80×100 Metal Building
8,000 sq ft 14 to 20 ft eave
An 80×100 metal building gives you 8,000 square feet of column-free floor space under one clear-span roof, making it one of the most practical large footprints for warehousing, light manufacturing, distribution, and big commercial or recreational uses. Universal Steel of America is a US manufacturer: we engineer, fabricate, and ship the steel, so the frame that arrives at your site is built for your job rather than pulled off a generic shelf.
Every 80×100 building is engineered to your local snow, wind, and seismic code, and we ship from the plant closest to your site anywhere in the US and internationally across the Caribbean, Puerto Rico, South America and Africa. The 80-foot clear width is the real advantage at this size: it opens up forklift lanes, equipment bays, and full sports courts with no interior columns in the way. Professional erection is available as an optional service when you want a turnkey result.

Popular uses for a 80×100 Metal Building
Warehouse and distribution
With 8,000 square feet and an 80-foot clear span, this size fits rack rows, wide forklift aisles, and loading operations with no interior columns to work around. The full width keeps storage and material flow efficient. A taller eave adds vertical pallet capacity for high-bay racking.
Metal warehouse buildingsLight manufacturing and industrial
The column-free floor suits assembly lines, fabrication bays, and production equipment that need clear room to move. Frames can be engineered for overhead cranes and heavier collateral loads. It is a common footprint for growing industrial operations.
Industrial steel buildingsLarge commercial and retail
An 80x100 works as a showroom, multi-bay auto or service facility, or a small strip of commercial units under one roof. The open span lets you lay out the interior however the business needs. Storefronts, glazing, and finished offices can all be added.
Commercial steel buildingsGymnasium and indoor sports
The 80-foot clear width fits a full basketball court with sidelines, plus room for bleachers or multi-court recreation layouts. Schools, churches, and municipalities use this size for gyms and rec centers. Taller eaves give the ceiling height that court sports need.
Gymnasium buildingsCold storage
The clear-span shell adapts well to insulated cold-storage and refrigerated facilities where uninterrupted floor space and controlled temperatures matter. Wall and roof systems can be specified for higher R-values. It is a practical size for regional cold-chain operations.
Cold storage buildingsWhy 80 feet of clear span matters at this size
The defining feature of an 80×100 is the 80-foot column-free width paired with 100 feet of length. That combination suits operations that need wide, uninterrupted floor area: rack rows and forklift aisles in a warehouse, assembly lines in a light manufacturing shop, or a full hardwood court with run-off in a gym. Because the rigid steel frame carries the load, you keep all 8,000 square feet usable instead of designing around posts.
Built for commercial, industrial, and institutional work
At 8,000 square feet, this size lands squarely in commercial and institutional territory. It works as a distribution hub, a cold-storage shell, a multi-bay shop or auto facility, or an agricultural equipment barn. Taller eave options give you room for mezzanines, overhead cranes, or high-bay storage.
Living quarters and barndominium options
If you are pairing work space with living quarters, an 80×100 has the floor area to do both, though a build this large is most often commercial. We can engineer the shell for a barndominium layout when that is the goal. See our barndominium buildings page for how living-quarters projects are planned and finished.
80×100 Metal Building questions
How much does an 80x100 metal building cost?
Industry-typical pricing for an 80x100 metal building runs roughly $10 to $20 per square foot for an engineered steel shell, or about $80,000 to $160,000. A finished turnkey project, including foundation, erection, and finishes, usually lands around $20 to $40 per square foot. Your final price depends on engineered loads, eave height, finish, and site, so a building-specific quote is the only accurate number.
How many square feet is an 80x100 metal building?
An 80x100 metal building is 8,000 square feet. Because it uses a clear-span frame with no internal columns, all 8,000 square feet are usable open floor space, which suits large machinery, forklift access, court sports, and a wide range of commercial operations.
How much does an 80x100 shop cost?
As a workshop or multi-bay shop, an 80x100 typically falls in the same range as other uses at this size: about $10 to $20 per square foot for the engineered shell and roughly $20 to $40 per square foot finished. Adding insulation, large overhead doors, and interior offices raises the total. We provide a firm engineered quote once the spec is set.
What is the difference between an 80x100 pole barn and a steel building?
A pole barn uses wood posts set in or on the ground with a lighter structure, while an 80x100 steel building uses an engineered red-iron frame designed to your local snow, wind, and seismic code. At an 80-foot width, steel delivers a true column-free clear span that post-frame construction cannot match, along with longer-lasting durability and a finish warranty on the panels.
What eave height should an 80x100 metal building have?
Most 80x100 buildings use an eave height between 14 and 20 feet. Warehouses and high-bay storage favor the taller end for racking, court sports need clearance overhead, and equipment shops are often comfortable lower. The right eave depends on your use, and we engineer the frame to suit.
