About out Fabric Buildings for Agricultural and Equestrian

Fabric covered buildings offer a cost-effective solution to traditional buildings. National Building Group Inc. is proud to have partnered with industry leader Calhoun. Our innovative solutions ensure the strongest and safest structures in the industry. At NBGI, we go beyond industry standards with features that set us apart from the competition, including unique building profiles, hot-dipped galvanization and innovative engineering procedures.

The difference is in our structure: NBGI-Calhoun Fabric Buildings use cutting edge technology, including the 3D Finite Element Non-Linear Analysis, which considers the snow, rain, wind, and seismic conditions at the building location. This technology allows us to deliver the strongest building for your unique location. In addition, our clear span truss system creates a barrier-free interior up to 200 feet, allocating more space for storage and allows for your equipment to move effortlessly within your building.

All NBGI-Calhoun’s Super Structure frames and other critical components are hot-dipped galvanized (HDG) after fabrication. This means you have the full protection of the HDG, inside and out, welds and all- nothing is exposed. The hot-dip galvanization process creates a metallurgical bond between the base steel and zinc-iron alloys. The result is a protective coating harder than the base steel and has up to 4 times the amount of zinc protection in that of in-line galvanizing. The HDG process is time tested. There is a reason why engineers in Canada spec hot-dip galvanized steel in building high traffic bridges, it lasts! View Hot-Dip Fact Sheet
