What Stainless Technologies does

Stainless Technologies is a U.S. stainless steel process equipment fabricator founded in 1986 and headquartered in Menomonie, Wisconsin, serving food, dairy, beverage, and nutraceutical manufacturers. The company designs, fabricates, and installs complete turn-key process systems — from individual components such as membrane filtration, evaporators, dryers, pasteurization skids, CIP systems, storage tanks, custom decks, and valve clusters, through to multi-million-dollar grass-roots plant builds — using an in-house fabrication facility equipped with waterjet, blast booth, T-drill, press brake, shear, tank roller, and orbital welders. It also serves as a master distributor of 304 and 316L sanitary fittings and valves, maintaining over $1.5M of inventory with 24-hour shipping. Core engineering tools are SolidWorks and AutoCAD for mechanical design, with PLC programming, HMI development, and control panel design handled in-house for automation and controls work.

The company's go-to-market is direct enterprise sales to operational buyers at food and dairy manufacturing plants, with no channel partners, resellers, or third-party integrators. Pricing is quote-based on custom project scope and is not publicly disclosed. Revenue is generated across six streams: one-time process equipment sales, turn-key installation services, equipment leasing, own-and-operate contracts, aftermarket parts and fittings distribution, and mechanical design/engineering services. Field installation is delivered by 40-man service crews for projects running up to four weeks on customer sites. The business operates from four U.S. locations — Menomonie WI (HQ), Woodbury MN, Darlington WI (manufacturing), and Visalia CA — and references more than 1,000 completed projects across its history.

Ownership is founder-led; the current owner previously founded and sold Protient Inc., a multi-plant whey, soy, and milk protein manufacturer, before acquiring Stainless Technologies to serve that customer base. The company maintains ISNetworld qualification and uses standard industrial automation rather than AI/ML tooling. It is privately held with no disclosed institutional investors, board composition, or secondary ownership changes in the source material.

Core offering

Stainless Technologies engineers, fabricates, and installs stainless steel process equipment and complete turn-key process systems for food, dairy, beverage, and nutraceutical manufacturers. Offerings span custom process systems, individual process equipment (membrane filtration, CIP, HTST/UHT, evaporators, dryers, mixers, pasteurizers, heat exchangers, storage tanks), sanitary fittings and valves, stainless enclosures, mechanical design, automation and controls, project management, on-site field installation with own crews, and equipment leasing or own-and-operate contracts.

Product overview

Stainless Technologies is a stainless steel fabrication company offering a comprehensive portfolio of process equipment and services for the food, dairy, and nutraceutical industries since 1986. The core offering centers on Complete Process Systems — full turn-key installations ranging from prototype equipment to multi-million dollar grass-roots plant builds. These systems integrate multiple product lines: custom-built tanks, decks, hoppers, and valve clusters as fabricated components; stainless enclosures for housing electrical and pneumatic equipment; and an extensive inventory of 304/316L sanitary fittings and valves. Supporting these manufactured products are engineering service modules — Mechanical Design (SolidWorks/AutoCAD-based), Automation and Controls (PLC programming, HMI, control panels), Project Management (concept-to-completion), and Field Installation (up to 40-man crews for multi-week site projects). The company also operates a controlled in-house fabrication facility with waterjet, orbital welding, and other precision equipment, allowing it to produce a large portion of each project internally. All offerings are delivered through offices in Menomonie WI, St. Paul MN, Darlington WI, and Visalia CA.
