U Sections

Since the beginning of the 20th century millions of tons of U sheet piles have been used all over the world for every kind of structure.

The advantages of U piles are multiple:

  • A wide range of sections forming several series with various geometrical characteristics, offering the choice of the section technically and economically best suited for a specific project.
  • Easy fixing of tie rods and swivelling attachments, even under water.
