On June 15, 2022, Hai Long Construction JSC was honored to welcome very special guests from Sumitomo Electric Industries – Japan and partners SSG, Takebishi, JSS, and LG MEC, who collaborated on the energy storage battery container production project for the client, Sumitomo.
This was a new and challenging project for Hai Long Construction; however, after nearly a year of cooperation with the selected production units, Hai Long Construction completed the project very successfully and received praise from the client, Sumitomo. To express their trust and desire to continue cooperating with Hai Long Construction on future projects, Sumitomo Electric Industries wrote a thank-you letter and sent representatives to Vietnam to present it directly to the representative of Hai Long Construction JSC.


Sumitomo's encouragement is a great source of motivation for Hai Long Construction to strive to continue successfully completing upcoming projects. Hai Long Construction would like to sincerely thank our clients for their trust in Hai Long and will constantly strive to develop further to provide the highest quality services to our valued clients.
