Erdemir
A major Turkish integrated steel producer focused on flat steel and related industrial materials.
Last updated August 21, 2026
Overview
Erdemir, formally Ereğli Demir ve Çelik Fabrikaları T.A.Ş., is one of Turkey’s principal steel producers and the flagship flat-steel company within the OYAK Mining and Metallurgy group. The business was established in 1960 at Karadeniz Ereğli on Turkey’s Black Sea coast, and began production in 1965. Its main industrial complex occupies approximately four square kilometres and includes integrated steelmaking, rolling, finishing, logistics and port infrastructure. The location gives Erdemir direct access to maritime routes used to bring in raw materials and distribute finished products. The company’s core output consists of flat steel products, including slabs and plates, hot-rolled sheet, cold-rolled sheet, galvanized products and tinplate. These materials serve demanding industrial applications in automotive manufacturing, household appliances, construction, machinery, energy and general fabrication. Erdemir’s position in the Turkish market has historically been particularly significant because it was the country’s only flat-steel producer until the entry of additional capacity in January 2009. Its product range and integrated production model have made it an important supplier for industries that require controlled thickness, surface quality, formability and consistent mechanical properties. Erdemir also operates the Port of Erdemir, which supports the import of iron ore, coal and other inputs and the export or domestic shipment of steel. The company is associated with the wider Turkish iron-and-steel industry through its ownership and industrial relationship with İsdemir, the integrated steel plant at İskenderun in Hatay Province. Erdemir has additionally been described as having involvement in coal activities in Turkey, reflecting the raw-material and energy requirements of integrated steel production. A major ownership turning point occurred on 4 October 2005, when OYAK acquired a 49.29 percent stake in Erdemir in a televised privatization auction. The transaction involved the purchase of a 46.12 percent holding from Turkey’s Privatization Administration and an obligation to acquire a further 3.17 percent stake from a Turkish bank. OYAK’s successful bid, reported at approximately US$2.77 billion, placed Erdemir at the centre of OYAK’s mining and metallurgy platform and shaped the company’s subsequent corporate identity. Erdemir reported crude-steel production capacity of approximately 8.5 million tonnes per year for 2020 in the referenced company profile. Its integrated blast-furnace-based production system provides scale and a broad product portfolio, but also creates a substantial environmental footprint compared with steelmaking based primarily on electric arc furnaces. Climate Trace estimated that the plant emitted almost five million tonnes of carbon dioxide in 2022. Erdemir has stated that it is working toward net-zero emissions, placing decarbonization, energy efficiency and lower-carbon production among the strategic issues facing the business. Today, Erdemir remains an active, publicly traded Turkish steel company. Its brand is associated primarily with industrial reliability, domestic supply security, large-scale integrated manufacturing and flat-steel specialization rather than consumer-facing products. The company is also recognized in Turkey for the engineering significance of its industrial complex, which has been included by the Turkish Chamber of Civil Engineers in a list of fifty notable civil-engineering achievements completed after the establishment of the Turkish Republic.
History
Erdemir was established in 1960 as a Turkish iron-and-steel enterprise intended to build domestic capacity in flat steel. Its main works were developed at Karadeniz Ereğli in Zonguldak Province, on the Black Sea coast, where access to a deep-water port could support the movement of ore, coal, finished steel and other bulk materials. Commercial production began in 1965. The company developed as an integrated steelworks, combining primary iron and steel production with rolling and finishing operations. This structure allowed Erdemir to produce a broad range of flat products rather than relying exclusively on imported semi-finished material. Its output came to include plates, hot-rolled and cold-rolled sheet, galvanized products and tinplate. The company’s location and scale made it a central element of Turkey’s industrialization and a key supplier to downstream manufacturers. For many years Erdemir was Turkey’s only producer of flat steel. That position changed in January 2009 when additional domestic flat-steel capacity entered the market. Even after competition increased, Erdemir retained strategic importance because of its established plant, port, production know-how, customer relationships and broad product portfolio. The company also became connected with the steel plant at İskenderun in southern Turkey, extending its relevance beyond the Black Sea facility. The most consequential ownership change in Erdemir’s modern history took place in 2005. On 4 October, the Turkish Armed Forces Pension Fund, OYAK, won a televised auction for a 49.29 percent stake. The acquisition consisted of a 46.12 percent interest held by Turkey’s Privatization Administration and a further 3.17 percent holding that OYAK was required to purchase from a Turkish bank. The reported transaction value was approximately US$2.77 billion. Following the transaction, Erdemir became a core asset of OYAK’s mining and metallurgy operations. Erdemir’s industrial model depends on large quantities of raw materials and energy. Its Port of Erdemir supports the movement of imported inputs and exported or domestically distributed products, while the company’s wider activities have included coal-related operations in Turkey. The integrated model provides production scale and control over steel quality, but it also produces more direct emissions than steelmaking based mainly on electric arc furnaces. Environmental performance has consequently become an important part of the company’s public profile. Climate Trace estimated almost five million tonnes of carbon dioxide emissions from the plant in 2022. Erdemir has said that it is moving toward net-zero emissions, although the transition presents substantial technical and capital challenges for an integrated producer. Decarbonization, energy efficiency, process modernization and the future use of lower-carbon technologies are therefore central long-term questions for the business. Erdemir’s principal market remains Turkey, with international trade supported by its coastal logistics infrastructure. Its products are used in automotive, appliances, construction, machinery and other industrial sectors. The company’s main plant has also been recognized domestically as a major engineering achievement: the Turkish Chamber of Civil Engineers included Erdemir among fifty notable civil-engineering projects realized after the founding of the Turkish Republic. Erdemir remains an active listed company and a leading component of OYAK’s Turkish steel platform.

Products and positioning
Large-scale, integrated Turkish steel producer supplying flat steel and value-added products to industrial customers.
Steel platesFlat steel
Erdemir produces steel plates for structural, engineering, construction and heavy industrial applications. Plates are supplied in grades and dimensions suited to downstream fabrication, where strength, weldability and dimensional consistency are important.
Hot-rolled sheetFlat steel
Hot-rolled sheet is one of Erdemir’s principal product families. It is used directly in construction, machinery and general fabrication and can also serve as an input for further processing into cold-rolled and coated products.
Cold-rolled sheetFlat steel
Cold-rolled sheet provides tighter thickness control and improved surface characteristics than basic hot-rolled material. It is suitable for applications requiring forming performance and appearance, including automotive components, appliances and other manufactured goods.
Galvanized steelCoated steel
Galvanized steel combines a flat-steel substrate with a zinc coating intended to improve resistance to corrosion. The product is relevant to construction, automotive, appliances and industrial uses where durability and surface protection are required.
TinplateCoated steel
Tinplate is a coated flat-steel product used where corrosion resistance, formability and a suitable surface are required. Erdemir identifies tinplate among the products manufactured within its broader flat-steel portfolio.
