The X-350 is the WORLDS FIRST fully re-directive guardrail terminal end that can be used in Median, Tangent or Flared (up to 1200mm) installations.
With the length of need starting at post 1, instead of post 3 (as in other terminals) the X-350 provides a greater length of protective barrier reducing the cost of installation. During end on impacts, the X-350 absorbs energy at the impact head rather than transferring the resistance down the rail. Impact testing conducted at a 15° angle, showed the vehicle was re-directed and controlled instead of passing to the backside of the terminal.
As a result of further NCHRP 350 compliance crash testing on the X-350 Terminal End, the steel post X-350 Terminal Ends can also be installed at the higher height of 31” (787mm).
With the increase of 85mm from the ‘standard’ installation height this allows the NuGuard 31™ steel guardrail system to be terminated with an X-350 Steel Post Terminal End, without the need to have a height transition section over 2 lengths of W-section guardrail.
