Stainless Steel Bar Grating
Stainless Steel Grating
When caustic atmospheres are encountered or when corrosion resistance and/
or minimum carbide precipitation are
essential considerations, AMICO stainless
steel grating is the answer. The longerlasting capabilities of stainless steel
under these special conditions make it an
economical selection over the long term.
It is ideal for use in food processing
areas, breweries, bottling plants, dairies
and meat packing plants. Stainless steel
can also be used in power plants, sewage
treatment plants, pumping stations and
hydrocarbon processing facilities where
various caustic environments are normal.
It also has application in shipboard and
building industries where saline solutions
or atmospheres are present.
Stainless Steel Bar Grating is available
in welded, riveted, swage-locked and
press-locked types, which are designated as S, RS, SS and SP, respectively.
Heavy-duty welded bar gratings and RivDexteel,® which are designated as HS,
RSL and RSH, respectively, can also be
manufactured from stainless steel.
The alloys listed here are available as
standard products. Each conforms with
ASTM A-167. In addition, special alloys
are available upon request.
Finish
Unless otherwise specified, stainless
steel grating shall have a mill finish.
Stainless steel will show some discoloration around the joints due to welding.
Finishes available to remove discoloration include sandblasting and electropolishing, the latter being used where
bright finish is desired. Shot blasting or
wire brushing should be avoided since
these operations can cause iron contamination which, if not removed, will cause
rusting and discoloration of the surface.
Such contamination can be removed by
passivation. Electro-polishing leaves a
passive surface. The swage-locked and
press-locked processes will not show
discoloration.

General Descriptions
Type 304 alloys resist most oxidizing acids and can withstand all ordinary rusting. They are
immune to foodstuffs, sterilizing solutions, most of the organic chemicals and dyestuffs, and
a wide variety of inorganic chemicals. This grade should be considered for use unless some
special mechanical, physical or fabricating characteristic is required.
Type 304L is the low carbon modification of Type 304. This minimizes the problem of
carbide precipitation during welding.
Type 316 alloys have superior corrosion resistance especially to sulfurous acid compounds
and many chemicals used by the chemical process industries. It is more resistant to pitting
corrosion than typical 18-8 alloys (Chromium-Nickel), such as Type 304.
Type 316L is the low carbon modification of Type 316. This minimizes the problem of
carbide precipitation during welding.
The modulus of elasticity for stainless alloys is 28,000,000 psi.
Stainless Steel Bar Grating
Available in same spacing patterns and bearing bar sizes as
carbon steel grating (see pages 3-9).

Heavy-Duty Steel Bar Grating
Heavy-Duty Welded Grating has the
strength for heavy-duty load areas such as
airfields, industrial plants, truck and bus
terminals, parking lots and railroad yards.
Common uses are flooring, driveways,
subway and tunnel ventilation grilles, curb
inlet grates, ramps, docks, etc.
It is a sturdy grating to carry loads and
maintain the same level over many years
of use. Whenever rolling wheel loads are
to be used over the grating, we recommend that the grating be load banded to
add lateral strength. Serrations are available on bars up to 3/8” thick to provide
additional traction for rolling loads.
Standard heavy-duty bar grating is
resistance-welded for durability, strength
and safety using an automated electric/
hydraulic welding process. High temperatures, combined with high pressure, fuse
the bearing bars and cross bars together
to form a permanent joint.

Deflection: Spans and loads to the right of the bold line exceed 1/4” deflection for
uniform load of 100 psf which provides maximum pedestrian comfort. These can be
exceeded for other types of loads with engineer’s approval. For deflections of uniform, concentrated and vehicular loads, consult AMICO’s e
ngineering departments.

Riveted Grating
Riveted Bar Grating is the first choice by
many engineers for many applications. Compared to welded or swaged-locked grating,
riveted has a greater load carrying capacity for the same span and depth of grating.
Reticulated bars, which are riveted to the
bearing bars, increase resistance to buckling
caused by vehicular loading conditions.
AMICO riveted carbon steel and aluminum
gratings utilize rivets which are individu-
ally cold-pressed using hydraulically and
mechanically operated riveting tools. Thus,
the bearing bars and reticulated bars are
sealed together as a high-strength joint.

grating width, lbs.
Material: ASTM B-221
Serrated Bars: Normally we serrate the reticuline bar and raise it slightly above the top
surface of the bearing bars. We can also serrate the bearing bars. When bearing bars are
serrated, the depth of grating required for a
specified load is 1/4” deeper than that shown
in the table.
General: Loads and deflections are theoretical
400256178131100 79 64 53
and based on static loading.

