Metal Buildings for Shops, Machinery, & Livestock

Add value to your operation with a structure that provides endless opportunity. A pole barn building suits any agricultural demand, from livestock shelters to equipment storage. Post-frame structures can be used as greenhouses, processing areas, crop storage, equestrian barns, machine sheds, fully-insulated shops, riding arenas, and a whole lot more.

Post-frame Buildings for Farms

Farm buildings need proper ventilation. Pole barn designs easily accommodate ventilation features, like overhead doors, vents, and cupolas. Our custom pole barns are highly versatile, and can be easily expanded and repurposed to accommodate future demands. If your farming intentions grow or change, you can modify your building to accommodate new needs.

  • What is a post-frame building? What is a pole barn?
    A post-frame building, also referred to as a pole barn, is a type of building characterized by its unique construction method. Construction starts by installing vertical posts or poles into the ground. These posts create the foundation that supports the building’s roof and walls.
  • What can I use a pole barn for?
    Pole barn buildings can be used as almost any traditional structure. Some popular uses for post-frame buildings include: agricultural storage, insulated workshops, garages, horse barns, and residential homes.
  • What are the benefits of pole barn homes?
    Pole barn homes hold many advantages over traditional homes. They are extremely customizable due to their lack of load-bearing walls. A post-frame home is a cost-effective housing solution. Additionally, post-frame construction is usually quicker than traditional construction.
