Why Are Highway Guardrails So Colorful?
1. Firstly, brightly colored highway guardrails can alleviate drivers' visual fatigue in long-duration driving environments. Then, some colored guardrails act as reflectors at night, providing drivers with excellent lane guidance and allowing them to navigate in the dark more safely. The use of different colored guardrails will attract more attention, thereby enhancing driver alertness and maintaining safe passage.
2. The techniques for creating different colors on highway guardrails include electrostatic powder coating, immersion coating, and epoxy zinc-based coating. The most commonly used process is the electrostatic powder coating on the surface of highway guardrails. Electrostatic powder-coated highway guardrails refer to the静电powder spraying finishing technique. Under the influence of an electric field, the paint is sprayed onto the surface of the workpiece, where the powder evenly adheres to form a powdery coating, and there is no dripping during the electrostatic powder spraying process.
How to Maintain Highway Guardrails?
1. Do not use cold water to wipe the highway wave-shaped guardrails during winter, as this can cause the water to freeze and adhere to the guardrails, leading to corrosion.
2. In case of snowfall, it is essential to promptly clear accumulated snow from information堆积 on guardrails after the snowfall.
3. Upon discovering damage to the surface protective layer, promptly apply paint to ensure the integrity of the coating.
We encountered corroded areas that required sandpaper or steel wool for rust prevention, followed by the application of protective coatings.
