What Steen-Hansen does

Steen-Hansen is a Norwegian specialty chemicals manufacturer headquartered in Nesttun (Bergen), Norway, focused on antifouling coatings and impregnation solutions for aquaculture fish nets. Founded in 1932 and operating with 11-50 employees, the company maintains a product portfolio organized around four categories: copper-based antifouling products, copper-free alternatives, biocide-free formulations positioned for environmentally sensitive operations, and an industrial paint line for adjacent coating applications. The company also operates NetCare, a wholly-owned service platform for aquaculture net maintenance, monitoring, and quality assurance, accessible via netcare.no.

The company's technology rests on proprietary antifouling formulations, including the use of tralopyril as an active ingredient, supported by an in-house R&D function that includes environmental modeling capabilities. Steen-Hansen sells exclusively on a B2B basis to fish farming operators through direct sales channels with quote-based pricing; no public price list is disclosed. The go-to-market is built around a product-catalog website, a knowledge base and blog targeting aquaculture industry topics (e.g., holistic pollution approaches, tralopyril use guidance), and direct phone and email contact for inquiries. No public financials, funding rounds, named customers, or leadership team bios are disclosed in the source material. Ownership structure is opaque: the company appears independently operated with no identified parent, PE backing, or public listing.

Broad incumbents

• Jotun: Norwegian-headquartered global marine and protective coatings major with extensive antifouling portfolio. Overlaps with Steen-Hansen on marine/ship-hull and offshore antifouling technology, but serves the much broader hull and offshore markets, not specialized fish-farm netting.
• Hempel: Danish-headquartered global marine coatings and paints company with a dedicated antifouling range (Hempaguard, Olympic). Similar product technology and customer touchpoint (marine fouling control), but operates at vastly greater scale across all marine segments and is not specialized to aquaculture nets.
• International Paint (AkzoNobel): AkzoNobel's marine coatings division supplies Intersleek, Intercept and other antifouling systems to global shipping, offshore and fish-farming customers. Closely overlapping product family and serves some aquaculture net-pen customers, but is part of a much larger diversified paints portfolio.
• Chugoku Marine Paints: One of the world's largest marine coatings companies, headquartered in Japan, with a full antifouling portfolio serving shipbuilding, offshore and some aquaculture applications. Overlaps Steen-Hansen on antifouling technology but at global ship-hull scale.
• Boero Group: Italian marine and yacht coatings group that also supplies fouling-control products. Comparable in chemistry and end-applications (boats, hulls, some aquaculture exposure), though anchored in the Mediterranean yacht/shipping market rather than Nordic salmon farming.

Direct peers

• CMP Coatings (Norwegian Coatings AS): Norwegian coatings manufacturer specializing in marine and antifouling coatings, including products for aquaculture. Matches Steen-Hansen most directly on geography, product chemistry (antifouling focus) and fish-farm end-market, making it the closest niche direct peer.

Emerging players

• I-Tech / Selektope: Swedish specialty company commercializing Selektope, a biocide-free antifouling active (medetomidine) added to coatings for marine and aquaculture use. Targets the same clean-antifouling trend as Steen-Hansen's Copper-free / Biocide-free lines, but supplies an ingredient rather than finished coatings.

Others

• AkzoNobel Industrial Coatings (non-marine): Parent group of International Paint and a global industrial coatings supplier. Adjacent because Steen-Hansen's Industrial Paint line competes in the same broader industrial paints space, even though fish-farm netting remains the focus.

Regional players

• Nor-Maitec / Aquaculture Net Service Providers: Norwegian aquaculture service firms offering net cleaning, inspection and maintenance directly to fish farms. Comparable to Steen-Hansen's NetCare service line on operational offering, though they service the physical net cleaning rather than chemical antifouling.
• Kansai Paint Marine: Japanese coatings major with a marine coatings business active in antifouling globally. Comparable in product chemistry but primarily focused on Asian and shipbuilding markets with limited Norwegian aquaculture presence.
