What General Stamping & Metalworks does

General Stamping & Metalworks (GSM) is a third-generation, family-owned contract metal fabricator headquartered in South Bend, Indiana, founded in 1922 by H.P. Axelberg as General Sheet Metal Works. The company operates two ISO 9001:2015 certified manufacturing facilities (250,000 sq ft in South Bend built in 2018 and 68,000 sq ft in Tomah, Wisconsin established in 2006) totaling approximately 318,000 sq ft, and is ranked among Fabricator Magazine's Fab40 top 20 largest U.S. contract metal fabricators.

GSM offers a vertically integrated platform of 20 in-house capabilities — including progressive and transfer stamping (200-2,000 ton presses), 2D/3D and 5-axis laser cutting (14 lasers up to 24,000W plus TRUMPF TruMatic 5000 punch-laser), robotic and manual welding (9 six-axis robotic weld stations), CNC machining (precision turning to 0.0004 inch), tube fabrication (up to 10 inch diameter), roll forming, in-house tool and die build, Kohler Peak Performer precision leveling, kitting/assembly, and contract warehousing — deployed across eleven OEM verticals (automotive, agricultural and construction equipment, material handling, outdoor power equipment, recreational vehicles, solar and energy storage, data centers, military and defense, and steel cabinetry/enclosures). The company holds ITAR registration and CMMC Level 1 capability for defense work.

GSM generates revenue through project-based contract manufacturing services priced per part via quote, with multi-year supply agreements typical for OEM programs. The GTM motion is enterprise field sales supported by an inside sales team and direct quote intake through gsmwinc.com (accepting STEP, IGES, SolidWorks, Creo, DWG/DXF, and PDF drawings). Pricing is not publicly disclosed and quotes are customized based on part specifications, material, volume (with a free evaluation noted for programs approaching 20,000+ annual units), and a complimentary Design for Manufacturability review is offered. Named customers and program references span Toyota Material Handling (consecutive Premiere Supplier 2024-2025), Tesla, Ford, GM, Toyota, Chrysler, Mitsubishi, Geely, Forest River, Case IH, and Wheel Horse Products.
