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 EN 1317-1/2/5, the performance are:

  • Minimum containment level: N2 (=TL2)

  • Maximum working widthe : Wn 3

  • Vehicle intrusion = VIn 3

  • Acceleration Severity Index (ASI) =  ASI B

The additional features are:

  • Minimum distance between posts = 6 m

  • 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 = 40 cm

  • For aesthetic reasons, the longitudinal elements are tubes with a diameter of:  10 and 12 cm +/- 1 cm

  • For aesthetic reasons, the connections between the longitudinal elements are not visible on the 180° front panel (the fixing points will only be located on the 180° rear panel)

  • In order to limit the number of sealing holes, the average number of anchors per meter of device = 0.33 pieces/m

  • To limit or even avoid reinforcements, the forces transmitted by post 4.0 are M=14 kNm, V=43 kN

Guardrail fonction:

  • Handrail height at 1.2m.

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

  • CE certification of the entire system (slide + filling).
