Greno Industries delivers precision‑machined components for turbines, generators, and rotating equipment across the power generation industry. We manufacture high‑performance parts for steam turbines, gas turbines, aeroderivative engines, mobile power units, and more.
For over 60 years, OEMs, utilities, and service providers have relied on Greno for tight‑tolerance CNC machining, advanced alloy expertise, and dependable U.S. manufacturing. Based in Scotia, NY, we are AS9100:2016 and ISO9001:2015 certified.
Power generation applications often need oversized components and complex designs that standard machine shops can’t handle. Greno’s in-house capabilities address these challenges:
Large Diameter Turning: We routinely machine heavy-duty, oversized studs and heavy hex nuts required for turbine casings and high-pressure flanges.
In-House Gun Drilling: Critical for power generation, our deep-hole gun drilling allows us to manufacture hollow turbine studs and fasteners with integrated center-bored heater holes, enabling precise ultrasonic elongation measurements during tensioning.
Tight Tolerance Threading: To ensure uniform load distribution and eliminate cross-threading risks during high-torque field installations, we achieve thread profiles and dimensional tolerances as tight as ±0.0001”.
Selecting the correct material grade is vital to combat creep rupture, oxidation, and fatigue over decades of service. Greno stocks and machines premium, certified alloys tailored for power generation environments, including:
These materials are selected for strength, oxidation resistance, thermal stability, and fatigue performance. Our machinists understand how to work with these alloys to achieve precise, repeatable results.
Greno’s power generation solutions are built on advanced CNC machining capabilities, including:
Our CNC equipmentallows us to produce intricate geometries, maintain tight tolerances, and deliver consistent quality across production runs. We collaborate closely with engineering teams to optimize manufacturability, reduce waste, and improve cost efficiency.
We also provide precision manufacturing services that include:
Greno’s ability to combine precision machining with in-house welding and hardfacing allows us to produce complex components with dimensional accuracy and structural integrity.
Our industrial assembly helps you to reduce internal handling, and our kitting and packaging services reduce your assembly time while eliminating time-consuming part searches.
Power generation components must meet strict industry standards. As part of our commitment to quality assurance, Greno maintains:
Every part is inspected to ensure it meets or exceeds customer specifications. Our quality management system supports safe, reliable operation in mission‑critical environments, and we offer both non-destructive testing and precision measurement eliminating time-consuming searches for individual parts.
Steam turbines rely on precise geometry and robust materials to maintain efficiency and withstand thermal cycling.
Greno machines steam turbine parts such as:
These components are produced using advanced CNC turning, milling, and large‑format machining centers capable of holding tight tolerances across complex geometries. Our experience with high‑temperature alloys ensures durability in demanding steam environments.
Gas turbines require components that can endure extreme heat, rapid temperature changes, and high rotational speeds.
Greno machines gas turbine parts such as:
We routinely machine nickel‑based superalloys like Inconel, Hastelloy, and other heat‑resistant materials for gas turbine performance.

Mobile power generation units are used in oil and gas, emergency response, and remote operations.
Greno machines components such as:
These precision machined components are engineered to withstand vibration, transport shock, and variable environmental conditions.
Generators and rotating equipment depend on precision alignment, balanced assemblies, and durable materials.
That’s why Greno machines:
Every machined metal part is inspected to ensure dimensional accuracy, proper fit, and long‑term reliability. Our machining services support both new production and refurbishment programs for OEMs, utilities, and service providers.
Hydroelectric facilities across the U.S. Northeast and eastern Canada trust Greno for precision machined parts.
The parts we machine include:
Bring your critical hydroelectric components to a manufacturer with the scale, certifications, and regional footprint to deliver on time and on budget.
Power generation facilities need custom fasteners that can withstand tough environments. From continuous thermal cycling to extreme high-pressure steam and constant structural vibration, standard fasteners can’t prevent joint relaxation or stress corrosion cracking.
Greno Industries manufactures high-precision, heavy-duty fastening solutions that maintain joint integrity and prevent catastrophic failure in critical power infrastructure. At our manufacturing facility in Scotia, New York, we machine power generation fasteners for:
We support both original equipment manufacturers (OEMs) and maintenance, repair, and overhaul (MRO) field service teams during planned outages and urgent turnarounds.
From prototype development to full‑scale production, Greno Industries delivers power generation solutions that meet the highest standards of performance and reliability.
Our precision‑machined components support utilities, OEMs, and service providers across the power generation industry. For durable, high‑accuracy components for turbines, generators, or mobile power systems, Greno is ready to support your next project.
