Thrie-beam Guardrail

Product description

Thrie-beam Guardrail 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.

Thrie-beam Guardrail 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 Thrie-beam Guardrail 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 is semi-rigid guardrail?

    Is our common wave guardrail products, it uses the column, anti-block, screws and other components connected together, at the moment of vehicle impact, the use of the deformation of each component to absorb energy, so as to force the vehicle to change the driving reverse, to avoid rushing out of the road or running to the opposite lane caused by secondary accidents, to the greatest extent to protect the safety of drivers and passengers.

    In practical applications, the above three guardrail should be the most safe and effective semi-rigid guardrail. Also the most common! The reason is that according to the momentum theorem, Ft is equal to mv. Rigid guardrail, the action time is short, so when the total momentum is certain, the force is large. The semi-rigid guardrail allows a certain deformation, and the deformation process takes a long time, making the impactor less stressed and less damaged.
