LMI Manufacturing has been built on consistent, on-time delivery of our quality products to our customers throughout the United States. Many of our existing customers have been with LMI for over 25 years for these reasons. They have the confidence that their parts will arrive as scheduled and trust they are made to their specifications. We fabricate everything in our 40,000 square foot building, located in Hartford, Wisconsin. Our experienced staff works with customers in the Waukesha, Milwaukee, Madison and surrounding areas to provide them with their needs for custom metal fabrication, machining, laser cutting, welding, and tube bending.
