U sections

Millions of tonnes of U-shaped sheet piles have been used all over the world for all kind of structures for more than 100 years. The advantages of U-shaped piles are multiple:

• wide range of sections,
• excellent statical properties,
• great aptitude for re-use and driving into compact soils, especially the sections with reinforced shoulders (PU 22,...),
• very good installation quality and performance.

ArcelorMittal supplies 3 types of sheet piles from the mills in Belval (Luxembourg) and Dabrowa (Poland):

• AU™ : 750 mm wide piles (Belval),
• PU^® : 600 mm wide piles (Belval),
• GU^®-N : 400 and 600 mm wide piles (Dabrowa).

All our U-type sheet piles have the proven Larssen interlock.

U-type sheet piles are usually supplied as double piles, with the common interlock crimped (several patterns are available), or welded (more expensive). Triple piles are usually supplied with one common interlock crimped and the second one (partially) welded.

According to European design standards (EN 1993-5): reduction factors may have to be applied to the section properties of double / triple U-piles (with crimped and/or welded interlocks), but for single piles (including double / triple piles without crimped / welded interlocks), reduction factors have to be applied.
