Pole barn roof trusses are wooden beams set in a triangle pattern that support the roof. Trusses come with every pole barn kit. Also, they help make sure the pole barn will be stable and safe.
How Pole Barn Roof Trusses Work
Builders design pole barn trusses to make the best use of wood. The amount of wood looks fairly small. However, the way builders arrange it makes trusses strong. As a result, they can carry the weight of a metal roof and snow, and they can stand up to strong winds.
How Far Apart Should Trusses Be?
Builders and engineers have different opinions on truss spacing. Some recommend placing trusses close together. Others believe you can design a pole barn with trusses farther apart that is just as safe.
Snow Load
One factor that affects truss spacing is snow load. It varies with the region where you build. Also, the type of roof and whether you heat the pole barn both affect snow load.
Wind Load
The design of your trusses also depends on how much wind your area gets. The location of the building site matters. So do obstructions, such as trees or other buildings, that would shield it from the wind. In addition, trusses near the ends of the roof need a higher wind load rating than trusses in interior zones.
Dead Load
The engineer or builder who designs your pole barn will also consider dead load. This means the weight of the building and roof themselves. Dead load affects how much stress the truss beams carry.
