Spatial Structure Engineering

“Special steel structure technology” is used to construct beautiful and dynamic large spaces, such as soccer stadiums and other types of athletic event space.

We carry out everything from structural design to fabrication and construction work, utilizing the Nippon Steel & Sumitomo Metal Group’s unique technology making and using steel.
