Aluminum Bar Grating
Released time:10/9/2011 Click:

Aluminum Bar Grating is lightweight, corrosion resistant, non-sparking and has an unmatched strength-to-weight ratio. Manufactured from ASTM B221, 6063 or 6061 alloy, aluminum grating is available in four distinct products, type "SG" Swaged Rectangular Bar, type "SGI" Swaged "I" Bar, type "SGF" Swaged Flush-Top and type "ADT" Dovetail Pressure Locked. All four products are available with bearing bar spacing ranging from 19/16" (1-3/16") to 7/16" on center and with cross bars at either 4" or 2" on center. Rectangular bar products are manufactured with standard plain or optional serrated walking surfaces and "I" bar products are manufactured with a standard skid-resistant striated walking surface. Aluminum Bar Grating products are typically shipped “mill finish” with no additional treatment. For architectural applications or highly corrosive environments, supplemental anodizing, chemical cleaning or powder coat finishes are available. The following Aluminum Load Tables provide detailed specification information relating to all four aluminum products.

Swaged Rectangular Aluminum Grating
The most widely used aluminum grating, type "SG" rectangular bar provides clean, crisp lines and the cross bar is 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. Type "SG" gratings are available in close mesh ADA conforming spacings 11-SG-4 and 7-SG-4 which are commonly used in public areas. When specifying type 11-SG-4 for ADA applications, 3/16" thick bearing bars must be specified.

Swaged "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" aluminum grating, but weighs slightly less per square foot. Additionally, the striated top and bottom flanges of the "I" bar provide enhanced skid resistance without the cost of serration.

Swaged Flush-Top Aluminum Grating
Manufactured with a unique, extruded cross bar that is flush with the top surface of the bearing bars after swaging, 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.

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 “eggcrate” 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 architectural accent.
