- Description DescriptionDescriptionFlexbeam Thrie-beam rail is used in semi-rigid safety barriers in multiple applications and is integral to the safe and efficient redirection. The increased installation height, surface area and rigidity of Thrie-Beam rail provide reductions in deflection and higher levels of containment compared to W-Beam rail. As a result Thrie-Beam rail is used in all MASH Transitions to Rigid Structures.Flexbeam Thrie-Beam Rail may be installed directly onto In Ground or Base Plated Posts or onto Spacer Blocks mounted upon Posts dependent upon the relevant standard. In a non-standard application Thrie-beam may be mounted directly onto any suitable structure.Features FeaturesFeatures• Crash tested and approved to NCHRP-350 TL3• Accepted by the Austroads Safety Barrier Assessment Panel (ASBAP)• Designed in accordance with AS/NZS 3845.1:2015 or AS/NZS 3845.2:2017 Road Safety Barrier Systems & Devices• Increased height and rigidity for reduced deflection and higher containment• Overlapping splice bolt connections for secure rail joining• Available in lengths up to 4m Net Lineal Length (NLL)• Suitable for installation with base-plated or in-ground posts, spacer blocks, and direct mounting
