Sterling Industrial

What Sterling Industrial does

Sterling Industrial, LLC is a multi-disciplined mechanical and industrial contractor headquartered in Evansville, Indiana, founded in 1982 as Sterling Boiler & Mechanical. The company self-performs general construction, boiler construction, building construction, industrial piping, electrical and instrumentation, mechanical equipment installation, heavy lifting and rigging, maintenance, 24/7 emergency service, and structural steel erection. A multi-craft union workforce spanning 12 building trades (Boilermakers, Pipefitters, Electricians, Ironworkers, Millwrights, and others) anchors the operating model. Sterling serves four primary market segments: Energy (power and energy infrastructure), Industrial (food & beverage, pharmaceutical, automotive, metals), Building Construction (healthcare, education, commercial), and Infrastructure (tunnel, water, energy distribution), delivering projects under design-build, CM/GC, EPC, and subcontract arrangements.

The company's revenue model rests on three streams: project-based construction (general construction, EPC, fabrication), long-term maintenance and managed-service agreements (e.g., CenterPoint Energy sole maintenance contractor since 2004), and 24/7 emergency service. Pricing is project-specific, set through competitive bidding or design-build negotiation; billing is typically multi-year on long-tail maintenance contracts and one-time on construction work. Enterprise clients include American Electric Power, CenterPoint Energy, Duke Energy, Toyota Motor Manufacturing Indiana, Alcoa Warrick, Kaiser Aluminum, Berry Global, Dairy Farmers of America, Tarrant Regional Water District, and various municipal and university customers. Technical differentiators include nearly 900 Welding Procedure Specifications qualified from over 400 Procedure Qualification Records across aluminum, stainless steels, Hastelloy, titanium, and exotic nickel alloys.

Sterling is wholly consolidated within Traylor Industrial Group (TIG), a holding company formed in 2020 under parent Traylor Construction Group, Inc. Traylor Bros. acquired 50% of Sterling in 2016, the company rebranded from Sterling Boiler & Mechanical to Sterling Industrial in 2019, and Industrial Contractors (founded 1964) merged into Sterling in 2022. Sister companies Triad Fabricators and Onyett Fabricators provide heavy plate, structural, CNC machining, and pressure vessel fabrication. Sterling has held ASME and NBBI Certificates of Authorization for power boilers, pressure vessels, and power piping for over 40 years, plus R Stamp Authorization for metallic repairs and a broad code credential stack (AISC, API, AWS, AWWA, NFPA, RCSC).
