Agricultural Buildings

Agricultural metal buildings are primarily designed to shelter livestock, heavy farm machinery, and large crop yields. Because they serve varied and highly specialized functions on the farm, their construction designs differ from standard residential garages.

Wide clear-span bays for combines and tractors follow the same engineering thresholds covered in wide-span structures, and loafing sheds share framing logic with lean-to structures.

1. Barn Styles and Layouts

The most common structural configuration for an agricultural building involves a large Center Unit flanked by two Lean-Tos. This tripartite setup creates a massive covered footprint while visually mimicking traditional wood barns.

There are two main roof styles for agricultural barns:

• Classic Drop-Down Style: Features a distinct gap (the “drop”) between the roofline of the tall center unit and the peak of the adjacent lean-tos. The space between the two roofs is usually enclosed with vertical sheet metal (the gap enclosure), providing a classic “raised center” barn aesthetic.
• Continuous Roof Line Style: The roof flows seamlessly from the peak of the center unit all the way down to the eaves of the lean-tos without any vertical step-down. This creates a more streamlined look and eliminates the need for gap enclosures.

2. Loafing Sheds

Loafing sheds are open-faced shelters specifically designed for livestock (like horses and cattle) to escape extreme sun, rain, or snow while remaining in the pasture.

[!WARNING] Warranty Exclusions: Due to the high risk of damage caused by large livestock (kicking, rubbing, and bumping against the metal panels), loafing sheds typically do not carry structural warranties.

Key Characteristics of Loafing Sheds:

• Material Limitations: They are almost exclusively manufactured using 14-gauge steel tubing. If 12-gauge framing is required, the structure must usually be engineered and priced as a custom free-standing lean-to.
• State Availability: Due to zoning and engineering restrictions on three-sided structures in high-wind zones, standard loafing shed designs are heavily restricted and only available in select states (such as AR, IL, IN, KY, LA, MI, MO, NM, OH, OK, TX, and WV). In other regions, they must be engineered as custom free-standing lean-tos.
• Customizations: While simple, they can be upgraded with kick walls (to protect the lower siding from hoof strikes), walk-in doors, windows, gates, and even enclosed tack rooms for feed storage. Note that adding a tack room reduces the available sheltered area under the main roof.

3. Custom Configurations

Because agricultural needs are highly specific, almost every aspect of a barn can be customized. Equipment like combines and large tractors may require specialized leg heights or wide-span central bays — see customization options for how these upgrades are typically packaged.

Barn Layout Comparison

Style	Roofline	Best For
Classic drop-down	Visible step between center unit and lean-tos	Traditional barn aesthetic, distinct roof cavities
Continuous roof line	Seamless peak-to-eave slope	Streamlined look, no gap enclosure needed
Loafing shed	Open-faced, single or three-sided	Livestock shelter only, no structural warranty

Before ordering, confirm whether your parcel is zoned agricultural and check local permit requirements — agricultural exemptions vary widely by jurisdiction.
