Corrugated Beam Guardrail, also known as W-Beam Guardrail, is a type of safety barrier widely used in the United States for traffic management and protection. It is made of galvanized steel, which is then coated with a layer of plastic to enhance its durability and resistance to weather conditions.

One of the key advantages of Corrugated Beam Guardrail is its ability to absorb and dissipate impact energy in the event of a vehicle collision. The corrugated design provides a high level of strength and flexibility, allowing the guardrail to deform and absorb the impact force, thereby reducing the risk of injury to passengers.

The guardrail is available in various heights and lengths to suit different road conditions and requirements. Common heights include 2.5 feet and 4 feet, while lengths can range from 16 feet to 32 feet. The standard width of the guardrail is 10 inches, and it is typically installed with 4 to 6 inches of ground clearance.

There are several methods for installing Corrugated Beam Guardrail, including direct burial, concrete footing, and surface mounting. The choice of installation method depends on factors such as soil conditions, traffic volume, and available space.

This type of guardrail is commonly used in various applications, including highways, roads, bridges, and parking lots. It is particularly effective in areas with high traffic volumes or where there is a risk of vehicles leaving the road and colliding with obstacles or falling into ditches.

In summary, Corrugated Beam Guardrail is a versatile and effective safety barrier that offers numerous benefits, including impact absorption, durability, and adaptability to various road conditions and requirements.
