What ÇAĞ ÇELİK does

Çağ Çelik Demir ve Çelik Endüstri A.Ş. is a Turkish long-steel products manufacturer founded in 1978 in Karabük and headquartered in Sancaktepe, Istanbul. The company operates a vertically integrated production complex on a 50,000 m² closed manufacturing site in Karabük combining hot rolling, cold drawing, profile forming, wire drawing, and nail production. It offers 600+ product varieties across five categories — hot rolled sections (equal angle, flat, round, square, hexagonal bars), cold drawn products (hexagonal, square, flat bars and transmission shafts at h9/h11 tolerances), structural profiles (UPN, UAC, IPN, IPE, HEA per EN 10025 / EN 10034), wire products (annealed, bright, twisted square), and nail products (construction, ring, headless, helical, machine, pallet). Annual nameplate capacity is 500,000 tons, supported by in-house billet preparation, on-site O2 production (since 1997), a full-automation natural-gas annealing furnace (2007), and an in-house materials testing laboratory equipped with Zwick/Roell tensile testers, Rockwell/Brinell hardness testers, Oxford Instruments spectrometers, Olympus microscopes, Jominy end-quench apparatus, and GE ultrasonic inspection. Quality and compliance certifications include ISO 9001 (TÜV, 2003), CE marking (KIWA, 2006), ISO 14001, ISO 45001, ISO 27001, EN 10025-1, and ISO 16120-3.

The company's revenue model is a B2B direct-sales hardware model with no publicly disclosed pricing. Two dedicated sales departments — one domestic, one export — handle transactions with construction, manufacturing, and industrial customers, with pricing quoted on specifications, volume, and delivery terms (multi-year contract cadence). Approximately 80% of production is exported to 120+ countries across six continents, supported by a Zonguldak port-side warehouse for Black Sea logistics, a Swiss trading subsidiary (Cag Steel AG in Zug), and a multilingual website in Turkish, English, German, French, Spanish, and Arabic. No third-party distributor or intermediary layer is in use; manufacturer-to-customer relationships are direct. The customer base is horizontal across three primary segments — construction and infrastructure, manufacturing industry, and agriculture and packaging — with no publicly named anchor customers.

Ownership is concentrated within the Güleç family: Kamil Güleç serves as Chairman of the Board and founded the company in 1978, while Çağrı Güleç serves as General Manager, indicating second-generation operating leadership. The broader corporate group includes wholly-owned subsidiaries in adjacent verticals: DEZ Madencilik (mining, logistics, freight handling at Turkish ports), Güleç Petrol and Şeyhoğlu Petrol (fuel stations and wholesale fuel), Özel Medikar Hastanesi (healthcare), Bey Çimento A.Ş. (cement from blast furnace slag; 20,000 tons/month; started April 2019 in Bandırma), GLC Mühendislik ve Otomasyon (engineering and Industry 4.0 automation), Karlikit A.Ş. (industrial gases), Güleç Müteahhitlik (construction contracting), Bulak Ekolojik Tarım (ecological agriculture), and Cag Steel AG (international steel trading in Zug, Switzerland). Notable rankings include ISO 500 rank 372, Fortune Turkey 500 rank 434 (2019), and Top 100 Turkish Exporters rank 183.
