What McInnes Rolled Rings does

McInnes Rolled Rings is a privately held, Erie, Pennsylvania-based manufacturer of seamless rolled ring forgings, founded in 1992 and operating from a 100,000+ square foot facility at 1533 E 12th St. The company produces custom forged steel rings ranging from 4 inches to 144 inches (3,660 mm) in diameter in carbon, alloy, and stainless steel grades, plus forged discs up to 5,000 lbs and 70 inches outside diameter, with heat treatment as an integrated capability. Core manufacturing assets include three Wagner radial-axial ring rolling mills (KFR 630 for 4"-13.5", RAW 63/63 for 12"-72", RAW 160/160 for 25"-144") paired with Erie Press hydraulic preform presses of 1,200 and 3,500 tons, a 25,000 sq ft heat treat bay capable of processing 25-ton loads and quench-and-temper rings up to 144 inches in diameter (Can-Eng furnace technology with Dango & Dienthol material handling), and a Linsinger KSS 1010 circular sawing system added in 2025.

The ring rolling process yields tight tolerances with minimum material allowance and very little waste, and produces a radial grain flow that delivers superior structural integrity versus rings fabricated from steel plate (ASTM A36 or A516 Grade 70). The company is AS9100D / ISO 9001:2015 certified (TUV Rheinland), holds ABS Forging Approval for marine applications and EU 2014/68/EU Pressure Equipment Directive certification, and is an approved supplier to Rolls Royce North America and a Pratt & Whitney LCS-authorized supplier for US and Canada operations. Customer base is concentrated in Aerospace & Defense, Power Transmission, Industrial Equipment, Oil & Gas, and Food & Chemical Processing verticals.

The business model is direct B2B sales with quote-based custom pricing — customers request quotes via website, phone (1.800.569.1420), or email ([email protected]), with no public list pricing. Go-to-market combines a five-person inside sales team, trade show presence (notably Motion + Power Technology Expo, Booth #2922), earned media in trade publications (Gear Solutions, Stainless Steel World), email newsletter, and video/photo content on the website. Revenue is generated through one-time sales of custom forgings and ancillary heat treatment services. The company was acquired by Ellwood Group on March 31, 2025, joining a 100-year-old industrial platform with metal production and processing capabilities.
