You want to make sure you have the class 3 Galvanized wire, it will resist rust and weather better then just plain wire will which for the most part is what Lowes sells. If it is not a class 3 galvanized you run the risk of the corrision happening and then replacement in just a few years or a weak spot where corrision is occuring. The barbed wire is a good deterant for preditors if that is an issue but smooth wire is easier to work with and if the deer hit it, it will not tear them up. That eatra wire at the top is really to make your fence 10' tall which is a requirement in some states that your fence be 10' tall. I believe in saving money like the next guy does which is why my prices are very competitive but at the same time I dont want to have to redo work that should last many many years. Stay-Tuff has a 10 year warrenty on their fence so please make sure the fence you are investing in to keep your great deer behind will take it and last. I have received many phone calls over the years complaining about the fence that was purchased and placed on farms only to realize that the investment for the fence is just as important as the investment in the deer. Not sure where most fence is produced but Stay-Tuff is made in the USA, much of the overseas fence is thinner (weaker) and is less galvanized.
It really is time for a new idea in fencing. More strength. Much longer life. Much less costly to install. A better idea. We call that "the Stay-Tuff Advantage." It's all because the unique Stay-Tuff manufacturing method offers several advantages over conventional hinge-joint products. It's just better for the modern rancher and farmer..
To begin with, the product is manufactured from 12 1/2 gauge, Hi-Tensile, class 3 galvanized wire, offering three times the life and nearly four times the strength over most conventional low tensile wire. Hi-Tensile wire won't stretch. It has less than 1% elongation, compared to 11% elongation for low tensile wire. When you combine this with a very deep crimp, the producer can put up the fence, tighten it, and the fence will remain tight. When stock pressure, snow load, and the occasional tree falls on the fence, it will give with the load, it will not stretch, and it will spring back to its original shape.
Stay-Tuff fence is manufactured using a solid vertical stay rather than the conventional hinge-joint between vertical and horizontal wires. This provides superior vertical strength, allowing the fence to literally stand by itself, and providing much greater resistance to stock pressure preventing penetration of the fence. And last, but certainly not least, Stay-Tuff is manufactured domestically in the USA
