Impact! Sign Letters uses only the highest quality aluminum, brass, copper, bronze, and stainless steel solid plate.   Letters and logos are router and waterjet cut out of solid plate metal, resulting in precise, razor sharp lines.

If the face of the metal letters are polished, the returns will be sanded. All other finishes will have bead blasted returns.

All cut metal sign letter products, if exposed to continuous rain, sprinkler systems, or other high moisture situations, mineral buildup may occur on the surface of the sign letters. Using harsh chemicals may cause permanent damage to the material's surface. Impact! Sign Letters recommends warm soapy water.
