The build, by the numbers.

This 12′x21′x6′ Regular Style Carport features a galvanized steel frame with 14g gauge and 29g steel panels. It includes a 30-day workmanship warranty, a 20-year rust-through warranty, and delivery with installation.

As configured there is no drive-in opening — that gets added and priced when you quote it. 12′x21′x6′ is a size that usually goes up as 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.

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 12′ x 21′ footprint and check it for level before delivery day — uneven ground is the one thing that reliably slows an install down.

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.

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 6′ 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.

Two different parts. The frame is the tubing carrying the load of this 12′ x 21′ x 6′ — 14-gauge galvanized steel. The panels are the skin screwed to it, 29-gauge steel. Lower gauge number means thicker steel, so the frame is always the heavier of the two. Compare frame to frame across quotes; that is the number that decides how a building stands up.

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.
