Fabric Hay Storage Buildings: Protect Your Forage Quality

Fabric Hay Storage Buildings

Engineered for Maximum Cubic Storage

In the world of hay, air is expensive. If you can’t stack to the rafters, you are paying for space you aren’t using.

Sealed engineering drawing

Each Fabric Hay Storage Buildings are delivered with a sealed plan, compliant with local building codes and ready for permitting.

Insurable

Because our buildings come with a sealed engineering plan, they’re easier to insure and integrate into your protective cover.

Oval tube

Our exclusive oval tube offers increased load resistance while reducing premature membrane wear, thanks to the absence of right-angle edges.

Custom Verticality

While competitors offer standard heights, MegaDome fabric hay storage buildings are engineered for high-density stacking. With center clearances reaching over 27′ 5″ (and custom designs exceeding 50′), you maximize your “cubic footprint,” keeping your cost-per-bale at an industry low.

The Clear-Span Advantage

Traditional barns are littered with support pillars that dictate where you can drive. MegaDome fabric hay storage building offers a 100% clear-span interior:

Storage Capacity Calculation: Model XP-HD (60' x 216')

Let’s look at the math for a fabric hay storage building 60′ x 216′ MegaDome XP-HD.

  • 12,960 sq.ft
  • 27.5 ft of center clearance
  • 15.3 ft of side clerance at 4′

Capacity Estimate - Round Bales

  • Bale Size: 5′ Diameter x 6′ Width (placed on ends or rolled).

  • Stacking Strategy: To ensure safety and airflow, we calculate stacking 4 bales high in the center and tapering to 2-3 high near the walls.

  • Total capacity: 1152 round bales
Note: This calculation allows for a “buffer” space for ventilation and machinery maneuvering. If stacking Large Squares (3′ x 3′ x 8′), the capacity increases significantly due to the lack of “dead air” between rounded edges.

Capacity Estimate - Rectangle Bales

  • Bale Size: 3′ x 3′ x 8′ 

  • Large rectangle bales are the gold standard for commercial hay transport and export. Because they stack like bricks, they take full advantage of the MegaDome’s vertical clearance and flat-wall profiles.

  • Stacking Strategy: Stacking the 8′ length perpendicular to the length of the fabric hay storage building.

  • Total capacity: 2646 large rectangles bales
Note: We assume a 12′ central driving aisle for the telehandler and 2′ of clearance from the fabric walls to ensure optimal airflow and prevent abrasion.
