Product Overview

U Type Steel Sheet Pile is a hot-rolled interlocking steel retaining member designed for temporary and permanent earth-retaining and water-barrier structures. With its U-shaped profile and reliable interlock connection system, it creates continuous retaining walls for civil engineering, hydraulic projects and foundation construction.

Manufactured according to international standards including GB/T 2093-2014, ASTM A6/A6M-22, EN 10248-1-2017 and JIS G3192-2018, U Type Steel Sheet Pile is available in multiple global standard series, including Chinese SP series, European U series and American PU series.

The product range covers SP-III, SP-IV, SP-V, SP-VI, U250-U600 and PU12-PU20 specifications. Different steel grades, dimensions and corrosion protection options are available to meet various excavation depths, marine environments and infrastructure requirements.

U Type Steel Sheet Pile provides high bending stiffness, reliable soil retention and water-stop performance through its interlocking clutch design. It is widely used in deep foundation pits, river revetment, port wharf construction, municipal trench support, flood-control engineering and offshore auxiliary structures.
