PERF-O-GRIP Grating
General Information
PERF-O GRIP™ Safety Grating
PERF-O GRIP safety grating’s unique surface of large
debossed holes and perforated buttons helps provide
maximum slip protection and performance under
practically all conditions and in every direction.
The large debossed holes allow fluids, mud, chips and
other debris to drain away. With 5 inch high side channels,
PERF-O GRIP Walkways meet OSHA requirements for
toeboards on elevated structures. Canadian OH & S
compliant designs are also available.
In addition to providing safety, the resilient surface of
PERF-O GRIP grating cushions the impact of footfalls
thereby lessening worker fatigue and increasing efficiency.
PERF-O GRIP safety grating is your best safety buy. It helps
cut cost and improve plant productivity.
Fast Installation
Light, easy-to-handle planks make installation simple and
quick. They can be handled by one person. Most sections
are rapidly bolted, clamped or welded into place, easily
field cut at virtually any angle, or fabricated to adapt to field
conditions.
Attachment devices permit fastening to most existing
surfaces, allowing for fast installation and disassembly.
Economical To Install and Use
In addition to offering a lowest total installed cost,
PERF-O GRIP safety grating also features long-lasting,
rust- resistant materials and finishes. Standard millgalvanized finish resists corrosion to provide lasting
surfaces. High-strength aluminum, Type 316-2B and
Type 304-2B stainless steels are available to provide
maximum corrosion resistance. Plain unpainted steel
(HRP&O) is available for those installations requiring paint.
Lightweight but brawny panels permit substantial reduction
in structural steel requirements.
PERF-O GRIP 2 Safety Grating
We offer a second style of PERF-O GRIP grating.
PERF-O GRIP 2 safety grating features 115/16” on center
hole spacing (compared to 2” on the original style). In
addition, PERF-O GRIP 2 safety grating can be produced
with safety end margins on its 2-hole (5” wide) through 6
hole (12” wide) plank and without end margins on its
10-hole (18” wide) through 16-hole (30” wide) plank. The
original PERF-O GRIP is still available in 2-hole (5” wide)
through 16-hole (30” wide).
Versatility
A variety of standard widths and channel heights are
available as well as numerous non-standard shapes and
sizes to meet almost any requirement of strength, size,
durability, weight, finish, appearance and application.
PERF-O GRIP safety grating combines safety and durability
with ease of fabrication and versatility. One-piece
construction — no welds or rivets to fail — minimizes need
for field fabrication. Special shapes and forming can be
accomplished to suit unusual requirements.
All surfaces are accessible to brush or spray, making it
simple and economical to apply finish coatings.
PERF-O GRIP safety grating may be hot dipped galvanized
after fabrication, anodized, plated, plastic-coated or
otherwise finished to suit job requirements. Standard
PERF-O GRIP plank is available in materials and sizes to
meet most load/span requirements. May be used as is, or
banded, cut, welded or notched to suit requirements.
PERF-O GRIP 2 plank with its safety end margins is stocked
in 5”, 7” 10” and 12” widths and in 10’-0” (1201/8”) and
12’-0” (144”) lengths. PERF-O GRIP plank is stocked in
18”, 24” and 30” widths, in 10’-0” (120”) and 12’-0” (144”)
lengths. Other lengths can be manufactured per order
requirements. Standard metals are 11 gauge and 13 gauge
carbon steel (mill-galvanized), 16 gauge stainless steel
(Type 316-2B to 12” wide), and .125” aluminum. PERF-O
GRIP can also be manufactured in HRPO steel and
stainless steel (Type 304-2B) on special order.
Safe Surface
Grips soles securely — in all directions. Non-slip
PERF-O GRIP safety grating surfaces are ideal for inside or
outside locations where mud, ice, snow, oil and detergents
can create hazardous walking conditions.
The circular openings (38% of surface area depending on
product size) are small enough to catch most falling tools
and other dangerous objects. But the self-cleaning open
design permits quick drainage of fluids, chips, grease and
mud while permitting ventilation and lighting flow. Ice
accumulation shears easily under normal foot pressure.
Open design allows convenient access for cleaning.
PERF-O GRIP is easily cleaned with brush, liquid or air
spray if desired.
Helps Extend Life
PERF-O GRIP safety grating offers a high load capacity,
long-life, and high strength-to-weight performance; which
is achieved through depth of section and structural design.
Formed 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.

