ALUMINIUM PLANK GRATING
Aluminum Plank Grating is a structurally sound and cosmetically attractive alternative to bar grating. Extruded in 6″ and 2-1/2″ wide sections, plank grating is relatively maintenance free and has no parts to work loose or splinter.
The solid, striated walking surface can be provided “unpunched” which restricts the passage of debris and is preferred for odor containment applications. When the passage of air, light, heat or moisture is desired, aluminum plank can be punched with a variety of hole patterns including rectangular, square, round or diagonal. Enhanced slip-resistance is available by specifying “upset” punched square or rectangular patterns.

RIVETED GRATING
Riveted Gratings
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.
Materials
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.
Serrated Surface
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.
Examples:
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.
ARCHITECTURAL GRATING
Interstate Gratings’ complete line of bar gratings and Architectural Products offer a distinct, contemporary design for architectural accents. Increased spacing between the bearing bars provides security and structural integrity without restricting sight lines and ventilation. The perfect merger of form and function, these products can be fully fabricated to complement design creativity.
