Aluminum bar grating is an ideal choice when a lightweight, corrosion resistant material is desired. Aluminum grating can be used for a variety of industrial applications, due its versatile and durable properties. Direct Metals® offers many options for aluminum bar grating, such as: rectangular bar, flush top, riveted, plank and I-bar aluminum bar grating products.
Aluminum Grating Advantages:
- Non-toxic
- Lightweight
- Resilient & durable
- Corrosion resistant
- High strength-to-weight ratio
- Can be fabricated and customized
- Easily recycled & versatile
One of the most common methods of manufacturing aluminum grating is through a swaging process. Swaged aluminum bar grating is defined by the NAAMM Metal Bar Grating Manual as “Grating in which the cross bars are mechanically locked to the bearing bars at their intersections by deforming or swaging the metal.” Direct Metals® uses the most modern swaging technology available to provide attached intersections. A mechanically attached joint will give your aluminum grating a long-lasting life under normal service conditions.
Another common type of aluminum grating is press lock grating. This type of aluminum grating has bars that are assembled together mechanically. The bars of this aluminum grating are locked into place by a hydraulic pressing process.
Direct Metals® offers many options for aluminum grating, such as swaged or press locked grating. Fabrication processes are available for these aluminum grating options. Some of these processing capabilities include slitting, spot welding, shearing, cutouts, cutting, banding, notching, toe plates, and weldments.
Aluminum Swaged Rectangular Bar Grating:
- Pressure locked by permanently attaching cross bars to bearing bars through a pressure applied swaging process
- Bearing bar sizes range from 1" x 1/8" through 2-1/2" x 3/16" in 1/4" increments
- Bearing bar spacing of 1-3/16", 15/16", 11/16" and 7/16" c.c. with cross bar spacing of 4" or 2"
- Press locked bar grating serrated surface can be provided when skid resistance is needed

Aluminum I-Bar Grating:
- Pressure locked aluminum grating which utilizes an “I” shaped bearing bar
- Bearing bar sizes range from 1" x 1/4" through 2-1/2" x 1/4" in 1/4" increments
- Bearing bar spacing of 1-3/16", 15/16", 11/16" and 7/16" c.c. with cross bar spacing of 4" or 2"
- Design consideration of the aluminum grating allows for the same load carrying capacity at less grating weight per square foot than rectangular bar, which results in cost savings

Aluminum Press Lock Bar Grating:
- Bar grating made up of interlocking perpendicular bars
- Bearing bar sizes range from 1" x 1/8" through 2-1/2" x 3/16" in 1/4" increments
- Bearing bar spacing of 1-3/16", 15/16", 11/16" and 7/16" c.c. with cross bar spacing of 4" or 2"
- Hydraulic pressure is used to bond the slotted bars together, locking the deep cross bar into the notched bearing bar
- Smooth, clean look due to a flush top rectangular cross bar
- Offers strong lateral stability
- Used in architectural design because of clean look and tight spacing
- 1/4" and 1/2" openings conform to the “Americans with Disabilities Act” (July, 1991)
- Slip resistant surfaces for floor grating available upon request
