Product Description
Safety double barrel guardrail highway roller barriers for tunnel entrance
Safety roller barrier is a fixture that prevent drivers and passengers from fatal accidents by not only absorbing shock energy but also converting shock energy into rotational energy.It is designed to effectively absorb shock and lead vehicle to the road direction to prevent large accidents. It can also called roller barrier, rolling barrier, roller type barrier, drum barrier or highway roller, and widely used on sharp carve road or bend road zone.
Safety roller is a fixture that prevent drivers and passengers from fatal accidents by not only absorbing shock energy but also converting shock energy into rotational energy. It is designed to effectively absorb shock and lead vehicle running back to the road direction to prevent large accidents at bend or carve road sites. Safety roller will effectively function for drivers to properly control vehicles with its noticeable color and self-luminescence.

Features of roller barrier
1. Reduce speed by stopper board
2. Guide reflective leads a driver to drive safely
3. Recyclable material (eco-friendly)
4. Help a vehicle turn back to the road by its spinning when the car crashed the rollers laterally
5. Minimize fatal damage of people and vehicles by absorbing collision shock
6. Reduce costs in repairing and maintenance due to Roller’s resilience.
7. Stopper boards help prevent larger accidents by slowing down Roller’s spin
8. Can be used for many years, less cost.
