Briefly ...

Steel restraint systems are linear elements designed to straighten the path of vehicles. They are made by assembling steel components.

In accordance with NBN EN1317-1/2/5, the performance are:

  • Minimum containment level: N2(=TL2*)

  • Maximum working width : Wn 4

  • Vehicle intrusion  : VIn 3

  • Acceleration Severity Index : ASI A!

The additional features are:

  • To ensure the guardrail function, the overall height in relation to the concrete support ≥1,20 m

  • To limit the influence on the structure, the maximum space requirement between front and rear post face = 28 cm 

  • To limit or even avoid reinforcements, the forces transmitted by post are M=3,1 kNm, V=12,5 kN 

  • For maintenance reasons and possible in situ push tests the fussible system it is located outside of the anchorage, meaning , on the post.

Guardrail fonction:

  • Handrail height at 1.2m.

  • Filling preventing the passage of a 15cm diameter cylinder.
