The company, led by President Derrick VanDyke, was founded in 1956 and operates a 45,000 sq. ft. services, fabrication, and headquarters in Wheeling, West Virginia.
“We are pleased to announce the sale of Rohrig to Jennmar to further expand and strengthen our commitment to our loyal customers and employees,” said Mr. VanDyke. “We are confident that this partnership will enable continued growth, and bring our high-quality, cost-effective solutions to more customers across the industries we serve. We would like to thank all our employees and customers for the years of support and look forward to this next phase as a part of Jennmar.”
Jennmar is a manufacturer of infrastructure products and provides specialized services to the mining, construction, civil infrastructure, and solar industries.

The company’s Jennmar Services division provides plant maintenance, trucking, excavation, welding, steel erection, and concrete services to mining companies, construction contractors, and industrial plant operators.
FalconPoint acquired Jennmar in May 2024, and the acquisition of Rohrig is the eighth add-on acquisition it has completed under its ownership. The seven earlier add-ons were Michigan-based All Tech Engineering (April 2025); the Sweden-based rock bolt production facility of publicly traded SSAB, a Nordic and U.S.-based steel company (February 2025); the mine sealant product line of Wright-Mix’s Pyro-Chem division (December 2024); the West Virginia-based cement blending facility of Wright-Mix (August 2024); Quebec-based Dumotech Industrial Products (June 2024); Virginia-based G&R Gas Services (June 2024); and Perth-based Australian Steel & Wire (May 2024).
The history of Jennmar begins in 1922 when Frank and Mary Calandra founded Frank Calandra Inc. (FCI), a Cresson, Pennsylvania–based scrap metal collector located 80 miles east of Pittsburgh. The company evolved over the decades, expanding into mining equipment distribution and manufacturing. In 1965, FCI shifted its primary focus to the manufacturing of mine roof support systems. In 1972, Frank Calandra Jr. and John “Jack” Calandra, sons of the founders, consolidated the company’s various subsidiaries and sister companies under the name Jennmar.
Today, Pittsburgh-headquartered Jennmar is led by CEO Tony Calandra (the son of Frank Calandra Jr.) and EVP Michael Calandra (the son of Jack Calandra). The company operates more than twenty manufacturing facilities and multiple distribution warehouses across the United States, including locations in Alabama, Colorado, Georgia, Illinois, Kentucky, Michigan, Nevada, Pennsylvania, Texas, Utah, Virginia, and West Virginia, as well as internationally in Canada, Mexico, and Australia.
With the close of this transaction, Rohrig will now operate as part of the Jennmar Services division. “We are tremendously proud of the continued expansion of Jennmar Services, which extends Jennmar’s customer-centric approach through bespoke solutions designed to meet our customers where they are – all while growing the skilled manufacturing workforce,” said Tony Calandra. “Equipment maintenance and repair is essential to keeping our customers running, and we are thrilled to welcome Rohrig to the Jennmar family.”
