Highway rolling guardrail high-speed rotating guardrails road new anti-impact roller guardrails EVA foam roller barrels
The base metal materials used for the columns, beams, gyroscopic rings, ends, and column caps of the rotating cylinder guardrail are
For carbon structural steel, its mechanical performance index is not lower than the requirements of Q235 grade steel stipulated in GB/T700
beg. The base metal material used for bolts, nuts, etc. is carbon structural steel, and its tensile strength is not less than
375N/mm2. The reflective strip should use a first-class reflective film as the retroreflective material, and the material should be soft
Non-toxic materials, other properties should meet the requirements of GB/T18833 and JT/T388.
1. Adopt high-quality original material
Roller EVA material with elastic characteristics is used as raw material, which can slow down the lateral impact process of the out-of-control vehicle. Moreover, the rotating barrel can rotate around the column under a certain impact, driving the out-of-control vehicle to return to the correct driving direction.
2. High quality steel support
Using Q235 steel, multiple thick steel fixed, durable, strong protection ability.
3. Strong of lower solid frame
The round post could buried deep, structural strengthening, can effectively block the front or side impact.
1. The anti-collision pad under the wire rope safety fence on the side of the road is used to protect the safety of people and reduce the impact in the event of a traffic accident.
2. The anti-collision barrel can play the role of isolation warning and anti-collision because of its bright color.
3. It can buffer the accidental collision with the vehicle, effectively reduce the impact force, and greatly reduce the damage of the vehicle and people.
1. Heat-resistant, cold-resistant, impact-resistant, not easy to age.
2. The polyurethane material is bright and bright in color, and the red and white reflective film is more eye-catching at night with various colors. Polyurethane is a new polymer synthetic material between rubber and plastic. It has both the high strength of plastic and the high elasticity of rubber.