Riv-Dexteel® Bridge Deck Grating
Compared to other surfaces, Riv-Dexteel® is relatively lightweight and frequently permits bridge widening without an appreciable increase in bridge
weight. It often allows resurfacing to handle heavier loads without expensive substructure work.
It is ideal where flooding, snow build up or icing is a potential problem
since its openness permits passage of snow and water that a solid surface
does not allow.
In addition to its common applications as bridge decking and curb inlet
grates, it has wide applications in industrial flooring areas, plant loading
areas, driveways across culverts and other heavy traffic areas.
RL Plain Surface
RL Serrated
Riv-Dexteel® is available in an RL and RH design. RL Riv-Dexteel® has bearing bars spaced 2-1/2” to 2-11/16”, depending on the bar thickness. Reticulated bars are 1-1/2”x3/16” for all RH types and RL types with bearing bar
heights 3” or below, and 2”x3/16” for RL types with bearing bar heights
3-1/2” or above. RL is available in both plain and serrated surfaces.
RH Riv-Dexteel® has bearing bars spaced 5-1/8” to 5-1/4” with 3/16” x
1-1/2” reticulated bars and 1/4” x 1-1/2” intermediate bars. In addition, RH
has 1/2” by 3/4” tie bars for additional lateral stability. RH is also available
with both plain and serrated surfaces.
Upon request, other bearing bar depths and thicknesses are available.

Basis for Design
The design of the Riv-Dexteel Bridge Deck Grating is in accordance with
AASHTO Standard Specifications for Highway Bridges (17th edition) and
NAAMM Metal Bar Grating Engineering Design Manual (MBG 534-12). The
allowable fiber stress is 20,000psi; the allowable deflection is the lesser of
L/400 or 1/8in. AMICO recommends bearing bars to be installed parallel to
traffic. If the owner’s engineer specifies placement perpendicular to traffic,
measures should be taken to minimize the effect of out-of-place bending of
bars due to vehicle acceleration and breaking. The engineer must specify
hold down anchors at ends and supports as necessary.
serrated bars
Normally we serrate the reticulate bar and raise it slightly above the top surface of the bearing bars. We can also serrate the bearing bars. When bearing
bars are serrated, the depth of grating required for a specified load is 1/4”
deeper than that shown in the table.

Note: D
imension includes 1/4” (1/8” each side) for rivet heads. Rivet heads vary with bearing bar thickness.

use our online calculator at
www.amico-grating.com/ calculator
or consult AMICO.
The clear spans shown in this table are based upon simply supported single-span calculations using “SB.” Multi-span calculations using “ST” are acceptable when approved by the owner’s engineer. Consult AMICO for details.

Aluminum Bar Grating
Aluminum grating has many applications due to its corrosion resistance,
light weight, and high strength construction. These applications include, but not
limited to:
•walkways and platforms in sewage
treatment plants
•refineries and chemical processing
plants
•pumping and compressor stations
•aboard ships and barges
•breweries, bottling plants, and facilities
for food preparation and storage
•munition plants and other volatile
industries and areas, where its non-
swage-locked I-Bar Aluminum Grating
32
sparking properties make it a must
for safety.
Aluminum grating is available in standard or anodized finishes.
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 and
cost. The I-bars are permanently locked
to the cross rods (positioned every 2” or
4”) by a swaging process.
Swage-Locked Rectangular Bar Grating uses the swaging process to permanently lock the cross rods (positioned
every 2” or 4”) to the rectangular bars.
Swage-locked Rectangular Bar Aluminum Grating
Press-Locked Rectangular Bar Grating
is constructed with the two close-tolerance slotted bars bonded together (positioned every 2” or 4”) using tremendous
hydraulic pressure. Permanent locking is
achieved by forcing the deep cross bar
into the bearing bar. Both the cross bars
and the bearing bars provide walking
surfaces in the press-locked design.
Rectangular bar grating in either the
swage-locked or press-locked styles is
your best choice when lateral stiffness
is required. The rectangular bar is also
available in a serrated surface for additional safety.

