Guardrail Rigid Transition
Guardrail Rigid Transition
Guardrail Rigid Transitions provide secure, compliant connections between flexible W-Beam or Thrie-Beam guardrails and rigid concrete barriers. With Austroads transitioning to MASH-compliant systems, these legacy transitions may no longer be approved for new installations. For MASH TL3-compliant alternatives, consult your local Ingal Civil representative about the Ingal RBT system.

Frequently asked questions
- What is the Guardrail Rigid Transition used for?View
It provides a secure, compliant connection between semi-rigid guardrail systems (such as W-Beam or Thrie-Beam) and rigid concrete barriers/structures (for example bridge parapets or concrete traffic barriers).
- Can the rails in the transition section be curved or used on bends?View
No, the manual clearly states that curving of the thrie-beam rails within this transition system is not permitted.
- What happens if my project requires MASH compliance?View
