1. Record the specific size of the highway traffic sign post of the rusty road traffic facilities, and use the hammer to test the specific flexibility on the surface of the pole. If a large area of paint peeling or corrosion occurs, then the road traffic sign post here has been seriously corroded, and the vulnerability of the internal metal elements can be imagined. The more direct way is to replace the waste traffic sign post products in time. According to the specific road construction area, select new traffic sign posts for actual installation

2. Rusty traffic sign posts shall also be cleaned in time and taken back by category. As a common construction material for high speed traffic sign posts, it still has a wider scope of application after professional recycling and degradation treatment. The galvanized, galvanized and plastic sprayed anti-corrosion coating on the surface of road traffic sign posts is mainly made of oxide paint. During the production of road traffic sign posts, a layer of anti-corrosion equipment will be evenly coated on them, which is more conducive to improving the anti-corrosion effect of road traffic sign posts.

3. In order to solve the problem of daily anti-corrosion of road traffic sign posts, regular maintenance is one of the indispensable links. Regular maintenance in sections is adopted to professionally separate the road traffic sign posts with long distance. Road maintenance and construction personnel should pay more attention to whether the traffic sign posts on both sides are damaged, open welded or severely rusted during the regular detection of high-speed roads.
