Industry · Metals & Fabrication
Search 248,000+ verified suppliers across primary metals manufacturing (NAICS 331xxx) and fabricated metal products (NAICS 332xxx) — including 7,942 machine shops in NAICS 332710 alone. Cross-reference ISO 9001, AS9100, IATF 16949, NADCAP, and AWS D1.1 certifications against 318,000+ records from 13 government data sources. EPA and OSHA compliance data verify facility operations so your procurement team can qualify metal fabrication suppliers with confidence.
Procurement teams waste weeks searching ThomasNet listings and cold-calling machine shops with no way to verify certifications or capabilities. Mercata aggregates supplier data from SAM.gov, EPA facility registrations, OSHA inspection records, and certification registrar databases — then scores every metal fabrication supplier on a 0-100 Mercata Intelligence Score covering quality certifications, facility compliance, federal contract history, and market presence.
ISO 9001:2015, AS9100 Rev D (aerospace metals), IATF 16949 (automotive metals), and NADCAP special process accreditations verified against registrar databases in real time. AWS D1.1 structural welding and AISC steel fabrication certifications are cross-referenced with issuing body records — including scope, expiry, and renewal status. No more relying on self-reported profiles.
Search suppliers by precise NAICS codes: 331110 (Iron & Steel Mills), 331210 (Pipe & Tube), 331511 (Iron Foundries), 332312 (Structural Metal), 332510 (Hardware), 332710 (Machine Shops), 332722 (Bolts/Nuts/Screws), 332911 (Industrial Valves), and 332999 (Misc Fabricated Metal). Filter by CNC machining, metal stamping, die casting, forging, welding, sheet metal, surface treatment, heat treating, and powder coating capabilities.
Metal manufacturing facilities face rigorous environmental and safety requirements. Mercata cross-references EPA facility registrations and OSHA inspection records to verify that suppliers operate compliant facilities. Identify suppliers with clean compliance histories and flag those with outstanding violations — before they enter your supply chain.

Purpose-built tools for sourcing across the full spectrum of metals manufacturing — from precision CNC machining and investment casting to structural steel fabrication and custom metalwork.
Every metal fabrication supplier receives a Mercata Intelligence Score from 0 to 100 — combining certification status, EPA/OSHA compliance history, federal contract awards, facility data, and market demand signals. Filter and rank machine shops, foundries, and fabricators by score to shortlist qualified vendors in minutes instead of weeks of cold calls and RFI cycles.
Search by specific fabrication processes — CNC turning, 5-axis milling, MIG/TIG welding, laser cutting, waterjet cutting, press brake forming, investment casting, sand casting, die casting, forging, powder metallurgy, electroplating, anodizing, powder coating, and heat treating. Filter by material capability: carbon steel, stainless steel, aluminum, titanium, copper, brass, Inconel, and tool steel.
Track SBA-verified designations including 8(a), HUBZone, Service-Disabled Veteran-Owned Small Business (SDVOSB), Women-Owned Small Business (WOSB), and minority-owned certifications across all indexed metal fabrication suppliers. Generate exportable diversity spend reports for government subcontracting plan compliance and corporate supplier diversity programs.
If your machine shop, foundry, or metal fabrication facility appears in our database, you can claim your supplier profile to update capabilities, showcase certifications, and connect directly with procurement teams searching for your exact services. Claimed profiles rank higher in search results and receive RFQ notifications matched to your capabilities.
