Helpful Hints

bulletBronze castings are the material of choice for interior as well as exterior applications. Although the finish of bronze will naturally patina over time, the material itself will not deteriorate. Objects made from bronze have been found submerged in seawater for over 3000 years still in excellent condition.

bulletThe weight of a bronze plaque may be roughly estimated by calculating the plaque's volume in inches (height x width x depth) x .31. For most smaller plaques (under 36" x 30") allow .25" as the approximate depth. Use .375" for plaques over 36" x 30".

Example: For a 36" x 24" plaque calculate 36" x 24" x .25" = 216 cu. inches x .31 = 66.96. The plaque's estimated weight would be 67 lbs.

bulletAn aluminum plaque is approximately 1/3rd the weight of a comparable sized bronze plaque. In the above example, simply divide the answer by 3. A 36" x 24" aluminum plaque weighs approximately 23 lbs.
