M-3 & Associates, Inc. began in 1987 as a distributor to the overhead door industry. In 1995, a dual-spring assist system was designed for enclosed trailer ramp doors. The dual-spring system provided new levels of safety and ease of adjustment. Our spring assist systems proved so popular that the company gradually left the overhead door industry and concentrated on the enclosed trailer market.

As part of our growth in the enclosed trailer market, M-3 & Associates has introduced a line of products that include, aluminum recessed halogen and LED lighting, aluminum cam and bar locks, under-the-floor storage boxes in various sizes and in floor motorcycle wheel chocks..

M-3 & Associates entered the recreational vehicle industry in 2007 with the acquisition of Michiana Metals.  A complete line of galvanized HVAC products became available at the time.  A powder-coated steel bunk bed ladder was soon added to the product line.  Our ladder is uniquely angled so that the rectangular tube steps are parallel to the floor.  This angle and the stock application of anti-skid tape to the rungs offer a new level of comfort and safety.

A variety of custom metal products are also offered to the recreational vehicle, bus, box truck, and ambulance industries.  Examples are stake pockets, microwave brackets, sliding cabinet bases, battery trays, LP tank and generator compartment enclosures.

M-3 continues to focus on quality products with prompt delivery. The staff of M-3 & Associates, Inc. are committed to offering innovative solutions and new ideas in addition to providing the highest quality component parts available. We also provide educational support in the proper use and installation of our products.
