Depending on the complexity of the piece, the design can take minutes or several hours. The project is imported into a computer, edited and sized until it is ready for cutting. We use a CNC plasma cutting system. Plasma is a combination of oxygen and electricity, which produces a spark that burns away the material.
Once the piece is cut it must be cleaned. This requires grinding both the back and front (dross removal) of the piece. We use two kinds of steel. Hot rolled steel is typically used with the thicker pieces and must be cleaned first by soaking in muriatic acid and water. This removes the mill scale. It is then rinsed with water and dried with compressed ai, then ground front and back. Using cold rolled steel eliminates the acid cleaning but is more expensive.
After grinding, many of our pieces have more decorative grinding to make them appear dimensional and unique. We continue to explore various color options including heat coloring using a torch, and hand staining, as well as other patina finishes to make our work one-of-a-kind. Most of our work has a powder coat finish that can be a color or clear coat over the heat colored pieces, that makes our product durable for outside.
