One type of coated wire fencing is wire mesh coated in vinyl materials, such as polyester or PVC. The vinyl is welded or weaved into the wire mesh and protects against rust and corrosion. Zinc, aluminum, polymers and polyethylene are other common materials used for coating wire fencing.
Zinc and aluminum coated wire fencing are cheaper than vinyl coated fencing, but typically protect against the elements better and last longer as vinyl tends to peel. Aluminum coated fencing also has greater tensile strength than zinc or vinyl coated wire fencing.
One example of coated wire fencing used for horses is the High Impact Raceline Coated Wire. It consists of 12.5-gauge, high tensile wire double-coated in a mildew resistant polymer material. Another example is the ShockLine Electric Coated Wire, which is high tensile steel wire with polyethylene coating, and conductive, carbon strips to provide the electric shock without causing injury to the horses it is meant to contain.
