What is Metalphoto? Metalphoto was developed for the U.S. Navy and is suitable for use in extreme environments. It is the most economical alternative among outdoor metals. Letters, lines and photos are not raised but impregnated into the pores of the smooth metal surface creating a permanent, scratch-resistant image. Metalphoto plaques in outdoor environments should maintain their integrity for about 20 years or more before the image begins to fade due to ultraviolet rays (actual lifetime will vary with exposure to sunlight). Metalphoto plaques are available in gold, silver, and copper finish (not shown).  Fonts, metals and styles, and artwork can all be customized to your desired specifications.
