The build, by the numbers.

This 12′x21′x7′ fully open A-frame horizontal roof carport features a galvanized steel frame (14g) and 29g steel panels. It is ideal for providing shade and protection for vehicles or outdoor equipment.

Nothing is framed for drive-in access as listed, so an opening or overhead door is sized at quote. 12′x21′x7′ is a size that usually goes up as a lumber and pallet cover next to the shop. It also gets ordered for 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.

Questions

Good to know.

A specialist can walk you through this exact build over the phone in a few minutes.

No concrete required. A 12′ x 21′ x 7′ 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.

It is the leg height, not the tallest point. 7′ runs from the base rail to the eave, where the roof meets the 21′ sidewall; the ridge is higher again because of the roof pitch. For anything driving into a 12′ x 21′ x 7′, the door opening is the real limit anyway.

Yes. The 12′ x 21′ x 7′ 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.

Yes to delivery and install, no to site prep. The crew brings and erects the 12′ x 21′ x 7′; you provide a level, cleared spot for it to land on. The price shown is a start point rather than a final invoice, because certification requirements and any added doors or openings change it.

The 20 years figure is rust-through on the frame, which is the structural cover and the one that matters over the life of a 12′ x 21′ building. Separately, the install itself is warranted 30 days, so anything that looks wrong when the crew leaves should be raised inside that window.

This page prices the 12′ x 21′ x 7′ as built, but width moves in 2-foot steps, length in 5-foot steps and leg height in 1-foot steps. Tell us the footprint you actually need and we price that build instead.

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.
