Metal Barns and Pole Barns in Missouri

While a pole barn is a more traditional option, metal barns will far outlive a pole barn. In fact, many people have been using the term “pole barn” to refer to metal barns! While a pole barn has wooden poles in the ground to help stabilize the roof and sides, a metal barn is built on a flat and level foundation. 

Wooden poles present several challenges— especially with the changing weather in Missouri. For something that’s going to last a long time and work just as hard as you do, choose a metal barn.
