2. Product Introduction
| Product Name | Roller barrier |
| Material | Polyurethane, hot galvanized steel |
| Color | Yellow, Orange, As you required |
| Used | Highway, tunnel, bridge |
| Features | Anti-corrosion, high tempreture resistance, low friction |
The rotating guardrail combines the advantages of traditional barrier and new type energy -absorption anti-collision roller barrel. It inserts the anti-collision roller barrel into strengthened traditional barrier. When traffic accident happening, the roller barrel can rotate freely on the columns, and through this free rotation of the roller, they break down the impact force of the car. it can efficiently resolve the impact energy by converting the impact energy to rotational energy and pull the accident car back to normal motion trail.
