Safer, serrated surface
Grips soles securely in all directions. The non-slip GRIP STRUT
surface is ideal for inside or outside locations where mud, ice,
snow, oil and detergents can create hazardous walking
conditions. Openings are small enough to catch most falling
tools and other dangerous objects.
Open design, convenient cleaning
Permits quick drainage of fluids, chips, grease and mud. Any
ice accumulation shears easily under normal foot pressure.
Open design allows convenient access for cleaning, and is
easily cleaned with brush, liquid or air spray to help minimize
overall maintenance.
High load capacity, long life
High strength-to-weight performance is achieved through
depth of section and structural design. Bridged struts with
integral side channels form a plank that can support loads with
minimum transverse and longitudinal deflection. There are no
rivets or pressure joints to break or loosen. This sturdy
construction provides the advantages of heavy load-carrying
capacity with minimal deflection; rugged durability with
longer-lasting performance.
Fast Installation
Light, easy-to-handle planks make installation simpler and
quicker. They can be handled by one man. Most sections are
rapidly bolted, clamped or welded into place, easily field-cut at
virtually any angle, or fabricated to adapt to field conditions.
Several attachment devices permit fastening to most existing
surfaces; allow fast installation or disassembly.
Economical to install, use
In addition to low material cost and nominal erection cost,
GRIP STRUT™safety grating also helps save with its long-
lasting, rust-resisting materials and finishes. Standard mill-
galvanized finish resists corrosion to provide lasting surfaces.
High-strength aluminum and Types 304 and 316L stainless steel
are available to provide maximum corrosion resistance. Black
unpainted steel available for installations requiring hot dipped
galvanized finish after fabrication. These light weight but
brawny panels permit substantial reduction in structural steel
requirements. Open design is self-cleaning and virtually
maintenance free.
Versatile in application
A variety of standard widths and channel heights combine
with numerous non-standard shapes and sizes to meet almost
any requirement of strength, size, durability, weight, finish,
appearance and application. GRIP STRUT safety grating
combines safety and durability with ease of fabrication and
versatility. One piece construction with no welds or rivets to
fail, minimizes need for plant fabrication. Special shapes and
forming can be accomplished to suit unusual requirements.

Tested by an independent laboratory for slip resistance
according to standards and methods established by Federal
Specifications RR-G-1602D, GRIP STRUT™safety grating
exceeds all requirements of this specification.
• The standards where exacting - five shoe sole materials
tested in three directions under five conditions: dry, greasy,
muddy, soapy and icy. GRIP STRUT safety grating tested
more slip-resistant than similar materials, depending
on shoe materials and surface conditions.
In survey after survey, accidents caused by falls are high on
the list of disabling and lost-time injuries and death. In fact,
statistics from many states rate this type of accident second as
the cause for industry’s loss of manhours and lower productivity.
As proved in the test described above, GRIP STRUT safety
grating substantially reduces this kind of accident. In addition,
the hazard of falling objects is minimized by the shape and size
(17/8” x 11/16”) of the surface openings.

