The structure and characteristics of highway guardrail

Structurally, highway guardrail is usually made of steel plates that have been stamped and then hot-dip galvanized or sprayed with plastic. The highway guardrail treated in this way not only has excellent anti-corrosion performance and can be used for a long time in harsh environments such as outdoor, low temperature, and acid rain, but also has a smooth and bright surface, with excellent aesthetics. At the same time, the combination design of the curvature of the highway guardrail and the anti blocking block can effectively reduce the huge kinetic energy of the car, with a high collision coefficient.

The installation locations of highway guardrail are mainly divided into roadside guardrails and central median guardrails. On highways, the main form of guardrail panels is semi-steel guardrails, which are connected by corrugated steel highway guardrail and supported by columns. They have the characteristics of both steel and flexibility, effectively absorbing collision energy and having good line of sight guidance function. They have a beautiful appearance and are easy to use on small radius bends. In addition, once damaged, the damaged part is also easy to replace.
