24×30 / 30×40
Detached garage with one or two roll-up doors, a walk-in, and optional insulation. Most popular suburban size.
30×40 / 30×50
Wide bays, 12-foot eaves, electrical-ready. Add a swamp cooler or mini-split and you have a year-round workspace.
20×40 / 30×50
Tall sidewalls (12–14 ft) with extra-wide roll-ups so the slide-outs and ladders clear. Optional sealed slab to keep the rig dry.
40×60 / 40×80
Open or partially enclosed with vented ridge cap. Standard for hay storage, equipment shelter, and small livestock buildings.
40×80 / 50×100
Higher ceilings, wider clear-spans, multiple roll-up doors. Used as small contractor yards, fleet bays, and self-storage units.
30×50 / 40×60
Side-load equipment shelter for tractors, combines, sprayers, and oilfield service trucks. Open lean-to options available.
A metal building in the Oklahoma City metro has to do more than just shelter a vehicle, and that is exactly why we get the call. The lots in this part of the state run the gamut: 1950s ranches with a single-car attached garage that is now full of bikes and Christmas tubs, newer additions where the HOA only allows a 24-foot detached garage, and acreage outside the city limits where folks want a 40×60 shop with a lean-to for the tractor. Barn Brothers builds fully enclosed steel buildings — garages, workshops, RV barns, hobby shops, ag pole barns, and small commercial units — for property owners across central Oklahoma. We are not a carport company that bolts on walls; the entire structure is engineered as one weather-tight envelope from the ridge cap down to the slab anchors. Standard sizes run 20×20 single-bay garages up to 50×100 commercial clear-spans, with 24×30 personal garages and 30×50 workshops being the metro’s sweet spot. Vertical roofs are standard on enclosed buildings here because Oklahoma County winters bring just enough freeze-thaw to make horizontal-panel water management a long-term liability. Insulation, walk doors, garage doors, sliding barn doors, windows, and wainscoting are all a la carte on the same itemized quote, so you can spec a bare-bones unheated storage building or a fully finished, insulated, electrified workshop on the same call. Lead times currently run 3–6 weeks for non-certified, 5–8 weeks when we have to wait on stamped engineering for a city permit.

All prices delivered & installed in Garfield County. Standard 14-ga frame, 29-ga panels, vertical roof, mobile-home anchors. 12-ga frame, 26-ga panels, helical anchors, gutters, insulation, and additional door/window options are itemized add-ons. Steel pricing locked at deposit.
All doors come pre-hung in the building during install — no after-the-fact framing required. Roll-ups include the latch and J-channel; opener motors are optional and easy for any garage-door tech to retrofit later. Slider barn doors come with track, rollers, and stop pegs. Walk-ins are ADA-compatible 36″ standard.
Oklahoma summers run 95°F+ for weeks, and a couple of January cold snaps will dip into the teens. The right insulation spec depends on whether you’re storing things, working in there occasionally, or keeping it conditioned year-round.
Storage tier
Included in base price
Bare 29-ga panel. Fine for unconditioned storage of vehicles, equipment, hay, or seasonal stuff. Will sweat in spring/fall when warm humid air hits cold steel — condensation drips can rust tools sitting on the floor. Add a vapor barrier later if needed.
Workshop tier
Roof: $1.20–$1.40/sq ft · Walls: $0.95–$1.20/sq ft
Reflective foil-bubble-foil sandwich. R-value about R-7 effective with the air gap. Cuts radiant heat gain by ~35% in summer, ~25% in winter. Eliminates condensation drip. Most popular upgrade — turns an unworkable July shop into something you can spend an afternoon in with a fan running.
Conditioned tier
R-19 roof + R-13 walls: $2.80–$3.40/sq ft installed
Standard residential code-grade insulation with a continuous polyethylene vapor barrier on the inside face. Required if you plan to heat & cool with a mini-split or unit heater. Liner-panel finish is an extra $1.10–$1.45/sq ft for a clean white wall surface that holds shelving and looks professional.
Spray foam is a fourth option (R-6.5/inch closed cell) but we don’t install it — we refer local foam contractors who can spray after we set the building. Closed-cell foam is the gold standard for buildings that need to hold conditioned air long-term, but expect $4–$7/sq ft installed for the foam alone.
Wind rating
140 MPH
Certified to handle Garfield County straight-line wind events and severe-thunderstorm gust fronts.
Snow load
35 PSF
Engineered to Oklahoma snow-load minimums for Enid and surrounding communities, with vertical roof drainage standard.
Permits
Usually required
Inside Enid city limits, fully enclosed metal buildings almost always require a building permit and an engineer-stamped drawing set — that is true for any structure over 200 sq ft in most Oklahoma jurisdictions. We provide the stamped drawings as a $375–$650 add-on. Unincorporated Garfield County typically waives the permit for residential ag-use buildings on parcels over 5 acres.
Enid sits in Garfield County, near Vance Air Force Base, with road access via US-412. The 2018 IBC wind speed map puts most of this region in the 115 MPH ultimate design wind zone (Risk Category II, Exposure C), which converts to roughly a 90 MPH nominal basic wind speed on engineered drawings. For a fully enclosed building — which catches more wind than an open carport because it cannot let air pass through — that wind load is the single most important spec on the engineering set.
Standard 14-gauge framing with mobile-home anchors and 29-gauge vertical-roof panels rates to about 90 MPH on a fully enclosed structure — right at the minimum. Our certified buildings are engineered up to 140 MPH wind and 35 PSF snow load depending on bracing, anchor pattern, frame gauge, and door layout. On enclosed buildings 30 feet wide or larger, we strongly recommend going certified at minimum 130 MPH and upgrading to 12-gauge frame — the additional door openings cut into the wall’s shear capacity, and the certified package offsets that with extra X-bracing in the wall panels.
Anchoring matters even more on enclosed buildings. A 30×50 enclosed building presents roughly 600–800 sq ft of broadside wall area to a perpendicular gust — that translates to 8,000–12,000 lbs of lateral load on the anchor system during a 70 MPH gust. Most of Garfield County sits on clay-loam soils that lose 30–50% of their pull-out strength in dry months. We use 48-inch helical/auger anchors as the standard on any enclosed building over 30 feet wide on dirt, concrete wedge anchors at 24-inch o.c. on slabs, and J-bolt embeds where you have a freshly poured slab we can spec our anchor pattern into. Expect $400–$1,200 in anchor upgrades over base “mobile home anchor” pricing on enclosed builds. Cheap insurance.
Vertical roof is mandatory on enclosed buildings. Design ground snow load for this part of Oklahoma is roughly 8 PSF under ASCE 7-16. Boxed eave and regular roofs trap snow and ice between the panel ribs — on a 40-foot-wide enclosed building that adds 1,500–2,500 lbs of point load during a typical Oklahoma ice storm. Vertical sheds it clean. We will not quote a regular or boxed-eave roof on any enclosed building 24 feet wide or larger, period.

