Charles R. Goulding and Jacob Nolan analyze how additive manufacturing is helping Worthington Steel turn supply chain disruption and tariff risk into a strategic edge rather than a liability.
The American steel industry is undergoing a period of structural adjustment shaped by trade policy, persistent global supply chain volatility, and rising input, energy, and labor costs. Long characterized by high capital intensity and pronounced cyclicality, steelmaking and steel processing now operate in an environment where geopolitical risk, tariff regimes, and transportation disruptions have become enduring features rather than temporary shocks. These pressures have increased the strategic importance of operational efficiency, responsiveness, and domestic manufacturing resilience across the U.S. steel value chain.
Worthington Steel is a large U.S.-based steel processing company headquartered in Columbus, Ohio, employing roughly 6,000 people and operating an extensive network of processing facilities across North America. In fiscal year 2024, the company generated approximately US$4.6 billion in revenue, reflecting its scale as one of the largest downstream steel processors rather than a primary steel producer. Worthington Steel’s strategy centers on value-added processing, supply-chain integration, and operational efficiency to support automotive, construction, and industrial customers. The company has disclosed that it has engaged in discussions and conducted due diligence regarding a potential voluntary takeover of Klöckner & Co SE, though no binding agreement or acquisition price has been announced, and both parties have stated that a transaction is not assured.
Klöckner & Co SE
Klöckner & Co SE is a large global steel and metal distribution and processing company headquartered in Düsseldorf, Germany, employing roughly 6,500 people and operating around 120 service and warehouse locations across Europe and North America. In fiscal year 2024, the company generated approximately US$7.1 billion in sales, reflecting its scale as one of the world’s leading steel distributors rather than a primary producer. Klöckner’s strategy centers on value-added processing, logistics, and digitalized customer platforms that improve efficiency and responsiveness in a cyclical steel market. The company has also disclosed discussions with Worthington Steel regarding a potential voluntary takeover of Klöckner’s outstanding shares. While Worthington Steel has conducted due diligence, both parties have emphasized that negotiations may not ultimately result in a transaction.
Worthington Steel’s Recent Acquisitions
Worthington Steel’s acquisition-driven growth strategy further strengthens the strategic case for additive manufacturing. A foundational transaction was the 2021 acquisition of Tempel Steel, a global producer of precision electrical steel laminations used in electric motors, generators, and transformers. This deal significantly expanded Worthington Steel’s exposure to electrification-driven markets and added a network of highly engineered manufacturing facilities across North America, Asia, and Mexico. Building on that platform, Worthington Steel completed the acquisition of a controlling stake in the Italy-based Sitem Group in June 2025, further extending its European footprint and reinforcing its position in electric motor and industrial applications.
As Worthington Steel integrates these businesses across geographies and end markets, additive manufacturing becomes increasingly valuable as a scalable and standardized operational tool. Shared 3D printing capabilities enable faster integration of acquired facilities, accelerate the development and replication of tooling and maintenance solutions, and reduce reliance on external vendors. This supports operational consistency across automotive and motor lamination product lines while improving uptime, responsiveness, and cost control, which are critical advantages for a global steel processor serving high-precision and electrification focused markets.
The Worthington Steel 3D Printing Lab
Worthington Steel has institutionalized its use of additive manufacturing through a dedicated 3D printing lab that supports operations across its processing network. The lab focuses on rapid prototyping and production of operational components such as tooling, fixtures, guards, mounts, and replacement parts for legacy equipment. By centralizing design and validation while enabling deployment at the plant level, the lab shortens response times, reduces reliance on external suppliers, and improves consistency across facilities. As Worthington continues to expand through acquisitions, this internal additive manufacturing capability plays a growing role in standardizing processes, supporting integration, and maintaining high equipment uptime across an increasingly complex footprint.
Supply Chain Resilience and Tariff Mitigation
From a supply chain perspective, additive manufacturing reduces reliance on external suppliers, a critical advantage in a tariff-constrained and volatile trade environment. By localizing the production of non-core components, Worthington Steel gains greater control over costs, inventory levels, and production schedules. Internal 3D printing capabilities act as a buffer against transportation delays, supplier disruptions, and price volatility without requiring major capital investments in new steelmaking capacity.
The Research & Development Tax Credit
The now permanent Research & Development Tax Credit (R&D) Tax Credit is available for companies developing new or improved products, processes and/or software.
3D printing can help boost a company’s R&D Tax Credits. Wages for technical employees creating, testing and revising 3D printed prototypes can be included as a percentage of eligible time spent on the R&D Tax Credit. Similarly, when used as a method of improving a process, time spent integrating 3D printing hardware and software counts as an eligible activity. Lastly, when used for modeling and preproduction, the costs of filaments consumed during the development process may also be recovered.
Whether it is used for creating and testing prototypes or for final production, 3D printing is a great indicator that R&D credit-eligible activities are taking place. Companies implementing this technology at any point should consider taking advantage of R&D Tax Credits.
Conclusion
For Worthington Steel, additive manufacturing is not a disruptive alternative to traditional steel processing but a complementary capability that strengthens execution, resilience, and profitability. In an industry shaped by tariffs, rising costs, and supply chain uncertainty, 3D printing improves uptime, reduces operational risk, and enhances responsiveness across an expanding manufacturing footprint. As Worthington continues to grow through acquisitions like Klöckner and value-added processing, additive manufacturing is positioned to play a growing role in sustaining competitive advantage within the modern American steel industry.
