Drainage grates are metal or plastic covers placed over drainage systems to allow water to flow into the drainage while preventing larger debris from entering. They are commonly found in streets, parking lots, and sidewalks, helping to manage stormwater and reduce flooding. These grates come in various shapes and sizes, designed to fit specific drainage openings. Their design often includes slits or holes that facilitate water flow while ensuring safety for pedestrians and vehicles. Regular maintenance is essential to keep them clear of blockages, ensuring effective drainage and preventing water accumulation.
