2.5mm High Tensile Fencing Wire 25kg Long-Life Zinc Aluminium

2.5mm Premium High Tensile Zn-Al Fencing Wire – 230g/m² Long-Life Coating

Upgrade your fencing with long-life performance wire. Whether you're fencing coastal farmland, hill country, or a lifestyle block, this high tensile zinc aluminium wire is engineered to outlast standard galvanised wire, saving you time, money, and the cost of re-fencing earlier than anticipated. Buy direct from the importer and save.

Why Choose This Wire

Unlike standard galvanised wire which relies on zinc alone, our 90/10 zinc aluminium alloy coating bonds more tightly to the steel and is self-healing — meaning cut ends and nicks during installation stay protected rather than becoming corrosion points. With a coating weight of 230 g/m² exceeding the AS/NZS 4534 minimum of 200 g/m², and a tensile strength of 1,100 –1,300 N/mm² that comfortably exceeds NZS 3471:1974 requirements, this wire beats the benchmark rather than just meeting it giving you genuine performance headroom under stock pressure, wind load, and ground movement. Suitable for sheep, beef, dairy, deer, horse, and lifestyle block fencing, and compatible with electric fence systems and all standard fencing tools including strainers, wire joiners, and staples, each 25kg coil delivers approximately 650 metres of wire for fewer joins and faster installation. In moderate to coastal New Zealand environments you can expect a service life of 20 to 50 years a significant step up from traditional galvanised wire.

⚡ Why 10% Aluminium Matters

Not all Zinc-Aluminium wire is the same.

Many wires on the market use lower Aluminium content (around 5%). Our wire uses a 90% Zinc / 10% Aluminium coating, providing improved long-term protection.

The advantage:

• Greater resistance to corrosion, reduced risk of early rusting
• Better performance in salt air and wet conditions

This means a longer-lasting fence and fewer replacements.

🌊 Built for New Zealand Conditions

From coastal properties to high rainfall farmland, NZ fencing is exposed to tough environments.
