Zamet

What Zamet does

Zamet S.A. is a Poland-headquartered industrial company that historically designed and manufactured large-format steel structures and industrial machinery for heavy-industry customers worldwide. Its core offering has been custom-engineered steel constructions used in underwater mining, oil and gas extraction, infrastructure, metallurgy, transloading, and food processing — a portfolio of two product lines: large-sized steel structures and industrial machines and equipment. The company claims over 200 years of accumulated industry experience, delivery of steel structures to 120 of the largest underwater mining projects globally, a presence on all seven continents, and approximately 55,000 tons of steel structures produced from its plants in recent years.

The business model is B2B enterprise field sales: project-based, custom quotations for large-scale industrial customers rather than standardized catalog pricing. Zamet is publicly listed on the Warsaw Stock Exchange under the ticker ZMT, with a current share price of 0.9040 PLN as of 2 July 2026, and operates under TDJ S.A. as its parent holding company. Jacek Leonkiewicz (Managing Partner of TDJ S.A.) chairs the supervisory board, with Arkadiusz Pietreczek as President of the Management Board and Karolina Blacha-Cieślik as Vice-President. The company maintains a public-facing investor relations function with quarterly, semi-annual, and annual financial reports, corporate governance documents, and shareholder disclosures.

Critically, the company's own communications state that following the sale of key operating assets that historically formed the Zamet Group, Zamet S.A. is now in a transformation phase. The product, segment, and scale claims on the corporate website therefore describe a prior operating perimeter rather than the current business. The forward direction, new operating engine, and post-divestiture revenue base are not disclosed in the available data, making the entity's current commercial profile materially uncertain despite a well-articulated historical track record.

Direct peers

• Subsea 7: Subsea 7 designs, builds, and installs subsea structures and pipelines for offshore energy projects. It is a direct peer given Zamet's claim of participation in 120 of the largest underwater mining projects, which sit firmly in Subsea 7's traditional SURF and subsea construction project space.
• Saipem: Saipem is an Italian-based engineering and construction company with major offshore fabrication yards serving oil & gas, subsea, and industrial customers. Comparable to Zamet in serving large oil & gas and infrastructure EPC contracts involving heavy steel fabrication and large industrial equipment.
• TechnipFMC: TechnipFMC is a global leader in subsea, offshore, and surface engineering for the energy industry. Its subsea structures and SURF (subsea, umbilicals, risers and flowlines) business directly overlaps Zamet's underwater mining and offshore steel structure work for major oil & gas and mining customers.
• Aker Solutions: Aker Solutions is a Norway-based engineering and fabrication specialist for offshore oil & gas and renewables. It directly competes with Zamet's steel structure and industrial equipment work for offshore and subsea projects, especially in underwater mining/extraction contexts where Zamet claims inclusion in 120 of the largest projects globally.
• McDermott International: McDermott is a global provider of engineering, procurement, construction, and installation services for offshore oil & gas and infrastructure. Comparable to Zamet's steel-structure and heavy-industrial-equipment EPC focus and its cross-continental project delivery model.
• Heerema Fabrication Group: Heerema is a Dutch-based specialist in engineering, fabrication, and installation of large offshore structures for oil & gas and renewables. Comparable to Zamet in delivering custom, large-format steel structures to industrial offshore customers with similar engineering, fabrication, and logistics disciplines.

Broad incumbents

• Voestalpine: Voestalpine is an Austrian steel-based technology and capital goods group with a large industrial fabrication footprint. While broader in scope (automotive, railway, tool steel), its heavy steel structure, welding, and custom fabrication capability overlaps with Zamet's core industrial offering.
• Hyundai Heavy Industries: Hyundai Heavy Industries operates large-scale shipbuilding and offshore engineering fabrication yards, plus industrial machinery. Comparable to Zamet on dimensions of large-format steel fabrication and industrial equipment for oil & gas and mining customers across multiple continents.
• Larsen & Toubro: Larsen & Toubro is a major Indian engineering, construction, and fabrication conglomerate with global EPC reach across hydrocarbons, infrastructure, and heavy industrial equipment. Overlaps with Zamet's industrial equipment and large steel structure business in similar customer segments.
• BW Offshore: BW Offshore is a Norway-based provider of floating production services to the oil & gas industry. While more focused on FPSO operations, it is comparable to Zamet through its reliance on offshore engineering, fabrication, and relationships with industrial energy customers.
