Oxidized Copper numbers and letters are water-jet cut from flat sheets of copper in the various thicknesses mentioned in the table above. The faces of these pieces are then brushed. The returns are bead-lasted. Next, the pieces are oxidized by submersion in a chemical solution to darken the copper into either a medium or dark finish.
As a final step, the returns are tinted a very dark brown hue; then, the returns and faces are coated and baked with a glossy 2-part hardened acrylic polyurethane clear coat.
Our solid, oxidized, copper numbers and letters are cut from lead and mercury-free copper alloy C11000.
Reminder: The photos on this page are representative samples. The photos were shot in direct mid-day sunlight. Under less intense lighting such as indoor illumination, the underlying copper color may not be so intense.
In addition, your custom order will be oxidized uniformly as a single batch. However, different custom batches may show different intensities of oxidization.
