Guardrail Barrier

INTRODUCTION

ADVANTAGES

Roadside barriers have been developed over the years to safely redirect vehicles that leave the roadway. Ingal are market leaders in guardrails and provide roadside barriers that are built to last. Many different rigid, semi-rigid and flexible designs for roadside barriers have now evolved. The most common system consists of a steel w-beam rail supported on steel posts with end treatments and transitions of various designs using similar materials.

The Ingal Civil Flexbeam guardrail’s uniform high resistance to impacts is assured by its continuous flexible beam action. This prevents dangerous pocketing and minimises the ride down deceleration that is experienced by the vehicle and its occupants.

The high visibility of the Flexbeam guardrail creates driver confidence. This is an intangible but exceedingly important factor. At night or in foggy conditions, the excellent visibility of the Ingal Civil Flexbeam guardrail highlights the limit of safe travel and reduces dangerous centreline crowding.
