Agricultural Buildings


Agricultural buildings are utilized for a variety of purposes. From farm storage buildings to animal shelters to riding arenas to equestrian centers National Building Supply, Inc. can accommodate all your building needs.

When it comes to protecting your farm equipment and livestock, metal buildings are sturdier and more durable than traditional post-frame buildings. A metal agricultural building can withstand harsh weather conditions and extreme temperatures, making it an ideal solution for many building owners.

National Building Supply, Inc. can maximize your usable square footage by designing a clear span metal building. Whether it's animal and equipment storage or horse stalls and aisles you are looking to incorporate into your building, we can customize to your needs.

This cross shaped stable distinctively designed to deliver future horse racing champsions is a thoroughbred as the equine mares that get the toyal treatment in this special facility. The barn has 20 holding stalls featuring tongue and groove oak panels that allow a typical 12' x 12' stall to be doubled in size to give a confined horse more movement. Four foaling stalls are 16' x 16' to allow for plenty of room. The foaling barn is an impressive structure adding a stately appearance to Spring Hill Farms.
