The symbol mark depicts the Taehwagang River (a symbol of Ulsan) and the letter U (Ulsan's initial), rendered in a dynamic yet elegant flow and harmonized through red, blue, and green, the three primary colors of light.

Just as the Taehwagang River has always stood by Ulsan's side and united its citizens, the symbol represents the Corporation's commitment to remain constantly together with the citizens of Ulsan and to work for their happiness.

Red represents the Corporation's warmth and passion for its citizens, blue represents the hope and dynamic vision for Ulsan's bright future, and green represents the city's pleasant, beautifully maintained green spaces.
