HammerBeam™ Bridge & Culvert Barrier

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.
