Leum Engineering, Inc. was founded by Grant Leum. Grant began his career as an engineer for Rite Hite Corporation in the early 1990's. At Rite Hite, his roles expanded to that of manager and eventually product development manager. During his tenure at Rite Hite Corporation, Grant helped invent and patent several new products. He also designed and supported many of their current product lines in the loading dock business.

	In 2002, Grant Leum founded Engination, LLC., a consulting engineering company focused on product development for small companies. As opportunities arose to begin designing and manufacturing new variations on existing loading dock products, Grant refocused the company's direction to concentrate more on manufacturing than consulting. This shift led to the corporate name change to Leum Engineering.

In 2006, Leum Engineering, Inc. developed the Z-Deck™ truck leveler, which revolutionized the way automotive drop decks trailers could be loaded. This product line as well as the company's core competency of engineered loading dock solutions brought Leum Engineering back in contact with Rite Hite to create a partnership that could allow both parties to bring the best products and services in the industry to market.

Leum Engineering's corporate sales and engineering are located in Excelsior, Minnesota, just west of Minneapolis. Manufacturing is done at two locations, one outside of Milwaukee, Wisconsin and another north of Detroit, Michigan. Leum Engineering's partnerships with excellent manufacturing facilities bring flexibility and short lead-times along with delivering high quality products. The combined manufacturing facilities bring over 100,000 sq. feet and 90 employees to effectively support the project requirements of our customers, regardless of project size.
