Good Regular
Curved-eave arched roof · horizontal panels
The factory-standard roof: rounded eaves and panels that run front to back. Economical cover when you want shade and rain protection without a gable peak.
Steel buildings
Steel buildings
A steel building from Carport.com is a prefabricated American-steel structure: galvanized 14-gauge frame (12-gauge upgrade), 29-gauge sheeting, and a clear span you park, store, or work in. Same mill as our metal buildings — this page is for shoppers who search “steel.” Get a local price from your ZIP. Delivery and professional installation are free on a level site.
Three roofs: Regular (good), A-frame (better), and Vertical (best) — required when length runs past 36 feet. Sides stay open, get half-walls, or close fully. Horizontal siding is the factory look; vertical siding is the upgrade. Roof and walls pick from twelve colors independently.
Installation available in most states. Certified wind/snow packages for permits. Kits if you assemble. A deposit holds the order; the balance is due at delivery.

Roof styles
Good, better, best — three steel roofs
Every steel building you design starts with a roof. These are the same three choices in the builder.
Good 
Better A-frame
Boxed-eave gable · horizontal panels
A classic peaked roof with boxed eaves. Horizontal panels stay the factory look; the A-frame sheds water better than a Regular arch.
Best Vertical
A-frame boxed-eave · vertical panels
The same A-frame shape with panels that run peak to eave. Rain and snow travel off the roof instead of across seams — the most durable roof we sell. Required in the designer when length is over 36 feet.
Designer rule: if length is greater than 36 feet, Vertical is required so the roof can shed water on a long run.
Walls and siding
Open, half, or fully enclosed steel
The frame is steel either way. Enclosure is how you use it: carport, pavilion, garage, or warehouse.
Open sides
No side sheeting. Maximum airflow, easiest access, lowest price. Still a full steel roof and frame.
Top half-walls
Sheeting on the upper half of each side. Shade and wind break up high while the lower opening stays clear.
Bottom half-walls
Sheeting on the lower half. Blocks splash, debris, and low wind while the top stays open for light and air.
Fully enclosed
Full-height side walls. Combine with closed ends, a roll-up door, and walk-ins for a lockable building. You can enclose one, two, three, or all four sides.
Horizontal siding (factory standard)
Panels run front to back, matching a Regular or A-frame horizontal roof. This is the default orientation in the factory and the lowest-cost wall look.
Vertical siding (upgrade)
Panels run bottom to top. Pair with a Vertical roof for a continuous “stripes down” building, or mix it on walls only. Vertical sheeting sheds water at the laps instead of across them.
Ends: open, gable, or closed
The front and back are independent of the sides. Leave them open for drive-through, add a gable (peak filled, opening below), or close them fully and put a roll-up on the front.
Doors and windows
Walk-in doors, roll-up garage doors, and windows go on enclosed sides and ends. Adding a door in the designer will close that wall automatically so the opening has something to sit in.
Colors
Twelve colors, roof and walls
Pick a roof color and a wall color independently in the designer. Names vary slightly by plant (for example Patriot Red vs. Barn Red) — the swatch is the same twelve codes. Request color samples if you want chips in hand.

Why steel
What a prefab steel building is for
Vehicle covers and garages
Open steel carports or enclosed steel garages — same frame, different walls and door package.
Shops and warehouses
Clear span, certified packages, roll-ups on any wall. Vertical roof on long commercial runs.
Ag and barns
Aisle plus lean-tos in steel that does not rot. Valley / Vertical roofs for hay country.
Backyard and storage
Shed-scale or garage-scale enclosed boxes. Steel instead of a wood kit you will stain forever.
Kits vs. installed
Installed on a level pad is the default. Steel building kits ship if you assemble.
Same as “metal buildings”
The industry uses both phrases. This page is the steel-keyword hub; metal-buildings is the metal-keyword hub. One catalog, two indexed doors.

Steel building questions
What is a steel building?
A prefabricated structure whose primary frame is structural steel and whose roof (and usually walls) are steel panels. Carport.com steel buildings use American 14-gauge galvanized frames, optional 12-gauge, and 29-gauge sheeting — the same system sold as metal buildings, carports, and garages.
Steel building vs. metal building?
Same product on this site. Shoppers use both phrases. Use this page if you searched “steel building”; use metal buildings if you searched “metal building.” Specs, designer, and install program are identical.
What gauge steel do you use?
Standard frame is 14-gauge galvanized American steel. 12-gauge is the upgrade for heavier wind or snow. Roof and wall panels are 29-gauge. Roofs are 3/12 pitch. Clearance is leg height, not peak.
Is delivery and installation included?
Yes, on a level building site, with installation available in most states. Deposit holds the order; balance is due at delivery. Steel building kits are available if you assemble.
Do I need a certified steel building?
If your county requires a permit, they often want engineered drawings or a certified wind/snow package. Those are available when you order.
Can I buy a steel building kit?
Yes. Same steel as an installed building, cut for you to assemble. Choose kit-only in the designer or call (855) 227-7678.
How do I get a steel building price?
The online builder shows a local price as you set size, roof, walls, and colors. Open any photo in the catalog to price that unit. Or call (855) 227-7678.
What is the warranty?
20-year rust-through coverage on the frame. Ask the phone team for current sheeting and paint terms.