Duo-Grip™ Planking, a one-piece extruded 26’ long plank (standard), is available only from AMICO and has an exceptional strength
and stiffness-to-weight ratio due to its integral I-beam ribs. It is available in either unpunched, square punched or rectangular
punched styles to suit lighting and ventilation considerations. The 6” wide panels are welded together to form the desired panel
width and an extruded aluminum end bar is welded into place. The design provides a surer walking surface for additional safety.
45
Stair Treads
All of AMICO’s bar grating stair treads are designed and manufactured to
comply with load requirements of ANSI/NAAMM MBG 531. AMICO stair
treads are safe, self-cleaning, slip-resistant and economical. Steel and aluminum stair treads are available in a variety of styles: welded, riveted, presslocked, swage-locked and Duo-Grip™ extruded aluminum.
Swage-locked I-bar stair treads offer you high strength at less weight and
lower cost. Rectangular bar, press-locked or swage-locked, stair treads provide a high strength and stiffness-to-weight ratio and are available with a serrated surface when additional safety is required. Our Duo-Grip™ plank stair
treads give you an exceptional strength and stiffness-to-weight ratio.
Welded steel stair treads are the most widely used for their strength and ease
of installation and are universally used in most industrial and commercial
applications. Riveted steel stair treads have a greater load carrying capacity
for the same span and depth of bearing bar and greater walking comfort.
Both can be ordered with a serrated surface for additional safety.
All stair treads are custom fabricated to meet the size, width and length
specifications of a particular job. In addition, end plates can be custom fabricated to meet special bolt hole size or location requirements.
Aluminum stair treads, due to their light weight, high strength, corrosion
resistance, rust proof and non-sparking properties, are ideally suited for corrosive environments, food preparation and storage areas, and volatile areas.
Stair Tread Tolerances and details
Both steel and aluminum nosings are available to add strength at the point of
greatest impact and provide a definitive visible edge for extra safety. Choose
our checkered plate nosing for normal use. For additional safety, choose our
cast aluminum abrasive nosings or our corrugated aluminum nosings, or
dimple nosing available in carbon, stainless or aluminum.

The saddle clip bridges two bearing bars and is attached
with 1/4” self-tapping bolt, 1/4” self threader, 1/4” weld
stud or 1/4” bolt and nut when hole is drilled through supporting flange. Available for 15/16”, 1-3/16” and 1-3/8”
bearing bar spacings (15, 19 and 22 space) in carbon and
stainless steel. Fasteners should be specified separate
from clips. (Bolts not included)
Type H-1 Anchor Clip
A flat head J-bolt secures a preformed plate to
the underside of steel bearing bars and structural
supporting flange. No drilling needed. Access to
the underside of grating is required for installation.
Available in carbon steel. J-bolt is 1/4” x 2-1/2”
for grating up to 2-1/4” deep and 1/4” x 3-1/2” for
2-1/2” to 3-1/2” deep grating.
Attachment Locations
Attachments should be placed at intermediate supports in the middle
of the panels and at the four bearing bar ends, 6” from each side
of panel. Welds should be 3/16” fillet welds, 3/4” long. Heavy-Duty
grating may require additional welding to meet application needs.
Welds
Recommended for all permanently installed grating
panels. Welds should be 3/16” fillet welds, 3/4” long
located approximately 6” from each side of panel (4
locations) and one weld in middle of panel at each
intermediate support.
Weld Lugs
Weld lugs may be used for installations
where grating is subject to removal.
Weld lugs are shop fabricated and must
be specified at time of grating order.
Fasteners are 1/4” minimum and supplied by others. Location is the same as
“Attachment Locations” diagram.

Diamond-Grip®
PRODUCT DESCRIPTION
Diamond-Grip® is a one-piece metal plank grating manufactured by a cold
forming process in the shape of a channel. The web of the channel is the
walking surface and has rough serrated edges around diamond shaped
openings.
FEATURES & BENEFITS
• Serrated edges around diamond shaped openings provide slip
resistance under slippery conditions such as snow, ice, grease, oil, etc.
• One-piece metal construction.
• Lightweight design provides high strength to weight ratio.
• Long life span requiring little maintenance.
• Simple and economical installation as planks are self-framing.
• Adaptable to cost effective custom fabrication.
• Can be easily formed in standard channel or custom shapes.

