Poly Panel Nets Give Long Safe Economical Service
Why Polypropylene?
Years ago polypropylene was a little known name in ropes. Today it
has virtually ”taken over” in many areas.
On the waterfront from steamship hawsers and deck ropes to tug and
barge tow lines the swing has been from manila and nylon to polypropylene.
o APPROVED SAFETY NET SPECIFICATIONS
With the oil companies in drilling and maintenance operations from
Alaska to the Caribbean and world wide, polypropylene is the rope most
used.
o LEASE OR PURCHASE
With the power and light companies installation and maintenance work
uses polypropylene. Having excellent insulation properties, it is used
in power line stringing and related uses.
o PROMPT DELIVERY
There are good reasons for this swing:
o ECONOMICAL
The abrasion resistance of polypropylene is very good, its elasticity
is moderate and the recovery excellent.
o LONG USEFUL LIFE
o SHOCK ABSORBING
Resistance to sunlight and weather deterioration is a strong quality.
Polypropylene 3/8” black rope exposed under Florida sunshine test for 7
months lost 1% of its tensile strength. Under a Fade-0-Meter test the loss
was 2% in 7 months.
o LIGHTWEIGHT
Polypropylene absorbs no water and is completely resistant to rot and
mildew.
o MADE TO ORDER OR STANDARD SIZES IN STOCK
Approved Standard Polypropylene Safety Nets
Dependability and long useful life. These are the qualities that
have been combined by Canadian Automotive Ltd. to produce Safety Nets.
For more than twenty years these safety nets have been produced with a
proven record of safe, economical service.
Poly Panel Safety Nets feature unexcelled life expectancy in both permanent
installations and intermittent use. When permanently hung and exposed to
severe weather, Poly Panel nets have given six to eight years of continuous
service. When employed intermittently on heavy construction and tested
before each new job, Poly Panel nets that were produced ten and twelve
years ago are still in use today.
Poly Panel Safety Nets made to the following specifications fully meet
all safety requirements of Federal and State agencies including OSHA and
American National Standards.
Mesh Rope 5/16” Dia. Black Polypropylene Rope weighing not less than
1.90 lbs. per 100 feet and with minimum breaking strength of 2000 lbs.
Edge Rope 5/8” Dia. Black Polypropylene Rope with minimum breaking
strength of 5800 Ibs.
Mesh 6” x 6” measured from center to center of mesh rope.
POLY PANEL NET CONSTRUCTION
Diagonal mesh pattern with mesh members meeting the edge ropes
at 45 angles.
The safety record of Poly Panel Safety Nets is just as impressive.
Falls into Poly Panel nets have occurred on scores of occasions - falls
up to 75 feet. The record speaks for itself; Poly Panel Safety Nets have
assured a safe landing on all occasions.
All mesh crossings and attachment of edge rope to mesh positively secured
with patented fiberglass and plastic bindings which prevent movement and
eliminate chafing and frictional wear. The full strength of the rope is
preserved since there are no weakening knots or disturbance of the ”lay”
of the rope.
Stainless Steel double thimbles connect panels of mesh forming a net.
This patented construction provides additional flexibility and shock absorbing
quality.
Weight of these nets is approximately one fifth of a pound per square
foot.
Tested and Approved
Test Specifications
Poly Panel Safety Nets are made to specifications that have been
thoroughly tested and approved for personnel safety net use by Federal
and State agencies. including the Army Corps of Engineers, the U.S. Bureau
of Reclamation, OSHA and American National Standards
.Testing Procedure
Testing of prototype nets under carefully prescribed conditions
is a requirement for safety net qualification. Testing consists of dropping
a 350 pound test weight of not more than 4 cubic feet from a distance of
50 feet into a net 17 by 24 feet in size, This test produces a force of
17,500 foot pounds. Poly Panel Safety Nets have successfully withstood
up to 31,500 foot pounds under the conditions prescribed above and as much
as 50,000 foot pounds repeatedly under similar conditions with larger nets.
It is this
extra reserve of strength thatresults in the safety and extended life
span that are the hallmark of Poly Panel Safety Nets.
How Poly Panel Nets Are Made
Poly Panel Net construction combines great flexibility and elasticity
with maintenance of the maximum strength of the rope used.
Lashings of ”Fiberglass” reinforced polyester resin secure ail ”mesh”
ropes in mesh position. The edge or ”ridge” ropes are similarly secured
to the mesh.
Using this ”tie” there is no distortion or displacement of the ”lay”
of the rope, its full strength is unimpaired. Penetration of the crevices
of the rope ”lay” by the plastic at the ”tie point” creates a firm positive
attachment, with no slip or resultant friction and wear. ”Fatique is not
a factor in these materials which will long outlive the rope itself.
”Panels” of mesh are made in varying dimensions to fit desired net
measurements. In small nets a single panel may be used, but in larger standard
size nets a succession of panels are secured together, using ”double thimbles”
of stainless steel over which the mesh rope can slide, ”spreading” stresses
of shock and adding to flexibility.
The above photo shows one of the tests which was performed on the net
test facility. This test demonstration was attended by more than forty
qualified representatives of industry, construction, government and safety
associations in North America. All the nets passed the tests.
Built in accordance with the requirements of the American National
Standards Institute for safety net testing, this frame is available for
use on request.
A VHS video, some of which was taken during the test and which was
produced by the Construction Safety Association of Ontario, entitled The
Net Result is Survival is also available for your viewing. Please send

SAVING MONEY WITH SAFETY NETS
Safety Nets saved time and money on this multi-story job replacing
”Boarding Over” for a fraction of the cost and with greater safety.
This is a 12-story building All stuctural steel will be quickly placed
by a mobile crane operating at ground level The decking, however, will
go in more slowly, and could delay steel erection. OSHA regulations call
for worker-protection against, falls
within two stories of the working level The Contractor has three choices.”board-over”,
”tic-off” or use safety nets. If he is smart, he’ll provide greater safety
for his workers -- and save money doing it --- by using safety net. Ask
us and we’ll show you how!
Nets For Lease
Our Poly Panel Safety Nets are available for prompt. shipment on a
lease basis. For those contractors having only occasional need for safety
nets, leasing is often advantageous. All leases carry a purchase option.
