Galvanized Mini Mesh Specifications
ASTM A392, Federal Specification RR-F191/1F Type 1, AASHTO M-181 Type 1
Product Name: Zinc Coated (Galvanized) Steel
Chain Link Mini Mesh Fence Fabric
Basic Uses: Zinc coated (galvanized) steel
chain link mini mesh fence fabric is best for industrial,
commercial and institutional applications. Zinc coated fabric is
contained in local, state and federal government specifications
for use in prison, road, dock, airport, housing, forestry, and
military use.
Composition and Material: Zinc coated steel
chain link fence fabric is produced by cold drawing good
commercial grade steel rod into wire of the appropriate
diameter. The steel rod from which the wire is drawn is produced
by the open hearth, electric furnace or basic oxygen process.
The zinc coating may be applied before weaving into fabric (GBW)
or after weaving into fabric (GAW). Galvanized before weaving
(GBW) – The wire is cleaned, passed through a bath of molten
zinc, and then woven into chain link fabric. Galvanized after
weaving (GAW) - The uncoated wire is woven into chain link fence
fabric of the appropriate height and mesh size. The coating is
produced by passing the woven mesh through a continuous line
which includes cleaning of the fabric. After cleaning, the
fabric passes through a molten bath of zinc metal to produce the
galvanized coating. Zinc used to produce the coating conforms to
the requirements of ASTM specification B6.

Technical Data
General: The manufacturer, if requested, will
supply samples and certification that all materials furnished
comply with the appropriate specifications.
Chain Link Fence Fabric: The base metal of the
chain link fence fabric is composed of commercial quality,
medium carbon wire. The weight of the zinc coating, wire sizes
with allowable variances, and wire breaking strength, conform to
ASTM A 817 for the wire size specified. The fabric is zinc
coated either before or after weaving.
Coating Weight: Zinc coated (galvanized) steel
chain link fence fabric conforming to ASTM A 392 and other
specifications referenced above is available in two coating
classes with the following minimum weights :
Class1 – 1.2 oz/sq ft (366 g/ sq meter)
Class 2 – 2.0 oz/sq ft (610g/ sq meter)
GAW is available in either class. GBW is limited to Class 1 due
to the limited availability of galvanized wire with a
Class 2 coating. Fabric woven with mesh size less than 1” is
only available in GBW.
Sizes: Galvanized fabric is available in mesh
sizes from 3/8” to 2 3/8”, and in heights from 18” to 240”.
Unless
otherwise specified, chain link fence fabric woven with a 2”
mesh and 60” or less in height is knuckled at both
selvages. For fabrics 72” and taller, the selvage is knuckled at
one edge and twisted at the other. All fabrics woven
into mesh sizes under 2” are knuckled at both selvages.
Installation: Install fence in accordance with
ASTM Practice 567.
Maintenance: Periodic inspection is
recommended, but no routine maintenance is required.
