What are the factors that cause damage to highway guardrails?
Highway guardrails are a common and important facility on highways, which can reduce the losses caused by accidents and protect the safety of passengers in case of accidents.
So, the maintenance and replacement of guardrails is also an extremely important task. So, what are the reasons for the damage of highway guardrails?
There are two main reasons for the damage of highway guardrails:
Natural factors
The highway guardrail panels are installed on both sides of the road and are subjected to harsh weather conditions, resulting in varying degrees of damage and oxidation rust on the surface of the guardrail panels. When the guardrail board rusts, it accelerates the rate of secondary oxidation, greatly reducing the service life of the guardrail board.
Human factors
When a vehicle collides with it, due to the excellent collision resistance and energy absorption of the corrugated steel guardrail on the highway, it is not easily damaged and can provide good protection for the vehicle and passengers. When road maintenance or other reasons require merging, it is convenient to pull out and remove the various guardrail columns at the opening to open a passage for vehicle traffic. Guardrail boards not only protect the safety of vehicles and personnel, but also cause corresponding damage to highway guardrails.
Therefore, after the installation of the guardrail board on the road, regular maintenance and repair should be carried out to effectively ensure the extension of the guardrail board's service life.

Factors to be considered in the design of road guardrails
Nowadays, the design of road guardrails is also very particular. So, what factors should we consider in the design? Today, we will talk about the factors that need to be considered in the design of road guardrails. We hope our introduction can be helpful for everyone in their future lives. Let's take a closer look at this information. Let's take a look together!
What factors should be considered in the design of road guardrails?
（1） Galvanized design: As we all know, road guardrails are coated with a layer of zinc, which not only provides protection but also extends the service life of the guardrail. The durable coating of galvanized design consists of hot-dip zinc layer, zinc rich phosphating layer, organic zinc rich epoxy powder coating, and polyester "flawless" color powder coating. It requires good surface treatment technology and advanced specialized equipment to scientifically and reasonably combine the four protective layers, endowing municipal guardrails with excellent corrosion resistance, good moisture resistance, chemical resistance, and strong UV stability.
（2） Color function design: In fact, the color elements of road guardrails are also very important. In order to meet the needs of traffic safety and smooth roads, green is changed from green to blue on the basis of current traffic colors of red, white, yellow, green, and black, forming five basic colors of red, blue, white, yellow, and black. Various combination colors related to direction, driving rules, and warnings are designed and configured on municipal traffic guardrails to enrich the concise and clear characteristics of urban traffic language, which can be easily understood at a glance.
