The build, by the numbers.

This 54′x40′ metal barn provides 2,160 sq. ft. of storage space, with 12′ gables, two 8′x7′ roll-up doors, a walk-in door, and two 24"x36" windows. It is perfect for vehicles, tractors, livestock, and more.

At 54′ across, the span leaves usable floor on both sides of a center aisle. 54′x40′x12′ is a size that usually goes up as a hay barn with vertical drive-through center. Second most common: a wash rack.

What's it for

Same shell, very different jobs.

A 54′x40′ 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 54′ x 40′ footprint and check it for level before delivery day — uneven ground is the one thing that reliably slows an install down.

Eave height. On a 54′ x 40′ x 12′ that means 12′ of straight wall before the roof starts to pitch up, so usable height at the walls is 12′ and the center is taller. Measure your equipment against the eave figure if it sits near a sidewall.

$26,745 covers the building, the delivery and the install crew. It does not cover site work — leveling the 54′ x 40′ 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.

Two covers on two clocks. The steel frame under this 54′ x 40′ 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.

It is not a fixed size. Starting from this 54′ x 40′, 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.

Two different parts. The frame is the tubing carrying the load of this 54′ x 40′ x 12′ — 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.
