Introduce
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 , 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.
Gratings Types
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 commonly used for public areas.
Type “SGI” Swage Locked I-Bar Steel 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.
Applications
Lightweight, corrosion-resistant, non-sparking alloys are ideal for
pedestrian platforms in chemical, petroleum, hydro and food
processing plants, in sewage, water and waste water treatment
facilities. Also available in close mesh and serrated.
