Hallsten

What Hallsten does

Founded in 1966 by John Hallsten, Hallsten Corporation is a privately held specialty fabricator headquartered in North Highlands, California, that designs and manufactures structural aluminum products. Its offering spans three verticals: Environmental (aluminum basin covers for wastewater odor control and the Biofloor biofiltration support system), Marine (Lite-Span gangways, public and private docks, Crew-Pro reconfigurable docks, boarding systems, and log booms), and Industrial (ADA ramps, pedestrian bridges, OSHA-compliant access structures, architectural elements, and a patented fencing piste). The product platform is built on a patented, weldless interlocking aluminum component system anchored by five U.S. patents covering the deck structure, tank cover, gear-hinged access panel, Airbeam aeration cover, and Biofloor modules. Engineering is led by PE-licensed professionals and uses specialized adhesives plus non-threaded mechanical connectors in lieu of welding for improved fatigue resistance in marine and dynamic-load environments.

The customer base is concentrated in municipal water and wastewater authorities, federal agencies including the U.S. Navy and the National Parks Service, universities, private marinas, and commercial/industrial buyers. Projects are custom-engineered per site and range from small tank covers to 82,000 sq ft clarifier enclosures and multi-base military gangway programs. All work is quote-based with no public pricing; revenue is generated through one-time project sales plus replacement parts for the installed base.

Go-to-market is primarily indirect across North America via 18+ independent regional sales representative firms covering the U.S., Canada, and Hawaii, with direct sales by Hallsten Corp. in four interior U.S. territories (Indiana, Louisiana, Southern Mississippi, West Virginia). The company remains family-controlled under President Jeff Hallsten, PE. No external funding rounds, M&A activity, public-company disclosures, or revenue figures were identified in the available sources.

Core offering

Hallsten Corporation designs, engineers, and fabricates custom structural aluminum products — including aluminum tank covers, gangways, docks, pedestrian bridges, ADA ramps, access structures, and biofiltration support systems — for environmental (wastewater odor control), marine, and industrial applications. Products are built on a proprietary weldless interlocking aluminum component system protected by five US patents and are sold as custom-engineered, quote-based projects through a regional sales-representative network. The company also supplies replacement parts and supports design-build projects with PE-licensed engineering staff.

Product overview

Hallsten Corporation is a manufacturer of structural aluminum products organized into three product lines: Environmental (Aluminum Covers, BioFloor for odor and VOC control), Marine (Lite-Span Gangways, Public/Private/Crew-Pro Docks, Boarding Systems, Log Booms), and Industrial (ADA Ramp Systems, Pedestrian Bridges, Access Structures, Architectural Elements, Fencing Floor). The products are based on a proprietary interlocking aluminum component system developed since 1966, featuring weldless design, marine-grade corrosion resistance, and modular construction for customized configurations across wastewater treatment, marine access, and industrial applications.

Others

• Bilco Company: Bilco Company manufactures specialty access hatches, doors, and roof products used across commercial, industrial, and infrastructure settings. Its access hatches are adjacent to Hallsten's gear-hinged access panels and serve similar municipal and industrial facility customers.

Direct peers

• SF Marina Systems: SF Marina Systems builds floating concrete and aluminum dock systems, breakwaters, and marina accessories globally. It competes with Hallsten in the public/military marine infrastructure segment, particularly for marinas and waterfront installations.
• Temcor: Temcor designs and fabricates aluminum dome and flat covers for wastewater and industrial tank applications. It is the closest direct competitor to Hallsten's environmental aluminum cover line, serving the same municipal and industrial odor-control use cases.
• Bellingham Marine: Bellingham Marine designs, manufactures, and installs floating dock systems, marinas, and waterfront structures, frequently in aluminum. It competes directly with Hallsten's Marine product line for marina, public dock, and gangway specifications across North America.
• Wahoo Docks: Wahoo Docks manufactures aluminum floating dock systems and gangways for residential, commercial, and government waterfront projects. It overlaps Hallsten's Lite-Span gangway and Crew-Pro dock offerings with a comparable product approach.
• Meeco Sullivan: Meeco Sullivan produces aluminum and concrete floating dock systems, gangways, and marina infrastructure. It is a direct peer in the marine/marina vertical, serving comparable municipal, residential, and commercial waterfront customers.

Broad incumbents

• Oldcastle Infrastructure: Oldcastle Infrastructure (CRH) supplies a broad portfolio of engineered infrastructure products including drainage, stormwater, and structural components. It is an incumbent that overlaps with Hallsten's industrial access and structural offerings as part of a wider building-products catalog.
• CST Industries: CST Industries manufactures bolted and welded storage tanks along with aluminum covers (including Temcor) for water and wastewater applications. It is a much larger incumbent that overlaps Hallsten's cover and tank-adjacent business with a broader product portfolio.
• Contech Engineered Solutions: Contech Engineered Solutions provides engineered metal products for stormwater, wastewater, and civil infrastructure. It overlaps with Hallsten's environmental cover and access-structure work via a broader site solutions portfolio aimed at engineers and municipalities.

Emerging players

• FRP Manufacturing (a Coatings Inc. company): FRP Manufacturing produces fiberglass reinforced plastic covers, baffles, and odor-control structures for wastewater. It competes in Hallsten's environmental use cases with an alternative composite material approach rather than aluminum.
