At a glance
The build, by the numbers.
40′x30′x12′ Commercial Metal Building features vertical roofing and paneling, multiple doors, and is pictured in quaker gray with black trim. It includes delivery, installation, and comprehensive warranties.
At 40′ across, the span leaves usable floor on both sides of a center aisle. No windows are specified, so daylight is something to raise at quote if you want it. The most common thing we quote a 40′x30′x12′ for is a small contractor's shop with framed-opening front. Second most common: tenant-improvement-ready space.

What's it for
Same shell, very different jobs.
A 40′x30′ 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.
A level spot is enough. Concrete, asphalt and compacted ground all work, and the matching anchors for all three ship with the building. Mark out the full 40′ x 30′ footprint and check it for level before delivery day — uneven ground is the one thing that reliably slows an install down.
It is the leg height, not the tallest point. 12′ runs from the base rail to the eave, where the roof meets the 30′ sidewall; the ridge is higher again because of the roof pitch. For anything driving into a 40′ x 30′ x 12′, the door opening is the real limit anyway.
This one is specified with (1) 10′x10′ garage Door, (1) 10′x8′ garage door. That is the opening itself, so measure whatever has to drive through against the door rather than against the 40′ width. Door sizes are not fixed — if what you are parking is tight, say so on the quote, because adding or resizing an opening up front is cheaper and cleaner than cutting one in later.
Yes to delivery and install, no to site prep. The crew brings and erects the 40′ x 30′ 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.
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 40′ x 30′ building. Separately, the install itself is warranted 30 days, so anything that looks wrong when the crew leaves should be raised inside that window.
It is not a fixed size. Starting from this 40′ x 30′, width changes in 2-foot steps and length in 5-foot steps, and the 12′ legs move a foot at a time. Give us the size you need and we quote that one.
Reviews
Owners say it best.
Real, verified Google reviews from owners who bought their building from us, straight from our business profile.
View all reviewsWe 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.
