W-beam guardrail is a widely used in highway safety protection facilities, mainly used to separate the driveway and protect the safety of drivers and passengers. It is designed to mitigate injuries to occupants in the event of a collision, while preventing the vehicle from leaving the road or bumping into other obstacles. Because of its excellent safety performance and economy, the corrugated guardrail has become an important part of the modern highway construction.
W-beam guardrail usually consists of W-beam steel plate, column, connector and foundation parts. Its waveform design not only enhances the strength of the guardrail, but also effectively distributes the impact force generated by the collision. Common W-beam guardrail has two wave and three wave design, the number and depth of W-beam directly affect the impact resistance of the guardrail.

W-beam guardrail is mainly used in expressway, urban main road, rural road and other occasions. They are used not only for lane separation, but also for the protection of sidewalks and bike lanes. In addition, the corrugated guardrail in specific areas, such as Bridges, tunnels and other special sections, has also played an important role in safety protection.
The maintenance and management of the waveform guardrail is equally important. Regular inspection of the integrity of the guardrail, corrosion and the tightening state of the connections are the key to ensure its safety performance. If necessary, the damaged part should be replaced in time to ensure the effectiveness and durability of the guardrail.
Conclusion
Highway W-beam guardrail has become an important facility of modern traffic safety with its excellent safety performance, economy and durability. Reasonable design and standard maintenance can effectively reduce the risk of traffic accidents and ensure the safety of road users.
