The starting point of the guardrail or barrier is referred to as the end terminal or treatment. The exposed end of the guardrail needs to be treated to prevent it spearing or flipping vehicles.
If you are working with an enter terminal but not sure which one, check out this guide.
These end terminals function in two ways.
Non-Redirective/Attenuating/Energy Absorbing - The impact head slides down the guardrail flattening, ripping, or extruding the guardrail and redirecting the guardrail away from the vehicle until the vehicle's impact energy is dissipated and the vehicle has decelerated to a stop.
Redirective/Gating/Non-Energy Absorbing - The impact head "gates" out of the way allowing the vehicle to pass behind the guardrail. This means the terminal and guardrail is pushed through, as if opening a gate.
Some terminals are discretely gating while others are both gating and attenuating depending on the angle of impact.
Our device list is compiled from a number of industry guides and summaries described on our sources page. Different versions of the same product (including MASH versions and median terminals) are given as versions on the product page.
