SINCE 1998 · SPECIALIZING IN 5,000+ SQ FT
Steel and metal buildings for sale — building kits, barndominiums, garages, warehouses and barns — delivered and professionally installed by our own crews across the continental U.S.
What we build
We specialize in projects starting at 5,000 sq ft. Below is the work we do every week — pick the closest match and we'll engineer around your exact use, equipment and site.
5,000 – 200,000 sq ft · 20'–40' eave
Clear-span storage and logistics space engineered up to 200'+ wide, with dock heights, drive-through bays, and column-free racking aisles.
Distribution centers, 3PL space, and manufacturing overflow. We engineer for racking layout, dock-door spacing, sprinkler loads, and your local snow and wind code before a single piece of steel is cut.

Crane bays to 20+ tons · 24'–45' eave
Crane-ready industrial frames with bracket-mounted runways, heavy collateral loads, and tall eaves for process equipment.
Red-iron frames designed around your equipment: top-running or underhung cranes, mezzanines, pit foundations, ventilation penetrations, and future expansion end walls.
Explore manufacturing buildings
80'x200' to 120'x300' · 16'–20' eave
Covered arenas sized to standard dressage and roping dimensions, with attached stall barns, wash bays, and viewing rooms.

Multi-tenant retail, strip centers, showrooms and service counters with storefront glazing, parapets, and street-facing panel and trim packages.
Steel-framed retail with the architectural front the site plan requires: parapet walls, canopy steel, storefront framing, and demising walls fabricated for however many tenants you are leasing.
Explore retail buildings
3,000 – 40,000 sq ft · 14'–24' eave
Steel-framed barns, hay and equipment storage, livestock housing and shop barns built to outlast a pole barn by decades.
Red iron replaces posts, so the interior stays open, the frame does not rot at grade, and the building carries real snow load. Lean-tos, sliding doors, and open bays are engineered in.
Explore barns buildings
6–20 courts · 24'–35' clear height
Column-free courts for pickleball, basketball, volleyball, and multi-sport training with clean ceiling heights and LED-ready purlins.
Court-count-first design. We lay out the playing surface, run-offs, and spectator space, then wrap the clear span around it so no column ever lands inside a court.
Explore indoor sports buildings
40'–100' door openings · 18'–40' eave
Hangars framed for hydraulic or bi-fold door openings, with header design coordinated to your door manufacturer and tail height.
Single-aircraft to corporate and municipal hangars. We coordinate door loads, jamb reinforcement, and airport authority submittals with your engineer of record.
Explore hangars buildings
14'–18' doors · 30'–60' unit depths
Revenue-driven storage buildings with tall drive-through bays, unit demising walls, and layouts tuned to rentable square feet.
Enclosed, canopy, and combination layouts. Built for class-A motorhomes and wake boats, with clear internal heights that keep every unit rentable.

5,000 – 40,000 sq ft · 16'–28' eave
Contractor yards, fleet maintenance, truck and diesel shops, and multi-bay retail service buildings with office build-outs.

Explore commercial shops buildings
5,000 – 15,000 sq ft · porches & lean-tos
Residential steel structures over 5,000 sq ft combining living space with shop, equipment, and RV bays under one frame.
Wrap-around porches, board-and-batten style panels, standing seam roofs, and shop space that stays a shop. Framed and engineered for residential code in your county.
Explore barndominiums buildings
10,000 – 100,000+ sq ft · 20'–40' eave
Insulated refrigerated warehouses and cold-storage distribution centers engineered for temperature control, heavy roof loads, and high-traffic dock operations.
Red-iron frames wrapped in insulated metal panel assemblies, with vapor barriers, cooler/freezer box integration, and dock-door layouts sized for refrigerated freight. Built to keep product cold and operations moving.

AMF Steel Buildings
Nationwide project reel
Every frame is an AMF building: engineered and stamped for its jurisdiction, fabricated as red iron, freighted to the site and — when you want it — installed by our crews.
Why owners trust AMF
We supply buildings, we supply kits, and we install them. From stamped engineering to final punch-walk, our process is built for large projects that cannot afford surprises.
Verified by building owners
Experienced steel erection crews
Since 1998
48 states served
Structural drawings stamped for your local wind, snow, and seismic loads.
Built to IBC, ASCE, MBMA, and AISC standards for commercial steel structures.
Primary rigid frames and secondary members fabricated to engineered shop drawings.
Freight coordinated straight to your job site anywhere in the lower 48.
Proof before you commit
See finished buildings from AMF job sites, hear from the owners who bought them, and know exactly how we move from footprint to final punch-walk before you request a quote.
“AMF handled the full process from stamped drawings to installation. The crew was on site when promised and the building came out exactly as quoted.”
“We bought a steel building kit for our project and the piece-marked steel made assembly straightforward. Their detailers answered every call.”
“Our large building needed a long clear span and AMF delivered. The supply-and-install approach let us focus on operations instead of coordinating subs.”
Tell us the use, the footprint, and the site. You get a real building quote with dimensions, openings, and color package — not a per-square-foot guess.
Stamped drawings engineered to the wind, snow, and seismic code of your exact jurisdiction, with anchor bolt plans for your concrete crew.
Red iron frames and panels rolled in your selected colors and gauges.
Freight coordinated to your job site anywhere in the lower 48, sequenced so the crew is never waiting on steel.
Take the kit and build it yourself, or let us install it with vetted steel erection crews we have worked with for years.
Design tools
Use the 3D designer to set the footprint, add overhead, hangar and walk doors, windows and wainscoting, then color it with our real panel palette and save a shareable link.
Why AMF
5,000 sq ft is where our engineering and installation crews are most competitive. Clear spans to 200'+ are routine, not an exception we have to engineer around.
You talk to the same people from quote to final delivery. No call center, no rotating rep.
Buy the engineered kit and install it yourself, or hand us the whole scope including installation.
Coverage on buildings and components, with SMP WeatherXL finishes on commercial and industrial panels.
Colorado offices, U.S. mainland production, and engineering stamped for the jurisdiction your building actually lands in.
