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 barrier 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.
