High-grade tension and compression rod systems for buildings and civils
Our tension rods are made of S540N, an extra-high-quality modied S460N with a guaranteed yieldstrength of 540 N/mm. Another unique feature of BESISTA
are hot-dip galvanized rod threads for
sustainable construction.
Please make use of our unique, cost-effective thread sizes M14, 18, 22, 33, 39, 45 and 68,whichare marked red in the picture. Sizes M8, 27, 52, 60, 72 and 76 half-red in the picture are likewiseonly partially available from other manufacturers. BESISTA
is the only tension rod manufacturer
to supply all possible sizes between M8 and M76. This allows tremendous cost savings whileconserving valuable materials.To capitalize on these relevant advantages, unique to BESISTA
,
please select the optimum sizes in your structural designand always state the limit tensile forcesin the tendering specication.

Note:Given that, for BESISTA tension rod systems, the required thread screw-in depth and corrosion protec-tion are ensured by the inspection hole, the cover sleeves are not structurally necessary.

540tension rods
Tension rods of S540Nmust be supplied exclusively by BESISTA International GmbH. In order to avoid confu-sions with steel of lower strength, BESISTA International GmbH is always supplies S540N as standard - even ifS460N, S355 or S235 would be sufcient under the design.
Tension rods of S355and S235can also be supplied by others. In such cases, the quality has to be certied bythe client. Compliance with the provisions of the European Technical Approval issued by DIBt, Berlin, andBESISTA International GmbH shall be ensured. As a rule, however, tension rods should be obtained fromBESISTA International GmbH together with the rod anchors as an integral BESISTA tension rod system.
Note:When using extension and tensioning sleeves, the thread lengths of the tension rods are shorter.

540extension and tensioning sleeves
The extension sleeveswith continuous, right-hand internal threads are used to extend and secure the tensionrods. For additional safety the threads of BESISTA sleeves are longer than necessary.
Note: The tension rods must be securely lockedat the centre of the sleeve to ensure that the complete rod isturned when tensioning. The thread screw-in depth is reached when the rod threads project from the sleeve on
both sides by no more than 4 thread pitches.
The tensioning sleeveswith left- and right-hand threads are used to pretension the tension rods. They canalso be used as turnbuckles, e.g. in order to increase the adjustment distance.
Note: The required thread screw-in depth is reached when, after the tensioning process, the threads arevisible in both inspection holes.

All types are individually manufactured by BESISTA International GmbH in accordance with the clients structuralcheck on load-carrying capacity. Welding of the compression rod connections to the steel tubes is carriedout by others.Please note: For compression loads, the pin diameters are larger than those of standard pins for tensileloads. In order to limit the critical transition distance L, the adjustment distance LVis also shorter than for ten-sion rods.
Type 2: one-part, as machined com-ponent made of S355 for timber or forwelding to steel tubes made of S355

Data form, compression rod connections
Note for dimensioning:proof of buckling strength also in transition distance L shall be provided by the
structural engineer. The BESISTAsafety rod systems installation instructions shall be observed. The dimensi-ons for the compression rod connections shall be individually determined by BESISTA International GmbH andthe connections specially manufactured.
BESISTArod anchors are able to transmit both tensile and compressive forces under the European TechnicalApproval ETA-08/0038, see MENU Design loads page 4. For compression loads, the pin diametersare lar-ger than those of standard pins for tensile loads. See MENU Technical data page 5 or ETA Annex 7. In orderto minimize the buckling length in the transition distance L, the adjustment distances are shortened, deviatingfrom the standard length of the tension rods.
BESISTA
compression rod systems are available in three types:the lower-cost type 1as machined solid rodsmade of S540N up to 76. Type 2as one-part machined components made of S355 for timber or for weldingby others to steel tubes made of S355. Type 3two-part, consisting of a machined component made of S355 fortimber or for welding by others and higher strength thread pins made of S540N. The connection geometry forboth types is the same.
