From a legal perspective, rod systems may only be preassembled at the customer’s express wish and on the customer’s own responsibility. Yet, a host of reasons speak against this.
Although preassembled rod systems are often touted as a selling point, BESISTA® rejects this practice. The fact that the rod anchors at the ends are far thicker than the tension rods makes preassembled systems extremely bulky and difficult to transport. It is impossible, without an inordinate amount of effort, to properly secure preassembled rod systems on trucks. The problem becomes particularly acute where unloading and reloading is necessary during transit. The transportation of preassembled systems is also difficult to reconcile with existing European regulations.
Moreover, preassembled rod systems are particularly prone to damage and deformation during shipment and on site. Another potential hazard – especially with long rods – is that the rod anchors may work loose during transportation and cause serious accidents. All these risks mean that nobody can accept liability for bent or damaged preassembled rod systems. Moreover, all technical approvals – which are identical for all manufacturers – cease to be valid for bent or damaged systems.
To minimize the risk of damage during shipment, BESISTA® ensures that the rods are properly prepared for transportation and for movement by stackers, forklifts and cranes: placed on skids and arranged parallel in bundles to maximize stiffness, with threads well-protected. BESISTA® ships its rod anchors, pins and locking rings as well sorted and protected consignments in robust boxes or cage pallets. Thanks to this careful packaging, BESISTA® has, over its 25-year history, kept a clean sheet in terms of damage or any other transport-related problems.
Proper packaging offers better protection whenever rod systems need to be stored for extended periods, especially on building sites. This also makes them easier to move with simple equipment than bulky preassembled systems.
BESISTA® products do not require factory preassembly to check the fit of all system components. This is because, in line with precise standard engineering practice, our threads are manufactured and checked using thread gauges. BESISTA® customers can testify to our 25-year track record of perfect fit.
To ensure high-quality assembly, BESISTA® recommend that the threads be rechecked for cleanliness immediately prior to installation. Only then should the threads be liberally greased and the system assembled in accordance with the enclosed guidelines – see MENU point “Installation instructions”.
The hot-dip galvanized rod threads allow rapid, efficient installation. The rods screw into the rod anchors like a bolt into a nut, without the need for any additional elaborate works such as sealing or spraying.
