Utilizing the deformation of soil bases, pillars, and crossbeams to absorb collision energy, and forcing out-of-control vehicles to change direction back to the normal travel path, preventing them from veering off the road to protect both vehicles and passengers, and reduce the losses caused by accidents. The corrugated beam guardrail combines rigidity and flexibility, offering strong collision energy absorption and collision prevention capabilities, along with good visibility guidance functions. It can coordinate with the road alignment, has an aesthetically pleasing appearance, can be used on tight-radius curves, and damaged sections are easy to replace. The combined corrugated beam guardrail can be used on narrow central dividers. For sections where vehicles may veer off the road (bridge) and cause severe consequences, reinforced corrugated beam guardrails can be chosen.
