    RR® and RD® piles design and installation manual

    RR® pile

    Driven RR large diameter piles (RR400–RR1200) are steel pipe piles consisting of a spirally welded steel pipe and an optional pile tip.

    The key benefits include high load-bearing capacity, great stiffness and bending strength due to their shape, and high installation strength due to the steel's strength.

    RD® pile

    Drilled RD large diameter piles (RD400–RD1200) are special piles installed by drilling in difficult ground and environmental conditions.

    Piles consist of a longitudinally or spirally welded steel pipe. They may be drilled through all natural soil layers all the way into bedrock, with small deviations in position and inclination.

    Coatings

    For structures in severe conditions, it may be beneficial to protect entire piles or parts with external coatings.

    SSAB can deliver pile pipes with several protective coating methods.
