Aluminum Plank Grating Series
PRODUCT PRESENTATION
As an alternative to bar grating,
Aluminum Plank is structurally sound and cosmetically attractive. The surface
can be provided unpunched, or with a variety of rectangular and square
punch patterns for the passage of air, light, heat or moisture. The interconnecting
webs offer a flush top walking surface for maximum foot contact and comfort.
Plank is available in 6" wide plain sided sections 3/4" through 2-1/2"
high, or 1" high interlocking sections. Individual sections can be banded
together to form standard panel widths for ease of handling and installation.
For those areas requiring maximum skid resistance, Ohio Gratings offers
two styles of upset pattern for rectangular punched plank. Upset Pattern
(OGI) features connecting webs with two raised transverse ribs for stiffness
and skid resistance. Upset Pattern (WACO) combines the rectangular or square
opening with an upturned edge condition.
OVERALL PRODUCT
Standard Grating Details
Typical details for grating frames
and grating anchorage methods are shown in the CAD details attached to
this profile, accessible through the "CAD" button on the interface.
General recommendations for installation
include:
1. All gratings should be anchored
to their supports by positive means. See the "Grating Anchorage Details"
section below.
2. A minimum of 1" bearing shall
be provided.
Extruded Aluminum Grating Frames
Available for use with all types
of aluminum grating is an extruded frame for embedded concrete applications.
This frame features a continuous ledge to accommodate plank fasteners,
grating clamps, or self-tapping screws for saddle clips or anchor blocks.
This ledge allows the grating to be fastened to the frame without the necessity
of pre-drilling into the concrete. The extruded design also incorporates
a labor saving continuous anchor. The continuous anchor can be used alone,
or in conjunction with supplementary anchor straps.
Angle frame is available fabricated
per drawings with mitred corners, or in long lengths with prefabricated
corners for installation in the field. Frames can be provided in the mill
finished condition or with a coat of bituminous paint on surfaces which
will come into contact with concrete.
Grating Anchorage Details
All gratings should be firmly anchored
to their supports by positive means. The method of anchorage depends on
the circumstances of the application in question. Refer to the CAD details
attached to this profile, accessible through the "CAD" button on the interface
for isometric details of the following anchorage devices:
Plank Clip
Plank clips are special aluminum
friction fasteners used in conjunction with plank grating and embedded
grating frames. When plank is banded, clips are installed by the manufacturer.
ASSEMBLY, INSTALLATION
Fabrication Guidelines
Frame sections can be purchased
in stock lengths for customer fabrication, or can be fabricated by Ohio
Gratings for immediate installation in the field. The following guidelines
apply to fabricated frames:
1. All corners are mitred at 45
degrees and welded on the back side. Welds are not ground.
2. Nominal small frames (i.e., 1'-0"
x 1'-0" through 5'-0" x 10'-0") are made in one piece.
3. Extended trench frames are provided
with prefabricated end sections and long lengths shipped loose for field
butt joining.
4. Stock lengths are 20'-0". Longer
lengths are available by request.
Architectural Applications and
Tolerances
"Aluminum grating is an industrial
footwalk product, intended for use in catwalks, platforms, and stairways,
and designed to be installed in a fastened condition. This grating is also
subject to manufacturing and fabrication tolerances as dictated by the
NAAMM Metal Bar Manual. While these tolerances and the various finishes
available are suitable for most industrial applications, they may not be
appropriate for some commercial or architectural uses. Please contact the
factory for further specification assistance."
COATINGS, SURFACING
SLIP-NOT Safety Surface Available
ALUMINUM Riveted Series grating
is available with SLIP-NOT Grip Grate safety surface for maximum traction.
The SLIP-NOT process provides for the plasma stream deposition of aluminum
on aluminum resulting in a random hatch matrix which continuously presents
new abrasive faces as the surface slowly wears.
SLIP-NOT exceeds OSHA standards for
"Slip Resistance" in dry, wet, and oily conditions.
SLIP-NOT is generally applied after
grating fabrication, however, grating treated with
SLIP-NOT can be cut, punched, drilled,
or welded in the shop or in the field.
For complete technical information on SLIP-NOT,
refer to the Sweets catalog for W.S. Molnar Co., 05542/SLI. SLIP-NOT Grip Grate
is a registered trademark of W.S. Molnar Co.
