will leave the surface in a dark, almost black state. The weathering process sees this layer break down first before the desired protective patina layer can establish.
What it turns into
Once installed, wash with warm soap and water to remove the protective coating and encourage development of an even patina - this may take weeks or months depending on weather conditions.
