The Function and Design Conditions of W Beam Guardrail

1. Introduction of W beam guardrail

In recent years, the significance of W beam guardrail has become increasingly recognized. This type of guardrail is an integrated, corrugated, and movable steel barrier located at the center separation of highways. It consists of two corrugated steel panels and two vertical posts that securely hold them in place.

2. The role of W beam guardrail

In areas experiencing economic growth, the density of villages and towns adjacent to highways has risen. This leads to an increase in road crossings, necessitating heightened embankments, which subsequently elevates the risks associated with highway slopes. Furthermore, the limited width of central partitions, curbs, and shoulders emphasizes the necessity for highway metal guardrails.

Installing W beam guardrails effectively prevents out-of-control vehicles from veering off the roadway and crashing into roadside objects. Additionally, these barriers stop other items from intruding into traffic lanes through the central partition, thereby reducing the likelihood of traffic accidents. They also aid in guiding vehicles back into their intended driving paths, minimizing passenger injuries and enhancing visibility for drivers.

3. Design conditions of W beam guardrail

W beam guardrails can be classified into flexible, semi-rigid, and rigid categories. They possess a certain degree of flexibility, which allows them to absorb collision energy and mitigate the effects of crashes through beam deformation. Moreover, these guardrails provide excellent line-of-sight guidance, seamlessly aligning with road configurations. They can be installed in areas with tight curvature, where they maintain an aesthetically pleasing appearance, and damaged sections can be replaced with ease.

This hot-dip galvanized steel W beam is one of the highway safety products from DACHU that complies with AASHTO and ASTM specifications.

Hot-dip Galvanized Steel W Beam

Hot-dip galvanized steel W beam enjoys great popularity in current construction projects. This product offers superior corrosion resistance, weather protection, and resilience to abrasion, making it exceptionally suitable for outdoor applications. The hot-dip galvanizing process creates a robust bond between the metal alloy and a zinc coating, significantly enhancing durability and corrosion resistance compared to alternative materials. Available in various sizes, hot-dip galvanized steel W beams are perfect for highway guardrails, farm fencing, and several other outdoor structural needs.

This hot-dip galvanized steel W beam serves as a road barrier, ensuring highway safety by preventing errant vehicles from leaving the road and colliding with nearby structures or objects. Consequently, these guardrails are primarily installed along highways, docks, and narrow paths particularly in curves and slopes to offer protection against off-road accidents.

Advantage of Hot-dip Galvanized Steel W Beam

DACHU rail sections can be installed on curves with radii ranging from 5 feet (1.5 m) to 150 feet (45.7 m), and we can shape them in our production facilities prior to shipment.

Hot-dip galvanized steel W beam guardrails can be curved either outward (convex) or inward (concave) as required, which adds flexibility in design.

Applications of Hot-dip Galvanized Steel W Beam

Acting as a highway guardrail, hot-dip galvanized steel W beams are utilized to block off fields or create a safe area for drivers in the event of an accident. Usually combined with other highway guardrails, these beams provide additional stability and support. They are also favored for farm fencing, as the zinc coating assures long-lasting protection for the entire structure. Moreover, these solutions enhance security and add an attractive aesthetic element to rural properties.
