Cast aluminum and bronze plaques are manufactured using sand molding process in our state-of-the-art foundry. All plaques are created with certified raw alloy ingot material. Bronze castings are the material of choice for interior as well as exterior applications because of the high copper content. Although the surface of bronze will naturally patina over time, the material itself will not deteriorate. The same product layout and design options are available for both bronze and aluminum plaques. Bronze plaques have a “reddish gold” appearance when polished; aluminum has a brushed silver look. Aluminum plaques may also have the raised areas hand painted in a variety of color options. Both materials are excellent choices for outdoor applications, many years of low maintenance service can be expected. We also offer refurbishing service for all metal plaques and markers, call us for details.
