Pole Barn Roof Truss Spacing

Pole barn truss spacing.

Pole barn roof truss spacing.

Large span trusses require multiple pickup points using a spreader bar on the crane. Attic trusses are great for living space or storage space. 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. 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. In the 1980s post frame construction companies commonly used 60 single ply trusses. Pole barn construction spaces the trusses 8 feet apart or even up to 12 feet apart depending on the building design. Of course local building codes and regulations may also determine how many trusses and the spacing necessary for each post frame structure.

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. At the time pole barn builders were unable to hang or lift the trusses without any bending bowing. The more ply or layered material the stronger the truss. With traditional stick frame construction the trusses are usually spaced 2 feet apart.

Typically larger trusses 72 and 80 were two ply. 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.
