Grates with elongated opening will be placed with long dimension perpendicular to the dominant direction of travel. Storm Drain effectively collects and distributes large volumes of surface water throughout its system. The application, as it relates to grating, states that grates in walking surfaces have slot openings 1/2 inch or less in one direction. Our stormwater drainage grate range includes, cast in and drop in hinged grate and frames, sump grates, kerb entry grates, V Grates, surcharge grates, trench grating and more. RELN Storm Drain is the complete surface drainage solution, with a deep 100mm profile. When you design your project, you should be attentive of how the Americans with Disabilities Act (ADA) affects the placement of products. The 6 1/2 inch dimension is an arbitrary length and does not imply the recommendation of a grate for any particular application.ĪDA (AMERICANS WITH DISABILITIES ACT) APPLICATIONS: This term is applied when the slot lengths are 6 1/2 inches or less. We have identified the USF grates with relatively small slot lengths as “Restricted Grate Openings”. When you design your project and you select a grate design, it is often necessary to consider slot size. The net open area is calculated in square inches. When determining actual flow areas, this should be reduced by the area of the seat. These open areas are figured for the entire grate.

The net open area of each grate is listed, so that a general comparison of flow rates can be made.
