T-31 Guardrail

The T-39 Guardrail™ is a strong post Thrie-beam system that has been successfully crash-tested with the heavier pickup truck detailed by the FHWA proposed NCHRP “350 update” criteria, as well as to NCHRP Report 350 Test Level 4. In the 39” system height, the Thrie-beam attaches directly to Steel Yielding Line Posts™ (SYLP™) eliminating the need for off-set blocks.

Features:

  • Strong posts with weakening holes at the ground line.
  • No offset blocks required.
  • Countersunk-Head Bolts and Flange Protectors.
  • Mid-span splices between adjacent posts.
  • NCHRP Report 350 Test Level 4 compliant.
  • Successfully crash tested with the heavier pickup truck of the FHWA proposed “350 update” criteria.
  • Reduced site grading by eliminating spacer block.
  • Single-Face or Double-Face (median) application.
