Strong, Lightweight
and Corrosion-Resistant
Want the strength of steel without the weight? Our fiberglass-reinforced polymer (FRP) grating products
have the advantage. Our grating is corrosion-resistant, it’s fire-retardant, and it has low conductivity. It’s
available with anti-slip coating for worker safety. And it’s easy to install with standard tools.
Whether you need simple grating panels or a complete FRP system with handrails, stairs and platforms,
we have the solution to match. In addition to our products, we offer design, engineering and fabrication
capabilities to meet your project needs.

PROGrid® Molded Grating
Proven corrosion resistance is just one of the
benefits of our PROGrid® molded grating. It’s
strong, lightweight and performs reliably for
years, even in extreme conditions. Top surface
options also provide excellent slip resistance
for worker safety.
4
Long Service Life
The high resin-to-glass ratio (approximately 65% resin
to 35% glass by weight) provides excellent service life,
even in the most demanding applications.
Less Waste
Interwoven square mesh construction provides
bi-directional strength, so you can cut grating to fit
and make the most efficient use of each panel.
Standard Resin Systems
PROGrid® molded grating is available in three standard resin
systems, each providing different levels of corrosion protection.
All three resin systems meet Class 1 Flame Spread Rating per
ASTM E-84 test standards.

1. The following tables were developed in accordance with the test method developed by the Fiberglass Grating
Manufacturers Council (FGMC) of the American Composites Manufacturers Association (ACMA) for the Fiberglass
Grating Standard.
2. The designer should not exceed MAXIMUM RECOMMENDED load at any time. MAXIMUM LOAD represents a 4:1
factor of safety on ULTIMATE CAPACITY. ULTIMATE CAPACITY represents MAX LOAD observed at initial fracture.
3. Walking loads for maintenance traffic are typically a live load of 50 PSF. Deflections for worker comfort are
typically limited to 0.375" (3/8") or SPAN divided by 120 under full live load. For a firmer feel under full live load
or a line load 250 lbs/ft of width, limit deflections to 0.25" (1/4") or SPAN divided by 200.
4. The loads represented are for STATIC LOAD CONDITIONS at ambient temperature. Deflections for impact loads or
dynamic loads will MULTIPLY the deflections shown by 2. Long term loads will result in added deflection due to
creep in the material and will require higher factors of safety to ensure acceptable performance.
5. Deflections are limited to 0.5" (1/2") as recommended by the Fiberglass Grating Manufacturers Council of the
American Composites Manufacturers Association.1” x 1” x 4” Rectangular Mesh

PROGrid® High Load Capacity Molded Grating (HLC)
PROGrid® High Load Capacity (HLC) molded grating is high-strength,
corrosion-resistant and low-maintenance — just like our PROGrid® molded
grating products. Plus, it’s engineered to carry higher loads than traditional
grating. Our molded HLC grating is available in 4' x 6' panels with 1.5"
and 2" thicknesses and comes in GPFR, IFR and VFR resin systems in
standard gray.
Standard Resin Systems
PROGrid® HLC molded grating is available in three
standard resin systems, each providing different levels
of corrosion protection. All three resin systems meet
Class 1 Flame Spread Rating per ASTM E-84 test
standards.
GPFR: A general-purpose orthophthalic polyester resin
system that offers good corrosion resistance at an
economical price.
IFR: A premium-grade isophthalic polyester resin
system that provides excellent corrosion protection.
VFR: A vinyl ester resin system that provides the
highest level of corrosion protection.

Allowable Spans for Vehicular Loads NOTES :
1. Load is carried by the grating load bars immediate under wheel + four additional load bars
adjacent to wheel.
2. Allowable Span is based on a 0.25" maximum deflection and a Factor of Safety of 3.0. Other
criteria may be required by certain construction codes. Check code requirements to determine
design criteria.

3.ALLOWABLE SPAN IS STRONGLY DEPENDENT ON WHEEL WIDTH AND VEHICLE WEIGHT/
LOAD CAPACITY. If your application varies from the values given on this table, contact us for
application assistance.
4.Load based on the AASHTO Standard Truck Load as defined in AASHTO LRFD Bridge Design
Specifications, 2nd Ed. This does not imply that the allowable span meets the deflection

