Product description

The guardrail board uses the deformation of soil foundation, column, beam and endurance board to absorb the collision energy, and force the out-of-control vehicle to change direction and return to the normal driving direction to prevent the vehicle from rushing out of the road, so as to protect the vehicle and passengers and reduce the accident caused by Loss.

The highway corrugated guardrail is the main form of semi-rigid guardrail. It is a continuous structure with corrugated steel guardrails spliced with each other and supported by columns. The steel is flexible and has a strong ability to absorb collision energy. Good sight-guiding function, can coordinate with the road alignment, beautiful appearance, can be used on small-radius curves, and the damaged part is easy to replace.

According to the anti-collision grade, the highway wave guardrail can be divided into A grade and S grade. The S-level guardrail is a reinforced type, which is suitable for use in particularly dangerous road sections on the roadside, and the A-level guardrail is used for special roads. The commonly used roadside corrugated beam guardrails can be divided into five grades: B, A, SB, SA, and SS according to the anti-collision level.
