T-39

The T-39 Thriebeam Barrier is the latest innovation in steel safety barrier systems providing superior design, rapid installation and driver confidence. The T-39 barrier has been fully crash tested and evaluated according to specifications for Test Level 3 (TL3) and Test Level 4 (TL4) of the US National Cooperative Highway Research Program Report 350 (NCHRP Report 350) and the anticipated update to NCHRP Report 350.

Traditional ‘deemed to comply’ C posts have been replaced with specially engineered Steel Yielding Line Posts (SYLP’s) in order to prevent vehicle snagging, thus eliminating the requirement for blocking pieces. This, together with rail splices located mid-span between posts, results in reduced working widths, an easier to install system and a fully compliant NCHRP Report 350 safety barrier.
