 Aluminum
Bar Grating is a good choice when a lightweight, corrosion
resistant material is desired. Choose from many options such
as: flush top, riveted, rectangular
bar, plank, & I-bar aluminum
bar grating products.
The most common method of manufacturing aluminum bar grating
is through a process known as pressure locking. Pressure locked
grating as defined by the NAAMM Metal Bar Grating Manual is “Grating
in which the cross bars are mechanically locked to the bearing
bars at their intersections by deforming or swaging the metal.” Direct
Metals has taken advantage of the most modern technology available
to provide a permanently attached pressure locked joint which
will give long lasting life under normal service conditions.

Aluminum Rectangular Bar:
 A
type of pressure locked aluminum bar grating made 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” are available.
Where skid resistance is desired, a serrated surface can
be provided. |
|
Aluminum Flush Top:
 A
type of pressure locked grating in which the cross bars are
in the same plane relative to the top surface of the aluminum
bar grating. Bearing bar sizes range from 1” x 1⁄8” through
21⁄2” x 3⁄16” in 1⁄4” increments.
Bearing bar spacing of 13⁄16”, 15⁄16”,11⁄16” and
7⁄16” c.c. and cross bar spacing of 4” or
2” are available. Where skid resistance is desired,
a serrated surface can be provided.

Aluminum Plank:
 A
type of extruded grating which is available in 6" wide
sections, and either plain sided or interlocking. Aluminum
plank bar grating can be provided in sections up to 26'0" in
length, or fabricated per plans and specs. Plank grating
is available unpunched as an economical and structurally
superior substitute for aluminum checkerplate, or with
a variety of punch/patterns.

I-Bar:
 A
type of pressure locked grating which utilizes an "I" shaped bearing
bar ranging in size 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.
and cross bar spacings of 4" or 2" are available.
The I-Bar design takes advantage of the aluminum extrusion process by placing
the metal where it is most effective - at the outermost edge - while reducing
the thickness for the neutral axis web. This design consideration allows the
aluminum I-bar grating the same load carrying capacity at less weight per square
foot than rectangular bar therefore resulting in a cost savings. |

Aluminum Riveted:
 A
type of aluminum grating which combines straight bearing
bars and bent connecting bars riveted together at their
contact points. Riveted grating, although being the oldest
style of industrial footwalk, is still the choice of many
engineers due to its reliability and durability. All popular
sizes and spacings of riveted grating are sold by Direct
Metals with an emphasis on quality and service. |
