What İÇDAŞ does

İÇDAŞ ÇELİK ENERJİ TERSANE VE ULAŞIM SANAYİ A.Ş. is a privately held Turkish industrial conglomerate founded in 1969, headquartered in Istanbul with its principal operating complex in Biga, Çanakkale province. The company operates four integrated divisions — Steel (ÇELİK), Energy (ENERJİ), Shipyard (TERSANE), and Logistics (LOJİSTİK) — functioning as a single-site vertically integrated industrial platform. The steel division produces ribbed construction reinforcement bars, wire rod (filmaşin), and patented anti-seismic steel products, supported by in-house chemistry, mechanical, and metallurgical laboratories with TURKAK-accredited fatigue (Yorulma) testing capability — a technology İÇDAŞ was first to install among Turkish iron and steel producers. The energy division operates as three wholly-owned subsidiaries (İÇDAŞ Enerji, İÇDAŞ Elektrik, İÇDAŞ Topanel Elektrik) handling power generation and electricity operations, supplying the steel mill and potentially third-party customers. The Tersane shipyard produces harbour towage vessels and other maritime craft, and the logistics division operates Port I and Port II facilities for cargo handling and transport at the Biga site.

Revenue is generated through direct industrial sales of construction steel (to construction companies, contractors, and infrastructure developers), ship and vessel sales (to maritime and port operators), and energy production. Pricing is not publicly disclosed; sales are conducted through direct enterprise inquiries and supported by a broad certification portfolio — ISO 9001, ISO 14001, ISO 45001, ISO 50001, IATF 16949 (automotive), nuclear sector certification, TSE/TSEK, CARES UK, CE markings, and LEED compliance — together with product certifications accepted in 25+ export markets across Europe, Asia, and the Americas. İÇDAŞ employs 5,001–10,000 people, publishes annual sustainability reports, operates a public real-time emissions and meteorological monitoring portal, and discloses no revenue, funding, or ownership data; no private-equity, venture-capital, or public-listing signals are present. The company serves construction, maritime/port, and energy sector customers primarily in Turkey with material international export exposure.
