CST Industries

What CST Industries does

CST Industries, Inc., founded in 1893 and headquartered in Kansas City, Missouri, is a private, Solace Capital Partners–backed manufacturer of engineered storage solutions for dry bulk and liquid materials. The company operates across a horizontal segmentation spanning agriculture, food & grain, plastics, mining & minerals, biomass, municipal water & wastewater, industrial liquids, oil & gas, data centers, and fire protection, selling into more than 125 countries through direct enterprise field sales, an Aquastore dealer network in North America, and regional sales/engineering offices across Asia, the Middle East, Africa, Europe, and Latin America.

The product architecture is built around five core brands—AQUASTORE and HARVESTORE (glass-fused-to-steel tanks with proprietary Vitrium TiO2 coating and EdgeCoat II six-sided encapsulation), TecTank (bolted epoxy, galvanized, and factory-welded configurations using the OptiBond Trico Bond process), OPTIDOME (flush batten aluminum geodesic domes), and CONSERVATEK (aluminum flat panel and steel covers). Manufacturing is performed in seven ISO 9001:2015-certified facilities in the US, Europe, and Asia, with the Parsons, Kansas plant holding the world's first API-12B monogram certification. Products are certified to AWWA D103, NFPA 22, FM 4020/4021, ANSI/NSF 61, API 650, and UL 142 standards, supporting regulatory-driven procurement in municipal and oil & gas segments.

The business model is primarily project-based capital equipment sales (one-time) supplemented by a recurring Master Service Agreement stream covering visual inspection, ultrasonic thickness testing, ROV underwater inspection, combustible dust hazard services (delivered via partnership with Fike and Conversion Technology Inc.), tank repair and modification, and OEM parts. Pricing is custom quote-based with no public list, and 2024 inorganic growth includes the acquisition of Ostsee Tank Solutions GmbH to expand European aluminum dome capacity and entry into the data center cooling-water vertical.
