The Signs and Plaques that we create are not castings from a foundry. Atlas Signs and Plaques have a base of modern 30 pound High Density Urethane (HDU) sign board. This is a product that was developed for the aerospace industry and has been used for signage for over 40 years. We coat our HDU signs and plaques with a cold applied, real metal coating that is used thoughout the world. It is a well-proven, tough, and beautiful coating that gives the look of cast metal without limitations. Our Signs and Plaques are very durable, but will not stand up to repeated abuse. If you wish to embed a plaque in the ground, hit it with a mower, or look at it in 500 years, you should order a foundry-cast plaque. Expect to pay 4-5 times as much as the affordable plaques we create using our proven methods. When you receive your order, you will notice that it is lighter weight. Since it is HDU with a thin metal coating, it is light and easy to hang on any wall without fear of testing the building’s structural integrity. We have our work, outside, at the U.S. Coast Academy and at locations over the world. You will even see our accomplishments at the new United States Capitol Visitor Center in Washington which has metal coated HDU in highly visible locations. In fact, you have probably observed metal coated HDU, but were unaware that you weren’t looking at a foundry casting. Bottom line is architects and designers realize this as a well tested, and well accepted process, and use it without hesitation at some of the worlds most prestigious properties. With a Sign or Plaque from Atlas, you will receive a quality product with the look and many of the characteristics of a foundry cast piece. You will have a truly custom product that is Made In the USA using American materials and labor. You will receive exceptional customer care from the very owners and craftspersons that are creating your selection. We want you to be thrilled with your purchase!
