What is Chain Link Fabric?
Fabric comes in a
variety of gauges. Gauge is the diameter
of the wire; the higher the gauge number
the smaller the wire diameter. Standard
mill diameter tolerance is + or - .005.
Common gauges and diameters are as
follows:
- 6 gauge=.192
- 9 gauge=.148
- 11
gauge=.120
- 11 ½
gauge=.113
- 12
gauge=.106
- 12 ½
gauge=.099
Chain link fabric
is available in heights of 36, 42,
48, 60, 72, 84, 96, 120, and 144.
The fabric is formed by weaving a series
of spirals together. How the top and
bottom of fence is finished is referred
to as the selvage. Fences less than 72"
must knuckle both ends by industry
standard (KK). Heights of 72 and
higher, are generally twisted or barbed
at one end and knuckled (BK) on the
other. For high security enclosures,
chain link can be obtained with both
ends twisted or barbed (BB).
Zinc coatings may
also differ. There are two different
processes for applying zinc to wire.
Galvanized after weaving (G.A.W.) is a
process in which wire rod is drawn to
the finished gauge, then woven into
chain link fabric. The fabric is then
pulled through a pot of molten zinc,
which applies 1.2 ozs. of zinc coating
per square foot of fabric and conforms
to ASTM standards.
The other process
for applying zinc coating to chain link
is called galvanized before weaving (G.B.W.).
In this process the wire rod is drawn to
gauge, and the strand wire is then
pulled through a pot of molten zinc. The
wire is then woven into chain link
fabric. Generally chain link fabric made
using this process carries a zinc weight
of .8 ounces per square foot or less.
The distance
between two parallel wires in the fabric
is referred to as the mesh size. The
most common mesh sizes are 2 or 2 Ό,
but smaller meshes of 3/8, 5/8, 1, 1
Ό, 1 ½ and 1 Ύ are available for
projects that require a higher degree of
security.
The quality of
chain link fence fabric is determined by
both the gauge of the wire and the
weight of the zinc coating applied to
the wire. The American Society for
testing material has established
standards for residential and commercial
chain link fence fabric under
designation A 392-96. |

What is Frame Work?
Frame work is the
tubular steel frame that chain link
fabric is attached to. The frame work is
comprised of three components; top rail,
line posts, and terminal posts. Terminal
posts are set in concrete and are end,
corner, and gate posts. Line posts are
smaller in diameter than terminal posts
and are the intermediate posts between
terminal posts. These should also be set
in concrete. The top rail is attached to
the terminal posts and passes through
fittings which are attached to line
posts. This provides a horizontal frame
that supports that fabric.
The chain link
fence frame work is also zinc coated to
provide protection against corrosion.
There are two methods of coating tubular
products. In the first method, coils of
steel are slit to the proper width, then
formed into pipe and the seam is welded.
After the pipe is formed, the pipe is
then taken to a pot of molten zinc and
submersed. Both the interior and
exterior of the pipe are zinc coated.
This method is referred to as the hot
dip process.
In the second
method, the width coil of steel is
formed into pipe and then seam welded.
It then passes through an in line vat of
molten zinc, which coats the exterior
with zinc. A clear organic coating is
applied over the zinc, providing
additional protection from corrosion.
The interior of the tubing is coated
with a zinc rich paint. This method is
referred to as in line, flow coat
galvanizing.
Both methods of
manufacturing conform to ASTM F669-92.
The quality of tubular products is
relative to the thickness of steel, as
well as the zinc coating. Please refer
to chart one for further information on
tubular products and typical
applications.

