Metal Barns
Frequently asked questions
-
What barn door options are available?
A common choice for metal buildings includes durable steel sliding barn doors, available as single or bi-parting systems. These doors provide wide, precise openings for easy access with equipment, vehicles, produce, and feed.
For similar large access needs, overhead or roll-up doors are also popular options, offering varying operational benefits and security. Sizes are typically customized to suit specific building requirements. Most barn buyers opt for one of the following standard door sizes:
Door type Door sizes Typical application Sliding doors 10' to 14' wide and 12' to 14' high Small storage barns Overhead doors 12' to 24' wide and 12' to 16' high Most barn applications Roll up doors 12' to 24' wide and 12' to 16' high  Most barn applications Hydraulic doors 24’ to 40’+ wide by 14’–18’+ high to clear large tractors and equipment Large machine sheds and repair shops NOTE:
Doors and windows must be set at least 2 feet from corners and the roof eave to preserve structural support, ensure proper load transfer, and maintain framing clearance, while simplifying installation. This spacing also protects the thermal envelope and weather barrier, reducing moisture intrusion, thermal bridging, and code compliance risks.

How much does it cost to build a metal barn?
The average cost to build a metal-framed barn will range from $25 to $50 per square foot. Barn costs largely depend on the structure's complexity and the type of foundation required. For example, a simple 30×40 barn with a dirt floor can start at $28,000, while a large 10,000 sq. ft. farm machinery shed can cost around $200,000 to build.
Item Square Foot Cost Barn building kit (shell) $15-$25 Foundation $3-$10 Construction $5-$10 Interior finishing $0-$20 -
What is better a pole barn or metal building?
A pre-engineered metal building offers greater durability and larger clear spans (unobstructed interior space) compared to a pole barn. While pole barns can be more cost-effective for simpler designs, a metal building typically offers faster construction, greater strength, and lower long-term maintenance costs (no replacing rotten wood or re-painting required). Your final choice depends on your project's specific requirements and available budget.

What are my options for installation?
When it comes to erecting your building, you have three options.
Do-it-yourself (DIY). We only advise going this route for smaller buildings (under 2,000 square feet) and for those with previous construction experience.
Self-manage. With a self-managed outline, you are responsible for hiring and managing the various sub-trades, including the concrete company for the foundation, the steel erectors to construct the kit, plumbers, electricians, etc.
Hire a General Contractor (GC). For a completely hands-off option, consider hiring a GC who will manage the entire design on your behalf, from pulling permits and installation to the final inspection. Expect to pay 10-20% for a GC's services.

Can you insulate a steel framed barn?
Yes, you can absolutely insulate a metal barn to enhance comfort and energy efficiency. Insulating a metal building helps regulate interior temperatures, reduce heating and cooling costs, and prevent condensation that can lead to moisture issues.
Standard insulation options include fiberglass batts, rigid boards, and spray foam, each offering varying levels of thermal performance.
See our metal building insulation page for more details.
