Common materials used in the processing of highway guardrail

The most common materials used in highway guardrail processing are steel, aluminum alloy, and galvanized steel plate.

Steel plays an important role in the manufacturing of highway guardrail due to its high strength and durability. It can effectively prevent vehicle collisions and has good anti-corrosion performance, which can extend the service life of guardrails.

Aluminum alloy is another common material that is highly favored due to its lightweight, high strength, and excellent corrosion resistance. Aluminum alloy highway guardrail is particularly suitable for humid, long rainy seasons, or harsh environments such as the seaside. In addition, aluminum alloy guardrails have a beautiful appearance, high glossiness, and long service life.

Galvanized steel plate is a material that adheres a zinc layer to the steel plate through galvanizing treatment, which has strong corrosion resistance and is not easy to rust. In the humid environment of highways, highway guardrail made of galvanized steel plates can effectively resist corrosion.
