Foundation Steel has been named to the 2026 Inc. 5000, marking the company's second appearance on Inc.'s annual ranking of the fastest-growing privately held companies in the United States. The recognition follows 52 percent revenue growth from 2022 through 2025 and reflects continued expansion by the woman-owned structural steel contractor.
Foundation Steel first earned a place on the Inc. 5000 in 2020. Returning to the list in 2026 represents another national recognition for a company that has continued to expand its workforce, project capabilities, and geographic reach while operating in a labor- and safety-intensive segment of the construction industry.
"Every point of growth behind this recognition was built by our entire team—from the estimators and project managers who set us up for success, to our office staff, our safety personnel, and the ironworkers out in the field," said Charlotte Dymarkowski, Owner and President of Foundation Steel. "You cannot shortcut reinforcing and structural steel. You cannot scale it faster than you can plan it, manage it, and develop people and teams who erect it safely. Being recognized nationally for the second time tells me that our entire organization has built something that holds under load."
Founded in 2008, Foundation Steel has grown from its Swanton, Ohio headquarters into a multi-location operation with additional offices in Detroit, Columbus, Dayton, and Cincinnati. The company has completed more than 6,000 projects and has a workforce of more than 325 professional craftsmen supporting commercial, industrial, institutional, and infrastructure construction.
Foundation Steel provides structural steel erection, concrete reinforcing and post-tensioning, pre-engineered metal building systems, overhead crane installation and maintenance, rigging and machinery moving, industrial maintenance, and design assist consulting. Its project experience includes healthcare facilities, automotive facilities, schools, sports venues, warehouses, bridges, and heavy industrial structures.
The company's growth has taken place in an industry where additional project volume requires corresponding increases in skilled field labor, supervision, equipment, planning, and safety resources. Unlike businesses that can add capacity primarily through technology or inventory, structural steel contractors depend on qualified crews and field coordination to support each additional project.
That operating environment makes sustained growth closely tied to workforce development and project execution. Foundation Steel's field workforce includes union-affiliated, journeyman-certified ironworkers, and the company is certified by the American Institute of Steel Construction as an AISC Certified Erector.
The 2026 Inc. 5000 recognition also adds to a series of industry milestones for Foundation Steel. The company received a 2022 Metal Building of the Year award from the Metal Building Contractors and Erectors Association and was included in the 2021 Metal Construction News Metal Construction Hall of Fame.
For Foundation Steel, the second Inc. 5000 appearance reflects growth across both the business and the field organization required to support that growth. The company continues to work with general contractors, construction managers, manufacturers, and facility owners on projects that require coordinated structural steel, reinforcing, rigging, crane, and related construction capabilities.
The Inc. 5000 evaluates privately held U.S. companies based on percentage revenue growth over a three-year period. For the 2026 list, growth was measured from 2022 through 2025. Qualifying companies must also meet Inc.'s requirements regarding operating history, ownership, independence, and annual revenue.
Foundation Steel's 52 percent growth during the measurement period reflects continued expansion more than 15 years after the company's founding. That growth has been supported by a workforce of skilled tradespeople and project teams operating across multiple markets and construction sectors.
The company's project history now includes more than 6,000 completed projects, while its service capabilities extend beyond structural steel erection into reinforcing steel, post-tensioning, pre-engineered metal buildings, crane services, machinery moving, rigging, and design assist work. This range allows Foundation Steel to participate in multiple phases and disciplines within commercial and industrial construction.
Inc. will recognize members of the 2026 Inc. 5000 during the Inc. 5000 Conference & Gala, scheduled for October 14–16, 2026, at the Omni Dallas Hotel in Dallas.
Foundation Steel's return to the Inc. 5000 provides another national milestone for the company as it continues building its workforce, project portfolio, and construction capabilities.
