Fuse system:

• saving installation time

• preservation of the support (concrete)

The lowest transmitted efforts of the market:

​

M=3,1 kNm

V=12,5 kN/post

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 width : Wn 4

​

• Vehicle intrusion = VIn 3

​

• Acceleration Severity Index (ASI) =  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 4.0 are M=14 kNm, V=43 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.

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