Guardrail end terminals are designed to provide a soft gating impact to prevent the end rail from spearing an impacting vehicle. Terminals also introduce tensile and flexural strength necessary to ensure redirection performance of the length-of-need section.

Depending on the guardrail design, the guardrail end is generally divided into the following types: Fishtail End,Buffer End,Bullnose End,Anchor End,Bridge End,SKT End, etc.
