Wire fences are generally the most inexpensive type of farm fence to install, especially compared to lumber. Barbed wire is one of the cheapest options due to its simple materials, making it a good choice for low budgets and for confining docile animals in large spaces. Other options include hog wire and woven wire fences, which are strong, long-lasting, and relatively easy to repair. While wire fences require less lumber and reduce overall project costs, they are often considered less aesthetically pleasing than traditional wood fences.

If you’re looking for a budget-friendly fence material, corrugated metal could be the answer. Metal fences cost about $7 to $32 per foot. Aluminum corrugated metal tends to be less expensive than steel. Both options are similar in cost to wood, so, depending on the type of wood you are considering, corrugated metal could be better for your budget.

When your rolls of silt fence join together, you’ll want to overlap them to make sure they’re still as effective at keeping water out without requiring fastening together. Overlap two sections of the silt fencing so that two sheets of fabric cover the span of two posts. If you want to fasten them together, you can staple them or use a zip tie, depending on whether your posts are metal or wood. 

The most durable metal for a fence is wrought iron. With proper care, a wrought iron fence can last for centuries. This means regular resealing to stave off rust and corrosion, especially in coastal climates with salty sea air. In these environments, chain link and corrugated fencing tend to stand up better to the elements with fewer maintenance needs.