Safety Grating
Diamond-Grip® Walkway
PRODUCT DESCRIPTION
Diamond-Grip® walkway is a one-piece metal plank grating manufactured
by a cold forming process in the shape of an inverted channel. The web of
the channel is the walking surface and has rough serrated edges around
diamond shaped openings. Diamond openings are complete with radiused
corners at the saddle and side channel location. The extended flanges support the load and provide a built in kickplate (toeboard).
FEATURES & BENEFITS
• Serrated edges around diamond shaped openings provide slip resistance
under slippery conditions such as snow, ice, grease, oil, etc.
• Radiused corners reduce the possibility of stress cracks across saddles
or at the side of channels under various loading conditions.
• Self-cleaning due to resilience of walking surface.
• One-piece metal construction complete with a full height toeboard on
each side of the walking surface.
• Simple and economical installation as walkways are self-framing.
Grating shall be “Diamond-Grip® walkway,” manufactured from (see
‘Selections’ below) and complete with an (4-1⁄2”, 5”) integral toeboard,
by AMICO.
• Selections
• ASTM-A-653, G-90 (Z-275) pre-galvanized 14 or 12 gauge steel.
• ASTM-A-1011, HRP&O 14 or 12 gauge steel.

of 1.67.
• Strut deflection may become a limiting factor resulting in
lower load values as indicated in table.
TechnicaL Details
Note:
• Tolerances on all dimensions are ±1/8”
• Standard lengths are 121 1⁄2” & 144”.
• Tolerance on manufactured and cut lengths is ±1/8”.
• When cutting Diamond-Grip®, AMICO® recommends cutting to full or half diamond increments.
•Camber is an expected condition with sheet metal products. While ASTM allowance is generous, AMICO attempts to lessen the
effects. Normal clearances should offset this phenomenon, however where tolerances warrant, contact AMICO for clarification.

Safety Grating
safety-Grip®
PRODUCT DESCRIPTION
Safety-Grip® is a one-piece metal plank grating manufactured by a cold forming
process in the shape of a channel. The web of the channel is the walking surface and has large debossed holes, surrounded by smaller embossed traction
buttons.
features & benefits
• Embossed traction buttons provide superior slip resistance in all directions
and in all weather conditions.
• Large debossed holes provide maximum drainage of debris and allow up to
50% free air opening depending on channel width.
Grating shall be “Safety-Grip® channel,” manufactured from (see ‘Selections’
below) and complete with a (1-1/2”, 2”, 3”) side channel depth, by AMICO.
• Selections
• ASTM-A-653, G-90 (Z-275) Pre-galvanized 13 or 11 gauge steel.
• 5052H32 Aluminum .125” thick (up to 18” width).
• Type 316L 2B Stainless Steel 14 gauge (up to 12” width).
• Type 304L 2B Stainless Steel 16 gauge (up to 12” width).

Safety Grating
Safety-Grip® Walkway
PRODUCT DESCRIPTION
Safety-Grip® walkway is a one-piece metal plank grating manufactured by
a cold forming process in the shape of an inverted channel. The web of the
channel is the walking surface and has large debossed holes, surrounded by
smaller embossed traction buttons. The extended flanges support the load and
provide a built in kickplate (toeboard).
FEATURES & BENEFITS
• Embossed traction buttons provide superior slip resistance in all directions
and in all weather conditions.
• Large debossed holes provide maximum drainage of debris and allow up
to 50% free air opening depending on channel width.
• One-piece metal construction complete with a full 5” toe-board height on
each side of the walking surface.
• Simple and economical installation as walkways are self-framing.
Grating shall be “Safety-Grip® walkway,” manufactured from
(see ‘Selections’ below) and complete with an integral 5” toe-board,
by AMICO.
Selections
• ASTM-A-653, G-90 (Z-275) pre-galvanized 13 or 11 gauge steel.

