Here at Pole Barns Direct, we include only the best materials in our pole building kits. Our lumber is all #2 grade or better (SPF), and the load-bearing components are all southern yellow pine (SYP), a wood widely recognized in the building industry as one of the strongest, most versatile species. Its superior load-bearing capacity and fastener-holding ability make it ideal for pole barn construction.
The beam in your post frame building is a crucial component, which is why we use #1 SYP for this part of the framing. Because it’s carrying the entire load of the roof, we use a higher grade of wood to ensure the beam is as strong and straight as possible.
Our pole barn kits also include treated SYP posts, sized according to the height of the building. Our standard posts are 6×6, but we also offer 3-ply and 4-ply laminated posts.
Our treated lumber is CCA .60 treated. This treatment preserves the life of the lumber from decay, rot and insect damage. If the pole barn has adequate drainage around the post foundation it will last a lifetime.
