Corrosion
resistant, non-sparking, rustproof aluminum grating has
many applications due to its light weight and high strength.
It is
ideally suited for use in corrosive environments and finds wide
applications as walkways and platforms in sewage treatment
plants, refineries, chemical processing plants, pumping and
compressor stations, and aboard ships and barges. Because it
does
not rust, it is commonly used in breweries, bottling plants,
and
food preparation and storage facilities. In munition plants,
other
volatile industries and areas, its non-sparking properties make
it a
must for safety.
The
I-Bar SGI Series offers
a popular and reasonably priced alternative to rectangular bar
grating. Extruded I-Bar sections have the same load carrying
capacity with less weight per square foot than rectangular bars.
The striated
top and bottom flanges provide a "built-in" skid resistance
feature without the added cost of serration.

*Note:
Based on 10.105 bars/ft. of grating width. Bearing bars 1-3/16"
c.c. Note: Grating for spans to the left of the heavy line
have a deflection less than 1/4" for uniform loads of 100
lbs./sq. ft. This is the maximum deflection to afford pedestrian
comfort and can be exceeded for other types of load
at the discretion of the engineer. The actual Ped (pedestrian)
Span under this condition is shown above for each size
of grating. When serrated grating is specified, the depth of
grating required for a specific load will be 1/4" greater
than that shown in these tables.
