After the fence material is rusted and corroded, how should it be solved? Presumably this is a topic of concern to everyone. Considering the intensive traffic flow of expressways, it is generally selected at noon or some road closure management opportunities to carry out road construction and maintenance section by section, which specifically involves the maintenance and protection of road guardrails on both sides, timely replacement of rust and corrosion, and road The size of the fence and so on. After a large area of rust occurs, specific treatment should be carried out according to the rusted area. The specific steps are as follows:

  

     First, record the specific dimensions of the rusty highway guardrail, and use a hammer to test the specific toughness on the fence. If a large area of ??paint peeling or corrosion occurs, it proves that the highway guardrail here has been seriously damaged. The corrosion, the fragility of the internal metal elements can be imagined. The best way is to replace the old fence guardrail products in time. According to the specific road construction area, a new guardrail is selected for actual installation.

 

     Secondly, rusty guardrails should also be cleaned up in time, and sorted and recovered. As it is a common high-speed enclosure construction material, it still has a larger scope of application after being professionally recycled and degraded. Among them, the galvanized and electroplated spray-plastic anti-corrosion layer on the surface of the highway guardrail is mainly made of oxide paint. In the process of producing 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.

 

     Finally, if you want to solve the daily anti-corrosion of highway guardrails, regular maintenance is one of the indispensable links. Regular maintenance is adopted to separate the long-distance highway guardrail products. During the inspection of the expressway, you should pay more attention to whether the guardrails on both sides are damaged, welded or severely corroded. If such a problem occurs, you should promptly notify the expressway management center to send professional maintenance personnel to clean the site. Replacement or other maintenance work.
