Urban road signs buried in the ground are not constructed with attention to detail, resulting in premature corrosion and failure

The buried part of road signs corrodes and breaks down prematurely, with the main reasons usually including: 1. No effective anti-corrosion measures were taken for the buried part (such as galvanizing or applying anti-corrosion coatings). 2. The wrong materials were used, resulting in poor corrosion resistance. 3. Poor drainage measures for the buried foundation during installation, along with moisture underground, have led to increased corrosion. 4. The concrete was not properly protected or insulated, resulting in prolonged exposure to soil and moisture. Suggested solution: - Use hot-dip galvanized steel or other materials with stronger corrosion resistance. - The buried part is painted with anti-corrosion paint to ensure anti-corrosion and waterproofing. - Install a concrete foundation and provide drainage holes to prevent water from accumulating over time. - Conduct regular inspections and maintenance; repair or replace it promptly once corrosion is detected. .
