We can provide high-quality concrete composite segments because we carry out everything from steel frame fabrication to concrete placement at our specialized factory.We perform all processes from design to manufacturing and guarantee high quality.

As a composite structure of steel members and concrete, it meets various soil conditions.It can be used under those severe load conditions that conventional steel segments and RC segments cannot support.

Its high strength enables use of lining thinner than one required for steel segments and RC segments under the same conditions, thus reducing cost.

We will flexibly respond to requests for desired segment sizes, concrete specifications, and joint specifications (boltless, etc.).
