Dai Dung Metallic Manufacture Construction and Trade Corporation

What Dai Dung Metallic Manufacture Construction and Trade Corporation does

Dai Dung Metallic Manufacture Construction and Trade Corporation (DDC, Đại Dũng) is a Vietnamese integrated steel fabrication and EPC contractor founded in 1995 and headquartered in Ho Chi Minh City. The company operates six factory complexes spanning 120 hectares with combined production capacity of 300,000-500,000 tons of fabricated steel per year, including dedicated high-tech mechanical facilities at Ba Ria-Vung Tau (offshore wind components, 87,000 tons/year), Nghi Son, and An Ha (79,000 tons/year, LEED Gold). DDC delivers structural steel, heavy mechanical components, oil and gas storage tanks, and offshore wind foundations (monopiles, jackets, suction buckets) to multinational customers across 50-60 countries, with marquee projects including Ørsted's Greater Changhua wind farm, BAE Systems' Shiplift Platform, the TotalEnergies-led EACOP pipeline, Freeport-McMoRan's Manyar Smelter, Hoa Phát's Dung Quất steel complex, and Qatar World Cup stadiums.

The business runs on five integrated service lines: design consultancy and project management (using Tekla Structures/BIM), fabrication and manufacturing across the six factory clusters, on-site erection and construction, full-scope EPC contracting, and ongoing maintenance services. Underlying technology includes CNC laser cutting (up to 30kW), automated SAW welding lines, RFID/barcode/QR traceability, and 500T/1000T heavy-lift cranes capable of handling super-sized and super-heavy components. DDC holds ISO 9001/14001/45001/3834, AISC, EN 1090-1 EXC 4, AS/NZS 5131, and LEED Gold certifications, qualifying it for US, European, Australian, and Asian project standards.

Revenue is generated through multi-year lump-sum turnkey EPC contracts, per-tonnage hardware sales of fabricated steel, professional design and engineering fees, and recurring maintenance service contracts. The company sells primarily through direct enterprise engagement with project owners, EPC prime contractors, and government entities, supplemented by international trade events and a Vietnamese/English corporate website. The company is privately held (a Vietnamese joint-stock company, Công ty cổ phần), led by Chairman Trịnh Tiến Dũng, and is currently expanding into commercial shipbuilding and port equipment (via a 2026 strategic partnership with Konecranes).
