Initially specializing in four-fold door systems for industrial and commercial markets, the Minneapolis, MN company soon expanded to aviation and other unique/specialty door industries. In 1979, the organization moved to its current location in Kasota, MN. The already growing product line increased to include fire-rated door systems in 2003 when Door Engineering and Manufacturing, Inc. purchased American Metal Door. An investment consortium purchased Door Engineering and Manufacturing, Inc. from the Olson family in 2004 and changed the name to Door Engineering and Manufacturing, LLC. Today, with thousands of door systems worldwide and more than 40 years of experience, Door Engineering continues to be an industry leader in industrial, commercial, fire rated, aviation and specialty door solutions.
