Metal Corrugated Beam Highway Barrier

Product description

Metal Corrugated Beam Highway Barrier is the main structure of the semi-rigid guardrail, which is an uninterrupted shape composed of corrugated metal guardrail plates, connected and supported by the post.

Metal Corrugated Beam Highway Barrier uses the deformation of the foundation, post and beam to absorb the force of the collision and control the pressure generated by the vehicle, so that Metal Corrugated Beam Highway Barrier can change the direction and return the vehicle to the normal direction of travel, protect the vehicle and passengers, and reduce the loss caused by accidents.

What are flexible guardrail and rigid guardrail?

1. Flexible guardrail. Its main form is cable guardrail, cable guardrail by the column, bracket, cable, fixtures, anchors and other components. It is a structure composed of several cables with initial tension fixed on the column, which mainly relies on the tension stress of the cable to resist the collision of the vehicle and absorb the collision energy. However, the construction of cable guardrail is complicated, the end column is damaged and difficult to repair, and it is not suitable for use in small radius curve sections; At the same time, its sight inductance is poor, and the erection length is not economical for a short time.

2. Rigid guardrail. Rigid guardrail generally establishes a middle isolation belt, this guardrail rigidity is large, the collision is not easy to deform, so the object after the collision will not easily run to the other side of the guardrail to cause a more dangerous accident. However, when the rigid guardrail is collided, the action time is short, the deformation is small, and the impact force caused by the collision body is large, which is easy to cause its own injury. However, in some places that are necessarily not allowed to cross the boundary, the use of rigid guardrail is a necessity, otherwise the consequences of secondary collisions and injuries are more serious.
