Highway guardrail is a continuous structure made of corrugated steel guardrail plates made of galvanized steel plate splicing each other and supported by the main column, and its surface is covered with a layer of anti-rust paint to ensure its long-term use. When the vehicle collides with it, the waveform design of the corrugated guardrail can provide greater energy absorption, reduce the impact force of the vehicle in the collision, and thus reduce the severity of the accident. The design of highway guardrail plate must follow the efficient and scientific concept, provide protection for people's safe travel, and strive to prevent traffic accidents。High-speed guardrail engineering mainly includes guardrail , guardrail post, guardrail spacers and other accessories.

In order to improve the safety of the guardrail, the standards of the highway guardrail are as follows:

1. Guardrail height: the height of the highway guardrail should not be less than 70cm to ensure the safety of the vehicle.

2. Guardrail column: guardrail column should be solid and reliable, the diameter is not less than 130mm, the spacing is not more than 4m, and the buried depth under the column is not less than 60cm.

3. Guardrail plate: guardrail plate should be solid and durable, thickness is not less than 3.0mm, width is not less than 310mm, length is not less than 4320mm.

4.Guardrail connectors: guardrail connectors should be solid and reliable, and unqualified connectors should not be used to ensure the firmness and stability of the guardrail.

5. Guardrail color: The color of the highway guardrail should be eye-catching yellow or white, so that the driver is easier to identify and alert when driving.

6. According to different road needs, we can choose different guardrail plate shapes, expressway choose three-wave guardrail, the rest of the low-speed road choose double-wave guardrail.
