For centuries, bronze has been used to make plaques that are designed to last through the ages (as well as for sculptures, bells and many other objects.) A new bronze plaque can give an impression of importance and permanence unmatched by other materials. Aluminum plaques give a somewhat more modern impression, with text and borders in a silver-gray color, rather than the golden hues of bronze. These plaques can be used indoors or outdoors, with mounting hardware for all types of walls. Garden stakes and ground posts are also available.
Cast (or machine-tooled) plaques are frequently used for special recognition, for commemoration, appreciation or dedication, or as a memorial. They may also project a very upscale look when used as a sign to identify a business, school, residence or church.
Metal plaques can also have etched copy into a substrate of stainless steel, brass, bronze or copper metal. Etching allows for signs with more detailed text or images than what is possible with casting, and is more practical when a thinner metal material is desired.
