Metal Exchange Corporation (MEC) is the flagship of a growing, global family of companies focused on aluminum and other nonferrous materials.   Founded in 1974, we are privately held, headquartered in St. Louis, MO, and have six US manufacturing facilities, as well as sales offices throughout the US and international offices in both Shanghai and Zurich.  Our business includes marketing, trading, manufacturing, processing, distribution and transportation services.   As a family owned company, our employees make the difference.  We're large enough to have the relationships and resources to be an industry leader, yet small enough for individuals to make a difference.