PROGrid® High Load Capacity Molded Grating Load and Deflection Data
Concentrated Load
1. These tables were developed in accordance with the test method developed by
the Fiberglass Grating Manufacturers Council (FGMC) of the American Composites
Manufacturers Association (ACMA) for the Fiberglass Grating Standard.
2. The designer should not exceed MAXIMUM RECOMMENDED load at any time.
MAXIMUM LOAD represents a 4:1 factor of safety on ULTIMATE CAPACITY.
ULTIMATE CAPACITY represents MAX LOAD observed at initial fracture.
Equal
3. Walking loads for maintenance traffic are typically a live load of 50 PSF.
Deflections for worker comfort are typically limited to 0.375" (3/8") or SPAN
divided by 120 under full live load. For a firmer feel under full live load or a line
load 250 lbs/ft of width, limit deflections to 0.25" (1/4") or SPAN divided by 200.
Equal
SPAN (in.)
Uniform Load
4. The loads represented are for STATIC LOAD CONDITIONS at ambient temperature.
Deflections for impact loads or dynamic loads will MULTIPLY the deflections shown
by 2. Long term loads will result in added deflection due to creep in the material
and will require higher factors of safety to ensure acceptable performance.
5. Deflections are limited to 0.5" (1/2") as recommended by the Fiberglass Grating
Manufacturers Council of the American Composites Manufacturers Association.

PROGrate® Pultruded Grating
PROGrate® pultruded grating supports heavier
loads and longer spans than comparably
sized molded grating. It’s ideal for demanding
applications ranging from ADA-compliant
walkways to heavy-duty vehicular traffic.
Easy Fabrication
Strong, Lightweight and Corrosion-Resistant
VGBA Certified
Our pultruded grating has the strength of steel, but it
won’t corrode like steel can.
Safer Walking Surface
A coarse epoxy coating enhances traction.
Support and Stability
Cross-rods and bearing bars lock mechanically for
maximum unidirectional strength.
12
Panels are lightweight, easy to transport, and can be cut
and fabricated using standard hand tools.
Extended Life
The coated resin surface increases resistance to
chemical corrosion and continuous UV exposure.
Our pultruded FRP grating has been tested and has met
the specifications set forth by the Virginia Graeme Baker
Act (VGBA) for use in VGBA compliant drain systems.
Stress Resistance
Continuous glass rovings resist tension, compression
and bending while providing longitudinal strength.
Continuous glass mat increases transverse strength and
resistance to impact.

PROGrate® Heavy Duty Pultruded Grating (HDP)
PROGrate® Heavy Duty Pultruded (HDP) grating is engineered
to carry higher loads than traditional grating. It also delivers
the same high-strength, corrosion-resistant performance as
our PROGrate® pultruded grating products. Our HDP grating is
available in 1", 1.5", 2" and 2.5" thicknesses and comes in IFR
and VFR resin systems in standard gray. Made-to-order panels are
available up to 5' wide by 20' long.
Standard Resin Systems
APPLICATIONS
Flooring, platforms and ramps
Storage areas
Assembly lines
Long-span walkways
Trench covers with vehicular
traffic
PROGrate® HDP grating is available
in two standard resin systems,
each providing different levels of
corrosion protection. Both resin
systems meet Class 1 Flame
Spread Rating per ASTM E-84 test
standards.
FEATURES
High strength
Corrosion resistant
Low conductivity
Fire retardant
Low maintenance
IFR: A premium-grade isophthalic
polyester resin system that provides
excellent corrosion protection.
VFR: A vinyl ester resin system
that provides the highest level of
corrosion protection.

Allowable Spans for Vehicular Loads NOTES :
1. Load is carried by the grating load bars immediately under wheel + two additional
load bars.
2. Allowable span is based on allowable bending stress and 0.25" deflection; other criteria
may be required by certain construction codes. Check code requirements to determine
design criteria.
Allowable Span in Inches
3.Allowable span is strongly dependent on wheel width and vehicle load
capacity. If your application varies from the values shown on this table, contact us for
assistance.
4.Load based on AASHTO LRFD bridge design Specification, 2 Ed. This does not imply that
the allowable span meets the deflection requirements of this specification.

