Fused and Bonded Mini Mesh Specifications
ASTM F668, Federal Specification RR-F-191/1E Type IV, AASHTO M-181 Type IV Class B
Product Name: Fused and Adhered Poly (Vinyl
Chloride) PVC Coated Steel Chain Link Mini Mesh Fence Fabric
Basic Use: Fused and adhered PVC coated fabric
is a bonded vinyl, high strength galvanized steel chain link
fence
fabric for industrial, commercial and institutional
applications. Fused and Adhered 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: The galvanized steel
core wire for producing extruded and adhered PVC 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 galvanized coating is produced by passing the cleaned wire
through a bath of molten zinc which conforms to ASTM B6. The
fused and adhered PVC coating is produced by first applying a
thermoset bonding agent to the galvanized core wire to which the
PVC is bonded. A coating of PVC 0.006” (.15mm) - .010” (.25 mm)
is then fusion bonded to the wire.
Standards:
ASTM B6 – Slab Zinc
ASTM F567 – Installation of Chain Link Fence
ASTM F668 – Poly (Vinyl Chloride) (PVC) and Other Organic
Polymer-Coated Steel
Chain Link Fence Fabric, Class 2b
Federal Specification RR-F-191K/1E – Fencing, Wire, and Post
Metal (Chain Link Fence Fabric), Type IV
AASHTO M-181 – Chain Link Fence, Type IV, Class B
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 vinyl coating is
thermally bonded to a thermoset bonding layer over a galvanized
steel wire. This process ensures a tightly adherent and
impervious coating free of voids, as well as a smooth and
lustrous surface appearance. Vinyl coating thickness, galvanized
coating weight, and wire tensile strength conform to ASTM F668,
Class 2b. Federal Specification RR-F-191/1E Type IV, and AASHTO
M-181 Type IV, Class B. The wire is PVC coated before weaving
and is free and flexible at all joints. Unless otherwise
specified, fabric woven in 2” (50 mm) mesh, under 72” (1,830 mm)
is knuckled at both selvages; fabric 72” (1,830 mm) high and
over is knuckled at one selvage and twisted at the other. All
fabrics woven into meshes under 2” (50 mm) have both selvages
knuckled.
Wire Coating: Only plasticized poly (vinyl
chloride) (PVC) with a low temperature (-20 C ; -4 C)
plasticizer and no
extenders or extraneous matter other than the necessary
stabilizers and pigments, is used. The PVC coating resists
attack from prolonged exposure to dilute solutions, most
commonly mineral acids, seawater, and dilute solutions of most
salts and alkali. The PVC coated wire shall pass the test for
adhesion contained in ASTM F668 for Class 2b chain link
fabric.
Installation: Install fence in accordance with
ASTM Practice 567. Handle all PVC coated material with care. If
PVC
coating is damaged during installation, contractor must replace
or repair the material at his or her expense.
Maintenance: Periodic inspection is recommended
but no routine maintenance is required.
