<p>A method of joining rails to facilitate absorbing energy and telescoping of rails 7 in a guardrail or other energy absorbing apparatus 100, comprises the step of progressively increasing the relative joint strength for respective downstream joints connecting adjacent rails to one another starting from a first joint downstream of an impact slider assembly 5 in order to control the order in which the subsequently downstream joints fail following an impact and during telescoping movement of the rails.</p> |
