Why Choose a Metal Barn?

  • Heavy-duty AZ‑55 Galvalume steel (55 % aluminum / 43 % zinc alloy) delivers up to 7× the rust resistance of standard galvanized panels, plus high thermal reflectivity for energy efficiency in diverse climates.

  • 100 % clear‑span design eliminates internal posts or trusses-maximizing usable space for hay, livestock, or equipment.

  • Versatile functionality: great for hay storage, equipment shelters, grain bins, and horse barns.

  • Naturally fire-, pest-, and mold-resistant, steel construction offers significant long-term savings versus wood-framed barns.

Metal Barn Design & Structure

Clear‑Span Mechanics & Sizes

  • Clear-span mechanics mean zero interior posts-providing open layouts for large machines, bale stacks, or open livestock pens.

  • Common sizes: 30×40, 40×60, 45×80, 60×140-from ~1,200 to 8,400+ square feet.

  • Built from AZ‑55 Galvalume steel with a 50,000 psi yield for maximum durability and snow load performance.

DIY Assembly & Installation Time

  • Assembly uses a floating foundation, requiring less excavation and ideal for rural sites.

  • All arches bolt together using a single fastener size-no welding required.

  • Installation can be completed in 3-5 days by a small team with basic tools.

  • Regional permitting varies, but most customers complete the design-to-installation process in under 8 weeks.

Use Cases & Applications

Equipment & Hay Storage

  • Protect tractors, plows, and harvesters from rain and UV damage.

  • Store hundreds of hay bales with sealed interiors and optional turbine ventilation to reduce mold risk.

  • Galvalume’s reflectivity helps reduce interior heat gain in warm climates.

Horse Barns & Livestock Shelters

  • Custom endwalls can accommodate sliding doors, stalls, and vents for airflow.

  • Insulation-ready frames allow year-round comfort for horses, cattle, or goats.

  • Steel avoids rot and splintering common in wooden barns, protecting animals and feed.

Pro Tip: A steel barn may cost more up front but often saves 30-50% in lifetime maintenance vs wood-frame buildings.

Cost, Snow Load & Planning Factors

  • Cost per sq ft varies by size, location, and design.

  • AgriBilt buildings are engineered to local code-handling snow loads from the Northeast to the Rockies, and wind loads in coastal or plains states.

  • Permits are typically required but simplified with AgriBilt’s pre-engineered plans and stamped drawings.

FAQs & Buyer Tips

Most kits can be installed in 3-5 days with a small team and basic tools.

Quonset styles are more DIY‑friendly and structurally self-supporting. Post‑frame barns use wood posts and can offer more traditional aesthetics.

Most customers use spray foam, fiberglass rolls, or insulated panels paired with vents or skylights.

Depending on stacking and bale size, you can typically store 250-300 round bales.

Avoid vague price locks or escalation clauses. Always review contract terms for delivery timelines and change order policies.
