- Description DescriptionFlexbeam W-Beam Rail is used in semi-rigid safety barriers in multiple applications and is integral to the safe & efficient redirection & containment of vehicles. WBeam 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 WBeam may be mounted directly onto any suitable structure.Description DescriptionFeatures• Ease of Connection: W-Beam Rails join by overlapping and use Splice Bolts which lock into pre punched slots. Rail lengths allow for this overlap and are sold by “Net Lineal Length’ which refers to the effective length when Rails overlap. As an example, a 4m NLL Rail is 4.320m Overall but has 160mm at each end which is consumed when joined to another rail.• Standard Lengths: W-Beam Rails are available in standard lengths of up to 5m NLL and are punched to suit Splice and Post connections at each end. Some lengths and specific applications are available with additional Post slots.• Attachments: A range of connections to suit non roadside installations is available including Base Plated & In Ground Posts, Fishtail & Short Bullnose ends and, 45 & 90 Degree corners.Description DescriptionAcceptanceFlexbeam W-Beam guardrail is ‘deemed to comply’ with NCHRP-350 Test Level 3. For MASH-compliant systems, refer to the Ezy-Guard family of products.Description DescriptionPreformance MetricsNCHRP-350 Compliant: Flexbeam W-Beam is compliant with NCHRP-350 Test Level 3 standards for semi-rigid roadside barriers.State Compliance: Flexbeam W-Beam meets jurisdictional requirements across multiple Australian states, with specific configurations for each.
