What tranberg does

R. STAHL Tranberg AS is a Norwegian manufacturer of explosion-protected (Ex) equipment and specialist lighting systems for hazardous and harsh environments, headquartered at Strandsvingen 6, Stavanger, with manufacturing at the same site in Gausel. Founded in 1901 and operating as a wholly-owned subsidiary of the Frankfurt-listed R. STAHL AG (ticker SSH1), the company employs 59 people and is organized around three product verticals: Energy (Ex-certified junction and terminal boxes including the TEF 1058/1060/1061 and STAHL 8150 series, heat tracing systems, cable glands, enclosure heaters, and high-voltage solutions up to 11kV); Marine (BlueLine and Compact navigation lights, halogen/xenon/LED searchlights, floodlights, TEF 4800 and TEF 4900 Commander control systems, linear/technical lighting, and DNV-certified anti/de-icing winterization systems in which it holds the No. 1 position in the Offshore Supply Vessel market); and Aviation (CAP437-compliant Circle & H helideck lighting systems, control systems, floodlights, obstruction lights, perimeter lights, status lights, and windsocks).

The underlying technology relies on ATEX/IECEx-certified mechanical and electrical engineering rather than software or AI; product differentiation is driven by hazardous-area safety certification, durability (LED retrofits rated at 50,000 lifetime hours versus 750 for halogen), and integration capability through the Commander control platforms. Customers span Norwegian government entities (Norwegian Coast Guard, Port of Stavanger), shipyards (Tersan Shipyard), oil and gas EPC contractors, fishing and aquaculture operators, and offshore supply vessel owners.

The company monetizes through B2B enterprise sales on a quote-based, multi-year contract cadence with no public pricing, reaching customers via dedicated regional sales offices, the sister-company R. STAHL Scandinavia AS for Scandinavian coverage, and an international agent network (e.g., Solas Marine Services Group in the Middle East, Sonar in Iceland). Marketing leverages industry trade shows (Nor-Shipping, SMM Hamburg, ADIPEC, Nor-Fishing, Icelandic Fishing Expo), a growing LinkedIn presence (2,000+ followers, 400% growth over three years), and PR around heritage projects such as the 2025 Restauration bicentennial voyage sponsorship. Distribution is being restructured effective January 1, 2026, consolidating all Scandinavian sales under R. STAHL Scandinavia AS.

Broad incumbents

• R. STAHL AG: R. STAHL AG is Tranberg's listed parent and a global supplier of explosion-protected electrical equipment and hazardous-area systems. Its group-level Ex portfolio, international channels, and industrial customer base are directly relevant to Tranberg's hazardous-area products, although its scope is broader than Tranberg's marine and helideck lighting.
• Eaton: Eaton is a broad electrical-equipment incumbent with hazardous-location products and lighting and control capabilities. Its scale and broader portfolio make it a relevant incumbent comparator for Tranberg's Ex and lighting systems, although it is not a niche pure play.

Direct peers

• Pepperl+Fuchs: Pepperl+Fuchs supplies explosion protection, industrial sensors, and hazardous-area connectivity and electrical equipment. It serves similar industrial and process customers and is a direct comparator for Tranberg's Ex enclosures, cable-management, and hazardous-area solutions.
• BARTEC: BARTEC provides explosion-protected electrical equipment, control systems, and hazardous-area solutions for oil, gas, and process industries. It is a direct comparator for Tranberg's ATEX/IECEx-certified Ex equipment and energy portfolio.
• Raytec: Raytec manufactures LED lighting for hazardous and industrial environments, including certified luminaires. Its product category, safety requirements, and industrial customers closely match Tranberg's explosion-protected and harsh-environment lighting.
• Glamox: Glamox supplies technical lighting for marine, offshore, and industrial applications, with products designed for demanding environments. It is directly comparable to Tranberg's marine navigation, flood, and technical lighting portfolio.
• HELLA: HELLA, including Hella Marine, provides marine navigation, signaling, search, and work lighting for vessels. Its vessel-focused product portfolio and certification-driven customers are directly comparable to Tranberg's marine lighting business.
• Lopolight: Lopolight specializes in LED navigation and anchor lights for recreational and commercial marine vessels. It is a focused direct peer for Tranberg's BlueLine and compact LED navigation-light products.
• Perko: Perko manufactures marine lighting, navigation equipment, and related vessel hardware. It overlaps with Tranberg's navigation, searchlight, and technical-lighting products for shipowners and shipyards.
• Dialight: Dialight supplies industrial LED lighting, including high-reliability and hazardous-area applications. Its harsh-environment lighting and industrial customer base are comparable to Tranberg's specialized Ex and marine lighting.
