The year 2008 was an important milestone in ArcelorMittal's development of new shapes of steel sheet piles. After its revamp in 2007, the rolling mill in Rodange managed to launch successfully the new PU-R range in 2008, starting in March with the PU 8R, then in June rolling the PU 10R, and later in September the PU 14R.
The latest PU 14R range is available in all steel grades of EN 10248 (1995), from S 240 GP to S 430 GP, in lengths up to 24.0 m, and can be paired and crimped on request. The main section has a thickness of 11.0 mm in the flange, and as the other U-sections, it can be rolled-up and down by 1.0 mm.
One noteworthy feature is the 675 mm width of the single pile. It lies between the 600 mm of PU sections, which are quite narrow and ideal for temporary applications where the sheets will be reused, and the 750 mm of the larger AU sheets, which have proven to be an excellent U-shape for permanent applications, especially when watertightness of the wall is paramount. Experts from the industry that were contacted during the development phase of the PU R range confirmed that this feature is a good compromise for such a sheet pile which is bound to be utilized in temporary as well as in permanent applications.
Mill A in Rodange already produced and shipped to the final customer 2 500 tonnes of the PU 14R.
Following table shows the different U-sections available in the range of section moduli Wx from 1 200 to 1 800 cm3/m.
