Metal Barns

Custom metal barns are more durable than traditional pole barns and have little to no maintenance. They are also resistant to mildew, rot, and insects. In addition, you'll have lower insurance costs due to the fire resistance of steel, and the highly weathertight building envelope will protect your livestock, hay, and machinery in all weather conditions.

Why Choose a Metal Barn?

American-made, I-Beam steel framing, custom-engineered in factories across North America.

Metal barns are incredibly strong and durable, engineered to meet your specific local codes for wind, snow, and seismic loads. Our manufacturers offer structural and paint warranties of up to 30 years. And these structures aren’t susceptible to pests or rot or the warping and cracking that can happen with timber-framed buildings.

The bolt-together building format offers an enormous degree of flexibility in terms of barn access. Choose from sliding, roller, and bi-fold door options to accommodate large machinery. Custom door placement also allows you to maximize barn storage space.

Precision engineering ensures your barn building will fit together precisely the first time and enables fast deployment for either professional contractors or DIY builds.

And you can quickly adapt to future growth. Simply remove the end wall sheeting, pour a new slab, and add any number of 20 or 25-foot bays.
