PUPI Crossarm Design Summary
PUPI Series 2200, 2000, 2500 and 3000 crossarm beams are 3 5/8 X 4 5/8 to fit standard hardware
for wood crossarms.

PUPI Series 4400 and 4000 crossarm beams are 4.00 X 6.00 with heavy walls and are designed for
extra heavy loading applications.

PUPI Series 1000 crossarm beams are 2.10 X 4.04 outside dimensions and are suitable for lower
cost, lighter weight applications.
Many PUPI tangent crossarms and deadend assemblies are offered with all mount hardware attached
at our factory for easy, low cost installation.
PUPI crossarms can be field drilled through the center line of each major axis when needed.
PUPI crossarms are attached to wood, steel, fiberglass or other poles consistent with the attachment
methods for wood crossarms.
PUPI crossarms are completely filled with a high quality, closed cell polyurethane foam. Our process
ensures a strong adhesive bond between the foam and the beam walls so that moisture or other
contaminants cannot penetrate the arm or travel along the foam/fiberglass interface.

PUPI crossarms are made with high strength polymer endcaps that are bonded to the crossarm ends
to fully seal the ends of the arms.

PUPI crossarm endcaps include the PUPI logo in bold letters and the year of manufacture.
PUPI crossarms are offered with our patented TorqueGUARDTM fiberglass inserts at all bolt attachment
holes to give by far the most crush-resistant fiberglass crossarms in the world. The narrow edge (the
direction of primary loading) of PUPI crossarms can withstand over 450 ft-lbs of torque loading applied
to high strength 5/8 or 3/4bolts without damage to the crossarms. This exceeds the torque exerted by
standard pole line hardware.
PUPI crossarms have projected field life exceeding 60 years.
REV01.2016
PUPI Crossarm Mechanical Testing
Mechanical testing of PUPI crossarms has been performed at several independent test facilities
including: EDM International, Fort Collins, CO; the Composite Materials Technology Center
(COMTEC) at Winona State University, Winona, MN; and PFS Corporation, Madison WI. EDM
specializes in testing services for the electrical power industry, COMTEC specializes in testing
fiber reinforced composite structures, and PFS specializes in testing wood structures. Published
strength and deflection data for PUPI crossarms are based upon extensive testing of PUPI arms
performed at these independent test facilities.
PUPI test beams are taken as random samples from standard pultrusion runs. 10 and 12
arm flexure tests have been conducted at EDM; 5, 8, and 10 arm flexure tests have been
conducted at COMTEC; pin torque tests have been conducted at EDM and COMTEC; and ASTM
D198 tests (test for solid wood crossarms) have been conducted at EDM and PFS. Crossarm
flexure tests for braceless tangents and deadends use PUPI mounts and attachment hardware.
Flexural test fixtures at EDM and COMTEC use two large I beams to support mounts for
attachments to eyebolts on each end of a crossarm. Tests are conducted by applying a vertical
load at a constant rate to the steel mount and measuring load versus deflection to beam
fracture. Load/deflection plots are essentially linear to the fracture point for all PUPI crossarms.
An example of a flexure test setup at COMTEC is featured below:
PUPI test methods closely replicate actual product service conditions. Test specimens are
drilled with the same hole configuration as in the final product, production mounts and beam
attachment hardware are used, and loads are applied at the same points as in the final product
application.
REV01.2016
PUPI Crossarm Resistance to
Ultraviolet Radiation
PUPI fiberglass crossarms are made with triple protection against environmental degradation:
1. Outer arm surface is our patented thermally-bonded SunGUARD UV resistant coating.
This extremely abrasion resistant polyurethane coating has demonstrated exceptional UV
resistance over 30 years in environments from hot wet tropical areas to frigid northern climates.
2. An ultraviolet-resistant polyester veil forms a resin rich surface under the bonded coating.
3. The entire PUPI resin system contains a broad spectrum UV inhibitor.
SunGUARD Coating
Geotek engineers have been manufacturing fiberglass structural products for outdoor applications since 1972. We
started coating fiberglass products for outdoor applications in 1973 and started shipping SunGUARD coated fiberglass
structures in 1982. Since that time, we have not had a single product failure of any SunGUARD coated product
anywhere in the world due to environmental degradation nor have we seen any measurable coating erosion over time.
- PUPI crossarms have resin rich synthetic veil surfaces and UV resin inhibitors PLUS our unique
thermally-bonded SunGUARD coating to give unmatched UV resistance.
Accelerated Testing of Resistance to Ultraviolet Radiation

