Barbed wire is often used in nearly all rural fencing applications, including:
- Rural Paddocks and Fields
- Boundary & Goat Fence
- Cattle Fence
- Cattle, Sheep & Lamb Fence
- Pig & Boundary Fence
- Sheep & Lamb Fence
- Sheep Fence
Waratah® Longlife® High Tensile Barbed Wire
High Tensile Longlife barbed wires have a reverse twist pattern that delivers maximum strength against breakage and with 90mm barb spacings they provide greater pressure resistance than conventional 100mm spacings.
Longlife coated barbed wires are the only barbed wires protected with the dual coating of Zalcote® and Permaseal®. Zalcote has been shown to deliver more than double the life of conventional galvanised coatings and the Permaseal further enhances the life of the coating. Together, they can greatly extend the life of a barbed wire fence.
Additional Info
- Breaking Strain: 675lb / 3kN (for 1.57mm), 900lb / 4kN (for 1.80mm)
- Diameter: 1.57mm, 1.80mm
- Length: 500m (Reel Length)
- Recommended Tension: 300lb / 1.3kN
- Surface Finish: LonglifeT
Waratah® Iowa Barbed Wire - Standard Galvanised
Waratah Iowa standard galvanised barbed wires are widely used in less harsh environments, because they do not carry the dual protective coatings of Waratah LonglifeT barbed wires.
Additional Info
- Breaking Strain: 675lb / 3kN
- Diameter: 2.5mm
- Length: 400m (Reel Length)
- Recommended Tension: 300lb / 1.3kN
- Surface Finish: Standard galvanised
Waratah® Longlife® Iowa Barbed Wire
Longlife Iowa patterned barbed wire is produced from 2.50mm soft wire, which has greater fire resistance than high tensile wires. The barbs are spaced at 100mm intervals.
Longlife coated barbed wires are the only barbed wires protected with the dual coating of Zalcote® and Permaseal®. Zalcote has been shown to deliver more than double the life of conventional galvanised coatings and the Permaseal further enhances the life of the coating. Together, they can greatly extend the life of a barbed wire fence.

- Breaking Strain: 675lb / 3kN
- Diameter: 2.5mm
- Length: 400m (Reel Length)
- Recommended Tension: 300lb / 1.3kN
- Surface Finish: LonglifeT

- Adding barbed wire to any fence will discourage stock from pushing at the fence - e.g. above to increase the height and discourage leaning; at the foot to prevent rooting and lifting.
- The practice of running barbed wire through holes in timber posts is not recommended. A more satisfactory fence is achieved by stapling the wire to the posts after straining. This eliminates need for drilling holes and the risk of over tensioning from pulling barb through holes.
- Strains not exceeding 500 metres are recommended, as longer strains become difficult to handle.

About Barbed Wire
 Barbed fencing wire is constructed with sharp edges or points arranged at intervals along the strands. It is used to construct inexpensive fences and also on walls surrounding secured property. A person or animal trying to pass through or over barbed wire will suffer discomfort and possibly injury. A minimal barbed wire fence requires only fenceposts, wire and fixing devices such as staples.
Barbed wire for agricultural fencing is typically available in two varieties—"soft" or mild-steel wire and "high tensile". Both types are galvanised for long life. High-tensile wire is made with thinner but higher-strength steel. Its greater strength make fences longer-lasting because cattle cannot stretch and loosen it. It copes with the expansions and contractions caused by heat and animal pressure by stretching and relaxing within wider elastic limits. It also supports longer spans, but because of its "springy" nature it is hard to handle and somewhat dangerous for inexperienced fencers. Soft wire is much easier to work but is less durable and only suitable for short spans.
There are several ways to anchor the wire to a corner post:
- Hand-knotting . The wire is wrapped around the corner post and knotted by hand.
- Crimp sleeves . The wire is wrapped around the corner post and bound to the incoming wire using metal sleeves.
- Wire vise . The wire is passed through a hole drilled into the corner post and is anchored on the far side.
- Wire wrap . The wire is wrapped around the corner post and wrapped onto a special, gritted helical wire which also wraps around the incoming wire; friction holds it in place.
- Gripple . The wire is wrapped around the corner post and gripped by a vise which also attaches to the incoming wire.
