The project involved covering drainage channels along both sides of municipal roads, with clearly defined requirements for corrosion resistance, load-bearing capacity, and slip resistance. Based on the trench dimensions and vehicle traffic loads, the company custom-manufactured hot-dip galvanized trench covers. The products feature a smooth surface, efficient drainage performance, easy installation, and convenient maintenance and replacement. After being put into service, they effectively improved road drainage conditions while ensuring safe passage for pedestrians and vehicles.
