What Trinecke Zelezarny does

Třinecké železárny is the largest steel producer in the Czech Republic operating with domestic capital, founded in 1839 in Třinec and wholly owned by Moravia Steel a.s. since 1996. The company operates an integrated steelmaking process spanning blast furnace pig iron production, oxygen converter crude steel, continuous casting of semis, and multiple rolling mills producing SBQ bars, rails, wire rod, seamless tubes, bright steel, and flat/wide steel. Annual crude steel capacity is approximately 2.5 million tonnes, with 2,424 kt produced in 2025 and a cumulative output of nearly 190 million tonnes since founding. The group TŽ-MS employs 7,115 people on average adjusted headcount in 2025 and operates approximately 22 wholly-owned subsidiaries across the Czech Republic, Poland, and Hungary covering wire drawing, forging, springs, chains, refractory materials, energy supply, and scrap processing.

The company's commercial focus is B2B steel product sales to industrial customers across railway infrastructure, construction, automotive, oil & gas, energy (including wind power), and shipbuilding. Revenue is generated primarily through one-time sales of steel products priced with monthly scrap and alloy surcharges applied per product form and steel grade (W.Nr.), with additional revenue from processed slag aggregates, coke-chemical by-products, and energy services via Energetika Třinec. Distribution is conducted directly from the Třinec headquarters and through five European commercial representations (UK, Germany, Iberia, Slovenia, Italy) under the Moravia Steel brand, supported by dedicated sales managers per product category. Customers include Deutsche Bahn, ČD, PKP PLK, Infrabel in railway; IATF 16949-certified automotive buyers; API-certified oil & gas customers; and shipbuilders using ABS, DNV, Lloyd's Register, and Bureau Veritas approved grades.

The business model is anchored by 50+ product certifications (ISO 9001, IATF 16949, ISO 14001, ISO 45001, ISO 50001, API 5CT/5L, plus major maritime classification society approvals) that serve as entry barriers in target verticals. In 2025 revenue reached CZK 44,536 million (down from CZK 47,371 million in 2024) with net profit after tax of CZK 186 million, reflecting top-line pressure from European steel industry headwinds offset by cost-saving measures and stable production. The company is executing a multi-year decarbonization program called "Steel for Green" targeting 55% CO2 reduction by 2031 versus 1990 and carbon neutrality by 2050, with the Iron Ore Briquetting Line (started 2024), Blast Furnace 4 reconstruction (2025), gas-fired CHP plant (2026), and hydrogen-ready pipe development (2025) as the principal capital projects.