The Rural Utilities Service, US Department of Agriculture specifies 2500 hours of accelerated testing
according to ASTM G53-96, now G154-12a. PUPI beams have been tested with QUV Accelerated Weathering
Testers at the Composite Materials Technology Center at Winona State University, an independent
testing facility. Results:
PUPI crossarms had no degradation in flexural strength, modulus, or deflection to failure after 2500 hours of
exposure and minimal lightening of coating color.
A more aggressive test of 10,000 hours of accelerated exposure to intense UV-B radiation
showed some lightening of the coating color and loss of gloss but minimal coating erosion with
no effects at all on the fiberglass structure.
Note: The QUV is a comparative test. The ASTM states in G151 for accelerated testing: Even though it is very
tempting, calculation of an acceleration factor (ASTM italics) relating x hours of a laboratory accelerated test to y
months or years of exterior exposure is not recommended.
Field Experience
At present, there are well over one million PUPI fiberglass crossarms installed in a wide variety of
environments including the hot and wet climates of Southern Florida and Southeast Asia, the hot and
dry environment of the Arizona desert and other Southwestern states and the frigid Northern areas of
Canada and Alaska.
With over 19 years of exposure in various natural environments, not a single PUPI beam has failed
due to environmental degradation.
In the most intense UV exposure environments, some lightening of the coating color may occur,
particularly on the top surface, but the coating remains intact.
- PUPI crossarms have projected service life well over 60 years.

PUPI SUNGUARD UV COATING
Protection from Ultraviolet Light Degradation
SunGUARD UV Coating South florida Testing

SunGUARD UV coatings used on PUPI crossarms are the first line of protection against ultraviolet light
degradation over long periods of time. The coatings are high temperature cured, two-component polyurethanes with
powerful ultraviolet light inhibitors to minimize UV degradation.
SunGUARD UV coatings are applied in-line during the fiberglass beam pultrusion process. Applying the coatings
directly onto the hot beams creates strong thermal bonding and high crosslink density resulting in extremely tough
and solvent resistant coatings.
SunGUARD UV coatings were developed jointly with a major US coating manufacturer. The coatings were tested
in the standard 45 degree angle exposure test to the South Florida sun for 4 years. Percent weight loss of one
mil films was then determined. These results were compared to 10 year test results in 45 degree South Florida
exposure for a number of other well-known coating materials. The 45 degree South Florida testing is considered
one of the best tests for ultraviolet light resistance because it tests performance in actual intense outdoor sunlight
with its full spectrum of radiation rather than artificial light.
After 4 years of South Florida exposure, the amount of film erosion of the SunGUARD UV
coating was 0.02%. Extrapolating this result to 40 years, just 0.2% film erosion would occur. While the film erosion
rate would likely increase somewhat over time, taking into consideration the chemical composition of the coatings
tested and drawing upon decades of experience by the coating manufacturer, the manufacturer projects that
erosion of the SunGUARD UV coating over 40 years of 45 degree South Florida exposure will not exceed 20% of
a one mil coating.
With the PUPI minimum dry film thickness of 1.5 mils, SunGUARD UV coatings on PUPI crossarms have a
minimum project life well beyond 60 years.

PUPI crossarm flammability testing
PUPI crossarms are self-extinguishing after removal of direct flames.
Flammability tests have been conducted on standard crossarms and also on cut specimens according to ASTM D635
horizontal burn and ASTM D3801 vertical burn tests.
Organic surface materials in the coating and the fiberglass beam surface ignite under direct flame exposure, but the arm
quickly extinguishes after the flame is removed.
PUPI arms are highly loaded with fiberglass and other inorganic materials that do not support combustion.
Flammability Tests
Beam Wall Cut Specimens
PUPI crossarm cut specimens 13mm wide were tested according to ASTM D635 and D3801 (equivalent to ANSI/UL 94)
test procedures by Element Testing, St. Paul, Minnesota:

- D635 horizontal burn: no specimen of ten reached the 25mm reference mark.

- D3801 vertical burn: passed V1 vertical burn classification.
Full Beams
We conducted more aggressive tests on standard PUPI beams:
1. Flame is applied for 30 seconds and then withdrawn, record after flame and afterglow times.
2. As soon as the flame goes out, repeat the flame exposure at the same location for 30 seconds.
3. Record after burn and afterglow times.
4. Run longer flame exposure: two minute flame application followed by 2 minutes additional flame application at
same location.
5. Then 5 and 10 minute flame applications.
6. Tests were run with gray PUPI Series 2000 crossarms, which are thin wall PUPI 3-5/8 X 4-5/8 beams.
Five specimens per test for the shorter tests, two for the longer tests.
Results:
Flames self-extinguished for all tests. There was no afterglow in any test. There was no dripping of material in
in any test.
Beams burned only in the area of direct flame application.
Burn diameter and burn depth into the beams were measured. Beam wall thickness is 0.27.
