The build, by the numbers.

This 18′x30′x7′ carport features a vertical A-frame roof with a side entry. It includes (6) 45° Framed Openings- (3) per Side and (2) gable ends, providing ample space and protection.

Openings come framed and ready, with the doors chosen and priced separately when you quote it. The most common thing we quote an 18′x30′x7′ for is a truck and boat side-by-side under one cover. Second most common: drive-through firewood.

What's it for

Same shell, very different jobs.

A 18′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.

No concrete required. A 18′ x 30′ 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 18′ x 30′ area is level and clear when the crew arrives.

On this 18′ x 30′ x 7′ the 7′ 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.

It can be. Sides, ends or both can be panelled on an 18′ x 30′ x 7′, and that decision belongs on the quote rather than afterwards — panels fitted at the factory land better and cost less than a retrofit.

Yes to delivery and install, no to site prep. The crew brings and erects the 18′ x 30′ 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.

Rust-through on the frame runs 20 years. Workmanship on the install runs 30 days. They are deliberately different lengths because they cover different risks — the steel of this 18′ x 30′ x 7′ degrading, versus how it went together on your site.

It is not a fixed size. Starting from this 18′ x 30′, width changes in 2-foot steps and length in 5-foot steps, and the 7′ 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 18′ x 30′ 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.
