    Round steel anchors for flexible use

    A special version of our anchor screws are the round steel anchors. When sheet pile walls are anchored at the back, they transfer the contact force of the sheet pile wall to the anchor wall. They can be designed flexibly and are therefore the most economical type of sheet pile anchoring. At alstertaler you get:

    • Anchor with compressed and rolled thread according to EAU 2020 (Kt = 0.55)
    • Anchor with compressed and rolled thread according to DIN EN 1993-5 (Kt = 0.6 or 0.9)
    • Anchor with rolled thread according to DIN EN 1993-5 (Kt = 0.9)
    • Eye anchor
    • Hammerhead anchor

    Other areas of application include civil engineering, steel and hydraulic engineering as well as concrete and plant construction.
