Tension rods made of S355 and S235 can also be supplied by the others. The data in the tables below solely serve to assist with dimensioning in cases where the tension rods are manufactured by others. In such cases, the quality shall be certified by the client. Compliance with the provisions of European Technical Approval ETA-08/0038 and BESISTA International GmbH shall be ensured. As a rule, however, tension rods should be obtained from BESISTA International GmbH together with the rod anchors as an integral BESISTA tension rod system.
Given that, for BESISTA tension rod systems, the required thread screw-in depth and corrosion protection are ensured by the inspection hole, the cover sleeves are not structurally necessary.
