Compression rod systems for steel construction, facade engineering and timber construction
The BESISTA® compression rod systems for steel are available in three types. The connection geometry is the same for all types.
Type 1: machined solid rods
Especially for short compression rods, machined solid rods are the least expensive option. The rods are made of S540N. They can be completely hot-dip galvanized. As with the tension rods, wrench flats are provided for tensioning.
Type 2: one-part compression rod connections
With this type, the compression rod connections are in one piece, with a machined threaded portion. They are made of S355 for welding by others to S355 steel tube.
All components – including the rod threads – are hot-dip galvanized. Only the weld seam needs to be cold galvanized.
Type 3: two-part compression rod connections
With type 3, the compression rod connections are in two pieces, consisting of a machined component made of S355 for welding by others to S355 steel tube and a higher-strength threaded pin, made of e.g. S540N or 42CrMo4. The higher-strength threaded pins can accommodate higher buckling and tensile forces.
This patented type may only be manufactured and delivered by BESISTA®.
Compression rod connections for timber compression rods
Compression rod connections for timber rods are another BESISTA® speciality. These are always two-part connections with higher-strength pins.
The tapered machined components can be made of any steel grade or cast, as required to accommodate the load.
A wide range of options are available for connection to the wood. These are specified in function of the particular requirements.
