What Ulefos does

Ulefos is a Norwegian developer and manufacturer of infrastructure products for water supply (VA-teknikk), street goods (gategods), building and construction (bygg og anlegg), and outdoor environments (utemiljø). The company operates an in-house iron foundry at Ulefoss Jernværk that casts ductile and cast iron products using recycled scrap iron and renewable Norwegian hydropower, producing valves, manhole frames and covers (GULL, SØLV, BRONSE, ULTRA series), ductile pipes, drainage systems (Filcoten), and specialized solutions such as the Lod kjeftsluk for blue-green stormwater and the ReCirc 100% recyclable gasket. Technical differentiators include the Norwegian-developed Esco FLEX valve series (DN200–DN400), inspection-hole features integrated into manhole frames for quality control, and a pressure reduction valve with a patented seat design.

The business model is direct B2B sales to Norwegian municipalities, road authorities (Statens vegvesen), contractors (e.g., NCC), and engineering consultants (e.g., Norconsult) via a quote-based RFQ process. Pricing is project-specific, a standard catalog with NRF article numbers is published for SKUs, and customer advisors provide technical consultation. Distribution is single-country domestic (Norway), with products delivered to construction sites, municipal depots, and contractor locations. The company also operates the Ulefos Smart Water sub-brand for digital water-management solutions.

In January 2026, Ulefos Holding AS merged with Furnes Jernstøperi AS into a jointly owned company called CK Partners AS, anchored in the Cappelen and Kjær owner families, consolidating two domestic ductile iron foundries. The company employs 101–250 people and remains privately held, with no disclosed external funding or public listing.

• ACO Drain: European manufacturer of drainage channels and stormwater management systems. Comparable to Ulefos's Filcoten drainage and LOD stormwater product lines in building and infrastructure applications.
• Furnes Jernstøperi AS: Norwegian foundry producing cast iron manhole frames, covers, and gully products. Furnes is the most direct historical peer to Ulefos and has now been combined with Ulefos into CK Partners AS as of January 2026.
• Uponor: Finnish provider of pipe systems for water supply, heating, and infrastructure. Comparable to Ulefos in serving Nordic municipalities with water and building infrastructure products, though focused on plastic rather than iron systems.
• Hawle Austria GmbH: Austrian manufacturer of valves, hydrants, and fittings for water supply networks. Direct overlap with Ulefos's VA-teknikk valve portfolio and shared focus on European municipal water infrastructure customers.
• Wavin: Dutch manufacturer of plastic pipe systems and drainage solutions for building and infrastructure. Ulefos distributes Wavin-branded manhole products and overlaps in drainage and stormwater management offerings.

Broad incumbents

• McWane: US-based manufacturer of cast iron pipe, fittings, valves, and infrastructure products. Comparable in ferrous foundry capability and product overlap (ductile iron pipes, manhole products, valves) but operates at significantly larger scale.
• Saint-Gobain PAM: French global leader in cast iron pipe systems, manhole covers, and water infrastructure solutions. Overlaps with Ulefos in ductile iron pipes, manhole frames, and covers, but operates at much greater scale across multiple continents.

Emerging players
