We have a great amount of flexibility with post-frame buildings. Their designs offer attractive features such overhangs, steeper roof pitch, porches, etc. Because their walls don’t require interior supporting walls, you have open space inside to configure any why you want. You also get a lot of flexibility when it comes to exterior walls as well. It doesn’t have to be steel. Almost any type of façade can be used like brick, blocks, vinyl and wood siding.
Most people are surprised to learn that post-frame buildings have more strength than other building methods. There are a number of reasons for this:
- Columns in the ground add a lot of stability and wind resistance to a building.
- Horizontal connected posts from an extremely strong box that adds to wind and seismic resistance.
- The direct attachment of trusses to post frame buildings gives them a virtually impossible for a roof to detach from the building.
- The Diaphragm effect that is created by the post-frame structure allows them to flex under extreme stress instead of cracking or collapsing like would happen with other structures.
