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.
