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.

Software for fast and easy design
RRPileCalc is a design program for SSAB's steel piles. Eurocodes as well as National codes and instructions are applied in the end-bearing pile design.
PileWallCalc design tool enables easy calculation of cross section properties and bending resistances of the pile walls. The program calculates the bending resistances and normal force resistances of RD® pile wall, Combi wall and Zig-Zag Combi wall.
SSAB develops new products and services in order to improve our customers’ performance in sustainability and overall efficiency.
Life cycle assessment data for SSAB’s products are available in the form of Environmental product declarations (EPDs). Manufacturing chain from raw material to finished product is carefully managed.
SSAB has introduced CE marking for infrastructure products. Declarations of Performance (DoP) indicate the technical characteristics of CE-marked products.
