Selecting Bar Grate that is ADA Compliant

September 15, 2010

The Department of Justice revised the Americans with Disabilities Act (ADA) on September 15, 2010 to ensure government buildings, public accommodations, and commercial facilities are readily accessible and usable by individuals with disabilities.

Are you and your facility following the new guidelines set by the ADA?  The following requirements for bar grate, among others, may apply to you:

  • If bar grates are located in walking surfaces, than they shall have spaces no greater than 1/2 (13 mm) wide in one direction
  • If gratings have elongated openings, then they shall be placed so that the long dimension is perpendicular to the dominant direction of travel
  • Walking surfaces should be slip resistant, a coefficient of friction of 0.6 is recommended for routes and 0.8 for ramps

SlipNOT® offers slip resistant bar grate that has a coefficient of friction that is greater than or equal to 0.85, exceeding the requirements of the ADA.   Among many styles of bar grate, SlipNOT® offers the following ADA compliant options:

  • 7-2
  • 7-4
  • 11-2
  • 11-4

These bar grate styles represent the amount of space between the bearing bars and cross bars.  The bearing bars (the longer dimension that is measured by span) have to run perpendicular to the route of traffic.  The cross bars are the bars that are measured by width.  For example, the 7-2 bar grating means there is 7/16” between bearing bars and 2” between cross bars.

SlipNOT® bar grate is available in steel, galvanized steel, aluminum and stainless steel.  SlipNOT® products are low maintenance and have a long life cycle, making them ideal for applications such as sidewalk grates, walkways and other public areas where drainage and slip resistance are critical.
