In rainy, snowy and foggy weather, the high-speed guardrail can give the driver the correct direction because of the reflective effect, ensuring that he has a clear direction. When purchasing guardrails, you need to determine what protection level is required, or directly tell the manufacturer where to install them, such as: the middle of the village road, the highway isolation zone, the sides of the highway, etc., the guardrail manufacturer will clearly give Specifications for guardrail requirements.
Guardrails are divided into five levels: B, A, SB, SA, and SS. The middle-level guardrails mainly differ in the waveform and material of the guardrails. In terms of protection effect, it can also be divided into two-wave guardrails, three-wave guardrails, and two-wave three-wave transition boards.
The protection of guardrails is inseparable from the expressway. Many people think that the guardrails are the same. In fact, there are differences in the guardrails in different road sections. So what kind of guardrail should be selected for which road section? Collisions are generally more likely to occur on turning road sections. When the vehicle is turning, it is easy to rush out of the expressway due to poor speed control. Therefore, it is necessary to install a guardrail with a higher protection level at the corner.
