                            Retaining wall structures based on steel piles

                            Retaining wall structures based on steel piles are often the best solution to replace traditional, labor-intensive cast-in-place based retaining wall structures.

                            RR? large diameter piles can be built into a continuous combi wall by welding interlocking sections or complete sheet piles into them. In a combi wall, piles act as the load-bearing structure, while sheet piles installed in between make the wall continuous.

                            Thanks to SSAB’s high-grade steel, our combi walls have excellent bending stiffness and resistance.


                            Applications:

                            • Retaining wall structures
                            • Building foundations
                            • Wharves and piers
                            • Road and railway structures
                            • Bridges