Note:
• All uniform and concentrated loads include a safety factor
of 1.67.
• Area in bold outline–contact AMICO for recommendations.
• Strut deflection may become a limiting factor resulting in
lower load values as indicated in table.
TechnicaL Details
Note:
• Tolerances on all dimensions are ±1/8”
• Standard lengths are 120” & 144”.
• Tolerance on manufactured and cut lengths is ±1/8”.
• Nominal 36” walkway has a 34” walking surface.
36” dimension is to outside of return flange.
Camber is an expected condition with sheet metal products. While ASTM allowance is
generous, AMICO attempts to lessen the effects. Normal clearances should offset this
phenomenon, however where tolerances warrant, contact AMICO for clarification.

Safety Grating
Safety-tread® flooring
PRODUCT DESCRIPTION
Safety-Tread® is a metal flooring product which is covered with small
perforated dimples manufactured by a cold forming process.
Optional Feature:
Safety-Tread® flooring is available in two drainage patterns which incorporate embossed holes (staggered) between raised dimples.
FEATURES & BENEFITS
• Perforated dimples provide superior slip resistance in all directions and
in all weather conditions. The quantity of dimples under foot provides
exceptional adhesive friction.
• Can be easily formed into custom shapes.
• Adaptable to wide range of applications.
• Easily adaptable to cost effective, custom fabrication.
• Low projections and closed area provide an acceptable walking
surface for industrial as well as institutional and commercial
application (i.e., women in heels can walk comfortably and safely).
• Available in four dimpled patterns
• Optional drainage flooring features smaller unembossed holes
(location and size variable with dimple pattern) providing drainage for
liquid which may pool on walking surface in wet environments.

safety-Tread® LADDER RUNGS
Safety-Tread® ladder rungs are small channel shaped sections; the web of the channel being the walking surface which is covered with small perforated
dimples, produced by a cold forming process.
FEATURES & BENEFITS
• Perforated dimples provide superior slip resistance in all directions and in all weather
conditions. The quantity of dimples under foot provides exceptional adhesive friction.
• Cross sectional design provides significant load carrying capacity on spans up to 24”.
• Three widths of rung to choose from.
• Leading row of dimples projected on the edge of the rung provides slip resistance to the
foot approaching at an angle to the walking surface.
• Adaptable to a wide range of applications.
• Easily adaptable to cost effective, custom fabrication.
• Ideal for retrofit applications as rungs fit over slippery pipes, bars, etc. on existing ladders.
Ladder rungs shall be “Safety-Tread® ladder rungs,” manufactured from (see ‘Selections’ below) by AMICO.

Safety Grating
installation Accessories
SAFETY-GRIP® BOLT SEATS
Safety-Grip® planks can be mechanically
fastened to a structural support by using
specially designed Bolt Seats which seat
within the large debossed holes, below
the walking surface. Bolt Seats have
an oblong hole to accommodate a 3/8”
bolt, and are available in:
• 11 ga., G90 Galvanized (H12264)
• .125” Aluminum (H12264A)
• 316L Stainless (H12264S)
DIAMOND-GRIP® BOLT SEATS
Diamond-Grip® planks can be mechanically fastened to a structural support by
using specially designed Bolt Seats which
seat in between the raised diamonds
below the walking surface. Bolt Seats
have a round hole to accommodate a
3/8” bolt, and are available in:
• 12 ga., G90 Galvanized (H12262)
• .125” Aluminum (H12262A)
• Stainless (H12262S) by special
request only.
• Optional square hole in bolt seat to
accommodate 5/16” carriage bolt
available by special request (H12262SQ)
MID-SUPPORT CLIP ASSEMBLY
“J” CLIP ASSEMBLIES
Between structural supports it may be necessary to tie
planks together to minimize relative deflection. This is
accomplished by using a Mid-Support Clip which draws the
plank’s side channels together by applying pressure between
the bolts and the clip edge (clip no. MSCL).
In order to alleviate the necessity of drilling a hole through a structural member, a Bolt Seat and “J” Clip assembly can be used. The friction connection
is accomplished by wedging the grating between the Bolt Seat and structural
support, by applying pressure to the underside of the flange of the supporting steel (clip no. H12296). Not recommended in areas subject to vibration.

