Sentry Barrier & Sentry Median Barrier System

The Sentry Barrier is a roadside W-Beam guardrail system suitable for containing, redirecting and shielding vehicles from roadside obstacles. The barrier has been designed and tested to meet the evaluation criteria of MASH Test Level 3 (TL-3) for a longitudinal barrier. This is the current state of the art performance criteria, exceeding the requirements of NCHRP 350 TL-3.

The Sentry Median Barrier is a W-Beam guardrail system suitable for containing, redirecting and shielding vehicles from opposing traffic or dual carriageways.

FEATURES

MASH TL-3 compliant as a permanent longitudinal barrier system
AS3845: 2015 compliant and recommended for acceptance by the Austroads Safety Barrier Assessment Panel (ASBAP)
Minimal parts make repair easier
Superior dynamic deflection results with added testing on a zero offset to the batter hinge for the roadside Sentry Barrier guardrail system
Conventional ‘C’ shaped post with a shorter, smaller profile
No block out, stiffener or bracket between rail and post connection
Large flexibility and tolerance in system height to accommodate easy transitioning
Easily capable of transition to W-Beam, Thrie-Beam public domain and proprietary terminals
Crash tested and recommended for use with a Max-Tension™ Terminal End
Bolt down Sentry post option available - used on concrete ground beam where services or ground conditions do not allow use of driven posts.
