Top 10 Sheet Metal Fabrication Companies in the USA

Choosing a sheet metal fabrication partner in the United States is a high-stakes decision. The wrong choice costs more than money. It costs rework, missed deadlines, and sometimes a delayed product launch. I researched over 25 U.S.-based sheet metal fabrication companies for this guide. I cross-referenced data from The Fabricator’s FAB 40 list, SEC filings, industry market reports, and direct company disclosures. Then I scored each company on eight weighted criteria that matter to OEM engineers and procurement teams. The result is a ranked list of the 10 best sheet metal fabrication service providers in the USA — with transparent methodology, verifiable data, and honest trade-offs for each company. How I Selected These Companies I used a structured evaluation process with data from multiple independent sources. Data Sources The Fabricator FAB 40[^1] (2023–2025 editions) — the most recognized revenue-based ranking of U.S. contract fabricators SEC filings for publicly traded companies (MEC, Xometry) Industry reports from Research and Markets and Technavio B2B directories including IQS Directory, ThomasNet, and MFG.com Company websites, LinkedIn profiles, and press releases Customer reviews and engineering community feedback Scoring Framework Each company was scored 1–10 across eight dimensions.

Mayville Engineering Company (MEC) — Score: 9/10 Tier: Industry Leader Detail Info HQ Milwaukee, Wisconsin Founded 1945 Employees 2,200+ Revenue $582 million (2024, publicly reported) Facilities 20+ locations across the U.S. Certifications NYSE-listed (MEC), ITAR, ISO-compliant Website mecinc.com MEC has held the #1 spot on The Fabricator’s FAB 40 list[^3] for 15 consecutive years. That is the longest streak in the industry. No other contract fabricator in the U.S. has matched this consistency. As a publicly traded company, MEC offers fully verified financial data. Their 2024 annual revenue was $581.6 million. You can check this in their SEC filings[^4]. MEC is vertically integrated. They handle design, prototyping, fabrication, aluminum extrusion, coating, and assembly. This means fewer vendors in your supply chain. In 2025, MEC acquired Accu-Fab for $140.5 million. This moved them into the data center and critical power infrastructure markets. If your project involves power distribution enclosures or server hardware, MEC now competes directly in that space. Key strengths: 15 years as the #1 ranked U.S. contract fabricator (FAB 40) Full vertical integration from design to final assembly Publicly traded — transparent financials Serves six distinct end markets (commercial vehicles, construction, powersports, agriculture, military, data center) What to watch: Revenue declined slightly in 2024 (down 1.2%) due to softening demand Best suited for large OEM programs — not ideal for prototype-only projects Large organization — onboarding may take longer than with mid-sized shops 2. Cadrex Manufacturing Solutions — Score: 9/10 Tier: Industry Leader Detail Info HQ Romeoville, Illinois Founded 1976 (as CGI Automated Manufacturing) Employees 2,000+ Revenue ~$480 million (ranked #2 on FAB 40, 2023–2025) Facilities 22 locations in 9 U.S. states + Mexico (~1.6M sq ft) Certifications ISO 9001, AS9100D[^5], ITAR, BAE Systems Supplier of the Year Website cadrex.com Cadrex is the #2 contract fabricator in the U.S. by revenue. They have held that position on the FAB 40 since 2023. What makes Cadrex different is their geographic footprint. They operate 22 facilities across nine states and Mexico. That is the widest spread of any dedicated sheet metal fabricator in North America. Cadrex is backed by CORE Industrial Partners. Through more than 10 acquisitions, they have built a platform that spans sheet metal fabrication, precision machining, stamping, plastic injection molding, and full electromechanical assembly. Their strongest sector is data center and ICT hardware. They manufacture custom server rack components and enclosures for hyperscale cloud companies. If your project involves telecom, networking, or electrical infrastructure, Cadrex has purpose-built capabilities. Key strengths: 22-facility North American footprint — the broadest among dedicated sheet metal fabricators Strong data center and ICT specialization Mirrored U.S.–Mexico capabilities for cost optimization and scale flexibility BAE Systems Supplier of the Year — validated defense-sector performance What to watch: Privately held — revenue based on self-reporting, not independently audited Rapid acquisitions mean some legacy brands are still integrating Heavy ICT concentration could

Top 10 Best Sheet Metal Fabrication Companies in China (2026 Buyer’s Guide)

Sourcing sheet metal parts from China can cut your production costs by 30–50%. But picking the wrong fabrication partner can cost you far more — in scrapped parts, missed deadlines, and damaged client relationships. I’ve seen it happen. An OEM sends drawings to a factory with a great-looking website. Samples come back acceptable. Then the production run arrives with inconsistent tolerances, poor weld quality, and zero documentation. The factory stops responding. The buyer starts over — months behind schedule. The root of the problem is information. There are thousands of sheet metal fabricators in China. Most look identical online. Self-reported factory sizes. Unverifiable client lists. Expired certifications on flashy websites. Without reliable data, choosing a supplier feels like guessing. That’s why I built this guide. I researched over 25 candidates across company websites, B2B platforms, LinkedIn profiles, third-party databases, and industry publications. I scored each company on 8 weighted dimensions. Every entry includes honest buyer considerations — not just marketing highlights. If you’re an engineer, procurement manager, or OEM buyer sourcing custom sheet metal parts from China, this list gives you a real starting point. How These Companies Were Selected I evaluated candidates across 4+ source types: company websites, B2B platform listings (Alibaba, Made-in-China), third-party databases (Metoree, Ensun, Crunchbase), and industry media. A note on data quality: most company data in this space is self-reported. Factory sizes, client lists, and delivery rates are rarely audited by third parties. I’ve noted where independent verification is available. Treat all claims as a starting point for your own due diligence. Evaluation Criteria The global metal fabrication market reached over $20 billion in 2023[^1] and continues to grow. China holds the largest share. With that scale comes thousands of suppliers — and wide variation in quality. I used 8 dimensions with weighted scoring to evaluate each candidate: Dimension Weight What I Assessed Scale & Market Coverage 20% Factory size, workforce, export countries, production volume Product Line Completeness 15% Range of fabrication services and material capabilities Certifications & Compliance 15% ISO, IATF, AS9100, CE, RoHS certifications Client Reputation & Reviews 15% Named clients, verified partnerships, testimonials Industry Influence 10% Trade show presence, media coverage, industry recognition Supply Chain Capability 10% Lead times, MOQ flexibility, on-time delivery track record Digital Presence & Accessibility 10% Website quality, English support, quoting systems Geographic Relevance 5% Port access, industrial cluster advantages, logistics Each dimension scored 1–10. The weighted total gives a final score out of 10.
