Riveted grating is the oldest style and still a popular choice for industrial and commercial footwalk areas. It is still the choice of many engineers due to its reliability and durability along with its eye appeal. This grating is composed of straight bearing bars, and bent connecting bars, which are joined at their contact points by rivets. Since the connecting bars extend continuously between bearing bars along the grating spans, they not only serve to join the bearing bars together, but also contribute to the load carrying capability and lateral stability of the grating panels. This added dimension makes riveted grating an ideal choice where high strength and stiffness are required, or light vehicular rolling loads are encountered.
For areas requiring skid resistance due to the presence of moisture or oily substances, steel riveted grating is available with a serrated connecting bar. This bar is raised 3/16″ above the surface of the grating and provides a grip fast surface for the soles of shoes. Riveted grating is also available in stainless steel bar.
Bearing Bar sizes range from 1″ x 1/8″ through 5″ x 3/8″ in 1/4″ increments. Riveted grating is available with 1-1/8″ or 3/4″ between bearing bar faces, and with the connecting bars riveted at 7″ or 3-1/2″ centers.
