Metal Buildings for Sale | Custom Steel Buildings with Free Delivery & Installation

Absolutely. You control the size, roof style (Regular, Boxed-Eave, or Vertical), color, steel gauge, door and window placements, garage door sizes, lean-to additions, insulation, wainscoting, and more.

Changed your mind after installation? No problem. Our buildings are modular — doors, windows, insulation, lean-tos, and interior framing can all be added later without altering the original structure. A $50 return-trip fee applies to add-on orders under $795.

Very well. Our structures are rated for winds up to 180 mph and snow loads up to 90 psf, backed by stamped engineering drawings you can hand to your building department. These aren't marketing numbers — they're PE-certified load calculations specific to your region.

For the best severe-weather performance, go with a Vertical Roof. The panels run top to bottom so rain, snow, and debris shed straight off instead of pooling in horizontal ribs. Pair that with heavier-gauge framing and you've got a building that handles hurricanes, nor'easters, and heavy snow country.

A metal building can be installed on concrete, asphalt, gravel, or dirt as long as the surface is level within about 3 inches across the building footprint. We recommend concrete slabs for most applications, especially workshops, commercial buildings, and any structure housing heavy equipment.

Gravel pads should be at least 4 inches deep and extend at least 2 feet beyond the footprint on all sides. Every Keen's metal building is anchored to engineered specifications during installation: wedge bolts on concrete, mobile-home-style auger anchors on gravel and dirt, and mobile home anchors on asphalt.

Pro tip: add drainage grading to prevent standing water beneath the structure, and extend your pad at least 2 feet past the footprint for the best results.

No — concrete is not included in the base price of a Keen's metal building because it isn't always necessary. However, it can be added to your package and financing at an average cost of approximately $7.60 per square foot.

Concrete slabs are recommended for workshops, commercial buildings, and any metal building that will house heavy equipment or serve as a certified installation. Use our Concrete Pad Calculator to estimate the cost for your specific building size.

No — insulation is not included in the base price but can be added to your package and financing at an average cost of approximately $3 per square foot per surface (roof and/or walls).

Insulation is strongly recommended for heated or cooled spaces, workshops, and any metal building housing temperature-sensitive items. Combined with ridge or turbine vents and lighter-colored roof panels, insulation significantly reduces summer heat buildup inside the building. Use our Insulation Calculator to estimate costs for your build.

Yes. We publish every approval number on this page so you can verify them yourself. Roll-up doors, walk-in doors, windows, and roof/wall panels all carry active Florida Product Approval numbers tied to specific manufacturers and models.

Yes. Every building is stamped by a licensed Professional Engineer — Richard E. Walker, P.E. (Florida License No. 61240). Those stamped drawings spell out the exact wind and snow load ratings for your specific location, which is what your building department needs to issue a permit.

On the business side, we hold a Florida General Contractor License (CGC1533634) and carry active PE firm certifications in all 20 states we serve. Use the Licensing & Certifications widget above to look up our credentials in your state.

An uninsulated metal building with a dark roof in direct sun? Yes, it'll cook. But a few smart design choices fix that. Go with 12-foot or taller sidewalls so hot air rises above the work area. Pick a lighter roof color (white, tan, or light gray reflect the most heat). Add a ridge vent or turbine vent at the peak to exhaust trapped air.

If you plan to heat or cool the space, add insulation at the time of order — it's the single biggest upgrade for temperature control. Leave at least 4 feet of headroom above your tallest vehicle or piece of equipment so air circulates freely. Customers who follow these steps use their buildings comfortably year-round, even in Florida summers.

Keen's metal buildings ship standard with a 3/12 roof pitch, with optional 4/12 and 5/12 pitches available for steeper profiles. Regular roofs use a gentle rolled profile, boxed-eave roofs feature a traditional A-frame angle, and vertical roofs use the same pitch with vertically oriented panels for superior water and snow runoff.

A metal building can be used for just about anything that needs a roof, walls, and a solid floor. The clear-span interior and open layout make our steel buildings adaptable to virtually any residential, agricultural, or commercial purpose.

Customers use them for vehicle protection (cars, trucks, RVs, boats), workshops and hobby studios, secure weather-tight storage, agricultural shelters and hay barns, commercial warehouses and retail space, and recreational areas like outdoor entertaining spaces. The open clear-span interior means no center posts getting in the way, so you can reconfigure the space anytime your needs change.

We cover 20 states from Texas to New York, including the entire Southeast, Midwest, and Mid-Atlantic. Delivery and installation are on us across the full service area — no hidden fees.

Prefer to build it yourself? DIY metal building kits ship anywhere in the U.S. And if you want to see a building in person before you buy, stop by one of our 7 retail display centers in Florida and Georgia — walk inside, check the finish, ask questions face to face.
