Welded wire fencing features steel wire welded together to form a grid of square or rectangular openings that range in size from 1 1/2 inches to 9 inches. The wire is electro-galvanised, hot-dip galvanised or plastic coated to protect the wire from weather-induced rust. The fencing comes in 25-, 50- or 100-foot rolls and in a variety of gauges. Considered a low-cost and low-labour fencing option, welded wire fencing provides a physical barrier for domestic animals, wildlife and children.
Use a tape measure to determine how tall the fence should be. Rolls of welded wire fencing are available in heights of 36 to 72 inches. The fence posts should be approximately 2 feet taller than the fencing. For example, a 36-inch fence requires 5-foot fence posts.
Hammer a wooden stake at each corner of the proposed fenced area. Measure to determine how much wire fence and how many posts are required to complete the job. To determine the number of interior posts per side and accurate placement, divide the length of the side by the distance between posts and subtract 1. For example, two corner posts 50 feet apart require four interior posts set at 10 feet apart. Two corner posts at 56 feet apart require seven interior posts set at 7 feet apart. Add the number of interior posts to the number of corner posts to determine how many total posts are necessary.
Replace each wooden stake with a corner post, installed according to the type of post. Drive metal T-posts into the ground using a post driver. Set steel pipe or wooden posts in holes and surround with concrete. Generally, corner posts should be sunk in the ground with concrete to ensure they're stable. A T-post is likely to bend from the force of the stretched welded wire.
Tie string line from corner post to corner post to provide a straight guide for the placement of interior posts. By tying it as close to the top of the posts as possible, you can use the string to gauge how high to set your interior posts, ensuring they all rise to approximately the same height.
Use the tape measure to identify where to place each interior post. Install according to type. You may combine post types, using wooden posts at corners for strength and T-posts for the interior posts to save money.
Lay the roll of welded wire on the ground with the loose end on the ground at the first corner post. Welded wire is often difficult to unroll. Rolling it out on the ground is easier than trying to manoeuvre the heavy roll in an upright position.
Cut the fencing with heavy wire cutters or bolt cutters into manageable sections according to the length of the fence and how much you can lift at a time. Two people may be able to set a 50-foot section of fencing upright but will struggle to set 100 feet upright at a time.
Install the welded wire fencing to the corner post using the appropriate method. Galvanised slice-cut staples work well with wooden posts. Tie the fence to metal t-posts or pipe fencing using sections of baling wire. Place a staple or tie at each horizontal wire.
Work down the fence line, tying the fence to each post. Depending on the size of the welded wire grid, the gauge of the wire and the fencing purpose, it may be necessary to place a tie at each horizontal wire on the interior posts.
Start a new section of fencing by overlapping the edges at a post and tying at each horizontal wire. Snip excess wire so that there are no sharp edges to endanger animals or people. Splicing creates a cleaner corner than trying to bend or wrap the fencing at the corner post.
Welded wire doesn't stretch like mesh wire fencing. Simply pull it enough to ensure that it is taut between posts.
Always wear gloves, long sleeves, long trousers and eye protection when working with wire fencing. Cut edges are sharp and unpredictable. Use caution when snipping small pieces of wire, as they may fly in any direction.
