Steel Frame Barndominium Kits
A steel frame barndominium is a barndominium built on a rigid steel frame, the red-iron, pre-engineered I-beam frame used for commercial metal buildings, rather than the post-frame or pole-barn construction most barndominiums use. It is the strongest, most durable way to frame a barndo, and it gives you the wide, open interior that makes combined living and workspace possible.
Universal Steel of America manufactures and ships the steel barndominium shell as a complete kit: the frame, the panels, and everything needed to put the structure up. Your contractor erects it on your slab and finishes the inside. We are the manufacturer of the steel shell, not a home builder, which is exactly why the structure is engineered, certified, and built to last. The frame is the same rigid system behind our metal frame buildings, supplied as a ready-to-build steel building kit.

Options and configurations
Any Size and Clear Span
Any width, length, and eave height you need, with wide clear-span interiors and no forced interior columns, so your living and workspace layout is yours to decide.
Doors and Windows
Framed openings sized and reinforced wherever you want them, for overhead and walk doors, large windows, and patio or garage entries.
Steel building accessoriesInsulation
A steel barndominium needs proper insulation to be comfortable and efficient to live in. We specify an insulation system to your climate, for temperature control and to prevent condensation.
Metal building insulationRoof and Wall Panels
A choice of panel profiles and finishes, including the highly recommended standing seam roof, to suit how you want the exterior to perform and look.
Insulated metal panelsColors and Finishes
A full range of panel colors and trims, with the option to clad sections in brick, stone, or stucco for a more finished, residential exterior.
Metal building color chartsMezzanines and Lofts
Add a loft open to the floor below, or a full second floor of living space, engineered into the frame from the start.

What's included
Red-Iron Primary Framing
The main columns and rafters that form the rigid frame, fabricated from heavy steel I-beam sections, the “red iron” that gives the building its strength and clear span.
Secondary Framing
Purlins, girts, eave struts, and bracing that span between the main frames, carry the panels, and brace the structure against wind. Steel framing also gives you a solid, true surface to attach interior walls to.
Roof and Wall Panels
The steel envelope, in PBR, standing seam, or insulated profiles and a range of colors, backed by a long-term finish warranty. The exterior look of your barndominium, weatherproofed.
Openings, Trim, and Bolts
Framed openings sized for your doors and windows, complete trim, and all the fasteners and anchor bolts. Everything needed to put the shell up arrives marked and ready to assemble.
Why choose a steel frame barndominium?
Barndominiums are popular because they combine a home and a workspace under one roof, affordably and quickly. Framing that home in steel rather than wood is what makes it last.
Built to outlast the weather and the pests
A steel frame does not burn, rot, warp, or feed termites, and red-iron steel resists rust and corrosion. Your barndominium is engineered to the wind, snow, and seismic codes at your site, so it stands up to the climate and needs very little maintenance over its life.
Wide-open, flexible floor plans
Steel spans far. Where post-frame construction puts posts every 8 to 12 feet, a steel frame clears 20 to 30 feet or more between columns, so you get a genuinely open interior to lay out however you like, living space on one side, a shop or garage on the other, a loft above, with few interior walls forced on you.
Fast to put up
The whole shell is engineered and fabricated in advance, factory-punched and ready to bolt together. The structure goes up far faster than a stick-built home, so your contractor can move on to the interior sooner.
Customized to your plan
Any width, length, eave height, and roof pitch, with framed openings wherever you want doors and windows, and room for a mezzanine or full second floor. You bring the plan or a sketch; we engineer the shell around it.
Steel Frame vs Post Frame Barndominium
The biggest decision when you plan a barndominium is how it is framed. Most barndominiums are post-frame, also called pole-barn, construction built on wooden posts. Universal Steel builds the other kind: a rigid steel frame. Here is how they compare.
Construction and foundation
Post-frame uses large wooden posts set in the ground or on piers, a pole-barn foundation that keeps upfront costs down. A steel frame is built from pre-engineered red-iron I-beams bolted together, set on a poured concrete slab with proper footings.
Strength and durability
Wooden posts can rot, shift, and attract termites over the years, even with modern brackets. A steel frame does not burn, rot, or feed pests, and it is engineered to your local wind, snow, and seismic codes, with less long-term maintenance.
Clear span and floor plan
Post-frame posts sit 8 to 12 feet apart, so interior walls have to work around them. A steel frame spans 20 to 30 feet or more between columns, giving you wide-open, flexible floor plans, which is what makes a true open-concept living and workspace possible.
Upfront cost and long-term value
A steel frame is usually a larger upfront investment than post-frame, because of the engineering, the heavier steel, and the concrete foundation. Post-frame is the cheaper way to start. What steel gives back is strength, clear span, durability, and lower maintenance over the building’s life, and steel structures often qualify for lower insurance premiums.
If you are building for the long term and you want the most durable, open, low-maintenance barndominium, a steel frame is the stronger choice. It is the only kind we make.
We Build the Shell, You Finish the Inside
It is worth being clear about what Universal Steel supplies. We are a steel building manufacturer, in business since 1995. We design and engineer your barndominium shell in house, then ship it to your site from the plant closest to you, complete with engineered structural stamped drawings. Your builder or erection crew puts the shell up on your slab, and your contractor handles the interior fit-out, the framing of rooms, plumbing, electrical, and finishes that turn the shell into a home.
That division is a strength, not a limitation. You get a structure engineered and certified to a high standard, the same standard behind the buildings we have delivered for national operators including Walmart and branches of the U.S. military, and the freedom to finish the living space exactly how you want. We hold IAS accreditation and an A+ BBB rating, and we ship across the US and, internationally, the Caribbean, Puerto Rico, South America and Africa.
Steel Frame Barndominium Kits questions
What is a steel frame barndominium?
It is a barndominium built on a rigid steel frame, the red-iron, pre-engineered I-beam frame used for metal buildings, rather than the post-frame or pole-barn (wooden post) construction most barndominiums use. The steel frame is stronger, more durable, and spans wider, which is what gives a barndominium its open, flexible interior.
Steel frame or post frame barndominium, which is better?
Post-frame is cheaper to start and uses wooden posts on a pole-barn foundation. A steel frame costs more upfront but does not rot, burn, or feed termites, is engineered to your local loads, spans far wider for open floor plans, and needs less maintenance. For a durable, open barndominium built for the long term, a steel frame is the stronger choice.
Does Universal Steel build the whole barndominium or just the shell?
We engineer and ship the steel shell as a complete kit, the frame, panels, openings, trim, and fasteners, with engineered structural stamped drawings. Your erection crew puts the shell up on your slab, and your contractor handles the interior fit-out, the rooms, plumbing, electrical, and finishes. You get a manufacturer-engineered structure and full freedom over the living space.
Can a steel barndominium have a second floor or loft?
Yes. Because the frame is engineered to carry the load, we can design in a loft open to the floor below or a full second floor of living space. It is built into the frame from the start rather than added on later.
Do I need insulation in a steel barndominium?
Yes. Insulation is important in any steel building you plan to live in, both for comfort and energy efficiency and to control condensation. We specify an insulation system suited to your climate as part of the shell.
How much does a steel frame barndominium cost?
The cost depends on the size, clear span, eave height, steel gauge, the loads it is engineered for, insulation, and finishes, and the shell is only one part of the budget, your contractor's interior fit-out is separate.
