Bronze memorial plaques are the best way to honor the memory of a valuable contributor to your company. They remind employees of the hard work and dedication that went into making the company what it is today. Whether a custom plaque is placed in the lobby, a hallway, or above the door, it will serve as a permanent "thank you" to that individual who spent so much of his or her life serving the company.
While plaques can be made of many materials (wood and stone are common), bronze memorial plaques are the best choice for a high profile business dedication plaque. Bronze is the customary choice in memorial situations because it is the most elegant material available (short of gold or platinum.) It is also corrosion resistant. Typical bronze plaques will last hundreds if not thousands of years with little maintenance.
While most suppliers have a line of pre-designed plaques from which a company can choose, many suppliers are also able to custom design cast bronze plaques. Perhaps you are seeking to honor an employee whose dedication to the ecology around your headquarters was responsible for a beautiful park or garden. A plaque with a bas relief could be custom designed to honor their achievements.
Dedication plaques should not be obtrusive. While the past achievements of employees, donors, and sponsors should be remembered, oversized plaques can be gaudy and overbearing. Your honoree would not want to be remembered as the person responsible for the gigantic eyesore in the building's lobby.
