Riveted Bar Grating

 Compared to welded or swaged-locked grating, riveted has a
greater load carrying capacity for the same span and depth of
grating. Reticulated bars, riveted to the bearing bars increase
resistance to buckling cause by vehicular loading conditions.
Riveted carbon steel and aluminum gratings utilize rivets which
are individually cold-pressed using hydraulically and mechanically
operated riveting tools. Thus, the bearing bars and reticulated
bars are sealed together as a high-strength joint, freeing the
grating from the residual stresses that cause warp and joint
failures.
