Welded-wire fencing comes in roll form, not in panels or sections. Installing roll fencing on a slope is more labour-intensive than on flat ground because you have to cut each section to be installed between poles, following the ground slope, instead of fencing an entire side. This fencing technique is called stair-stepping.
Dig holes with an auger or post hole diggers to accommodate the landscape timbers for vertical fence posts at the corners. Measure the depth of each hole and make each exactly the same depth. This will automatically place the poles so they follow the slope of the ground. Prepare ready-mix concrete according to the package directions, place corner posts in holes and fill with concrete. Tie a string to the centre of each corner post for each side and line up the line post holes. Dig the line post holes the same depth and install each in the same manner as the corner posts. Let the ready -mix concrete dry for 24 hours.
Screw two-by-four or two-by-six lumber on the fence posts at the bottoms following the slope of the land. Place the rails one inch from the bottom of each post above the ground. Screw them in place with a drill using at least two screws per post. Follow the same method to install the top rails by measuring an equal distance for each from the bottom rails. Your measurements should consider that the top of the welded wire will be in the middle of both the top and bottom rails for attaching them.
Unroll a section of the welded wire and cut it with wire cutters or bolt cutters along each horizontal section next to a vertical line of the squares. Leaving the vertical line will add strength for the staples to attach it to the posts. Cut the first piece so that it will staple to the beginning edge of one corner post and the other side so that it centres on the next pole. Use a staple gun and staple the fencing to the top rail, bottom rail and onto each post with one staple tooth on each side of the vertical wire. Measure and cut the next section of welded wire so that the ends will centre on the post centres on each side of that section. Staple each section to the line poles in the same manner.
Placing poles the same distance apart from each other as the length of your lumber for rails will result in not having to cut the rails to fit and saves time when installing a welded wire fence. You may build a welded wire fence by using T-posts instead of landscaping timbers. Pound each post into the ground with the same amount of post protruding above the ground so that it follows the slope of the ground. Welded wire fences attach to T-posts with wire clips and no not require top or bottom rails. In this style of fence, you will overlap the cut sections of fences between poles and then attach through both pieces of fencing onto the T-posts with wire clips.
