Pole Barn Posts & Column Options
The foundation of your building starts below ground. Compare glued laminated columns, solid 6x6 timbers, and rot-free precast concrete perma-columns.
Heavy Preservative Retention
Ground-contact posts are treated to .60 PCF CCA retention for extreme resistance against fungal decay, termites, and soil moisture.
Deep Concrete Footings
Posts are set on engineered concrete pad footings below Ohio's frost line (36"+) to eliminate frost heave and settling.
Built for Generations
Whether selecting laminated columns or perma-columns, your structural frame is engineered to stand upright for decades.
Comparing Structural Column Systems
Explore the structural specifications, soil considerations, and benefits of each column system available for your JT Pole Barn build.
Glue-Laminated Columns (Nail-Lam & Glue-Lam)
Premier Choice for Longevity & StraightnessEngineered by bonding three or four #1 pressure-treated 2x6 or 2x8 dimensional lumber plies together with structural adhesive and mechanical fasteners. The bottom portion in contact with soil/concrete is treated to heavy retention standards (.60 CCA), while the top remains untreated for superior stability.
Key Advantages
- Superior strength and dimensional stability (will not warp, twist, or cup)
- Stronger than equivalent solid timber posts
- Treating chemicals penetrate 100% of individual wood plies
- Easier to notch for truss connection interlock
Solid Treated Timber Posts (6x6 / 8x8)
Traditional Solid Timber ConstructionSolid single-piece timbers treated with CCA or MCA wood preservatives for ground contact (.60 retention). Used traditionally across rural Ohio for smaller agricultural shelters and basic storage sheds.
Key Advantages
- Time-tested traditional post-frame component
- Cost-effective for basic equipment storage buildings
- Heavy solid wood mass for impact resistance in livestock areas
Perma-Column Precast Concrete Systems
100% Rot-Free Concrete Foundation BaseCombines 10,000 PSI precast concrete columns that extend above ground level with steel bracket connections that elevate the wood column entirely out of the soil. Eliminates wood-to-earth contact permanently.
Key Advantages
- Zero wood in contact with soil or moisture
- Self-draining steel bracket assembly
- Backed by manufacturer lifetime structural warranties
- Ideal for high water table or clay soils in Ohio
