What AK Industries does

AK Industries, Inc. is a privately held U.S. manufacturer, founded in 1981 by brothers John and Butch Sabo in Plymouth, Indiana, that produces fiberglass and polyethylene products for the wastewater industry. The company operates four divisions — Fiberglass, Poly, Septic, and Custom Molding — across more than 400,000 square feet of manufacturing space. Its core product lines include high-capacity fiberglass lift stations and basins (18"–120" diameter) for municipalities, rotationally molded polyethylene sump pits, sewage basins, and septic tanks with lifetime warranties, horizontal leg tanks for potable water and chemicals, and specialty triple-garage basins for volatile-liquid separation. The technical platform combines rotational and (since 2020) injection molding, anti-floatation collar engineering, and specialty resin formulations for high-temperature and chemical-exposure applications. Products carry IAPMO and CSA approvals in nearly every U.S. state and meet ASTM D3753-99 for FRP lift stations and FDA 21 CFR 177.1520 for potable-water contact.

The business model is a sales-led, quote-based direct-to-customer operation with division-specific phone/fax lines, dedicated Request-for-Quote forms, and a content-rich website with catalogs, installation guides, and a buoyancy calculator. Customer segments are municipalities (centralized wastewater management), residential/homeowners (decentralized septic and sump systems), and custom/project-based customers requiring specialty molding. Distribution is single-country domestic through direct sales, supplemented by stocking locations to improve lead times. Revenue streams come from one-time sales of fiberglass products, polyethylene products, and custom molding services — pricing is not publicly disclosed. The company completed the acquisition of SludgeHammer Group, Ltd. (2024) to extend into broader wastewater treatment solutions, invested in a new rotational molding machine and energy-efficiency infrastructure (88% lighting energy reduction, $42,000+ annual savings), and added injection molding capability in 2020 to support new SKUs and capacity growth.
