Wire fence is a versatile and cost-effective solution for defining property lines, securing livestock, and providing general perimeter protection. It is typically made from galvanized steel wire to resist rust and corrosion, ensuring a long lifespan even in harsh weather conditions. The most common configuration is the "woven wire" or "field fence," where vertical and horizontal wires are interlocked at every intersection. This creates a rigid grid that can withstand significant pressure from animals leaning against it or debris hitting it. The mesh size can be customized based on the intended use—smaller apertures for keeping out pests like rabbits, and larger ones for containing cattle or deer.
The structural integrity of a wire fence relies heavily on the tension of the wire and the strength of the posts. Because wire has a natural tendency to sag over time, it must be stretched tightly between sturdy posts, usually made of wood, steel, or concrete. In areas with high wind loads, the posts need to be set deeper into the ground and possibly braced with concrete. For agricultural applications, the bottom of the fence often features a "stay" or a heavier gauge wire that stays close to the ground to prevent animals from pushing under. The top rail provides additional rigidity and prevents the fence from twisting.
Installation of wire fence is a labor-intensive process that requires specific tools like wire stretchers and come-alongs. The fence is unrolled along the property line, and the wire is pulled tight before being stapled or nailed to the posts. Care must be taken not to over-tighten the wire, as this can cause it to snap or pull the posts out of alignment. In rocky or uneven terrain, the installation may require clearing a path or using specialized post drivers. For security applications, the top of the wire fence might be finished with barbed wire or razor mesh to deter climbing, transforming a simple boundary into a formidable barrier.
Maintenance for wire fence is relatively low compared to solid barriers, but it is essential for longevity. The primary task is checking the tension; a loose fence is ineffective and can be easily breached. Broken wires should be spliced immediately using crimp sleeves or wire clips to restore the fence's integrity. Vegetation growing through the mesh should be cut back to prevent it from adding weight or hiding gaps. While galvanized wire resists rust, any scratches in the coating should be touched up with a zinc-rich paint to prevent corrosion from setting in. A well-maintained wire fence can last for decades, making it one of the most practical choices for large-scale enclosures.
