Pole Barn Roof Truss Spacing

Hundreds of thousands of pole barns are in use today with trusses spaced every 12 feet or even more.

Pole barn roof truss spacing.

Many post frame or pole barn construction use 8 foot spacing between trusses. For example you might use a 35 spreader bar on a 70 span truss. The practicality cost effectiveness and ease of construction of pole buildings is based upon efficient use of the fewest amount of materials to do the most work within safe engineering design. Of course local building codes and regulations may also determine how many trusses and the spacing necessary for each post frame structure.

Typically larger trusses 72 and 80 were two ply. Large span trusses require multiple pickup points using a spreader bar on the crane. Trusses 2 o c trusses can also be set 4 o c for steeper roof pitch appeal but eliminating attic storage and flooring building 1 and building 2 building 3 for similar attic area pics. At the time pole barn builders were unable to hang or lift the trusses without any bending bowing.

Pole barn truss spacing. Attic trusses are great for living space or storage space. Pole barn construction spaces the trusses 8 feet apart or even up to 12 feet apart depending on the building design. Post frame roofs in severe weather conditions.

Truss bracing temporary truss bracing is critical to ensure safety and to protect the integrity of the truss structure until permanent bracing is in place. The more ply or layered material the stronger the truss.
