standard mesh bar grating
bar grating anatomy
Tru-Weld® Bar Grating
Standard Mesh
Tru-Weld bar grating is forge-welded, a system in which
Fisher & Ludlow was a pioneer. In this process the bearing
bars and cross rods are permanently forged together by heat
and pressure into a single unit construction, resulting in greater
strength per pound than mechanical assembly methods.
The twisted cross rods provide a non-slip walking surface.
What does “Type 19-4” Mean?
Bar grating
For applications where extremely slippery conditions prevail,
Serrated Tru-Weld offers a superior grip surface to the load
bearing bars.
Bar grating types are specified by bearing bar spacing
followed by cross rod spacing.
plain surface
In imperial measurements, bearing bar spacing is described
in sixteenths of an inch. Therefore, Type 19 has bearing bar
centers at 19/16 of an inch (or 1 3/16”). Type 15 has bearing
bar centers at 15/16”. Type 11 is at 11/16” etc. The second
number after the dash in the Type designation refers to
the cross rod spacing. Cross rods are available in either 4”
(standard) or 2” (special) spacings.
All bar grating Types may also be described in metric units.
Again, the first number represents the bearing bar spacing
on centers and the second number represents the cross
rod spacing, both units measured in millimeters. Therefore,
Type 30-102 Metric equals bearing bars at 30mm centers
and cross rods at 102mm centers. This is the metric equivalent
of Type 19-4.
serrated surface

Note: Although the special 2” (50mm) cross rod spacing does
allow for less open space on the grating surface, it does not
affect the load rating of the grating. The most economical
and readily available choice for bar grating selection is
Type 19-4 (Type 30-102 Metric).
Steel Bar Grating
Tru-Weld steel bar grating is the most popular product
manufactured by Fisher & Ludlow. Nearly all sizes in Standard
Mesh Type 19-4 (Type 30-102 metric) are readily available in
our warehouses or stocked on the shelves of our distributors.
Standard Mesh
Simplicity in design is surpassed by its versatility in usage.
From mezzanines, platforms, catwalks, and stairs to fences,
benches, racking shelves, and ventilation covers, Tru-Weld
Steel Bar Grating is by no means limited to the industrial
applications for which it was originally designed.
Available in bare steel, shop primed, or hot dip galvanized.

When ordering or specifying Tru-Weld Bar Grating,
please confirm:
Standard Mesh
• The Type of grating.
Type 19-4 (Type 30-102 Metric) is Standard.
• Bar Size
• Grating surface – serrated or plain top
• Finish – unpainted, shop primer, or hot dip galvanized
• Style and quantity of fasteners, if required.
Example: Fisher & Ludlow Tru-Weld bar grating Type 19-4,
1 1/4 x 3/16 serrated, galvanized.

bar grating
• Span Direction (Direction of bearing bars)
• Area to be covered and method of support
• Dimensions – indicate whether your dimensions
take clearances into account
• Indicate any banding, kick plate, or nosing requirements
• Shipping and tagging instructions
Standard Practices
Standard quantity measurements for invoicing
Invoicing area or net area for grating ordered to specific
dimensions without drawings will be based on length
by width of each panel, with no deductions for cutouts.
load table information
For grating supplied from a drawing, the invoicing area
shall be on the basis of gross floor area measured out
to out of grating, with no deductions for clearances.
The load table calculations used throughout this catalogue are
based on “single span” condition. The dimensions shown are
for a clear, unsupported span.
Any detailing and/or fabrication of grating by Fisher & Ludlow
will conform to the ANSI/N.A.A.M.M. Standards.
Field measurement
The Seller shall not be responsible for the actual dimensions
of construction work in the field, but shall be responsible for
the accurate fabrication of grating and treads in accordance
with plans and specifications, if applicable.

(Standard)
Tru-Weld standard treads with checker plate nosings are
cost effective, durable and self-cleaning. The checker plate
nosing insures maximum visibility and underfoot safety where
needed most.

