Riveted Gratings are manufactured by cold-press riveting straight bearing bars to crimped rectangular flat bars. Our oldest products, riveted gratings offer superior resistance to impact, fatigue and repetitive loads.
Riveted gratings are available in carbon steel, 6000 series aluminum and 300 series stainless steels. These products are manufactured with bearing bars spaced either 1-1/8" or 3/4" apart and the standard rivet spacing is 7 inches on center. Optional close rivet spacing of 3-1/2" on center is also available.
The standard method of manufacturing serrated riveted grating is to serrate the crimped cross member. When assembled, these cross members are raised slightly above the top surface of the bearing bars to provide a superior unidirectional slip-resistant surface. If your application is particularly prone to unsafe walking conditions, consider specifying "100% Serrated" grating where both the bearing bars and cross members are provided with serrations.
The part numbers shown above are for carbon steel riveted gratings.
To specify aluminum or stainless steel products, replace the alpha character “R” with “AR” for aluminum products or “SR” for stainless steel products.
Type 18-AR-7 for riveted aluminum grating with bearing bars 1-1/8” apart and rivets at 7” on center.
Type 12-SR-7 for stainless steel riveted grating with bearing bars 3/4” apart and rivets at 7” on center.
