NCHRP-350 FLEAT End Terminal Info Hub

Steel guardrail systems are the world’s most widely specified type of safety barrier system and have significantly contributed to improving the safety of our roads.

The use of end terminals is an important characteristic in the function of the guardrail system.

Safe Direction manufacture and distribute a variety of end terminals for guardrail systems, catering to a diverse range of application sites.

The Flared Energy Absorbing Terminal (FLEAT) guardrail end terminal is designed for direct attachment to W-beam guardrail to minimise the severity of impacts occurring at the end of the safety barrier system.

FLEAT End Terminals are the specially designed end pieces located at the leading and trailing end of the guardrail system.

The strength of a steel guardrail system is primarily developed through a combination of the flexural resistance of the rail and the bending resistance of the supporting posts.

The FLEAT is fully compliant with the requirements of NCHRP Report 350 (MASH Test level 2) and is one of the world’s leading end treatment solutions.

How do FLEAT-End Terminals work?

The FLEAT End Terminal combines the superior performance of the energy absorbing tangent terminals with the advantage of flared terminals, to reduce vehicle impact severity upon collision.

FLEAT End Terminals anchor the steel guardrail system and introduce the necessary tensile and flexural strength required for safe vehicle containment and re-direction throughout the length-of-need section.

When struck head-on, the FLEAT head slides over the W-Beam guardrail. The guardrail is sequentially kinked as it gradually moves through the head. The kinked guardrail proceeds to safely exit the head slowly, bringing the vehicle to a controlled stop.

In situations where the impact occurs along the side within the length-of-need, the FLEAT functions like a guardrail, safely re-directing the errant vehicle back towards its original travel path.

Features and Benefits

  • The configuration of FLEAT End Terminals only requires 7 posts and has fewer small components than any other flared terminal, substantially reducing installation and maintenance time.
  • The straight flare design feature allows the FLEAT to be installed at a variable offset from 760mm to 1220mm on both wood and steel posts, making it a suitable option for a variety of application sites.
  • The straight profile of the flare serves to simplify the installation process and improve the terminal’s performance in traffic face re-direction impacts.
  • The flare can also be optimised to fit the site conditions, minimising the need for expensive site grading.
  • Unlike non-energy absorbing terminals, the FLEAT enables the kinetic energy to be absorbed when struck head-on, bringing the vehicle to a halt and containing it within the parameters of the terminals. This prevents the vehicle from travelling a great distance beyond the terminal, alleviating the possibility of further damage.

All FLEAT End Terminals that are distributed by Safe Direction undergo full scale crash testing and are fully compliant with both local and international industry standards.
