Photo anodized Aluminum Nameplates and labels are produced using a photo imaging process that seals the image within the sapphire hard anodic layer of the aluminum which resists chemicals, paint, abrasion and dirt. Unlike surface printed products, photo anodized Aluminum Nameplates and labels offer durability even in the most extreme environments, plus with a special intensification process they can last outside for 20 plus years. This optional secondary coating also increases the heat resistance of the Aluminum Nameplates or label.
