7 or 9 gauge PVC Coated Tension Wire for Chain Link Fence
PVC and other conforming organic polymer-coated steel tension wire used with chain link fence.
Three classes of tension wire coating:
- Class 1, consisting of a polymer coating extruded over zinc-coated or aluminum-coated or zinc-5% aluminum mischmetal alloy-coated steel wire;
- Class 2a, consisting of a polymer coating extruded and adhered to zinc-coated or aluminum-coated or zinc-5% aluminum-mischmetal alloy-coated steel wire; and
- Class 2b, consisting of a polymer coating fused and adhered to zinc-coated or aluminum-coated or zinc-5% aluminum-mischmetal alloy-coated steel wire.
