KCTB cast-in-place steel pipe concrete pile

Excavated residual soil and concrete volume reduced by up to 40%! The outer diameter, thickness, and material of the steel pipe can be freely designed.

The "KCTB cast-in-place steel pipe concrete pile" is a composite of steel pipes and concrete, featuring high ductility and strong resistance to earthquakes. By reducing the shaft diameter, the amount of excavated soil and concrete can be reduced by up to 40%. It can withstand large bending and shear forces. Additionally, the upper limit of the concrete design strength (Fc) is 45 N/mm², ensuring high safety and enabling economical design. 【Features】 ■ Significantly reduced shaft diameter compared to ordinary cast-in-place concrete piles ■ High ductility provides great safety during earthquakes ■ High bending stiffness and shear resistance ■ High design flexibility ■ High concrete design strength *For more details, please refer to the PDF materials or feel free to contact us.
