On July 26, 1991 the Architectural and Transportation Barriers Compliance Board (Access Board) published the Americans with Disabilities Act Accessibility Guidelines (ADAAG). The ADA establishes accessibility requirements for new construction and alterations of State and local government facilities, and places of public accommodation and commercial facilities. As updated in the November 16, 1999 ADAAG Notice of Proposed Rule making, section 302.3 states that "openings in floor or ground surfaces shall allow passage of a sphere not more than 1/2 inch (13 mm) diameter. Elongated openings shall be placed so that the long dimension is perpendicular to the dominant direction of travel." Ohio Gratings manufactures Aluminum, Light Duty Carbon and Stainless Steel, and Heavy Duty Carbon Steel grating products which conform with the spacing requirements of the ADA Accessibility Guidelines for Buildings and Facilities. The specification and use of this family of GRATER AccESS® products will ensure that your project is both pedestrian friendly and vehicle safe. Since these Accessibility Guidelines are subject to change, please contact the factory for up-to-date information regarding the use of grating in ADA applications.
