Pole Barn Roof Truss Spacing

Hundreds of thousands of pole barns are in use today with trusses spaced every 12 feet or even more. Of course local building codes and regulations may also determine how many trusses and the spacing necessary for each post frame structure. With traditional stick frame construction the trusses are usually spaced 2 feet apart. Typically larger trusses 72 and 80 were two ply.

For example you might use a 35 spreader bar on a 70 span truss. Many post frame or pole barn construction use 8 foot spacing between trusses. 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. At the time pole barn builders were unable to hang or lift the trusses without any bending bowing.

Large span trusses require multiple pickup points using a spreader bar on the crane. Attic trusses are great for living space or storage space. 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. In the 1980s post frame construction companies commonly used 60 single ply trusses.

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