Outline

ULBON for piles is the only high-strength rebar in Japan that can also be used for shear reinforcement of cast-in-place piles, improving cost and workability.

Using cast-in-place piles are one of the most common methods of constructing pile foundations to prevent toppling over and settlement of heavy buildings.
