The build, by the numbers.

Simple yet effective, this 12′x21′ open carport with a 6′ eave height features a regular roof and sturdy galvanized steel construction. It includes delivery, installation, and warranties covering workmanship and rust-through.

Nothing is framed for drive-in access as listed, so an opening or overhead door is sized at quote. The most common thing we quote a 12′x21′x6′ for is a lumber and pallet cover next to the shop. Second most common: outdoor pet kennel cover.

What's it for

Same shell, very different jobs.

A 12′x21′ gets specified differently depending on what goes in it — door placement, openings, leg height, whether it closes in. Tell us the job and we'll spec it to that instead of handing you a blank form.

No concrete required. A 12′ x 21′ x 6′ cover anchors to concrete, asphalt or compacted ground, and the right anchors for whichever you have are included. What matters is that the 12′ x 21′ area is level and clear when the crew arrives.

On this 12′ x 21′ x 6′ the 6′ is eave height — base rail up to where the roof meets the sidewall, which is the height of the legs. The peak sits higher because the roof is pitched. Check clearance against the eave and against the door opening, never against the peak.

Yes. The 12′ x 21′ x 6′ is listed here as an open structure, but whether it closes in is settled at quote — along with door placement, openings and leg height. Doing it at order time is cheaper and cleaner than adding panels to a building that is already standing.

$1,695 covers the building, the delivery and the install crew. It does not cover site work — leveling the 12′ x 21′ area, or pouring a slab if this one is going on concrete. Those happen before install day. Options and local wind and snow certification are the two things that move the number.

Two covers on two clocks. The steel frame under this 12′ x 21′ x 6′ carries a 20 years rust-through warranty. Workmanship is covered 30 days from installation — the window for raising anything the crew got wrong on the day. Corrosion is the long one; install quality is the short one.

It is not a fixed size. Starting from this 12′ x 21′, width changes in 2-foot steps and length in 5-foot steps, and the 6′ legs move a foot at a time. Give us the size you need and we quote that one.

Frame gauge is structure, panel gauge is skin. On this 12′ x 21′ the frame is 14-gauge galvanized steel and the panels are 29-gauge steel. Because the scale runs backwards, the smaller number is the thicker steel — which is why the frame figure is the one worth checking when two quotes look the same.

We are building a barndominium and they delivered the shell on schedule. Our contractor said the framing was straighter than most stick-built shells he sees.

Loafing shed for the horses showed up exactly when they said it would. The crew leveled and anchored on uneven ground and didn't try to charge extra.

Hurricane-rated anchors and engineer-stamped drawings were ready when our county asked. Permit went through the first time.
