A variety of door options are available, including:

  • Overhead
  • Walk doors
  • Hydraulic doors
  • Bi-fold doors
  • Slider doors

Other additions include concrete flooring, metal roofing and waterproofing.

Machine Sheds

Lined Shop/Machine Shed Combo

These sheds combine the features of their lined shops and machine sheds. They are fully insulated to ensure comfort and energy efficiency.

Greiner’s Andy Duggan’s 104’ x 72’ x 18’ lined combo shop took first place in the National Fram Builder Association’s Building of the Year Awards for the Hobby Shop division. That particular project was created to store the customer’s snowmobiles, car trailer and dump trucks.

Cattle Barns

Greiner’s cattle barns are built with your needs in mind and include important features, like:

  • Concrete wall foundations: Provides a durable and reliable foundation for your structure.
  • Open sidewalls: Allows for natural ventilation to keep your livestock cool in the summer while providing fresh air.

Barns can be customized to your needs.

The company utilizes Kynar painted steel to preserve energy and reduce heat levels in the home.

High-strength, 29-gauge steel is used with the conjunction of machine-stressed lumber that has all been tested for strength and durability. Depending on the structure being erected, you can also choose:

  • Overhead doors
  • Insulated doors
  • Windows
  • Asphalt or metal shingles

Textrafine or spray foam can be used for insulation for cost effectiveness and to further insulate the structure. Posts are further supported using thermoplastic barriers to reduce moisture and oxygen from reaching the structure of the building.
