On any given stretch of a road, in certain areas, the roadway may have steep embankments or side-slopes next to it, or even be lined with trees. Utility poles, bridge piers and retaining walls are other obstacles where guardrails are installed. They help lessen the severity of a potential crash and make the roads safer.

The guardrail acts in many different ways from deflecting a vehicle back onto the road, to slowing it down, to stopping the vehicle, or in some cases just slowing it down enough and allowing the vehicle to progress past the guardrail.

Rowser Construction works on every type of road to ensure that their roadside safety equipment becomes the last defense in keeping Americans safe.
