OUR COMPANY
For over 20 years, Imperial has presented America the highest quality mailboxes and street signs, and we have become synonymous with curb appeal. Situated in the heart of the American southeast, Imperial has continued to serve the finest communities, from Country Club of the South in Atlanta, to Broadmoor Resorts in Colorado, as well as Encore by WCI Communities in New York. As the leading mailbox manufacturer, Imperial was invited to co-author the U.S.P.S. Std 7b, which standardized the manufacturing of all residential mailbox systems.
Imperial has set the stage for excellence, not only in the manufacturing of mailboxes and signage, but also in customer service, engineering, market analysis, research and development, and governmental affairs.
We Are Beautifying America. We Are Curb Appeal. We Are Imperial.
History of Imperial
Imperial Mailbox Systems is a family owned manufacturing company that was formed in 1989. Emerging from ‘Imperial Door Systems’, a manufacturer of steel security doors and windows, founder John H. Clark Sr. identified a potentially more lucrative market in the form of residential amenities. Creating a line of cast aluminum mailboxes and street signs designed to standardize curbside amenities throughout residential communities, Imperial sought to meet the architectural demand for standardized mailboxes and street signs to enhance aesthetics and protection of property value.

The Early Days
With just four employees, less than 5,000 sq ft of warehouse and manufacturing area and shipping less than ten systems per week, Imperial engineered what would become the finest mailbox in America raising the bar in curb appeal. Currently, our manufacturing facility in Millbrook, Alabama is over 50,000 sq ft and ships more than 1,200 mailbox systems and accessories every week.
Post Master Approval (1995)
As our product quality has increased, so have our processes, which led to the implementation of a quality system conforming to ISO 9001:2000 standards. Working in conjunction with the United States Postal Service, Imperial was invited to co-author and implement the U.S. Postal Standard 7A, Mailboxes, City and Rural Curbside regulating the manufacture of all curbside mailboxes. Receiving the first ever Post Master Approval in 1995, we still maintain a close relationship with the Postal Service. More recently, in 2001, we were invited back to lead the USPS Curbside Mailbox Revision Consensus Committee to review the Standard 7A, and make appropriate changes.
Imperial Today
Our facility produces a product line of over 300 raw parts to manufacture the finest cast aluminum mailboxes, street signs, and lampposts. Imperial’s product has made its way into the finest planned communities in Alabama; including: Wynnlakes, Greystone, The Penninsula, Asheton Park, and Craft Farms. Beautifying these master planned developments we are also proud to have been a major part of other projects by developers such as: Daniel Corporation and Conner Brothers.
Moving Forward
Imperial has substantially enhanced these communities (as well as other of the most prominent communities throughout the United States) to such a degree as to enhance the beautification of the development, increase property value, and provide continuance in the value of the home, development, and community.
