PHC Pile

PHC Pile

With changing perceptions of building structures' stability due to increases in the height and size of buildings and earthquakes, there is a growing demand for high-performance PHC piles to reinforce foundations.

  • Excellent resistance to creep and shrinkage of concrete
  • High bearing capacity and strong resistance to strike
