As an important part of traffic safety facilities, the quality and performance of corrugated guardrails are of great significance to ensure driving safety. However, the corrugated guardrail is often affected by various natural environments and human factors during use, resulting in rust and other problems on its surface, which not only affects the aesthetics of the corrugated guardrail, but also reduces its service life and safety. Therefore, it is particularly important to choose a corrugated guardrail that is not easy to rust.
In a variety of corrugated guardrail anti-corrosion processes, hot-dip galvanizing is an anti-corrosion treatment with good anti-rust performance. Hot-dip galvanizing is a process in which the steel material is immersed in molten zinc, so that the zinc and the surface of the steel undergo a chemical reaction to form a layer of zinc-iron alloy, which can effectively isolate the contact between the steel and the external environment, so as to play a role in rust prevention. Compared with other types of corrugated guardrails, hot-dip galvanized corrugated guardrails have the following advantages:
The anti-rust performance of hot-dip galvanized corrugated guardrail is better. Due to the hot-dip galvanizing process, the zinc-iron alloy layer has high corrosion resistance, which can effectively resist the erosion and damage caused by the natural environment and human factors, thereby prolonging the service life of the corrugated guardrail.
The hot-dip galvanized corrugated guardrail has good adhesion and wear resistance. The zinc-iron alloy layer formed by the hot-dip galvanizing process is tightly integrated with the surface of the steel, which is not easy to fall off and wear, and can maintain good appearance and performance even in harsh environments.
The hot-dip galvanized corrugated guardrail also has a good aesthetic appearance. Its surface presents a silver-white metallic luster, which is not only beautiful and generous, but also can improve the recognition of the corrugated guardrail and provide a guarantee for driving safety.
However, hot-dip galvanized corrugated guardrails also have some shortcomings. First of all, the cost of the hot-dip galvanizing process is high, resulting in a relatively high price of hot-dip galvanized corrugated guardrails. Secondly, the zinc-iron alloy layer formed by the hot-dip galvanizing process is relatively thick, which may increase the dead weight and installation difficulty of the corrugated guardrail.
In addition to hot-dip galvanizing, the commonly used anti-corrosion process of corrugated guardrail also includes electrostatic spraying. Electrostatic spraying on the basis of hot-dip galvanizing on the basis of electrostatic spraying powder, high temperature curing process, can further improve the anti-corrosion performance and aesthetics of the corrugated guardrail, according to different needs to choose the color of plastic powder, commonly used green, blue, white, yellow, gray, etc.
However, corrugated guardrails with different galvanized layer thicknesses and spray layer thicknesses are also different in terms of rust resistance, and the different thickness of the anti-corrosion layer will have an impact on the performance and price of corrugated guardrails.
In practical applications, the choice of corrugated guardrail should be decided according to the specific use environment and needs. For roads with high requirements such as highways, hot-dip galvanized corrugated guardrails or hot-dip galvanized sprayed corrugated guardrails with better rust resistance and higher aesthetics should be selected, while for roads with lower requirements such as rural roads, corrugated guardrails with thinner galvanized layer and thinner spray layer can be selected to reduce costs and meet basic needs.
In short, it is of great significance to choose a corrugated guardrail that is not easy to rust to ensure traffic safety. In practical application, the appropriate type of corrugated guardrail and corresponding anti-rust measures should be selected according to the specific use environment and needs to improve the service life and safety of the corrugated guardrail.
