NOKSEL

What NOKSEL does

NOKSEL (legal name: Noksel Çelik Boru Sanayi Anonim Şirketi) is a Turkish-headquartered steel pipe manufacturer founded in 1987, specializing in spiral welded (HSAW/SSAW) and longitudinally welded (HFI/ERW) steel pipes for the oil, natural gas, water transmission, and piling/construction sectors. The company operates four production facilities — three in Turkey (Ankara HQ, Hendek and İskenderun factories) and one in Spain (Lorca plant under the Noksel España subsidiary, established 2008, producing since 2011) — with capability across a wide product range: spiral pipes with 219.1–3,300 mm diameters, 4–26 mm wall thicknesses, and up to 18.5 m standard or 40 m piling lengths; ERW/HFI pipes in 10.0–168.3 mm diameters with square, rectangular, and D profile variants; steel profiles for solar mounting structures; and TS EN ISO/IEC 17025 accredited in-house testing laboratories at Hendek and İskenderun.

The company's business model is direct B2B, quote-based manufacturing and sale of steel pipes and profiles to enterprise and government customers across oil & gas transmission, water infrastructure, piling and construction, shipbuilding, and (newer) renewable energy. Revenue is hardware sales, with pricing on a per-unit basis for downloadable catalogs (HFI/ERW pipes and profiles from Hendek) and bespoke tender pricing for large-diameter spiral pipe projects; the company reports $503M USD in annual sales and exports to 71+ countries. Marquee project references include the Baku-Tbilisi-Ceyhan crude pipeline (2005), the TANAP gas pipeline consortium (2014–2018, ~350,000 mt / ~30% of a $420M tender alongside Borusan and Erciyas), Kızılırmak Water, Osmangazi Bridge, Istanbul Strait Tunnel, and Thirlmere Link Mains. Certification stack includes API 5L, API Spec Q1, ISO 9001/14001/45001, ISO/IEC 17025, EN 10217/10219/10224, AWWA C 200, and GOST 20295 across all production sites, forming the regulatory entry ticket for international pipeline tenders. Raw material sourcing is diversified across ArcelorMittal, POSCO, Erdemir, Çolakoğlu, İsdemir, Metinvest, and Mapa.

Ownership remains with the founding Paksu family (Osman Nurettin Paksu as Chairman, Ahmet Teyfik Paksu as Vice Chairman, Ağasoy Okumuş as Member & CEO), and the company has entered an IPO process with Board Resolution No. 307 dated 30.10.2025 approving a public offering of shares under the registered capital system. In 2024 NOKSEL publicly pivoted toward renewable energy, carbon accounting, and zero-carbon production, launching steel profiles for PV and solar thermal mounting structures as a new product vertical beyond its legacy oil, gas, and water base.
