Waveguide guardrails are a common road safety facility, made of steel, such as Q235 ordinary carbon structural steel. They are named for their wavy shape, which provides excellent impact resistance and energy absorption due to their unique design.When a vehicle collides, the wavy guardrail absorbs the impact energy by utilizing the deformation of the soil base, posts, and beams, forcing the out-of-control vehicle to change direction back to the normal driving path, reducing accident losses, and ensuring the safety of the vehicle and passengers. It boasts excellent corrosion resistance, commonly treated with hot-dip galvanizing, and maintains stable performance in various harsh environments, with resistance to aging and corrosion. Additionally, the wavy guardrail offers good visibility guidance, coordinates with the road alignment, has an aesthetically pleasing appearance, can be used on tight-radius curves, is easy to install, and damaged sections are also easy to replace. It is widely used in places like expressways, urban roads, bridges, and more, providing a reliable guarantee for traffic safety.
