Stormwater Management Grates
When selecting a grate for your system, consider the following: Load Class (resistance to pressure failure), Grate Length, Site Needs (e.g. ADA compliance, heel-resistance, etc.), Grate Material (affects load class, corrosion resistance, weight, general appearance), and Grate Design (affects intake area and aesthetics). For further detail, a Grate Visualizer is available here for this system.
