Bridge curb and drainage ditch combined FD drain
This is a steel drainage channel designed to reduce the number of catch basins in bridges. With a double corrosion protection system of aluminum alloy plating and nylon coating, the product has a lifespan of approximately 50 years, which is about twice that of hot-dip galvanized products. Its maintenance-friendly design allows for openings from any direction. The integrated curb design enables a reduced cross-section structure, and by processing steel plates, it can reduce weight compared to concrete products. Additionally, it features a splash prevention function that ensures the lid does not detach and scatter even if a vehicle drives over the steel drainage channel, providing a safe structure.
