Pole Barn Trusses for Sale

Pioneered in the 1930s, pole barn construction has been a quick and economical method for adding outbuildings on farms as agriculture shifted away from manual labor to equipment-dependent and capital-intensive. This meant farmers needed an easy place to park and store their tractors, harvesters, and wagons out of the elements. Around North America, many pole-built structures are still readily seen in rural and industrial areas.

Wikipedia describes pole barns this way:

Pole buildings do not require walls but may be open shelters, such as for farm animals or equipment or for use as picnic shelters.

Enclosed pole buildings have exterior curtain walls formed by girts fastened to the exterior of the posts at intervals about 2 feet (0.61 m) on center that carry the siding and any interior load. The walls may be designed as a shear wall to provide structural stability. Other girt systems include framing in between the posts rather than on the outer side of the posts. Siding materials for a pole building are most commonly rolled-rib 29-gauge enameled steel cut to length in 32-or-36-inch (813 or 914 mm) widths attached using color-matched screws with rubber washers to seal the holes. However, any standard siding can be used, including T1-11, vinyl, lap siding, cedar and even brick. Using sidings other than metal may require first installing sheathing, such plywood, oriented strand board or boards.

On two walls, usually the long walls, the dimensional lumber girts at the top of the walls are doubled, one on the inside and one on the outside of the posts, and usually through-bolted with large carriage bolts to support the roof load. The roof structure is frequently a truss roof supporting purlins or laths, or built using common rafters. Wide buildings with common rafters need interior rows of posts. Sometimes rafters may be attached directly to the poles. The roof pitch of pole buildings is usually low and the roof form is usually gable or lean-to. Metal roofing is commonly used as the roofing and siding material on pole buildings.

The floor may be soil, gravel, concrete slab, or framed of wood.

When it comes to pole barn trusses, it’s always important not to cut any corners. As with any structure, roof trusses are a critical component. Polebarnsdirect.com says it’s important to design trusses with safety in mind. Some kits offer pole barn trusses that can be supposedly placed at a greater spacing than 4’ on center, but that can be dangerous. First of all, they are hard to set. Second, the greater spacing can displace the load, causing the trusses to fail more quickly.
