Highway Use Rolling Road Safety Highway Roller Barrier System Highway Guardrail/Safety Rolling Barrier

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.

They consist of both flexible property and semi rigid property of barrier stiffness. RB are different in mechanisms than the other types of normal barriers. It also reduces the hazard and road accidents.

Urethane has become the material of choice in so many of today’s performance driven applications because it illustrate extraordinary physical and mechanical properties that other material simply can’t match.

Roller Barriers absorbing the collision shock in three points, the barrel, the buffering bracket, and the liquidity of the rail shocking mechanism. The shock energy absorb from a curved crash is absorbs then the shock is converting in a rotational energy. Shock energy absorbs the gain by its upper and lower safety guard rail. Shock energy will be again by the back side of safety rails.

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.
