Some of our Defense Industry Customers


Since 1960, Lanzen Incorporated has been supplying the Defense, Transportation and many other diverse industries with quality metal fabricated components and assemblies.  Lanzen's three Michigan manufacturing facilities located in the cities of Romeo, Mancelona & Harbor Springs (formerly Petoskey) are well equipped to meet the high standard of quality that our customers have come to expect. We invite you to learn about our prototyping and production capabilities by browsing the pages of our web site.  In July of 2017, Lanzen acquired the assets of Demmer Corporation’s Petoskey Machining operations, an acquisition that greatly expands our machining capabilities. The Petoskey facility was relocated to Harbor Springs in July 2019. In addition to our vertical machining capability, Lanzen now has turning, horizontal milling and 5 axis machining capabilities. The resources of all three facilities can operate independently, or by integrating today’s technologies, those resources can be combined to act as a single manufacturing stream. Pioneering ideas like this, in conjunction with innovative engineering, program management and a modern mix of production equipment and systems, has led to Lanzen’s long term growth and success. Our defense industry customers, include the US Government, BAE Systems, General Dynamics, Lockheed, Raytheon, AM General, and many others.   We manufacture metal assemblies and welded fabrications from carbon and alloy steel, armor plate, aluminum, titanium and copper in all shapes and many sizes.
