' NOTE:Spans listed in the blue area produce a deflection of 1A"or less under a uniform load of 100 pounds per sq.ft. This deflection is recommended as the maximum to provide pedestrian comfort it can be exceeded at the discretion of the engineer. Spans listed in the blue area also define those gratings inconformity with NAAMM. NOTE:The carrying capacity of a piece of grating subjected to a concentrated load over only a portion of its width is determined by the stiffness of both the bearing bars and the cross bars,and therefore differs with the type of grating used.To determine the carrying capacity of gratings subject to such loadings,the IKG's engineering department should be consulted.
