How safety roller barrier works?
1. The roller barrier converts great shock from vehicle collision to rotational energy to absorb shock.
2. Upper and lower frames adjust tires of large and small vehicles to prevent the steering system function loss.
3. The three-dimensional structure of D-shaped frame and buffering bracket distribute and absorb the 2nd shock.
4. Props at an interval of 0.7 m increase bearing power to prevent accident vehicles from going over the guardrail and turning over into a dangerous area.
5. The product has a rotating barrel made of EVA with excellent shock absorption power, three-dimensional buffering frames and dense props supporting the frames.
Ethylene Vinyl Acetate Copolymer Metal Beam Crash Barrier Roller Safety Barrier Box Beam Guardrail
As a new type of guardrail, the rotating tunnel entrance guardrail has been used in recent years. The main component of the rotating barrel is a flexible material made of polyethylene and EVA (ethylene vinyl acetate copolymer), which can be used as a longitudinal energy-absorbing structure. In the process of collision between the vehicle and the guardrail, the rotating barrel can drive the vehicle through its own rotation, reducing the collision angle between the vehicle and the guardrail, thus reducing the lateral force generated in the process of impact. The rotating guardrail turns the sliding friction between the normal guardrail and the vehicle into a smaller rolling friction. The rotating tunnel entrance guardrail not only reduces the acceleration of each component of the collision vehicle, reducing the injury to personnel and reducing the degree of vehicle deformation, but also reduces the collision time and increases the vehicle exit speed. In addition, it reduces the vehicle's handling resistance in a collision, helping the driver to operate the vehicle quickly away from the guardrail to complete the guidance. Rotating guardrail in the collision barrel colour setting can be customized according to the needs of red, yellow or other colours, to form a visual impact on the driver, with excellent guidance function.

|Grade two highway||48||10|
|Level 3 and 4 Highways||28||5|
The rotating guardrail is mainly composed of column, swing circle, rotating barrel, cross beam, waveform beam, reflective strip and corresponding connecting parts. The rotating barrel is made of a composite material of ethylene vinyl acetate copolymer (EVA) and polyurethane, which is elastic, impact resistant and wear resistant and can effectively prevent the rotating barrel from being shattered upon impact. The resilience of the barrel also ensures that it can be quickly restored to its original state after a severe impact. The barrel chosen by Suzhou Bypass Expressway Co., Ltd. is orange, which has a high brightness reflection effect and eye catching function, which can effectively improve the driver's attention and reduce the incidence of accidents, thus ensuring the safety of vehicles.
(1) Fast opening.
The pluggable and removable structure enables 12 m (2 sections) to be opened and pushed in 3 minutes in case of emergency, far better than the norm of 10 m in 10 minutes.
(2) Safety upgrade.
Through rotational friction, the instantaneous impact energy is transformed into rotational energy and friction energy, effectively reducing the damage to the vehicle and the degree of injury to personnel.
(3) Material saving.
The simple shape of the product greatly saves material costs, using about 78 kg of material per linear metre, which is 50% to 80% of the material used in similar products in the current market.
(4) Beautiful shape.
The beautiful shape and beautiful rotating barrels have a good sight line guidance function, which can improve the road appearance and effectively ease the
The effect is more obvious especially at night and in rainy days.
(5) Easy to install.
The compact design of the product allows for easy installation on site after the unit has been assembled, greatly reducing the time spent on site and effectively reducing the risk of road-related operations.
(6) Simple maintenance.
The rotating bucket is made of EVA composite material, which is resistant to chemical corrosion, ageing and weathering, and is not easily damaged by vehicle impact, and does not need to be replaced during its service life (10 years).
