- Sungdo Engineering & Construction Co., Ltd. (KRX: 037350), commonly referred to as Sungdo ENG, is a South Korea-based engineering, procurement, and construction (EPC) company specializing in high-tech industrial facilities, cleanroom systems, specialized process plants, and general civil construction. Founded in 1987 and headquartered in Seoul, South Korea, the company delivers comprehensive turn-key engineering solutions to advanced manufacturing and process industries, including semiconductors, flat-panel displays, electric vehicle (EV) secondary batteries, biotechnology, pharmaceuticals, petrochemicals, and energy infrastructure.
The company operates through three core business segments: High-Tech Industrial Facilities, Plant Engineering, and General Construction. Its primary products and services include cleanroom design, engineering, and construction, featuring heating, ventilation, and air conditioning (HVAC) systems, laminar flow process stations, micro-contamination control, and ultra-pure environmental regulation for semiconductor and display fabrication; specialized ultra-high purity (UHP) piping, gas delivery systems, and chemical distribution infrastructure; turnkey secondary battery plant EPC services covering cathode active material synthesis, cell manufacturing, module assembly, and battery pack production lines; biopharmaceutical and healthcare facility construction compliant with Good Manufacturing Practice (GMP), Good Laboratory Practice (GLP), and Hazard Analysis Critical Control Point (HACCP) standards; industrial plant engineering for thermal, co-generation, and combined-cycle power facilities; industrial specialty gas plants, chemical processing systems, and environmental pollution control installations including desulfurization and denitrification systems; general commercial, residential, and industrial civil engineering; and comprehensive facility lifecycle support comprising project management, basic and detailed engineering design, equipment procurement, commissioning, and post-construction maintenance.
Sungdo Engineering & Construction maintains an extensive international operating footprint spanning South Korea, North America, Europe, Southeast Asia, and the Middle East. It operates multiple overseas subsidiaries and regional offices, including Sungdo ENG USA Inc., Sungdo ENG Hungary Kft., and Sungdo ENG Poland Sp. z o.o., alongside entities in China, Vietnam, Thailand, Malaysia, Saudi Arabia, and Kuwait. The company also maintains a significant equity stake in its listed affiliate STI Co., Ltd. (KRX: 039440), a manufacturer of semiconductor wet processing equipment and central chemical delivery systems.
In recent developments, Sungdo Engineering & Construction has accelerated its global expansion strategy by scaling its overseas EPC operations to support battery and semiconductor manufacturers building regional supply chains in Europe and North America. The company has strengthened its European operations centered around its Hungarian and Polish hubs to capture high-value contracts for electric vehicle battery gigafactories and cathode materials facilities across Central and Eastern Europe. In North America, the company has expanded its engineering and project execution capacity in the southeastern United States to address growing demand for localized cleanroom and utility installations in the advanced electronics and battery sectors. Furthermore, Sungdo ENG has enhanced its collaborative synergies with affiliate STI Co., Ltd. to provide integrated chemical delivery and cleanroom turnkey solutions for next-generation semiconductor fabrication facilities while diversifying into bio-health manufacturing and green energy infrastructure projects.
