What is the difference between U piles and Z piles?
Z-shaped sheet piles are considered to be the most efficient of the shapes. They are used for intermediate and deep wall construction and commonly for tied back and cantilever retaining walls. U-shaped profiles are used for similar applications, but their resistance to bending is lower than Z-shaped piles.
For sheet piling, most widely used steel grade:S235 S275 for cold rolled sheet piles, S355GP, S390GP, S430GP in Europe.In China, Q235B and Q345B are most widely used. In Japan, SY295 and SY390 are most used. For pipe piling, API 5L and EN10219 covers over 80% of all steel grades.
