Crash barrier

Crash barriers must ensure that accidental injury and damage to persons and equipment are minimised, and that the consequential damage after a collision becomes as limited as possible. This means that vehicles colliding with the guardrail must continue along the guardrail or be thrown back at as small an angle as possible, thus minimising the extent of the damage.

​Impact tests according to European standards

The dynamic conditions of a collision are often complex. The correct assessment of the function of a crash barrier is obtained by conducting collision tests. The tests are carried out in accordance with European standards: EN1317-1, EN1317-2, and EN1317-5, which determine which functional requirements the crash barrier can meet.

The choice of crash barrier will, as a starting point, be made on the basis of the most common accident situation, mostly when driving a passenger car. In a number of situations, there may be a reason to choose a crash barrier which can handle the collision of larger vehicles, in situations such as:

  • ​​A high percentage of heavy vehicles and high annual traffic on the route.
  • ​Situations where the breakthrough of a crash barrier with a larger vehicle has particularly serious consequences.
  • Stretches where the accident statistics indicate that a higher strength class should be selected.​

​Road safety experts

​The crash barrier is 100% adapted to the specific task. As experts in road safety, we advise our clients in a wide range of matters regarding specific tasks. The advice includes the choice of types of crash barriers, whether reinforcements should be established at bridges or other fixed objects, whether safety distances are kept and whether the solution can be advantageously carried out with single or double-sided barrier.

After the delivery, we check the crash barrier for correct tightening, visual escape line, the placement of the scepter in relation to position/solder and the coating thickness of the galvanisation.