PROGrate® Heavy Duty Pultruded Grating Load and Deflection Data
1. These tables were developed in accordance with the test method
developed by the Fiberglass Grating Manufacturers Council (FGMC) of
the American Composites Manufacturers Association (ACMA) for the
Fiberglass Grating Standard.
Concentrated Load
12”
SPAN
Uniform Load
12”
SPAN
2. The designer should not exceed MAXIMUM RECOMMENDED load at any
time. MAXIMUM LOAD represents a 2:1 factor of safety on ULTIMATE
CAPACITY. ULTIMATE CAPACITY represents MAX LOAD observed at
initial fracture.
3. Walking loads for maintenance traffic are typically a live load of 50
PSF. Deflections for worker comfort are typically limited to 0.375"
(3/8") or SPAN divided by 120 under full live load. For a firmer feel
under full live load or a line load 250 lbs/ft of width, limit deflections
to 0.25" (1/4") or SPAN divided by 200.
4. The loads represented are for STATIC LOAD CONDITIONS at ambient
temperature. Deflections for impact loads or dynamic loads will
MULTIPLY the deflections shown by 2. Long term loads will result in
added deflection due to creep in the material and will require higher
factors of safety to ensure acceptable performance.
5. Deflections are limited to 0.5" (1/2") as recommended by the
Fiberglass Grating Manufacturers Council of the American Composites
Manufacturers Association.

VGBA Certified & Food Grade Products
PROGrate® pultruded FRP grating has been tested
and has met the specifications set forth by the
Virginia Graeme Baker Act (VGBA) for use in
VGBA compliant drain systems.
An independent test laboratory has tested PROGrate®
pultruded grating in accordance with ASME A112.19.8.a
– 2008, section 3.2 (Ultraviolet Light Exposure), which
includes ASTM D256 for izod impact and ASTM D638 for
tensile strength after being subjected to accelerated UV
weathering.
PROGrate® WT 10-18, I 10-40 and I 15-40 are ideal for
fabricating VGBA-compliant drain systems around
pools and spas.
Completed test results have shown that PROGrate® grating
has a K factor of 1.1 when calculated from section 3.2.2.3
(Performance Requirements) of the ASME A112.19.8.a –
2008 specification, which is the test method for grating
covering pool drains. All of our FRP grating products are
available as stock panels or can be fabricated to size.

FOOD-GRADE APPLICATIONS
We also offer PROGrid® molded and PROGrate® pultruded
grating for food processing applications. These products
are manufactured using a premium food-grade polyester
resin that contains no harmful ingredients and is certified
by the resin manufacturer. In addition, each panel is postcured and detergent-washed prior to shipping.
We certify that our food-grade PROGrid® molded and
PROGrate® pultruded FRP grating products are acceptable
for use in all food and beverage processing facilities, when
properly installed and maintained as an ergonomic or antislip walking floor surface or covering. These products meet
USDA acceptance requirements for floor surfaces.
Previously, the USDA tested all materials and products
that were in any way deemed a possibility for incidental
food contact in food processing facilities. Letters of
Acceptance were issued for tested, approved products.
According to Appendixes A and B of the National Register
(Sept. 1995), the USDA has limited its scope for the
testing of construction materials that were in obvious
contradiction to the original ruling and no longer issues
Letters of Acceptance. Floor and wall materials should at
no time come in contact with food products during the
manufacturing process and therefore need not be tested
for intended food contact.
Our PROGrid® molded and PROGrate® pultruded products
are designed to be installed only as worker ergonomic or
anti-slip floor grating, and we have issued this statement
as a guarantee of suitability of material for this use in food
processing facilities.
PROGrid® Molded & PROGrate® Pultruded
Phenolic Grating
PROGrid® molded and PROGrate® pultruded phenolic grating
products are the ideal solution for decks, platforms, stairways and
walkways that require superior resistance to fire,
as well as low levels of smoke and toxic gas emissions. Our
phenolic grating products are manufactured to the highest
quality standards using fiberglass reinforcement and a phenolic
resin system. These products are USCG level 2 approved.

PROGrid®/PROGrate® Phenolic Grating Load and Deflection Data
1.These tables were developed in accordance with the test method developed by the Fiberglass Grating
Manufacturers Council (FGMC) of the American Composites Manufacturers Association (ACMA) for the
Fiberglass Grating Standard.
Concentrated
Load
2.The designer should not exceed MAXIMUM RECOMMENDED load at any time. MAXIMUM LOAD
represents a factor of safety of 4:1 for PROGrid® molded grating and 2:1 for PROGrate® pultruded
grating on ULTIMATE CAPACITY. ULTIMATE CAPACITY represents MAX LOAD observed at initial fracture.

SPAN (in.)
3.Walking loads for maintenance traffic are typically a live load of 50 PSF. Deflections for worker comfort
are typically limited to 0.375" (3/8") or SPAN divided by 120 under full live load. For a firmer feel under
full live load or a line load 250 lbs/ft of width, limit deflections to 0.25" (1/4") or SPAN divided by 200.
