At a glance

The build, by the numbers.

This 20′x80′x12′ A-frame steel garage features a fully enclosed design with eight skylights to brighten the interior. The garage also includes a convenient 10′x10′ door for easy access.

It is 4 times as long as it is wide, which lends itself to a row of bays instead of a single open floor. As configured there is no drive-in opening — that gets added and priced when you quote it. 20′x80′x12′ is a size that usually goes up as a light manufacturing floor with utility runs. It also gets ordered for rental units.

What's it for

Same shell, very different jobs.

A 20′x80′ 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 20′ x 80′ x 12′ cover anchors to concrete, asphalt or compacted ground, and the right anchors for whichever you have are included. What matters is that the 20′ x 80′ area is level and clear when the crew arrives.

On this 20′ x 80′ x 12′ the 12′ 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 to delivery and install, no to site prep. The crew brings and erects the 20′ x 80′ x 12′; 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.

Two covers on two clocks. The steel frame under this 20′ x 80′ x 12′ 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.

This page prices the 20′ x 80′ x 12′ 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.

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.