Spans and loads in the pink shaded area exceed a deflection of 6mm for
uniform loads of 5kPa. Experience has shown that 6mm deflection is the
maximum deflection to give pedestrian comfort, but can be exceeded for
other types of loads at the discretion of the engineer.

tru-weld Stainless Steel Bar Grating
Tru-Weld Stainless Steel Bar Grating provides a long-term
durable grating solution for caustic atmospheres where
corrosion resistance and minimum carbide precipitation
are important considerations. Typical applications include
stairs and platforms within chemical production and storage,
food processing plants, and water and wastewater treatment
facilities. Your choice of 304, 304L, 316, or 316L Stainless
Steel grades are available.
Heat from the Electroforge welding process discolors the
surface of the stainless steel in the weld area. For this reason,
Tru-Weld Stainless Steel Bar Grating is best suited for
industrial uses where cosmetic appearance is not a factor.

When considering load conditions for stainless steel bar
grating, please apply the calculations in the table below
to the values shown in the carbon steel load tables on
pages 12 and 13.

special mesh bar grating
special mesh information
tru-weld Special Mesh Bar Grating
Tru-Weld Special Mesh Bar Grating offer a variety of close
or wide space mesh options to suit specific aesthetic or
functional bar spacing requirements.
Close Mesh
Advantages of the close mesh grating style include
greatly increased load bearing capabilities and prevention
of fall through by dangerous objects such as heavy tools
or equipment accidentally dropped from above.
close mesh
wide mesh
Wide mesh grating options are designed for applications
requiring additional openness of bar grating to minimize
buildup of snow, ice, or other debris.
Available in most 1/8” and 3/16” Steel and Stainless Steel
bar sizes and select Heavy Duty bar sizes.

Wide Mesh
Special Mesh
As with Tru-Weld Standard Mesh Bar Grating, Special Mesh
Bar Grating may be ordered with either plain or serrated
bearing bars. Similarly, panels are manufactured with a
standard 4” cross rod spacing but 2” cross rod spacing
is available.
*Special Mesh Bar Grating is a non-stocked specialty item.
For the most cost effective and readily available bar grating
option, choose Standard Mesh Type 19-4 (Type 30-102 Metric).

Heavy-Duty Steel Bar Grating
Steel Bar Grating with bearing bars thicker than 3/16” is
considered to be “Heavy Duty” and carries the designation
prefix “Type HD”. Available bar thicknesses are 1/4”, 5/16”,
and 3/8” in either a plain or serrated surface. Standard depths
range from 1” up to 4”, although larger sizes are available
upon request.

Aluminum Standard Mesh
Fisholow® Rectangular
and I-Bar Grating
Fisholow Aluminum Bar Gratings employ a unique interlocking
system that joins the bearing bars and cross rods together
in panels of exceptional rigidity and strength. Lightweight,
corrosion-resistant, non-sparking alloys are ideal for pedestrian
platforms in chemical, petroleum, and food processing plants.
Fisholow gratings is recommended in most water and waste
water treatment facilities and is becoming increasingly popular
for use in architectural building designs.
Fisholow Aluminum Bar Grating is available in two bar profiles:
Rectangular Bar and I-bar. Similar to Tru-Weld Steel Bar
Grating, Fisholow Rectangular Bar Grating is offered with
a plain or serrated surface. Fisholow I-Bar Grating produces
exceptional load ratings at a fraction of the weight of its
rectangular counterpart, and is designed with a slip resistant
corrugated surface on the top of each I-bar.

Both Rectangular Bar and I-Bar styles are available in special
mesh options.

aluminum Tread with aluminum
abrasive nosing (Special order)
Fisholow treads with standard corrugated angle nosing are
strong, lightweight, and self-cleaning. They are ideal for
applications requiring corrosion resistance, non-sparking,
and rust proof grating. The corrugated angle nosing insures
maximum visibility and underfoot safety where needed most.
For tread widths 9 3/4”, 10 15/16” & 12 1/8”, standard end
plate is complete with 2 slots. See “B” dimension in chart.

