However, they differ in structure, impact performance, cost, maintenance, and suitable applications. This guide compares rolling barriers vs steel guardrails to help you choose the right roadside safety system. What is a Rolling Barrier? A rolling barrier, also known as a roller barrier or rolling guardrail, is a roadside safety system that uses rotating cylindrical rollers mounted between steel posts. When a vehicle hits the barrier, the rollers rotate and help convert part of the impact energy into rotational energy. Instead of simply stopping the vehicle, the system is designed to guide it back toward the roadway while reducing the severity of the collision. A typical rolling barrier system includes: Because of its distinctive yellow or orange rollers, the barrier can also provide good visual guidance, especially on curves and at night. What is a Steel Guardrail? A steel guardrail is a conventional roadside restraint ..."}
