TREND® 350 Tangent

The TREND® 350 Tangent End Terminal is a single-sided, energy absorbing steel post terminal. It is tested to NCHRP Report 350 Test Level 3 as a redirective, gating end treatment.

The system can be used at the end of W-beam guardrail between 27 ¾” to 31″ assembly heights. While the TREND® 350 Tangent is primarily used with single-sided W-beam barriers, special transitions may allow for use with other barriers.

Product Inquiry Form


Upon frontal impacts within NCHRP Report 350 criteria, friction between the guardrail panels and deformation of the rail sections help absorb energy as they slide rearward over the adjoining panels. During side impacts within NCHRP Report 350 criteria, the yielding posts are designed to laterally support the rail sections so that the impacting vehicle can be redirected.
