How to Choose Pole Barn Columns: Laminated vs. Solid 

The treatment of our columns exclusively involves the use of southern yellow pine. The approach to treating these columns may vary depending on the builder and their specific practices. Typically, builders either treat the columns entirely or not at all, with little middle ground.

most common is treated below ground then soft whitewood above..BE SURE YOU WATCH CLOSELY! LOWES WILL SELL YOU "" NOT GROUND CONTACT LUMBER even though it says treated!!WATCH the tags!

actaully ready-made factory laminated poles are always treated below and un treated above @@FBiBuildings1958

Thank you for sharing your experience. It's unfortunate to hear about the twisting of your solid columns. Twisting can occur due to the natural drying and shrinking of the wood, especially if it's not properly dried before installation. This is one of the reasons why many builders prefer laminated columns, as they are engineered to reduce the risk of twisting and warping over time. If you're looking to get these columns replaced, please feel free to reach out to us. We'd be happy to help if you're in our service area. www.fbibuildings.com/about-us/our-service-area/

The number of plies in a truss can vary. Single-ply trusses commonly have three plies, while double-ply trusses typically have four. Additional plies can be added as required.
