Steel Tank and Fabricating

What Steel Tank and Fabricating does

Steel Tank and Fabricating Corporation (STAFCO) is a U.S. manufacturer of aboveground steel storage tanks (ASTs), founded in 1952 by William E. Kennedy, Jr. and operating from a single facility in Columbia City, Indiana. The company fabricates carbon-steel and stainless-steel tanks in capacities ranging from roughly 150 gallons to 50,000+ gallons, with maximum dimensions of 13 feet in diameter by 50 feet long and plate thickness up to one-half inch. Configurations include single-wall, double-wall (interstitial-monitored), and fire-rated (UL-2085 Fireguard, STI Flameshield) units, with custom engineering supported by licensed Professional Engineers for stamped drawings. STAFCO holds UL-142, UL-2085, STI F921, and EPA certifications and is a member of STI/SPFA and PEI, providing a regulatory pathway into fuel, chemical, and life-safety applications.

STAFCO serves a diversified vertical mix that has expanded beyond its petroleum origin to include agriculture, construction, fleet operations, municipalities, hospitals and healthcare, data centers, and general industrial / chemical processing. Products are specified by end users such as farms, trucking companies, contractors, fuel terminals, hospitals, and AI/colo data center campuses requiring extended generator runtime. The firm also sells tank accessories (pumps, vents, gauges, overfill prevention, spill containers) with factory installation available, and distributes certain Morrison Bros. products through its storefront.

Revenue is generated through a sales-led, direct-to-customer model built on a quote-based system for engineered tanks and an online storefront for smaller units and accessories. Pricing is unit-based with freight calculated separately after purchase; custom tanks are non-returnable and standard tanks carry a 20% restocking fee. Distribution is direct, with nationwide freight shipping from the Indiana headquarters. The company is privately held under fifth-generation Kennedy family leadership (Bill Kennedy, President since 2020), with no disclosed funding rounds, parent company, or outside institutional ownership.
