The typical steel plate guardrail does not guarantee the safety of the driver. Softer guardrails can protect drivers from impact and provide an opportunity to save more drivers' lives. In order to minimize accidents, rotating guardrail was born. Rolling barriers do more than absorb impact energy. They convert impact energy into rotational energy to propel the vehicle forward, rather than potentially breaking through immovable obstacles. The Taicheng product features a rotating EVA barrel with excellent shock absorption, a three-dimensional cushioning frame and dense props to support the frame. The rotating barrel is equipped with a reflector to provide good visibility. Compared to other polyethylene resins, EVA has better flexibility and elasticity and has the most similar properties to rubber. In fact, it is lighter than rubber and more flexible than polyurethane. In short, it is not easily damaged.

Advantages:
Energy absorption: The roller guardrail is designed to gradually absorb the kinetic energy of the collision vehicle, reducing the severity of the collision. The rolling motion of the barrel dissipates energy over longer distances, reducing the decelerating force on the vehicle and its occupants.
Direction control: When the vehicle hits the roller guardrail, the roller spins, which helps to redirect the vehicle back onto the road, preventing it from crossing oncoming traffic or colliding with stationary objects such as trees or power poles.
Versatility: Roller guardrails can be used in a variety of road and highway configurations, including straight sections, curves, and Bridges. They can also be installed in permanent and temporary environments.
Reduced maintenance: Roller guardrail maintenance costs are generally lower because the roller spins when hit, minimizing damage to the guardrail itself. This can save costs over time compared to traditional rigid barriers that may require frequent servicing or replacement.
Improved safety: Roller guardrails are designed to enhance road safety by reducing the severity of collisions and preventing vehicles from leaving the road. They are often used in areas with a high risk of off-road accidents.
Compatibility: Roller guardrail is compatible with other safety measures and technologies, such as guardrail, crash cushioning and electronic warning systems.
It is important to note that roller guardrail is only one type of road safety guardrail system, and its effectiveness depends on a number of factors, including proper installation, maintenance, and compliance with safety standards and guidelines. Different regions and countries may have their own specifications and guidelines for the use of roller guardrails in road safety applications.

The rotary drum is made of EVA (ethylene-vinyl acetate copolymer) as the main material, and more than 30 kinds of auxiliary materials such as PE (polyethylene) and related chemical auxiliaries are added at a certain temperature and pressure. It has high flexibility and resilience, and also has high temperature resistance, and continuous working temperature is between -30℃ and 70℃.
The reflective strip is attached to the rotating cylinder. When driving at night, through the lighting of the headlights, the outline of the route can be better reflected, and the vehicle can play a better induction role to improve driving safety.