Every Enid build carries frame, panel, and workmanship warranties, with engineer certification standard on most enclosed builds for permits or insurance.
Frame warranty
20 years
Every leg, rafter, brace, and purlin warranted against rust-through and structural failure for 20 years from install. Hot-dipped galvanized 14-ga steel standard, 12-ga upgrade available on enclosed buildings (recommended for any build over 30′ wide). G90 zinc spec — the agricultural building workhorse standard.
Panel warranty
10 years
29-ga vertical-roof panels carry a 10-year manufacturer warranty against fade, chalk, and chip-through. Silicone-modified polyester paint over galvalume substrate. 26-ga upgrade extends panel warranty to 20 years (+8–12% panel-line cost) and is highly recommended on commercial / ag buildings that take regular impact from equipment.
Workmanship
1 year
Anything our crew installs is warranted for 12 months from completion. Loose bolts, misaligned panels, leaks at door penetrations, anchor failure on level ground, sticky roll-up tracks — we come back and fix it on our dime. Most claims hit in the first 90 days, almost always after the first big windstorm.
After 20+ years of building across Oklahoma, here’s the straight talk on three options Enid buyers actually consider for an enclosed building.

“I called three companies about a 30-by-50 workshop for the home place. Two of them quoted me higher and wanted six weeks just to get a stamped plan together. Marcy had me a written quote the same afternoon and the crew was here 26 days later. Whole thing went up in two and a half days. The roll-up door tracks were a hair off when they finished — they came back the next Friday on their own and adjusted them, no charge, no argument.”
★★★★★
“Bought a fifth wheel last spring and needed something to keep the sun off it year-round, with sides so the dust does not coat everything. The rent-to-own option was the only way I could swing it. The lady on the phone walked me through the whole thing twice without making me feel dumb for asking. The crew showed up at 7:45 a.m. like they said they would, and the foreman shook my hand before he left. Little things matter.”
★★★★★
“Needed a 40-by-80 building for the equipment yard before fall. Called several others — all of them wanted 10 to 12 weeks. Barn Brothers had it standing in 35 days flat. The crew showed up at 7 a.m., were eating lunch in the truck by noon on day one, and packed up at 4 on day three. We have had it through one round of those April storms now and it has not creaked. Worth every dollar.”