the plank deflect relative to support points. To verify the
performance of the side channels, samples were loaded with
concentrated and uniform loads at different spans (see Figures
1b/2b and 1c/2c). To approximate the most severe condition,
there were no attachments between the channels and the
supports. In cases where spans are shorter, channels deeper
and planks wider, strut flexure becomes more critical.
2-, 3-, 4- and 5-Diamond Allowable Load and
Deflection Tables
Since 2- through 5-Diamond planks are relatively narrow (less
than 1 foot wide), it can be assumed that both side channels
effectively support the concentrated load and that the grating
surface deflection is negligible. Based upon these assumption,
the values in the following Design Tables for 2-Diamond through
5-Diamond have been determined.
Allowable Uniform Load (U)
Values indicated in the rows adjacent to “U” are the lowest of
the (1) maximum allowable uniform loads considering channel
flexure and (2) maximum grating surface flexure.
Deflection Corresponding to “U”
Deflection values are indicated below the uniform loads and
are in the mid-span side channel deflections for the planks
carrying the allowable uniform loads (Figure 1c and 2c).
Allowable Concentrated Load (C)
Values indicated in the rows labeled “C” are the lowest of the
(1) maximum allowable concentrated load considering channel
flexure (Figure 1b and 2b), with both channels effective, and (2)
the maximum allowable strut load (Cs) for a 1 foot long sample
(Figure 1a and 2a).
Deflection Corresponding to “C”
Deflection values indicated below “C” values in the tables are
the mid-span, side channel deflections produced when the
allowable concentrated load is placed at mid-span.
If grating surface deflection should be considered when
selecting a product to meet a particular specification, then the
deflection of the mid-width of the grating, relative to the side
channels, can be calculated using both the data in the Strut
Loading Tables (pages 6 -17) and the Load/Deflection
Conversion formula on top of following page.
Load data based on yield strength of 33,000 psi for steel, 23,000
psi for aluminum, 35,000 psi for Type 304 stainless steel, and
30,000 psi for Type 316L stainless steel.
How To Read Load Tables
To select size of GRIP STRUT™safety grating, determine
load, clear span and deflection requirements. Having this
information, select from load tables the appropriate plank to
meet job requirements.
Example: Clear span of 4’-0”, concentrated load requirement of
300 lbs. at 0.25” maximum deflection.
Select from the tables following:
For 8-diamond, 183/4” wide, 21/2” channel, 12 gauge steel which
carries a load of 416 lbs. at a 0.18” deflection. This is one size to
do the job. Other sizes will carry more load if necessary. For
more economical selection, choose the greatest width that will
support the load consistent with job requirements and choose
deeper channels rather than heavier steel gauges.
GRIP STRUT safety grating will generally carry the same
concentrated load, tabulated in lbs. at midspan, for a given
span, material gauge and channel height, regardless of width.
(See “How load tables were prepared” described below.) The
uniform load tables are tabulated in lbs./sq.ft., which accounts
for the difference in load capacity shown for various widths.
Deflection is in inches.
How Load Tables Were Prepared
The values shown in the following tables are based on actual
load tests conducted in accordance with the provisions of the
AISI Specification for the Design of Cold-Formed Steel
Structural Members, 1986 Edition. To help ensure the safety of
the tabulated loads, two aspects of GRIP STRUT safety grating
must be considered.
The first consideration is transverse bending in the grating
surface, which is referred to as “strut flexure”. This occurs
when the grating is loaded with either a uniform load or a
mid-width concentrated load, and the “struts” (grating
surface) deflect relative to the side channels. To determine the
allowable strut loads, samples of each grating material and
thickness were tested for each plank width. (See Figure 1a
below and 2a on the following page). The data resulting from
these tests was used to prepare “strut loading” tables, which
give allowable loads and deflections considering strut flexure
only. These allowable strut loads, along with the results of
additional tests performed on 8- and 10-Diamond grating, have
been incorporated in the Product Selection/Design Tables on
pages 6 through 17.
The second aspect of GRIP STRUT safety grating strength is
channel flexure. This occurs when the channels at mid-span of

GRIP STRUT
Load/Deflection Conversion Formulas
In the elastic range, deflection is proportional
to the applied load for both uniform and
concentrated loads. This relationship can be
used to determine the deflection that any load
which is less than the allowable load will
produce, as shown in Example A. Also, if
desired, the load which will produce a specific
deflection can also be determined if the load is
in the elastic range as illustrated in Example B.
The following values have been tabulated for 8-Diamond and
10-Diamond grating:
Allowable Uniform Load (U)
Values are given in the rows labeled “U” and are the lowest of
the (1) maximum allowable uniform loads considering channel
flexure, and (2) maximum grating surface flexure.
Deflection Corresponding to “U”
Deflection values appear in the rows labeled “D”, below the
“U” values, and are maximum deflections the allowable uniform
loads would produce. Maximum deflections will occur at
mid-span and mid-width and will be the sum of side channel
and grating surface deflections (Figure 1c and 2c).
Allowable Concentrated Load (C)
Values tabulated in the rows labeled “C” are the lowest of the
(1) maximum allowable concentrated load considering side
channel flexure (with one side channel supporting the entire
load — Figure 2b, and (2) the maximum allowable strut flexure
(Figure 2a).
Deflection Corresponding to “C”
Deflection values are indicated below “C” values in the table
and are deflections the allowable concentrated load will pro-
duce at mid-span and at the mid-width. The deflection is the
sum of side channel and grating surface deflections
8- and 10-Diamond Allowable Load and Deflection Tables
As width increases, grating strut flexure becomes much more
important. 8-Diamond and 10-Diamond products are wide
enough to require a change in the assumptions used to prepare
the 2-Diamond through 5-Diamond Product Selection/Design
Tables. No longer will it be assumed that both side channels are
equally effective in supporting a concentrated load. In fact, to
provide a high level of safety, one side channel will be required
to carry 100% of a concentrated load.
Also strut deflection for 8-Diamond and 10-Diamond products
may be significant. The most critical case occurs when a
concentrated load is located at mid-span and mid-width. To
determine how the struts perform under this loading, 3 foot
long samples of each material and thickness were tested. For
these tests the side channels were continuously supported
and loads were applied using a 1 foot long and 1 inch wide bar
placed parallel to the side channels at mid-width and at the
longitudinal center.
Results of these tests, included in the 8-Diamond and
10-Diamond Product Design Tables, proved the performance
of these materials when a concentrated load is applied at
mid-span and mid-width. If a concentrated load is to be applied
at mid-width at the end of a plank, consult the Strut Loading
Tables (pages 6-17).
Example A
What deflection will a 300 lb. concentrated load produce on a plank
(catalog number 103012) spanning 5”-0”?
See page 16 for item 103012 at a span = 5’-0” C = 480 lb. D =
D @ 300 lb. = 0.26”/480 lb. x 300 lb. = 0.16”
Example B
If a plank (catalog number 103012) is spanning 6’-0”, what concentrated
load will produce a 1/4” deflection?
See page 16 for item 103012 at a span = 6’-0” C = 400 lb. D = 0.26”
C @ 1/4” = 400 lb./0.26” x 0.25” = 385 lb.

