For over 50 years, Tri-State Lumber Co. has supplied timbers for pole barn construction. Throughout U.S. history, post-and-beam construction concepts and design have been used as the model for constructing rural buildings, previously referred to as pole barns. Post-frame buildings are known for their reliable performance and ability to withstand severe weather conditions.
We manufacture and pressure treat Southern Yellow Pine timbers from 4×4 through 12×12 up to thirty feet in length. Special orders for large dimension timbers and lengths up to forty feet are not a problem. We also stock 2×6 and 2×8 lumber for splashboards.
