What Grede Holdings manufactures

Grede is an American iron foundry group that casts and machines safety-critical metal parts. Its core products are highly engineered ductile, gray, and specialty iron castings, produced across six foundries and finished in-house through precision machining and assembly. The parts fall into three markets. For automotive, Grede supplies chassis, suspension, and drivetrain components as an OEM and tier supplier. For commercial trucks, it casts engine and chassis components for heavy-duty applications. For industrial, agriculture, and heavy-equipment customers, it makes large axle housings and other drivetrain castings.

The company positions itself around design and engineering, not just pouring metal. It runs an in-house design function, offers casting simulation and validation, and markets a "Smart Foundry" program that applies Industry 4.0 sensing and automation across its plants. Machining is integrated with the foundries so customers can source finished, assembled components rather than raw castings.

Ownership and history

Grede's history runs to 1920, when William J. Grede bought the Liberty Foundry in Wauwatosa, Wisconsin, just west of Milwaukee, and renamed it Grede Foundries. That original site still operates today as the Liberty Foundry. Over the following century the business grew into one of the larger iron casters in North America.

The current ownership dates to 2019. Grede was carved out of American Axle & Manufacturing (AAM), which had held the iron casting operations, when funds managed by Gamut Capital Management, a New York private investment firm, agreed to acquire the business. Grede began operations as an independent company on December 16, 2019, and in 2025 marked five years under Gamut ownership. The legal entity is Grede Holdings LLC, headquartered at 20750 Civic Center Drive in Southfield, Michigan.

Leadership per the company's own materials: Reid Southby, Chief Executive Officer; Phillip Reise, Chief Financial Officer; Bob O'Neil, Chief Commercial Officer; and Anil Bilimoria, Chief Operating Officer. Southby joined as CEO in 2025 after operations leadership roles at Magna International and Autokiniton.

Footprint and recent portfolio changes

Grede reports roughly 3,000 team members across seven US facilities. Its foundries are in Biscoe, North Carolina; Wauwatosa and Reedsburg, Wisconsin; Meadville, Pennsylvania; New Castle, Indiana; and St. Cloud, Minnesota. Machining operations run at Biscoe, Menomonee Falls, Wisconsin, and Meadville. Corporate headquarters is in Southfield, Michigan.

The footprint has been actively managed under Gamut. In August 2021, Grede acquired the Advanced Cast Products heavy-truck and select industrial business of Neenah Enterprises in Meadville, Pennsylvania, adding about 250 employees and expanding its commercial vehicle capacity. In November 2025, moving the other direction, Grede sold its Browntown, Wisconsin and Iron Mountain, Michigan foundry assets to TRM Equity, a streamlining that concentrated the group on its remaining sites. Both moves are consistent with an owner shaping the portfolio around its strongest plants rather than a business in retreat.

Certifications and quality

Grede states that six of its locations are certified to IATF 16949, the automotive quality management standard: Biscoe, Menomonee Falls, New Castle, Reedsburg, St. Cloud, and Wauwatosa. IATF certification is the working requirement for supplying automotive OEM programs, and multi-site coverage is the sector norm for a Tier 1 caster. On sustainability, the company was recognized by the US Environmental Protection Agency as an ENERGY STAR Partner of the Year for energy management in 2016 and publishes a periodic sustainability report.

Known customers

Grede displays a roster of blue-chip customers on its own website. These are company-published relationships rather than program-level filings, so they read as reported, not independently documented.

The mix matches Grede's stated markets: passenger-vehicle OEMs, heavy-truck makers, and industrial and driveline suppliers.

Sourcing evidence

Grede's US import record is modest and reads like a domestic caster buying capital equipment, not a reseller importing finished goods. Bill-of-lading data shows about 123 sea shipments across two Grede entities, most recently in September 2026. The inbound goods trace to foundry-technology and machine-tool suppliers, including GKN Sinter Metals, BMD Foundry Technology, Boge Elastmetall, and DMG Mori. That is the import signature of a manufacturer equipping domestic plants, with the finished castings shipping to customers by truck and rail inside North America.

Coverage caveats: these are US ocean-freight records only. Truck and rail movements, which carry most of a domestic foundry's material, do not appear; some records name intermediaries rather than manufacturers; and manifest codes are noisy. Absence of a record is not evidence of absence.
