Louis Industries was started in 1940 as Louis Blacksmith Shop. Alfred Louis began by shoeing horses, fixing agricultural equipment, and doing general repair and maintenance for the local residents.

In 1973, Leo and Cecil Louis purchased the assets of the business from their father and changed the name to Louis Industries, Inc. They began to modify the scope of the company from a general blacksmith shop to an original equipment manufacturer that produced a line of wood burning stoves, hog and cattle equipment along with general manufacturing activities. In the early 1990s the focus of the company underwent a further change and began to deemphasize OEM work and integrate steel processing. In 1995, laser cutting was added to the list of capabilities and in 1999 the company moved into its current modern facility.