Spans and loads in the pink shaded area exceed a deflection of 6mm for
uniform loads of 5kPa. Experience has shown that 6mm deflection is the
maximum deflection to give pedestrian comfort, but can be exceeded for
other types of loads at the discretion of the engineer.

Spans and loads in the pink shaded area exceed a deflection of 1/4”
for uniform loads of 100 lbs/sq. ft. Experience has shown that 1/4”
deflection is the maximum deflection to give pedestrian comfort, but can
be exceeded for other types of loads at the discretion of the engineer.

Grip Span Walkway Channel
Grip Span Walkway channels offer the same slip resistant
properties and self-cleaning advantages of other Grip Span
planks with the added feature of having built in kick-plates
along both sides of the channel length. The 5” toe boards
are integral parts of the channel and prevent tools and other
materials from falling over the edge of a catwalk.

Shur Grip Walkway Channel
Walkway channels offer the same slip resistant properties and
self-cleaning advantages of other Shur Grip planks with the
added feature of having built in kick-plates along both sides
of the channel length. The 5” toe boards are integral parts of
the channel and prevent tools and other materials from falling
over the edge of a catwalk.
Available in 24”, 30”, and 36” wide options.
*For 30” and 36” wide walkway, width dimension refers
to total overall channel width. For 24” wide walkway,
width dimension refers to the walking surface width.

Molded FRP
molded Fibreglass reinforced plastic
(FRP) grating
Molded Fiberglass Reinforced Plastic (FRP) Grating is
manufactured in an open, heated mold. Continuous E-glass
fibers are interwoven in alternating layers while being
completely wetted out with thermosetting resin systems.
This continuous process produces an integral, one piece
construction which provides resilience and bi-directional
strength. Although the concave profile of standard plain
surface Molded FRP Grating provides excellent anti-skid
properties, an integral grit surface can be supplied for
additional slip resistance. Other benefits include:

FRP grating sheet size and lightweight construction permit
simple and economical installation. Fasteners, supports and
hold-down clips permit total flexibility in achieving the desired
configuration of the final installation.
Conventional hand tools such as a hack saw, sabre saw, band
saw or disc saw with metal cutting blade can be used to cut
grating on-site and to cut around special openings as required.
Cut ends should be treated with Edge Sealing Kits.
*Stocked at most warehouses in dark grey color, grit top or smooth top.

PULTRUDED FRP GRATING
Pultruded FRP Resins
Pultruded FRP Grating has all the benefits of Molded FRP
Grating including corrosion resistance, high strength to weight
ratio, and ease of installation. With its high fiberglass content
and I-bar or T-bar style bearing bars, Pultruded FRP Grating
has increased unidirectional strength and stiffness to
accommodate longer span conditions. Pultruded FRP Gratings
are offered in a variety of bar profiles and spacings, including
close mesh options that are designed for non-motorized wheel
traffic and ADA compliance.
Pultruded FRP grating is available in two resin bases –
Isophthalic Polyester and Vinyl Ester. Isophthalic Polyester
resin is ideal for most industrial applications and is available
in standard light grey, yellow, or green. Vinyl Ester resin offers
superior corrosion resistance and comes standard dark grey.
Both are fire retardant with ASTM E84 flame spread rating
Class 1:25 or less.
Pultruded FRP grating types
Custom colors are also available.

Pultruded FRP I-Bar Types
Standard panel sizes are 4’ x 20’ (1219mm x 6096mm),
however custom panel sizes are available.

