Gauge is wall thickness, and it is the honest half of a price gap
Two quotes for the same size building usually differ here first. What each gauge is for, and when the answer is neither of them.
The numbers run backwards, which is why this is confusing
Gauge is the wall thickness of the square tube the frame is built from, and the scale counts down: 12 gauge is thicker than 14 gauge. Everybody who has bought steel knows that and almost nobody who hasn't does, so "14 or 12" reads like a model year rather than like the difference it is.
Same shape, same color, same building on the outside. More steel in the wall of every leg and every rafter on the inside.
This is usually where two quotes actually differ
When one quote for a 30x40 comes back noticeably under another, the frame is the first place to look and it is rarely mentioned in the headline number. Before comparing two prices, make both quotes say:
- Gauge of the frame, in writing.
- Tube or red iron.
- Panel gauge, which is a separate number from frame gauge and gets conflated constantly.
- Whether erection and delivery are in the figure or under it.
A cheaper quote is often a genuinely cheaper building, and sometimes it is the same building with less steel in it. Both are legitimate. Neither is visible from the price.
How to pick without a spec sheet
Ask what the building has to survive rather than what it has to hold. A carport that lives in open country takes wind on every side of it; the same cover tucked behind a treeline and a house does not. Storage that will never see a lift is a different building from a shop where something heavy hangs off the frame one day.
Tell us the site and what is going in it, and the gauge recommendation comes back with the quote. It is not a question you should have to answer before you get a number.
When the answer is neither
Gauge only applies while the frame is square tube. From 32 ft of width a building needs specific engineered plans and calculations rather than a generic plan set, and from 40 ft tube stops being the right tool. If you need a clear floor with no post in the middle at that width, the choice is not 14 versus 12 — it is red iron, and it is engineered rather than configured.
Under 40 ft with posts allowed, tube is the product, and you can lay it out yourself in the 3D builder.
The other things people ask
- I already have a concrete guy — why is a slab on my quote?Concrete is subcontracted to standing partners. You can keep your own pourer, and here is exactly what changes if you do.
- Vertical roof or A-frame — does it actually matter?Two hard rules rather than a preference: horizontal roofs stop at 31 ft, and insulation needs a vertical roof to go on.
- Do I need a permit, and who pulls it?Permitting is subcontracted to standing partners and managed by us. What we need from you, and what nobody can tell you over the phone.
- Why do 14 ft legs cost more than 12 ft?Taller legs mean longer wall sheet, more frame and more wind load. Tell us the tallest thing going inside and we will tell you the leg.
- Who actually puts it up — your crew or a sub?Erection is subcontracted, the same as permits and concrete. What you are buying is that the scheduling is our problem, not that there is no sub.
- How far do you deliver, and is it in the price?That is what the ZIP box on the quote form is for. Why it is separate, and why a quote without it is not a quote.
- What do you need from me to quote in 24 business hours?The clock starts when we have enough to price against. This is the whole list, so the first call can be the only call.
