What SSM Industries does

SSM Industries, Inc. (SSMI) is a privately held, family-influenced full-service mechanical contractor headquartered in Pittsburgh, Pennsylvania, with origins tracing to Schneider Sheet Metal (founded 1961, reorganized as SSMI in 1988) and entry into the nuclear industry in the late 1960s. The company designs, fabricates, installs, and services HVAC, sheet metal, plumbing, refrigeration, and process piping systems across five operating divisions (Mechanical, Sheet Metal, Industrial, Plumbing, and Power & Nuclear), supported by a dedicated Mechanical Service Department and a wholly-owned spiral duct manufacturing subsidiary, Midstates Spiral. SSMI claims to be the largest Nuclear Safety Related HVAC designer/fabricator/supplier/installer in the United States, supported by 40+ years of nuclear experience, NUPIC pre-qualification, and 28+ active certifications spanning ASME, AWS, NFPA, NQA-1, and ASSE programs.

SSMI serves a diverse end-market mix including healthcare (e.g., UPMC, CHOP, Penn Medicine, AHN), education (Carnegie Mellon, Penn State, Pitt, UPenn), industrial (U.S. Steel, ALCOA, ATI, Bayer, P&G), nuclear and conventional power (Southern Nuclear, Westinghouse, Bechtel, Constellation, TVA, Xcel), government (DOE, FBI, VA, City of Pittsburgh), sports venues (Pittsburgh Steelers/Pirates, Philadelphia Phillies), and financial institutions (BNY Mellon, PNC). The largest single disclosed engagement is the HVAC subcontractor scope on the Vogtle 3 & 4 nuclear new-build project valued at $210M+.

SSMI generates revenue through project-based mechanical contracting (one-time, multi-year contracts for new construction and installation) and recurring service & maintenance agreements (annual preventative maintenance contracts and 24/7 emergency service). Distribution is exclusively direct via enterprise field sales, with four regional offices in Pittsburgh, Wilmington DE, Carlisle PA, and Latrobe PA serving Pennsylvania, Delaware, New Jersey, and Maryland, plus project-based deployments to larger nuclear sites (Georgia, South Carolina) and select international nuclear engagements (China, Korea). Pricing is quote-based and project-specific with no public pricing.
