What material is highway guardrail made of?
Expressways are important traffic arteries connecting various cities. To ensure the safety and smoothness of the roads, they must be equipped with complete traffic safety facilities, one of which is guardrails. So, what materials are highway guardrails made of?
During the specific construction process, there are many kinds of materials used for highway guardrails. Common ones include steel, aluminum, galvanized steel pipes, plastics, etc. Different materials have unique characteristics and usage scenarios:
Steel guardrails: Steel guardrails are widely used in highways and other places because of their high strength and toughness. It has the characteristics of impact resistance, good stability, anti-corrosion, and durability, but it has a certain impact on the reflectance of the road surface.
Aluminum guardrail: Aluminum guardrail has the characteristics of good toughness and beautiful appearance, but its strength is slightly insufficient compared to steel.
Galvanized steel pipe guardrail: Because of its beautiful appearance and low value, galvanized steel pipe guardrail is often used in some road sections that do not require high guardrail strength. However, because it is tubular, it does not have the strength of sheet guardrails.
Plastic guardrails: Plastic guardrails are usually made of polyurethane, polypropylene, and other materials. The unique plastic material makes it lightweight, not easy to rot, not easy to age, etc. However, due to its relatively low toughness and strength, it is often used in road sections where the vehicle speed is slow and the risk factor is not high.
