What Expom does

Expom S.A. is a Polish manufacturer of welded steel structures and pressure equipment, founded in 1952 and headquartered in Kurzętnik, Poland. The company is publicly listed on the Warsaw Stock Exchange under the ticker EXP and operates through a group structure that includes Konter, Werex, and the Expom Eco-Energy sub-brand. Expom produces certified steel fabrications for European industrial OEMs and engineering contractors across offshore, energy, industrial machinery, recycling, airport infrastructure, and agricultural sectors, with delivery capabilities extending internationally. Its customer base spans Austrian, German, Norwegian, and Polish industrial clients, managed through a dedicated Key Account Manager structure.

The company's production base spans approximately 20,000 m² across 13 production halls, equipped with 28 machines including 11 CNC stations and a JUARISTI CNC tool acquired in 2018, reported as the largest of its kind in northern Poland. Expom maintains a workforce of roughly 50 certified welders and over 247 qualified production workers, supported by multilingual project management in Polish, English, German, and Norwegian. The company holds more than 13 industry certifications — including DNV-GL, NORSOK, ASME IX, AWS D1.1, and FROSIO III — enabling it to bid for technically demanding projects in regulated sectors. A retractable-roof assembly hall and in-house non-destructive testing capacity support fully integrated production from raw material preparation through to final inspection.

Expom's business model centers on project-based B2B contracts, combining multi-year framework agreements with one-off engineered fabrications. Revenue is generated through long-cycle relationships with European industrial customers, with the Expom Group having completed more than 17,000 projects over 72 years of operation. Recent commercial development has emphasized vertical extension — most notably through the Eco-Energy sub-brand targeting biomass-fired and renewable energy installations — alongside a vocational training partnership that produces approximately 100 trained welders annually, indicating investments in both downstream product diversification and upstream talent pipeline development.

Direct peers

• Sif Group: Netherlands-based manufacturer of large steel foundations (monopiles, jackets) for offshore wind. Directly comparable to Expom in serving marine/offshore customers with large certified steel structures, though Sif is more specialized to wind foundations while Expom covers a broader scope (davits, cranes, platform components).
• Smulders: Belgian/Dutch fabricator of heavy steel constructions for offshore wind, oil & gas, and civil construction. Owned by Eiffage, Smulders produces foundations, substations, and complex steel structures — directly competing with Expom in the offshore/marine fabrication market with similar DNV/NORSOK-style certification requirements.
• Lamprell: UAE- and UK-headquartered provider of fabrication, engineering, and contracting services to the offshore oil & gas and renewable energy sectors. Like Expom, Lamprell produces large welded steel structures for offshore platforms and jack-up rigs under classification society supervision.

Regional players

• Mostostal Chojnice: Polish steel structure manufacturer producing welded constructions for bridges, industrial buildings, and offshore applications. Closest Polish domestic peer to Expom in terms of scope and customer overlap; both serve European industrial and infrastructure clients.
• Mostostal Puławy: Polish steel fabrication company specializing in large steel structures for power, chemical, and industrial clients. Comparable to Expom in scale, Polish-based operations, and industrial customer base, though with somewhat less marine/offshore orientation.
• Gustom SC: Polish steel construction manufacturer producing large welded steel structures for offshore, energy, and industrial sectors. Domestic peer with similar Polish labor base, customer profile, and certification scope to Expom's main operations.

Broad incumbents

• Bilfinger: Germany-headquartered global industrial services provider offering steel fabrication, maintenance, and engineering for process industries, energy, and offshore. A larger incumbent in overlapping steel-structure manufacturing services with broader geographic and end-market reach than Expom.
• Aker Solutions: Norwegian global engineering and fabrication company serving offshore oil & gas and offshore wind with large steel substructures, topsides, and mooring systems. Much larger scale than Expom but operates in the same marine/offshore fabrication space with similar certification regimes.

Emerging players

• CIMC Tianda (Offshore): Chinese offshore steel structure manufacturer serving wind and oil & gas markets with monopiles, jackets, and platform structures. Comparable in product category to Expom's marine segment, though at lower cost basis and with less European regulatory depth.
• Viessmann (Climate Solutions): German heat pump and HVAC solutions provider; a relevant peer to Expom Eco-Energy's heat pump offering rather than the steel fabrication core. Comparable in serving European residential/municipal energy transition demand.
