Thrie-Beam Guardrail

Metal Fencing Specialists have over three decades of experience in the supply and installation of guardrail systems and safety barriers. Our professional installers have completed Thrie-Beam projects on freeways, residential streets and private roads nationwide.  

All our guardrails are strictly manufactured to meet Australian Standards. The Thrie-Beam can be installed on verges or medians and even on small curves in the road, with the option of standard blocking installation or with modified blocking pieces for heavy vehicle impacts.

The Thrie-Beam shares similar characteristics with the W-Beam Guardrail. Much like the W-Beam, the Thrie-Beam also consists of a post and block design which reduces wheel snagging and the possibility of the vehicle hurdling over the guardrail barrier.

However, the additional corrugation which is featured in the Thrie-Beam Guardrail stiffens the system, making it less prone to damage during low-moderate speed vehicle impacts, providing a comparatively sturdier guardrail system that can withstand greater impact force. It also allows higher mounting of the rail, which increases the ability to contain vehicles larger than standard passenger cars under some impact conditions.

  • Supplied in Hot Dip galvanised form (for reinforced strength and improved longevity) ready for installation
  • Additional corrugation in rail element stiffens the system making it better able to encounter larger impact
  • Shields hazards located in close proximity to the edge of the roadway
  • Post and Block design reduces wheel snagging and the consequential effects of vehicle roll over occurring
  • Performs well on the outside of curves (even those of small radius) as concave shape supports the development of tension in the rail
  • Can be used in verge or median locations
