Aluminum Bar Grating
Product Overview
Aluminum bar grating is lightweight, corrosion resistant, and fully recyclable. With an unmatched strength-to-weight ratio, these products are ideal for both industrial and architectural applications.
Manufactured from ASTM B221, 6063 or 6061 alloy, aluminum grating is available in four distinct product types. Bearing bar spacings range from 19/16” (1-3/16”) to 7/16” on center and cross bars at 4” or 2” on center.
Aluminum products are available in standard mill finish. Optional anodizing, chemical cleaning, or powder coated finishes are available for highly corrosive or architectural applications.
Types of Aluminum Bar Grating
Type “SG” Swage Locked Aluminum Grating
The most widely used aluminum grating, type SG rectangular bar, provides crisp lines. Bearing bars are available with standard plain or optional serrated or OnGrip surfaces. The cross bars are fully locked within the bearing bar, slightly below the top surface.
Type 19-SG-4 aluminum grating is the industry recognized standard for industrial applications. With nearly 80% open area, 19-SG-4 is virtually self-cleaning, allowing for easy passage of dirt, debris, snow, and liquids.
Type SG gratings are available in close mesh ADA conforming spacings 11-SG-4 and 7-SG-4, which are commonly used for public areas.
Type “SGI” Swage Locked I-Bar Aluminum Grating
Manufactured with highly efficient “I” shaped extruded bearing bars, type SGI aluminum grating carries the same load as 3/16” thick rectangular bar type SG grating.
The I-bar reduces total weight per square foot and the striated flanges provide increased slip resistance without the added cost of serration.
Type “SGF” Swaged Flush-Top Aluminum Grating
Manufactured with a unique, extruded cross bar that is flush with the top surface of the bearing bars, type SGF aluminum grating provides an enhanced walking surface for areas subject to continuous pedestrian traffic.
Available in rectangular bar with plain or serrated surfaces, type SGF aluminum grating is also available in ADA conforming spacings for applications located in the public way.
Type “ADT” Aluminum Dovetail Pressure Locked Grating
Type ADT aluminum gratings have deep rectangular cross bars and are manufactured by inserting pre-punched bearing bars and cross bars into an “egg-crate” configuration and deforming the cross bars under intense hydraulic pressure.
The deep cross bars on type ADT gratings make them popular for architectural applications such as sun shades and infill panels with the deeper cross bar serving as a distinct visual accent.