Fabricated Fiber-Reinforced Plastic
Grating, Platforms, Ladders and Railings
Fiberglass is an extremely versatile material and can be used in place of or in conjunction with aluminum, steel or stainless steel.
It is a high-strength, light weight, strong, corrosion-resistant material that is maintenance-free (it never rusts and never needs
painting). Other features that make AMICO-Seasafe fiberglass-reinforced plastic products desirable include slip-resistance, nonconductivity, fire retardancy, low thermal conductivity and UV protection.

GatorPlateTM and Covered Molded Grating
GatorPlate floor plate is perfect for fixing slippery spots or large slippery
areas. The anti-slip surface helps reduce slips and falls even when hazardous
liquids are present. Seasafe grating is available with GatorPlate attached to
the top for a smooth walking surface. Covered grating is used for odor control,
as well as for elevated walkways to insure that nothing drops thru the walkway onto the surface below.
NOTE: Covered molded grating has a varying degree of “out-of-flat.” In most
applications, this condition will require correction with hold down hardware.
81
GatorDeckTM Pultruded Grating
Slip-resistant surface
Pultrusion is a continuous molding process in which glass roving,
glass matting, and a synthetic surface veil are literally “pulled”
simultaneously through a flame-retardant polyester or vinylester
resin bath. Desired geometric shapes are formed and solidified as
they are pulled through a heated steel die. Seasafe’s GatorDeckTM
pultruded grating provides the ultimate combination of strength,
corrosion resistance, and structural integrity as a result of the
automated pultrusion process.

GatorGrateTM and GatorDeckTM Stair Treads
Cut your own stair treads from GatorGrate Stair Tread panels.
Ease of cutting – the panel design incorporates cutting “slots” every
six inches so treads can be cut inexpensively, quickly and accurately,
resulting in banded treads on both ends.
Economy – the 24-1/4” x 144” panel size offers numerous combinations to maximize the number of treads (less wastage = less cost).
Chemical Compatibility – A detailed table of chemical compatibility
for GatorGrate products based on resin manufacturers’ data is
available. To get a copy of this table, which provides maximum
allowable concentrations and temperatures, call us at 800-326-8842
or fax 337-406-8880 and ask for Seasafe Tech Support Bulletin #3.
Order to size stair treads made from GatorDeck.
It is helpful to identify Total Stair Run and
Total Stair Rise dimensions, as well as
intended Tread Rise when designing and
estimating stair systems.
Fiberglass Stair Tread Covers are a cost-effective
way to improve stairway safety for your workers. They are made
with corrosion resistant resin with a low flame spread rating. Panels
include an integral grit top surface and a woven fiberglass mat.

Fiberglass Cable Tray Systems
Why Specify Seasafe Cable Tray?
Since 1978, Seasafe Fiberglass Cable Tray
Systems have been tested and proven in
the harsh environment of the offshore oil
and gas industry, and are accepted by the
U.S. Coast Guard. Subject to the corrosive
conditions inherent in petroleum products,
plus the daily punishment of exposure to
wind, weather and saltwater, Seasafe
Cable Tray has stood up!
Seasafe Cable Tray gives you the load
capacity of steel plus the inherent charac-
teristics afforded by our in-house Pultrusion Technology: non-conductive, nonmagnetic and corrosion-resistant. Although
light in weight, their strength-to-weight
ratio surpasses that of equivalent steel
products. Seasafe Cable Tray will not rust,
nor does it ever require painting. Available
in both polyester and vinylester resin
systems, it is manufactured to meet ASTM
E-84, Class 1 Flame Rating and self-extinguishing requirements of ASTM D-635.
A surface veil is applied during the
pultrusion process to ensure a resin-rich
surface for superior corrosion resistance
as well as an ultraviolet exposure barrier.
Cable Tray comes in two standard colors:
gray (polyester resin) and beige (vinylester
resin). Custom colors are available
on request.

Expanded Metal
REGULAR EXPANDED METAL is a finished product as it comes from
the press after having been die cut and expanded. The illustration
shows that the strands and bonds form a sharp angle to the original
plane of the solid sheet.
FLATTENED EXPANDED METAL is a regular expanded metal which has
been cold rolled, leaving a flat, smooth surface. The length of the sheet
is elongated usually by 5% while the width stays the same.

