1. Record the specific dimensions of the rusted traffic facilities on the highway guardrail, and use a hammer to test the specific toughness on the fence. If a large area of paint loss or corrosion occurs, then the highway guardrail here has been erosion, the fragility of the internal metal elements can be imagined. The best way is to replace the old fence products in time. According to the specific road construction area, new guardrails are selected for actual installation.

2. The rusty guardrail should also be cleaned up in time and sorted back. As it is a common high-speed enclosure construction material, after professional recycling and degradation treatment, it still has a larger scope of application. Among them, the galvanized and electroplated anti-corrosion coating on the surface of the highway guardrail is mainly made of oxidized paint. During the production of highway guardrails, a layer of anti-corrosion equipment will be evenly

coated on it, which is more conducive to improving the anti-corrosion effect of highway guardrails.

3. If you want to solve the daily anti-corrosion of highway guardrails, regular maintenance is one of the indispensable links. Periodic maintenance is used to separate professionally the highway guardrail products with long distances. During the inspection of the expressway, it should pay more attention to whether the guardrails on both sides are damaged, welded, or severely corroded. If such a problem occurs, the highway management center should be notified in a timely manner, and it should be sent to professional maintenance personnel for on-site cleaning, Replacement or other maintenance work.