What are fittings
and how are they used?
To assemble a chain
link fence systems several types of
fittings are required. Fittings can be
classified into three types; those used
in the line of fence, those used on
terminal posts, and those used in
conjunction with gates. All residential
fittings are made from a die cast
aluminum or steel that has been
galvanized. Industrial and commercial
fittings are made from galvanized steel,
cast iron, or malleable steel. Fittings
are an integral part of the fence, as
they secure the components of the fence
system. Gate fittings are especially
important. The gate is the only part of
the fence that moves and that people
come into contact with on a regular
basis. It is very important that they
fit and do not move on the gate post
once installed. This will keep the gate
from sagging. For security, barbed wire
can be added to all types of commercial
projects. Fittings should conform to
ASTM F 626-96. |

What types of
residential gates are available?
For residential
applications two types of gates are
commonly used; single walk and double
drive. Single walk gates are generally
used for people to pass through,
although they can be made up to 12 wide
and are always the same height as the
fence. It is a single panel that is
hinged from one terminal post and
latched to another. Double drive gates
consist of two panels that latch in the
middle of the opening. Both single walk
and double drive gates for residential
enclosures are made from 1 3/8 diameter
tubing. Bent frames with rounded
corners, aluminum ell corners, and
square welded corners are also
available. The quality of the chain link
and frame work used should match the
rest of the fence. Automatic closing
mechanisms are available to shut and
latch the single walk gate after
passage. |

Are there
different types of gates for commercial
projects?
In addition to single
walk and double drive gates, several
types of sliding gates are available for
commercial and high security
applications. Sliding gates are used
where there is no room to swing the
panel of a single or double gate. In
areas where snow and ice are not a
problem rolling gates are not
recommended. Rolling gates roll on a
pipe track that is attached by track
brackets to the gate post and line posts
and is on a ground carrier that is
attached to the front of the gate.
Sliding gates are made from 1 5/8 or 1
7/8 diameter frame work. For security,
barbed wire or barbed tape can be added
to all types of gates.
Commercial single
and double drive gates are usually
welded, or made with gate ells.
A cantilever gate
is 1.5 times the length of the gate
opening and is suspended by four
malleable rollers, which are attached to
two posts. Rollers are attached to the
gate and first line post, one at the top
and one at the bottom of each post; this
allows the gate frame to slide between
the rollers. Cantilever gates are very
heavy and are usually installed on 4
diameter posts and constructed from a
2-3/8 diameter top and bottom rail.
We also handle a
complete line of residential and
commercial gate operators that can be
used with any of the gates mentioned.

Are chain link
fence systems available in Colors?
A1A Fence
offers two different types of color
systems. First, we have a product line
that is the perfect choice for property
owners who need a fence that delivers
the strength of chain-link, but desire a
fence that blends beautifully with the
environment. No other fence
provides as much security, lasts as
long, or safeguards the beauty of your
home and its surroundings quite. This
product is available in a standard
variety of colors.
A1A Fence
offers a chain-link fabric with a
tough polyvinyl over a galvanized steel
core wire. We produce wire that has a
very high P.S.I. breaking strength,
which is then coated with polyvinyl.
Our framework is
our galvanized framework that has a
polyester powder coating on it, giving
double protection from the elements and
corrosion. The framework is prepared for
coating by going through a multi stage
chemical conversion process. It is then
electrostatically powder coated and
thermally bonded to provide a superior
color coating.
Commercial
applications, with an interest in
beauty, provides the protection,
security, and durability that is
expected from quality chain link fences,
but adds good looks. No other fence
combines utility with aesthetic luxury.
Available in forest green, olive green,
midnight black, sierra brown, and tan.
Commercial fencing combines a tough
polyolefin coating over galvanized
steel, which results in a fence that
will withstand harsh elements, as well
as provide maximum security and
protection. |

Are
A1A Fence
products warranted?
Some of our
galvanized systems are warranted for 12
years. The best thing about our
warranties is that they warrant the
protective coatings. Many manufacturers
offer warranties that apply only to the
loss of structural integrity of the
steel, meaning the product has rusted to
the point that the strength of the steel
is no longer there. Most warranties
apply if the protective coatings fail,
which will occur much sooner than loss
of steel integrity. |
