THRIEBEAM Guardrail Crash Barriers

An important attribute of ThrieBeam guardrail car barriers are their high level of performance especially for large vehicles. Due to the greater height of the rail face, ThrieBeam guardrail provide reduced deflection and improved resistance to vehicle vaulting or under running.
The G9 and G9 Modified ThrieBeam systems are deemed to comply to NCHRP-350 TL3 and TL4 respectively, for a MASH TL4 compliant ThrieBeam system, please view our Ezy-Guard HC system.
THRIEBEAM guardrail should also be used in transition from W-Beam guardrail to more rigid barriers. This significantly reduces the deflection of the barrier system and provides are gradual stiffness transition into the rigid barrier.
