The main plant for bridge and steel frames is the Osaka Plant, which serves not only the domestic market in Japan but also the production for export products. It has its own in-house production system which covers the entire bridge production process, and is equipped with Japan’s first automated full-scale drawing system, NC machines, automated assembly and welding lines, and computerized measurement system for steel members.

It also has its own wharf where barges can berth, allowing long and large bridge segments and large steel structures such as the segments for Honshu-shikoku Connection Bridges and Kansai International Airport, etc. to be transported directly by sea.
