Tri-State Lumber Co. has a full line of wood fencing products. Our Southern Yellow Pine fencing is treated for years of services. Our posts are very straight and have a more finished appearance. We also offer posts “faced” or, flat on one side for easy nailing of our wood fence boards. We also offer several species of fence boards in treated and untreated. Southern yellow pine is a popular choice because it is strong and inexpensive. By going through the pressure treatment process, pine increases its resistance to decay and insects.
