Combined wall with tubular piles
In cooperation with ArcelorMittal Projects, ArcelorMittal Commercial RPS supplies spirally welded tubular piles from its mill in Dintelmond (NL) delivered with EN 10204 - 2004 certification. Equipped with a deep-water quay, the Dutch mill can export tubular foundation piles with diameters up to 3000 mm, wall thicknesses up to 25 mm, and lengths up to 49 m without butt-welding.
Tubular piles are available in numerous European and US steel grades due to ArcelorMittal’s worldwide network of coil producers. The piles can be coated on request and are provided with C9 connectors. Tubular piles are the main retaining elements of the combined wall, carrying horizontal loads from soil and water pressures and vertical foundation loads. The intermediary Z-type sheet piles transfer horizontal loads to the tubular piles. The table below gives an overview of some of the possible combined wall systems. The table is valid for C9 connectors. Please refer to our brochure “Spirally welded steel pipes” for further details.
