The Function and Design Conditions of W Beam Guardrail

1. Introduction of W beam guardrail

People pay more and more attention to the importance of W beam guardrail. W beam guardrail is a combined, corrugated and movable steel guardrail at the opening of the central separation belt of the highway. The guardrail is composed of two corrugated steel guardrail plates and two upright posts fixedly sandwiched between them.

2. The role of W beam guardrail

In economically developed areas, the villages and towns along the highway are relatively dense, and there are many passages crossing the main line, which means that the height of embankment should be increased and the danger of highway slope will increase. Besides the high embankment height and steep slope, the width of central partition, kerb and shoulder is also short, which requires the setting of highway metal guardrails.

W beam guardrail installation can not only prevent runaway vehicles from rushing out of roads and off-road obstacles, but also prevent other objects from rushing into lanes through the central partition to cause more traffic accidents. It can also restore the normal driving direction of vehicles, minimize the damage to passengers and induce the sight.

3. Design conditions of W beam guardrail

W beam guardrail is generally divided into flexible guardrail, semi-rigid guardrail and rigid guardrail. It has certian flexibility and can absorb collision energy and avoid collision through the deformation of the beam. In addition, it has a good line-of-sight induction function, which can be coordinated with road alignment. It can be used in small radius bends with beautiful and harmonious appearance. The damaged parts are easy to replace.

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

Hot-dip Galvanized Steel W Beam

Hot-dip galvanized steel W beam is one of the most popular metal beams used in construction projects today. This product provides excellent protection against corrosion, weathering, and abrasion, making it ideal for any outdoor project. Hot-dip galvanizing is a process used to create a bond between the metal alloy and a zinc coating, which not only increases the product&#;s durability and resistance to corrosion but also offers superior corrosion protection when compared to other materials. Hot-dip galvanized steel W beams are available in a wide range of sizes and are ideal for highway guardrails, farm fences, and many other outdoor structures.

This hot-dip galvanized steel W beam is a kind of road crash barrier used for securing highway safety by preventing errant vehicles from sliding out of the roads and impacting the roadside buildings or other objects. So it is most commonly fixed on the side of the highways, dock areas, aisles, especially on curves and slopes for protection against run-off-road collisions.

 

Advantage of Hot-dip Galvanized Steel W Beam

DACHU rail sections specified to be installed on curves having a radius of 5 feet (1.5 m) to 150 feet (45.7 m) can be curved in our fabrication facilities prior to delivery.

The Hot-dip Galvanized Steel W Beam guardrail can be curved either convex or concave as required. Terms convex or concave refer to the direction curved, outward or inward, relative to the traffic face of the rail.

Applications of Hot-dip Galvanized Steel W Beam

As a highway guardrail, hot-dip galvanized steel W beams are used to cut off fields, or provide a safe place for drivers to stop in the event of a collision. They are usually used in combination with other highway guardrails to provide additional support and strength. Hot-dip galvanized steel W beams are also popular for farm fencing, as the zinc coating offers long-term protection to the entire structure. Additionally, these products can provide added security and a valuable aesthetic boost to any rural property.
