Cold Rolled U Type Steel Sheet Pile EN10249-1 EN10249-2 for Harbor and Cofferdam Construction

1．Product Overview

Cold rolled U type steel sheet piles are structural retaining components designed for temporary and permanent foundation support systems. The symmetrical U-shaped profile provides efficient structural performance, convenient installation, and reliable interlocking for retaining wall and cofferdam applications.

Compared with conventional retaining structures, U type sheet piles offer faster installation, reusable performance, and effective earth and water retention capabilities. These products are widely used in ports, bridges, shipyards, flood control systems, underground construction, and marine engineering projects.

2．Technical Solution

The cold rolling manufacturing process ensures dimensional consistency, stable interlock geometry, and controlled section properties. The symmetrical profile design allows convenient assembly into double piles, improving installation efficiency and alignment performance during construction.

Cold rolled U sheet piles can be supplied in different structural forms and steel grades to meet project requirements for load-bearing capacity, corrosion resistance, and service life.
