What are highway guardrails made of?

Highway guardrails, also known as traffic barriers, are an important safety feature on roads and highways. They are designed to redirect vehicles that have left the road and prevent them from crashing into dangerous obstacles, such as trees or steep slopes. But have you ever wondered what these guardrails are made of? In this article, we will explore the materials commonly used to manufacture highway guardrails.

Steel

Steel is the most common material used in the production of highway guardrails. It is strong, durable, and can withstand extreme weather conditions. The steel used to make guardrails is typically galvanized, which means it is coated with a layer of zinc to protect it from corrosion. Galvanized Highway Guardrails are widely used in the United States and other countries because they have a long lifespan and require minimal maintenance.

W-beam Guardrails

W-beam guardrails are a type of highway guardrail that are made from galvanized steel. They consist of a series of W-shaped panels that are connected to form a continuous barrier. W-beam guardrails are designed to be flexible, so they can absorb the impact of a vehicle without breaking. This flexibility also makes them easy to install and modify, which is important when there are changes to the road layout or traffic patterns.

Thrie-beam Guardrails

Thrie-beam guardrails are another type of highway guardrail made from galvanized steel. They are similar to W-beam guardrails, but instead of a W-shape, they have a shape that resembles three waves in a row. Thrie-beam guardrails are often used in areas with heavy traffic or high speeds, such as highways and expressways.

Wood

Although steel is the most common material used in the manufacture of highway guardrails, wood is also sometimes used. Timber guardrails are strong and durable, and they have a natural aesthetic that can complement the surrounding environment. However, they require more maintenance than steel guardrails because they are vulnerable to decay and insect infestations.

Conclusion

In conclusion, highway guardrails are an essential component of road safety. They are designed to protect drivers and passengers from serious injury or death in the event of an accident. Steel is the most common material used in the production of highway guardrails, with galvanized steel being the most popular choice. W-beam and thrie-beam guardrails are two popular varieties of highway guardrail made from galvanized steel. Although wood is also used in the manufacture of some guardrails, it is less common because it requires more maintenance. If you have any questions about highway guardrails, please contact us.
