Plank fence is an interesting alternative to post and rail fence for an acreage.
It's terrific for horse pastures, it's completely made of wood and it's appearance offers a wonderful rustic charm as seen in the photo above. This fence we built on an acreage just outside of Cochrane is constructed with pressure treated fence posts set 8 feet apart and most commonly three 2x6x16 foot rough cut planks. If additional height is required we install taller fence posts and an optional, equally spaced 4th plank.
