FLOW AREA FOR GRATES:

The net open area of each grate is listed, so that a general comparison of flow rates can be made. These open areas are figured for the entire grate. When determining actual flow areas, this should be reduced by the area of the seat. The net open area is calculated in square inches.

RESTRICTED GRATE OPENINGS:

When you design your project and you select a grate design, it is often necessary to consider slot size. We have identified the USF grates with relatively small slot lengths as “Restricted Grate Openings”. This term is applied when the slot lengths are 6 1/2 inches or less. The 6 1/2 inch dimension is an arbitrary length and does not imply the recommendation of a grate for any particular application.

ADA (AMERICANS WITH DISABILITIES ACT) APPLICATIONS:

When you design your project, you should be attentive of how the Americans with Disabilities Act (ADA) affects the placement of products. The application, as it relates to grating, states that grates in walking surfaces have slot openings 1/2 inch or less in one direction. Grates with elongated opening will be placed with long dimension perpendicular to the dominant direction of travel.

US Foundry offers many options to accommodate your ADA requirements including Trench and Inlet Grating, Catch Basins and Curb Inlets that are ADA compliant when installed properly. These products are found in our “Trench Grate” section, page here and throughout the “Catch Basin”, “Curb and Gutter” and “Cast Iron Grating” sections.  However, we do suggest reviewing ADA specifications before specifying a particular item. Contact us to see how we can meet your needs.
