Features

• Built to Last 30+ Years: Invest with confidence. Our heavy-duty Class 3 Galvanized coating provides 3X the rust protection of standard Class 1 farm store wire, ensuring decades of reliable service in the harshest weather.
• Unyielding High-Tensile Strength (CARBON STEEL): With a breaking load of over 1,500 lbs, this high-carbon steel wire will not sag under heavy grape loads or break from livestock impact. It allows for wider post spacing, saving you material and labor costs.
• The Professional's Choice for Vineyards & Ranches: The ideal foundation for both vineyard trellis systems and high-impact permanent livestock fencing. The smooth wire design is safe for animals and won't damage valuable hides.
• Easy, Kink-Free Payout: Engineered to be torsion-free, our wire pulls straight from the coil without twisting or kinking, saving you hours of frustration during installation.

Installation Best Practices

A successful, long-lasting system depends on proper installation.

1. Build Strong Corners: The strength of your system is in its anchors. Always use a properly constructed H-brace for all corner and end posts to handle the immense tension.
2. Use a Spinning Jenny: Never uncoil high-tensile wire by hand. A spinning jenny ensures a safe, smooth, and tangle-free payout, preventing dangerous and wasteful kinks.
3. Never Kink the Wire: A sharp bend creates a permanent weak point. If a kink occurs, it must be cut out and spliced with a connector.
4. Use Modern Connectors: For splices and tensioning, we strongly recommend using modern mechanical connectors and their corresponding tensioning tools. This method provides a fast, reliable, and professional result.

Primary Applications

• Commercial Trellis Systems: The perfect vineyard trellis wire for supporting heavy crop loads in vineyards, orchards, and hop farms. The high-tensile strength prevents sag, ensuring optimal canopy management.
• High-Tensile Livestock Fencing: An ideal 12.5 gauge wire fence for containing high-impact livestock like cattle and bison. Also used for excluding deer and other wildlife. Often used in electrified systems.

FAQ

Does galvanized wire rust?

All galvanized wire will eventually rust, but the lifespan depends entirely on the thickness of the zinc coating. Our Class 3 wire has nearly three times more protective zinc than common Class 1 wire, giving it a 30+ year lifespan compared to the 2-12 year lifespan of standard wire.

What is galvanized wire?

Galvanized wire is a steel wire that has been coated with a protective layer of zinc to prevent rust and corrosion. The zinc acts as a "sacrificial" barrier, corroding first to protect the steel core, which dramatically extends the wire's functional life.

What is vineyard wire?

Vineyard wire is a high-tensile, small-diameter steel wire used to create the trellis systems that support grapevines. It must be incredibly strong to hold the weight of mature vines and their fruit, and highly corrosion-resistant to last for the multi-decade life of the vineyard.

What other names does this product go by?

This product is also commonly called trellis wire, high-tensile fence wire, or 12.5 gauge galvanized wire.
