Deduct 1/16" for 1/8" bearing bars. Standard panel widths indicated in bold.*Based on 27.429 bars/ft. of grating width. Bearing bars 7/16" c.c. Add .6 lbs./sq. ft. for 7-TW-2. 1/8" bearing bars available upon inquiry. Note: Grating for spans to the left of the heavy line have a deection less than 1/4" for uniform loads of 100 lbs./sq. ft. This is the maximum deection to afford pedestrian comfort, and can be exceeded for other types of load at the discretion of the engineer. The actual “Ped (pedestrian) Span” under this condi-tion is shown above for each size of grating. When serrated grating is specied, the depth of grating required for a specic load will be 1/4" greater than that shown in these tables. 3/4" x 3/16" serrated grating is NOT available.IN STOCK!!ADA CompliantWt.*Lbs.Sq.
