About Rauhorn Electric


About Rauhorn Electric, Inc.

Our field personnel, as well as our office staff, are highly qualified and are dedicated to providing our customers with superior installation and service.

Del Rau and Vic Horn started Rauhorn Construction. Gloria Rau gave the company its name, Rauhorn.


In July, Rauhorn Electric was formed. The first office was in the basment of Del and Goria’s home in Sterling Heights. In September of that same year, for $1,500, Del purchased the remaining 50% from his partner  to become the sole owner of the company.


Del purchased Rauhorn’s first bucket truck called a “Skyworker.” Rauhorn was prequalified with MDOT for electrical. The company also installed its first traffic signal at Telegraph and 13 Mile Road in Oakland County.


Rauhorn purchased its first building located at 24 Mile Road and Van Dyke.


In 1978, Rauhorn Construction was formed by a partnership between Owners Delbert J. Rau Jr. (“Del”) and Victor Horn. In 1980, Del became the Sole Owner and established Rauhorn Electric, Inc. Since inception, Rauhorn Electric, Inc. (“Rauhorn”) has been family owned and operated. We now have two generations of the Rau Family working for the company.

Over the years, Rauhorn grew to become a union electrical contracting company specializing in transportation-related electrical infrastructure in the state of Michigan.

Rauhorn gained a presence in the industry by installing traffic signals for MDOT. Over the years, we have become a trusted contractor for some of the most premier projects in the area. With diversification in trades and experience, Rauhorn has expanded our work into numerous capacities. Services provided include airport electrical, integration, intelligent transportation systems, overhead distribution and substation work, pump station electrical, site lighting, traffic signals and control systems, renewable energy, roadway/freeway lighting, and underground construction.

Rauhorn has been performing airport electrical infrastructure installation and maintenance since the early 90’s. As you travel out of Metro Detroit Airport, take a look at those little blue taxiway lights guiding your plane and think “Rauhorn blue” because there’s a good chance we installed them.

Due to our experience, safety statistics, and quality service, Rauhorn is a pre-qualified contractor with: DTE Energy, Consumers Energy, Michigan Department of Transportation (including a pre-qualification classifications for: (L) Electrical, (I) (N6) Signs and (I) Sodding and Seeding/Turf Establishment), Midwest Energy Cooperative, Traverse City Light and Power, PSEG Long Island, LLC and Cloverland Electric Cooperative.
