Hammerbeam™ combines the strength of thrie-beam guardrail with the yielding behaviour of the RamShield® W-Beam post for longitudinal barrier installations along the edge of elevated structures such as culverts or bridges.

The RamShield® post is designed to collapse upon impact distinguishing it from heavier, rigid post systems which become problematic when attached to concrete structures. The yielding performance of the RamShield® post reduces forces transferred to the elevated structure preventing damage and facilitating ease of repair.

• Complies with MASH TL3
• Complies with AS/NZS 3845.1 Road Safety Barrier Systems & Devices
• Available with side mount or baseplate posts
• Side mounting aligns the face of the Thrie-beam rail with the edge of the elevated structure maximising usable bridge and culvert width
• Simple replacement of posts following design impacts
• Use of standard components eliminates the requirement for bespoke designs
• Narrow width: just 180mm
• Standard post spacing: 2m centres