Bar Grating Fastening Methods
fastening methods information
BAR GRATING fasteners
Type D Saddle Clip
(complete with stainless steel self tapping screw)
Type D Saddle Clip
(complete with C-clamp and bolt)
Our most common and cost-effective fastening method.
Simply pre-drill a hole into the supporting member and drive
in the self-tapping screw. Designed for use with Tru-Weld Type
19 and Type 15 bar grating only (in 1/8” and 3/16” bar sizes).
Eliminates the need to drill supports or have access beneath
the grating during installation. The C-clamp slides between
the bearing bars to clamp the flange of the supporting
member and is tightened from above using a hex-driver.
For use with Tru-Weld Type 19 and Type 15 bar grating only
(in 1/8” and 3/16” bar sizes).
Available in standard galvanized or bare steel and stainless
steel options.
Type D Saddle Clip
(complete with nut, bolt, and bottom clamp)
This combination allows for fastening grating without drilling
into the supports. The Type D Saddle Clip holds the grating
from the top as the bottom clamp is tightened under the
flange of the supporting member. Designed for use with
Tru-Weld Type 19 and Type 15 bar grating only (in 1/8” and
3/16” bar sizes).

For close mesh Type 11 and Type 9.5 grating, a square collared
clamping bolt can be inserted directly between the ends of the
bearing bars and fitted through a bottom clamp. The rounded
bolt head rests directly on the bearing bars eliminating the
need for a top saddle clip.
Available by special order in bare steel, galvanized, and
stainless steel.

expanded metal information
EXPANDED METAL
Expanded Metal is manufactured from carbon steel or
aluminum sheets that are simultaneously slit and stretched
to create diamond shaped openings. The original metal sheet
may be expanded as much as 4 times its original length,
but is sheared down to stock sheet sizes.
expanded metal
• Light weight and strength make expanded metal an
extremely versatile material
• Ideal for partitions, enclosures, barriers, filters, walkways,
grilles, and machine guards
• Available in Raised or Flattened styles in a variety of gauges
and opening sizes to fit any application
• Standard sheets in stock for immediate shipment
• Custom Shearing available
Raised Expanded Metal
Expanded Metal Terminology
• Short Way of Design (SWD)
Nominal dimension
• Long Way of Design (LWD)
Nominal dimension – When referring to a sheet size the
SWD is always referred to before the LWD. For example a
“4 x 8 sheet” is 4 feet in the SWD direction and 8 feet in
the LWD direction.
• Short Way of Opening (SWO)
• Long Way of Opening (LWO)
• Strand Thickness
Gauge thickness of the original base metal sheet prior
to expanding.
Expanded Metal sizes showing the abbreviation “R” are
considered to be Raised Expanded Metal.
• Strand Width
Amount of metal fed under dies to produce one strand.
Raised Expanded Metal is a finished product as it comes from
the press. The strands and bonds are set at a uniform angle to
the plane of the sheet. This gives added strength and rigidity,
as well as a skid resistant surface.
• Bond Shearing
Cutting expanded metal to size with the shear line falling
through the bonds. The result is an edge configuration of all
closed diamonds. For bond shearing the resultant dimensions
must be in a multiple of the full diamond dimensions.
Flattened Expanded Metal
Expanded Metal sizes with the abbreviation “F” are
designated Flattened Expanded Metal.
Flattened Expanded Metal has been cold rolled after the
expansion process to provide a smooth, flat, and level sheet.
The flattening process reduces the original gauge of the base
metal and the strand width increases slightly.
• Random Shearing
The shear line falls at random points on the diamond mesh
pattern. Edges are open and diamonds are not matched.
Random shearing is necessary when the required overall
dimensions are not a multiple of the full diamond dimensions.
Expanded Metal Grating
Fisher & Ludlow manufactures two sizes of Expanded Metal
Grating, 3 lb. Grating and 4 lb. Grating. This style of Raised
Expanded Metal is produced from heavier gauge carbon steel
plates. Expanded Metal Grating is ideal for pedestrian traffic
and applications requiring heavier loads or larger openings
than conventional expanded metal options.