Expanded Metal & Expanded Metal Grating
NOMENCLATURE
PRODUCT DEFINITION
BOND—The point where adjacent strands intersect. The bond is always
twice the width of the strand.
DECORATIVE EXPANDED METAL is manufactured with unique shaped
openings which possess great appeal for architects and designers.
CAMBER—Bow in sheet. It is measured by placing a straight edge along
the concave side of the sheet parallel to LWD, touching both ends of the
sheet. The maximum distance between the edge of the expanded metal
and the straight edge is the camber. A sheet may be within a width tolerance and still have camber.
C.S.F—(hundred square feet) the unit of measure for price and weight.
DISTRIBUTION—expanded metal products are readily available from large
stocks maintained by your local steel service center.
DIAMOND OR OPENING—This is the description of the open area formed by
strands and bonds. Normally the open area is diamond shaped.
FINISHING—Limited finishes can be accomplished at manufacturing
plants. This includes hot-dip galvanizing and pre-galvanizing.
FORMABILITY—Each piece should be able to withstand a 90 degree bend
with a 1/4 inch inside radius in either direction, without fracture.
FLATTENED EXPANDED METAL is manufactured by processing regular
expanded metal in a rolling mill. This rolling process reduces the thickness
of the sheet and provides a smooth flat sheet.
LEVELING—All expanded metal products except grating are leveled after
having been expanded.
LWD OR LWO—Long way of diamond or long way of opening is the
dimension measured across the sheet in a direction parallel to the largest
dimension of the diamond.
MESH—This is the nominal distance from the mid-point of one bond to the
mid-point of the next bond measured across the SWD. Mesh is expressed
in inches.
REGULAR EXPANDED METAL is sheet simultaneously slit and stretched
into a rigid, non-raveling open mesh. It is readily available in carbon steel,
aluminum and stainless steel.
SHEET SIZE—While expanded metal can be manufactured in many varying
sheet sizes, practical limitations are such that it is wise to select sheet
sizes shown in the catalog. Availability of sizes can be determined by
contacting your steel service center.
OPENING SIZE—The area enclosed by bonds and strands.
STAIR TREADS—Expanded Metal Grating Stair Treads are fabricated using
4.0# Grating, angles and bars. They are shipped ready for installation on
the job.
OUT OF SQUARE—Expanded metal sheets are generally not perfectly
square when finished. Sheets must be resquared by shearing on all sides
for perfect squareness.
Special finishing such as anodizing, enameling, and plastic coating can be
arranged by contacting your steel service center.
Reshearing at the mill is not usually done since most sheets are sheared
to size to be within tolerance.
PRODUCT SELECTION
OVERALL Height—This is the finished height and often determines the
selection of framing members.
PERCENT OF OPEN AREA—The relation of solid metal to open diamond
allowing light, liquids and air to pass.
PITCH—The measurement from a point on one diamond to the same point
on an adjacent diamond.
The first step in the design of a product or fabricated assembly incorporating expanded metal is to select the appropriate expanded metal pattern,
keeping in mind various product characteristics.
The strength and rigidity of expanded metal material is determined by
Long Way of Design. On a walkway, for example, the LWD should run
perpendicular to the walkway support.
Reverse diamond—Panels that have their long way diamond direction
coinciding with the short direction of the panel.
Diamond direction also affects air deflection and diffusion, concealment
properties and aesthetic appearance. Consult your supplier for suggestions.
STRAND—The single metal strip which forms the border of the diamond,
or opening. Strand width is the amount of material advanced for expanding
as differentiated from strand thickness which is the thickness of metal from
which the expanded metal is produced.
Most manufacturers can and do routinely furnish expanded metal in
special (“non-standard”) sheet sizes when requested. In this event, it
is important for the specifier to give some consideration to the edge
configuration of the sheet as it relates to any particular requirement since
the cost may be affected by the manufacturing operations necessary to
shear the edge desired.
STYLE—Is the guage or thickness of metal from which expanded metal is
made. Usually, but not always, this conforms to manufacturer’s standard
guages. Style is expressed by a number. Expanded metal grating style is
expressed in lbs. per square foot.
SWD OR SWO—Short way of diamond or short way of opening is the
dimension measured across the sheet in a direction parallel to the smallest
dimension of the diamond.
94
EXPANDED METAL GRATING is produced from heavier plate, usually lowcarbon steel, with larger diamonds. It is typically used for walkways and
platforms.
