In February 1974, with just a truck and a welder, Olen Beitzel and his father, Lawrence struck out on their own as Beitzel Welding. From humble beginnings in Lawrence’s garage they laid the foundation for a journey that would span five decades of growth and success.

As the years unfolded, the company evolved, reflecting the vision and dedication of its founders and growing number of employees. In 1978, the Beitzel Welding and Construction Company was officially incorporated, with Olen Beitzel assuming the role of principal owner. The transition marked a pivotal moment, signifying the company’s commitment to expanding its services beyond welding. The fabrication shop in Bittinger was constructed to serve as headquarters and provide shop fabrication support to the field crews.

The company continued to grow and expand throughout the 1980’s. Recognizing the diversified nature of its operations, the company underwent a name change on April 17, 1989, to Beitzel Corporation, accurately encapsulating its broader scope beyond welding and construction.

Now, in 2024, Beitzel Corporation proudly celebrates its 50th anniversary—a testament to the attitude, ambition, and ability of the Beitzel team. From its beginnings in coal, Beitzel has diversified into oil & gas, solar, aggregates, manufacturing, and other industrial markets.

As Beitzel Corporation commemorates this remarkable milestone, we not only reflect on our rich history but also look forward to a future filled with continued success, growth, and a legacy that transcends generations. Most importantly, we want to thank each and every employee who made 50 years possible. Without the vision, dedication, and hard work of our team none of this would have been possible.