produce, as shown in Example A. 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.
How To Read Load Tables
™
To select the proper size of PERF-O GRIP grating,
determine load, clear span and deflection requirements
by first determining your loading requirements.
Example A
What deflection will a 300 lb. midspan concentrated load
produce on a plank spanning 5’-0” (part number P133011 page 11)?
Example — Clear span of 4’-0” with a concentrated load
requirement of 600 lbs. at 0.25” maximum deflection, for a
10’-0” wide plank; Refer to the 5-Hole Plank (10” Width),
then locate the Clear Span subheading for 4’-0” to find the
first occurrence of 600 lbs. (or greater) Concentrated Load
(C). In this example, the 13 gauge, 2” depth product (part
number P52013) carries a load of 648 lbs. with a 0.10”
deflection. While this is one product which meets the
minimum requirements, other options might be selected to
carry greater loads. For economical selection, choose the
greatest width that will support the load consistent with
job requirements and choose deeper channels rather than
heavier steel gauges.
C = 1517 lbs.
D = 0.09”
D @ 300 lbs. = 0.09” x (300 lbs. ÷ 1517 lbs.) = 0.02 inches
Example B
If a plank (part number P132011 - page 11) is spanning
7’-0”, what midspan concentrated load will produce a
.25” deflection?
C = 598 lbs.
D = 0.27”
C @ .25” = 598 lbs. x (0.25” ÷ 0.27”.) = 554 lbs.
How Load Tables Were Prepared
The values shown in the following tables are based on
actual load tests. The tables have been prepared in
accordance with the provisions of the AISI Specification
for the Design of Cold-Formed Steel Structural Members,
1986 edition.
Special Note On Planks
As width increases, grating surface performance
becomes more critical. Thus, for PERF-O GRIP product
widths greater than 12”, use of the grating surface splice
kit is recommended to mechanically join butt ends of plank
sections.
These load table values are based on consideration of
side channel flexure only and do not consider grating
surface performance. Side channel flexure occur when
the channels at midspan of 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 1 and 2). To
approximate the most severe condition, there were no
attachments between the channels and the supports.
Load - C
Deflection values indicated in the tables are the midspan
side channel deflection produced when the allowable
uniform or allowable concentrated load is placed at
midspan. Load data is based on yield strength of 33,000 psi
for steel, 27,000 psi for aluminum, 35,000 psi for Type 304
stainless steel, and 30,000 psi for Type 316-2B stainless
steel.

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

1. Align PERF-O GRIP planks on I-Beam or other
anchoring cross-member.
2. Mark the I-Beam for drilling purposes under the
PERF-O GRIP hole nearest the end. Drill a pilot hole.
3. Remove PERF-O GRIP plank and drill a finish hole.
4. Replace PERF-O GRIP plank to its original position.
Place bolt seat in the PERF-O-GRIP hole which is
now lined up with the drilled hole.
5. Run the carriage bolt through the bolt seat,
PERF-O GRIP and I-Beam, and tighten with washer
and nut until secure.
6. Test for movement or slippage. If PERF-O GRIP
planks are not secure, check fastening system for
loose or missing parts. Repeat steps 1 thru 5.
Note: Do not walk on PERF-O GRIP planks if
they are not secure. Serious injury could result.
Welding
A common method of fastening safety grating is
welding. It is recommended that all B-Line Safety
Grating products be fillet welded per AWS D1.3.

Specifications - PERF-O-GRIP™
Notes to architect
1. PERF-O GRIP and PERF-O GRIP 2 gratings are intended for general purpose use in plants and process facilities by
industry, commerce, and public utilities, and on air, water, and surface, for both mobile and stationary equipment.
2. PERF-O GRIP and PERF-O GRIP 2 stair treads are intended for utility stairs and fire escapes in commercial, public and
private buildings where local code permits. They are not intended for staircases used regularly by the general public
where flat closed surfaces are desired. For this type of application, see TRACTION-TREAD™ stair treads and sheets.
3. These specifications are presented as a general guide to the architect or structural engineer in preparing project
specifications. Allowable loads, spans and other limiting conditions presented in this catalog offer product data for use
in design and construction.
4. All supports should provide a smooth, level, 11/2” minimum bearing surface, free of burrs, bridging, welds or other
irregularities.
5. Random cut ends and diagonal or circular cut exposed edges should be banded with a bar at least 1/8” thick and equal
to the overall side channel depth of grating welded at contact points at the discretion of the design engineer.
6. Bolted connections, except stair or ladder tread attachment to stringer channels, may be replaced by welded
connections that develop the same strength.

Part 3: Execution
3.1 Condition of surfaces
Prior to grating installation, contractor shall inspect supports for correct size, layout and alignment and verify that
surfaces to receive grating are free of debris. The contractor shall report to the design or consulting engineer or
owner’s agent in writing any defects considered detrimental to proper application of grating so defects can be
remedied before grating is applied.
3.2 Grating installation
Install grating in accordance with manufacturer’s recommendations and shop drawings. Position grating sections
flat and square with ends bearing min. 11/2” on supporting structure. Keep grating sections at least 1/4” away from
vertical steel sections and 1/2” from concrete walls. Installation clearances are built into this product. Allow
clearance at joints between sections of max. 1/4” at side channels and max. 3/8” at ends. When specified, band
random cut ends and diagonal or circular cut exposed edges with a min. 1/8” thick bar welded at contact points.
3.3 Grating attachment
Attach grating to supports without warp or deflection as follows:
a. Single plank application: Secure plank ends to supporting members at every point of contact. Use(2) PERF-O GRIP
Bolt Seats or “J” Clip Assemblies at each end or secure both side channels at each end to supports by fusion
welding with 1/8” fillet welds, 1” long.
b. Multiple plank application: Secure perimeter plank to supporting members at every point of contact and
intermediate grating sections with at least (1) attachment each end of plank, on alternate sides. For added rigidity
when span exceeds (6’-0”) (8’-0”), attach side channels of adjacent plank together (at mid-point of span) using mid
support clip.
c. 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” o.c. staggered top and bottom.
d. Clip attachment: Secure intermediate planks to supports using Bolt Seat and “J” Clip Assembly. Use Bolt Seat
with 3/8” carriage bolts and nuts for securing perimeter planks. Fasten adjacent side rails together with mid
support clip or 3/8” machine bolts and nuts through locally drilled holes.
3.4 Stair Tread Installation
Install PERF-O GRIP and PERF-O GRIP 2 stair treads as shown on the drawings. Fasten treads to stair stringers with
3
/8” x 1” machine bolts and nuts.
a. For stair treads, intermediate stringer is recommended for spans over 4 feet.
