HANSAE CO., LTD.

What HANSAE CO., LTD. does

HANSAE CO., LTD. (주식회사 한세) is a privately held Korean non-ferrous metal materials manufacturer founded in 2004 and headquartered at 44 Waji Gongdan 2-gil, Ulju-gun, Ulsan Metropolitan City. The company operates a single core division — its Pipe Division — producing welded pipes, seamless pipes, fin tubes, and copper-nickel pipes primarily for shipbuilding, maritime, power plant, and industrial plant end-markets. Its technology base centers on proprietary materials and welding process know-how, including Cu-Cr-Zr high-strength heat-resistant copper alloy materials (claimed lifespan more than 3x conventional products), semi-auto MIG and automated TIG welding techniques (claimed 1.5x faster pipeline process time), and the first domestic Korean production capability for 14-inch (OD368mm) copper-nickel seamless pipe.

HANSAE generates revenue through direct B2B sales to large industrial customers, securing vendor registrations with major shipbuilders and energy companies and exporting to the USA, UAE, Taiwan, Malaysia, Japan, and Europe. Named customers include Samsung Heavy Industries, Hyundai Mipo Dockyard, DSME, STX Heavy Industries, Hanwha Ocean, MMHE Malaysia, ADNOC, and FLOUR; pricing is negotiated on a per-contract basis with no public rate card. The company holds an extensive regulatory and certification portfolio — five maritime classification society approvals (ABS, BV, LR, DNV, RMRS), CE/PED, ISO 9001/14001/45001, and Korean government designations (Inno-Biz, Main-Biz, Materials & Components Specialized) — which constitutes a meaningful barrier to entry in marine pipe supply.

The company is led by CEO Lee Jae Hwal (이재활), was renamed from DONG WOO E&C Co., Ltd. in 2016, and has been recognized by KITA Export Tower Awards at the USD 5 million (2014) and USD 10 million (2015) thresholds, by Ulju County for export excellence (2024), and as a Sharing Management Leader (2025). HANSAE has set a stated long-term revenue target of KRW 100 billion (1,000억원), most recently pursued through incremental customer expansion in North America and Taiwan documented in early 2026.
