T-39 Thrie-beam is a fully crash tested system complying to NCHRP 350 Test Level 3 & Test Level 4. Steel Yielding Line posts replace the traditional “C” Post design used in the G9 Thrie-beam system, thus eliminating the need for a blocking piece. The Rail is spliced midspan, minimising the risk of rail rupture and ensuring superior performance and reliability.
T-39 Thriebeam is a narrow barrier that can be used in median applications with the Thrie-beam on both sides of the post.
