This is one of the toughest deer fences available on the market today. Our 12.5 gauge solid fencing is class 3 galvanized, which is the highest galvanization rating available, making it extremely resistant to corrosion. We also have a 14 gauge fixed knot fencing. Our 14 gauge fencing features an advanced zinc aluminum coating and is nearly 2-3 times as corrosion resistant as class 1 galvanized steel. Fixed knot fencing will stop the most determined buck and has an estimated life of 20-40 years.
