What Energy Steel does
Energy Steel & Supply Co. (Energy Steel) is a U.S.-based, nuclear-industry-only manufacturer founded in 1982 and headquartered in Rochester Hills, Michigan. The company specializes in custom fabrication, precision machining, engineering services, material supply, and repair/refurbishment of safety-related and obsolete components for commercial nuclear power plants, nuclear waste handling programs, and nuclear fusion research projects. Its product portfolio spans bladder accumulators, heat exchangers, pumps and motors, valves, pressure vessels and tanks, structural supports, strainers, tensioning systems, and sluice gates — a range the company extends through more than ten strategic OEM partnerships and licensing agreements (including Parker Greer, INTEGRA BlackHawk, Hayward Tyler, Cameron/WKM, Servo Kinetics/Vickers, API Heat Transfer, and others) that grant it sole-source manufacturing rights for a wide catalog of obsolete nuclear parts.
The business operates under a B2B enterprise sales model with dedicated account management, a 24/7/365 Quick Response Team for outage and emergency needs, and quote-based project pricing — there are no publicly disclosed price tiers. Quality assurance is anchored by the full suite of ASME nuclear stamps (N, NPT, NS, NA, U, R, NR), NQA-1, 10CFR50 Appendix B, and 10CFR21 compliance, supported by 90+ degreed engineers using SolidWorks, Autodesk Inventor, COMPRESS, Mathcad, and Ansys for design, code calculations, and FEA/CFD/seismic analysis. Named customers include V.C. Summer Nuclear Station, Plant Vogtle, Nuclear Waste Partnership (WIPP), and the ITER fusion project in France.
Since 2019 Energy Steel has been a subsidiary of Hayward Tyler, itself a division of UK-listed Avingtrans PLC. In July 2020 it acquired the Parker Greer accumulator product line from Parker Hannifin; in June 2021 it relocated to its current Rochester Hills facility; in March 2023 it added the Vickers Series Pumps license via Servo Kinetics; and in January 2026 it announced a merger with Hayward Tyler Inc. that consolidates the two U.S. nuclear subsidiaries under a single brand and management structure while preserving the Energy Steel identity and location.

Energy Steel competitors and assessment
Company assessmentBroad incumbents
- Framatome: Major international nuclear reactor OEM and services provider with installed base across Europe, North America, and Asia. Comparable as a nuclear components and services supplier to commercial utilities; Energy Steel competes for adjacent service work and obsolescence replacement opportunities.
- BWX Technologies (BWXT): Major nuclear components manufacturer supplying naval nuclear reactors, commercial nuclear fuel, and specialty components for government and utility customers. Comparable in ASME Section III nuclear component manufacturing capabilities and customer overlap with U.S. nuclear utilities and DOE sites.
- Westinghouse Electric Company: Global nuclear reactor OEM and services firm with new-build (AP1000) and operating plant service lines. Overlaps with Energy Steel in supplying fabricated safety-related components and services to AP1000 sites (Vogtle, V.C. Summer), making it both a customer and a potential competitor in component supply.
- Curtiss-Wright Corporation: Diversified industrial and nuclear supplier providing engineered components, specialty valves, embedded computing, and naval nuclear fuel services. Overlaps with Energy Steel in nuclear-qualified valve, heat exchanger, and component manufacturing, but operates at much larger scale across defense, aerospace, and process industries.
- Mitsubishi Heavy Industries: Japanese industrial conglomerate with a major nuclear power systems division supplying reactors, components, and fuel cycle services globally. Comparable in nuclear-grade pressure vessel, pump, and component manufacturing, particularly relevant for fusion projects and ITER-adjacent work.
- SPX Technologies: Industrial manufacturer of cooling, heating, and detection products serving HVAC, detection, and power customers. Comparable to Energy Steel through its heat transfer and engineered solutions business, including nuclear-adjacent fabrication; Energy Steel's president previously led engineering at SPX Flow.
Regional players
- Doosan Enerbility: Korean manufacturer of major nuclear components (reactor vessels, steam generators, turbines) supplying domestic and select international projects. Comparable in nuclear ASME-coded heavy fabrication, though primarily serving Asian markets; represents competitive pressure for international expansion ambitions.
Direct peers
- Holtec International: Privately held supplier of nuclear fuel transport casks, spent fuel storage systems, and nuclear plant decommissioning equipment. Comparable in serving the U.S. nuclear waste and decommissioning value chain (overlap with Energy Steel's WIPP/TRUPACT-II work) and in ASME-coded fabrication for nuclear applications.
- Graham Corporation: Designs and manufactures heat transfer condensers, pressure vessels, and specialized fluid systems for the nuclear, defense, and process industries. Closely comparable in ASME-coded fabrication of heat exchangers, condensers, and reactor auxiliary components serving similar nuclear utility customers.
- Hayward Tyler: Direct parent and now merger partner; specializes in pumps, motors, and canned motor technology for nuclear and energy applications. Energy Steel's pump and motor fabrication overlaps with Hayward Tyler's U.S. operations, making it the most directly comparable peer in scope, certifications, and customer base.
