Pole Barn Roof Truss Spacing

Pole barn construction spaces the trusses 8 feet apart or even up to 12 feet apart depending on the building design.

Pole barn roof truss spacing.

Of course local building codes and regulations may also determine how many trusses and the spacing necessary for each post frame structure. 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. The more ply or layered material the stronger the truss.

For many traditional stick frame builders trusses spaced 8 feet apart seems unnatural but thanks to the ingenuity of modern engineering it is a very common building design. Typically larger trusses 72 and 80 were two ply. Attic trusses are great for living space or storage space. Post frame roofs in severe weather conditions.

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. Hundreds of thousands of pole barns are in use today with trusses spaced every 12 feet or even more. For example you might use a 35 spreader bar on a 70 span truss. With traditional stick frame construction the trusses are usually spaced 2 feet apart.

In the 1980s post frame construction companies commonly used 60 single ply trusses. Large span trusses require multiple pickup points using a spreader bar on the crane.
