Why aluminum?
Aluminum bar grating provides a lightweight alternative to it's steel counterpart. With its different corrosion characteristics, aluminum has a wide range of uses. It is not recommended to use aluminum grating for any rolling wheel loads.
Aluminum bar grating comes in many options such as: rectangular bar, I-bar, flush top, & riveted. Bearing bar sizes range from 1" x 1/8" through 2-1/2" x 3/16" in 1/4" depth increments. Bearing bar spacing of 7/16" through 1-3/16" with cross bars available at 2" or 4" centers. Where skid resistance is desired, a serrated surface can be provided on rectangular bar grating.

If you are looking for heavy duty/traffic rated material, please check out our Steel products.
Swaged Grating
Swage-locked aluminum grating is manufactured with either an "I" or rectangular bearing bar. These
bearing bars are permanently locked to the cross rods with a swaging process which reshapes the
cross rods. Because of flange width, I-bars reduce the open spaces of the grating, yet I-bar
swage-locked is lighter weight and maintains load ratings. Swage-locked I-bar grating is the most
widely used and provides the strength equal to a rectangular bar of the same depth, but at far less
weight. Rectangular swage-locked is available with the cross rods flush with the top of the bearing bars,
or with the cross rods near the middle of the bearing bar. These options are available if a specific look is desired.
Dove Tail Grating
Dove tail grating is constructed with two close-tolerance slotted bars bonded together (positioned
every 2" or 4") using tremendous hydraulic pressure on rectangular bars. Permanent locking is
achieved by forcing the deep cross bar into the bearing bar. Both the cross bars and bearing
bars provide walking surfaces in the press-locked design. Rectangular bar grating in either
swage-locked or press-locked styles is your best choice when lateral stiffness is required. The
rectangular bars are also offered with a serrated surface for additional traction and safety.
Rectangular v I-Bar Grating
Both rectangular and I-bar aluminum grating offer comparable strength.
Rectangular bar is offered in various crossbar configurations and can be either plain or serrated.
I-bar is only available in a swaged connection and is always striated. This bar is lighter weight than
rectangular bar and is a great option for any project that has weight limit restrictions.

Stair Tread
Aluminum stair treads, due to their light weight, high strength, corrosion resistance, rust proof and non sparkling properties, are ideally suited for corrosive environments, food preparation and storage areas, and volatile areas. Swage-locked I-bar treads offer you high strength at less weight.
Rectangular bar, press-locked or swage-locked, provide higher strength and stiffness-to weight ratio and are available with a serrated surface when additional safety is required. All stair treads are custom fabricated to meet the size, width and length specifications of a particular job. In addition, standard end plates or custom fabricated end plates can be used to meet any bolt hole size or location requirements.
Different types of nosing are available to add a definitive visible edge and slip resistance for extra safety.
Aluminum stair treads are available in light duty and close mesh options.
Below is a list of available bar sizes, standard widths, and their maximum spans for pedestrian loads.
Grooved nosing is standard, but other options are available upon request.
End plates are standard for stringer connections. Banded or open ends can be done upon request.
See the End Plate Details and Load Chart below for information regarding sizing, spacing, and maximum lengths.
