Energy Steel

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.
