DYWIDAG Bar Systems are perfectly suitable for transferring tensile forces and can therefore be used as tie rods.
Applications: Sheet pile wall assembly in harbor and dam construction, cross-linkings, tying back walls in deadman structures, positional stability of joint connections, corner joints and foundations etc.

Due to the continuous GEWl® Thread, the bars can be cut, anchored, and coupled at any point and be adjusted to on-site requirements. This makes the system completely independent of installation conditions on site as well as of existing deviations or alterations.

Depending on requirements and steel grades, a variety of corrosion protection methods can be used.
