Zareba® 1000-Foot 12 1/2 Gauge Aluminized Steel Wire

Zareba® aluminized steel wire is a permanent electric fence line designed especially for high tensile fencing. Installing multiple wires on your fence posts serves as a physical barrier and as a psychological deterrent for your livestock and horses. This 1,000-foot aluminized steel 12 ½ (12.5) gauge wire is mounted on a spool for easy de-reeling. Durable and reliable, the wire features a 1,500 lb breaking load and 200,000 PSI tensile strength. Your Zareba® rust-proof wire can be mounted on porcelain or plastic insulators.



This Zareba® fence wire is highly durable and serves as an excellent line for livestock containment.  It features a 1,500 lb breaking load and a strength of 200,000 PSI. The wire’s rust-proof aluminum coating will outlast zinc-coated wire in highly corrosive conditions while also providing superior electric conductivity.



Your aluminized steel wire can be mounted on all fence post types by using porcelain or plastic insulators. During installation, always handle coiled wire with extreme caution. Wear the appropriate safety gear, including gloves and safety glasses.



To help you install your aluminized steel wire, use a Zareba® Spinning Jenny Electric Fence Wire De-Reeler to quickly run your line. Once installed on your insulators, use an 8-Light Electric Fence Voltage Tester to gauge your fence’s power levels. Picking the right energizer is also important to properly contain your livestock – most high-tensile fences use an AC-Powered Fence Charger.

excellent wire. By Jody

HT fence is the ONLY way to go. Too many years of having barbed and woven wire fences just aren't making the cut when it comes to keeping livestock where they are supposed to be. Build good HT fences, get a good charger, and forget about fences.

Expert Tips


The height and spacing of the wires will vary with the animal you are containing. Position one electrified wire at animal’s shoulder height; this will cause it to hit the fence with its nose, making it back up.


Use poly tape for horse fencing or in rotational grazing since the animals can easily see this highly visible electric fence wire. Splice poly tape with splicer buckles specially designed for easy splicing and repairing of poly tape.


Poly wire is lightweight, so it is very easy to handle. You can rewind it very easily, move it and re-use it. Splice poly wire by tying a good, tight knot to maintain connections. Use a poly wire line tightener on each line and each side of the fence to maintain wire tension.


Also highly visible, this electric poly rope is also used for horses and livestock. When repairing poly rope, use a splicer designed for poly rope to maintain a good electrical connection.


Use a low impedance fence charger with poly wire and poly tape products.


For a permanent perimeter fence, you may want to use high tensile or steel wire as your fence wire.

Fence Wire FAQs

Q: Why is poly tape better for use with horses than regular wire?

A: It's a matter of visibility. Horses can see the tape more readily than wire. Remember, electric fencing is a psychological barrier: after a horse has met up with a poly tape electric fence and has felt the shock, when it sees the poly tape again, it will remember the shock and stay away from the fence.


Q: Why should I place one wire at the animal's shoulder?

A: Positioning one electrified wire at animal’s shoulder height will cause the animal to hit the fence with its nose, making the animal back up. See illustration below.


Q: What is the advantage of using high-tensile wire rather than aluminum wire?

A: High tensile wire is designed to be both a psychological barrier and a physical barrier. High tensile wire not only carries a shock, it is also sturdy enough to prevent a large bull from penetrating the fence line (as long as it has been installed correctly.)

In addition, aluminum wire can stretch out over time as tension is applied to it (very slowly). High tensile wire will not stretch; this affordable barrier can last for many, many years.
