The words on a metal building quote, explained by someone who learned them the hard way
My order form used a dozen words I nodded along to. Each one carried a price or a risk. Here is what they turned out to mean.
Where this comes from
My project record
Definitions below are a customer’s working understanding, checked against my own contract and what happened on my lot. Where a term has a precise engineering meaning, ask your engineer or county inspector; this list is to get you through the sales call without being talked past.
Certified building
A building supplied with site-specific engineered plans stamped for your location’s wind and snow loads, meant to pass county inspection. Non-certified buildings come without stamped plans. My order was certified, which is why the $3,000 plan line and the 20-week plan lead time existed, and why the county inspected the footings against those plans.
Vertical roof
Panels run from ridge to eave so water and debris shed downward, versus regular or A-frame horizontal panels. Vertical is the upgrade and the one most sellers push for larger buildings. My 50×80 was vertical roof, vertical sides and ends.
Gauge
The thickness of the framing tube or the panel steel. Lower numbers are thicker. 14 gauge framing is the heavier standard option; 12 gauge is heavier still. Mine was 14 gauge.
Leg height and ladder-leg baserail
Leg height is the wall height to the eave; mine was 16 feet, an $8,400 line. Ladder-leg baserail is a doubled base rail at the bottom of tall legs. Buildings over about 13 feet tall or 30 feet wide are where the contract starts requiring a telehandler.
Lean-to
A lower, attached roof section off one side or the back. Each is priced separately with its own height, gable, side closure and slab. My two lean-tos added about $18,350 to the building and two extra pads to the concrete.
Frame-out
The framed opening for a door, priced per opening. The door itself is separate. My order has ten garage door frame-outs and no garage doors.
Telehandler
A telescopic forklift used to lift trusses and panels into place. On my order it was “customer provided” at $0 for one week. It is the piece of equipment the whole telehandler dispute on this site is about.
Engineered plans / site-specific blueprints
Drawings stamped by an engineer for your building at your address, including the foundation sheet with footing sizes. They are what the county inspects against, and they are what a concrete contract should reference by sheet number.
Footer / footing
The thickened concrete under the slab edge and under columns that carries the building’s loads into the ground. Size comes from the engineered plans. “1x1” on my concrete contract meant 12 by 12 inches; the plans said 14.
Strip footer
A continuous footing along a wall line, as opposed to a pad under a single column. My contract had 47-foot and 62-foot strip footers under the lean-to lines.
PSI
Pounds per square inch, the specified compressive strength of the concrete at 28 days. 3,000 psi is a common residential standard; 3,500 was my upgrade. It is only verified if someone tests it.
Vapor barrier / 6 mil
Plastic sheeting under the slab, measured in thousandths of an inch. Six mil is the common spec. It keeps ground moisture out of the slab and shows up as the shiny layer under the rebar in my pre-pour photo.
Control joint
A saw cut or tooled groove in the slab that creates a weak line so shrinkage cracks happen there instead of at random. A crack running across a panel and through the joint, as in photo P-03, is the kind the joint was supposed to prevent.
Owner-builder / owner exemption
The legal status of a property owner who acts as their own general contractor and swears to personally manage the job. Pulling the permit as the owner puts you in this role whether or not you are actually managing anything.
Qualifier
The individual who passed the licensing exam and under whose name a company’s general contractor license is held. When you verify a license, verify the qualifier too.
Certificate of insurance (COI)
A one-page summary from an insurance agent showing a company’s general liability and workers’ compensation coverage, limits and dates. Ask for it to be sent by the agent directly.
Retainage
A percentage of each payment, or of the total, held back until the work passes final inspection. The thing my payment schedule did not have, and the thing a safer one is built around.
Why a customer wrote this
In February 2026 I signed a $98,750 contract with L&G Building & Concrete of Asheboro, North Carolina. By September I had a cracked slab, damaged plumbing and half a steel frame. This site documents it, with the contract, photos, texts and public records. The resources exist so the next buyer does not need to learn the same things the same way.
