Natural aluminum numbers and letters are water-jet cut from flat sheets of aluminum in the various thicknesses mentioned in the table above. The faces of these pieces are then brushed or polished. The returns (sides) are bead-blasted. As a final step, the numbers and letters are coated and baked with a clear, powder-coat.
NOTE: Brushed aluminum has a low gloss coat. Upon request, a high gloss can be provided.
