Vinatech ES Electronics Factory is invested by Vinatech ES Co., Ltd — a subsidiary of Vinatech Group (South Korea).
This is an FDI project in the green energy sector, specializing in the production of supercapacitors and Energy Storage Systems (ESS). This product group plays a core role in renewable energy storage systems and smart grids, aligning with the trend of BESS (Battery Energy Storage System) solutions currently being developed by many major technology corporations. In this project, Hai Long was selected to process, fabricate, and transport over 2,000 tons of factory steel structure.

The entire volume of factory steel structure for Phase 1 of the project — 3ha out of a total scale of 17ha, with an investment of 45 million USD — has been processed, fabricated, and transported by the team of engineers and workers at Hai Long Steel Structure. For a supercapacitor factory project, the selection of a steel structure contractor always comes with strict evaluation criteria: production capacity, material quality control capability, and delivery schedule.
In parallel with the completion of Vinatech ES, Hai Long is continuing to implement other steel structure projects such as LNG Elton – a project for export to the West African market. At the same time, it is producing and supplying steel structures for projects where Hai Long acts as the general contractor. This is an advantage that helps Hai Long be proactive in terms of schedule and quality control from fabrication to installation, rather than depending on external suppliers.
The project has been completed, marking the next milestone on the journey toward achieving the production target in 2026, and also affirming the position of Hai Long Steel Structure with international partners.