Note
The data in these tables represents the performances of both
side channels ignoring grating surface performance. These
values are not to be used for product selection but should be
used when comparisons are being made with other products
whose published information does not include grating surface
performance.
For Product selection and Design Tables, see pages 6 through 17.
10-Diamond Plank & Walkway
24” Width
Load/Deflection Conversion Formulas
In the elastic range, deflection is proportional
to the applied load for both uniform and
concentrated loads. This relationship can be
used to determine the deflection that any load
which is less than the allowable load will
produce, as shown in Example A. Also, if
desired, the load which will produce a specific
deflection can also be determined if the load is
in the elastic range as illustrated in Example B.
Example A
What deflection will a 300 lb. concentrated load produce on a plank
(catalog number 103012) spanning 5”-0”?
See page 16 for item 103012 at a span = 5’-0” C = 480 lb. D = 0.26”
D @ 300 lb. = 0.26”/480 lb. x 300 lb. = 0.16”
Example B
If a plank (catalog number 103012) is spanning 6’-0”, what concentrated
load will produce a 1/4” deflection?
See page 16 for item 103012 at a span = 6’-0” C = 400 lb. D = 0.26”
C @ 1/4” = 400 lb./0.26” x 0.25” = 385 lb.

Reconditioning Material
Here’s the “safety first” way to re-do worn and unsafe floors
and stairs - resurface with non-slip GRIP STRUT™safety grating
reconditioning material (RM). GRIP STRUT safety grating is the
only product that gives 500 wall-to-wall teeth per square foot.
Serrated, diamond-shaped openings make GRIP STRUT safety
grating safer than conventional gratings — permit mud, oil,
grease and industrial waste to fall through, when used over
open floor materials such as bar grating. Even ice shears free
under normal foot pressure. Down-turned edges allow grating
to lie flat and secure over existing flooring. Consult distributor
for product specifications.
Other important GRIP STRUT safety grating advantages include:
easy field fabrication and fast, low-cost installation. RM
products available on special order in standard materials and
sizes.
Flat Stock Material
Flat Stock can be manufactured to specified dimensions of
flat metal on either or both sides. Consult your distributor for
specifications and availability.
Versatility in form and function for new or special products
Because of its light-weight plank design, GRIP STRUT safety
grating is easy to handle and economical to install. Most
sections can be handled by one man. Simply and quickly field-
cut with standard tools. Layout and erection goes quickly
because panels match perfectly. Various widths may be used
to suit space requirements.
Many variations of GRIP STRUT safety grating panels are
available to suit specific requirements. Special forming can
be accomplished to suit requirements not covered by the
standard panels. Consult your distributor for availability.

GRIP STRUT
Installation Recommendations
General Installation Recommendations
Recommended Clearance
Steel: 1/4” minimum is recommended at perimeter and 3/8” maximum at end joints. Maximum between panels is 1/4”; 1/8”
is generally used.
Concrete: Concrete form deflection calls for slightly greater perimeter clearance. 1/2” is recommended.
(Maximum between panels is 1/4”).
Bearing Surfaces
Recommended minimum bearing 11/2”. Surfaces supporting GRIP STRUT™safety grating must be smooth and level to
insure that adjoining sections provide a safe, even walking surface.
Permanent Installation
GRIP STRUT™safety grating is easily welded to supports for permanent installations. Channels are quickly welded
together between supports to provide uniform deflection in adjacent panels.
For welded-attachment, secure side channels to supports by fusion welding with 1/8” fillet welds, 1” long. Weld adjacent
planks together with 1/8” fillet welds, 1” long, 24” on center staggered top and bottom.
Install GRIP STRUT safety grating according to details as shown on individual job drawings, or as follows:
(1) Single width applications. Utilizing the anchoring device or weldings, attach GRIP STRUT safety grating plank at
every point of contact with supporting structure around perimeter of plank.
(2) Multiple width applications. Utilizing the GRIP STRUT safety grating anchoring device or welded as recommended
by A.I.S.I., attach grating plank around the perimeter at each point of contact with supporting structure. In field of
platform, attach plank to supporting structure with a minimum of one attachment at each end of plank on alternate
sides.
When span exceeds 8 feet, weld or bolt side channels of adjacent planks together at midpoint of span.
(When spans exceed 6 feet, consider similar treatment.)
