The Ozark Closers build spec.

How to read this page.

The spec below is what goes into every Ozark Closers red-iron building. It's the same across barndominiums, workshops, shops, warehouses, and event barns — because the frame system is the same. What changes between projects is size, plan, and finish tier. Below you'll find:

• The dried-in package: what we deliver at handoff on every job.
• What's not in the dried-in number (so nobody's surprised at the site).
• Turnkey add-ons: what the interior finish package includes.
• Materials & specs table: gauges, grades, PSI, spacings, warranties.
• Codes & engineering: what your building is stamped for.
• Options and upgrades you can request before signing.

Dried-in package — what every job includes.

The scope below ships on every Ozark Closers build, whether you stopped at Dried-In or continued into Turnkey. Line items are worded the way they show up on the contract.

Turnkey — what the interior finish package adds.

Turnkey coverage runs across Missouri and northeastern Oklahoma out through Tulsa. Under one contract, our crew handles the steel and slab, and we hire and manage the trade subs on our paperwork. The interior finish schedule follows the Silver / Gold / Platinum tier system so the allowance for every material line is priced in writing before we buy anything.

• Interior framing — stud walls, headers, and blocking framed to plan
• Electrical — panel, circuits, outlets, switches, and lighting to allowance
• Plumbing — supply, DWV, fixtures to allowance
• HVAC — system sized and installed to plan (mini-split, central, or hybrid)
• Insulation — walls and ceilings, R-value per plan and climate zone
• Drywall — hung, taped, floated, textured, and painted
• Flooring — LVP, tile, wood, or polished concrete to allowance
• Cabinets & counters — kitchen and baths to Silver allowance by default
• Appliances — range, dishwasher, fridge, hood, and disposal per finish schedule
• Interior doors & trim — solid-core or hollow doors, base and casing
• Final punch, cleaning, and handoff

Materials & specs table.

Standard specs for the primary structure. These get adjusted up (never down) if your engineered plan calls for it — the number on your contract already reflects what's stamped for your site.

System	Standard spec
Primary frame	Red-iron rigid-frame columns and rafters, factory primed. Manufacturer red-iron (General Steel or Capital Steel), stamped and engineered for the specific site.
Frame steel grade	ASTM A529 / A572 Gr. 50 for primary members. ASTM A36 for base plates and connections.
Roof panel	26-gauge PBR panel, Galvalume AZ-50 substrate, standard paint finish with 40-year paint warranty.
Wall panel	26-gauge PBR panel, Galvalume AZ-50 substrate. 24-gauge upgrade available.
Purlin / girt spacing	Typically 5 ft on center for purlins, 6-8 ft on center for girts. Engineered to snow / wind loads.
Fasteners	Self-tapping screws with rubber EPDM sealing washers on all exterior sheeting. Structural bolts to spec at frame connections.
Insulation (dried-in)	Foil radiant barrier or fiberglass batt in wall and roof cavities per plan. Continuous R-13 minimum for shell.
Slab	4" concrete slab standard, 5-6" thickened turn-downs at column locations. 3,000 PSI minimum concrete. Rebar or wire mesh per engineered plan.
Vapor barrier	6-mil polyethylene under slab, lapped and taped at seams.
Anchor bolts	ASTM F1554 Gr. 36 or Gr. 55 anchor rods, set to manufacturer template with survey verification before pour.
Windows	Vinyl frame, double-hung, slider, or fixed. Low-E dual-pane glazing. Argon fill optional.
Exterior doors	36" insulated fiberglass or steel. Adjustable threshold, kick plate, weatherstripping.
Overhead doors	Insulated sectional (turnkey with opener) or non-insulated (dried-in add-on). Sized per plan.
Paint / finish system	PBR panels ship with Silicone Modified Polyester (SMP) paint film, 40-year warranty. Kynar 500 (PVDF) upgrade available for coastal / high-UV / premium builds.
Warranty on paint film	40-year against chip, crack, flake. 30-year against fade (Delta E under 5).
Warranty on structural steel	50-year manufacturer warranty on primary red-iron frame.
Delivery timeline (dried-in)	Typically 8-16 weeks from slab pour to dried-in handoff, depending on site conditions, kit lead time, and weather.

Codes & engineering.

Every Ozark Closers building is engineered and stamped for the specific site. That means:

• Wind load. Designed to the ASCE 7 exposure category and 3-second gust speed for your site. Residential builds typically 115 mph exposure C, higher on ridges or open ground.
• Snow load. Ground snow load per your county. Missouri Ozarks 10-15 psf, higher on north-facing sites. Tennessee mountain sites can hit 20+ psf.
• Seismic zone. Standard sites in the four-state region are Seismic Design Category A or B. New Madrid corridor sites are re-engineered as needed.
• Building code. Residential barndominiums built to IRC. Commercial / event-barn / warehouse builds to IBC. Foundation to ACI 318.
• Stamped drawings. Manufacturer-supplied and engineer-of-record stamped for your state. Delivered to you and to your permit office.
• Permit support. We hand off the stamped set and stay on the phone with the permit office if they have questions. Permit fees are the owner's cost, called out in the contract.

Options & upgrades.

These are the requests we see most often. All are priceable before signing so they land in the fixed number on the contract.

Exterior

• Kynar 500 (PVDF) paint upgrade on roof and/or walls — coastal, high-UV, and premium builds
• Standing-seam roof upgrade in place of PBR panels
• 24-gauge wall panels (heavier than standard 26-gauge)
• Wainscot in a second color (bottom 3-4 ft)
• Additional windows or larger window sizes
• Additional overhead doors, larger sizes, or insulated bays
• Covered porches, lean-tos, or shed roof extensions
• Dormers or gable overhangs beyond standard trim
• Gutters and downspouts (standard on turnkey, optional on dried-in)

Insulation & envelope

• Closed-cell spray foam upgrade (replaces batt for higher R-value)
• Continuous rigid insulation outboard of purlins
• Radiant barrier under roof panel
• Concrete slab insulation (rigid foam under and at slab edge)

Slab & foundation

• Thicker slab (6" or 8") for heavy-equipment shops
• Fiber-reinforced concrete instead of wire mesh
• Hydronic radiant floor tubing rough-in (before pour)
• Basement, storm shelter, or crawlspace foundation instead of slab-on-grade

Structural

• Higher wind or snow load rating beyond code minimum
• Interior clear-span requests (no interior columns)
• Mezzanine framing pre-engineered into the primary structure
• Crane rail or hoist support if the shop needs it

Ask any red-iron builder these three questions.

If you're comparing quotes, print this page and take it to your other bids. See if they can match the spec, and specifically ask:

1. Whose red-iron are you quoting? Manufacturer name, kit number, and engineered stamp state.
2. Who's actually erecting? Their crew or a broker's crew? Same faces every week?
3. What's fixed at signing? Get the exclusions list in writing before you sign. "Everything except..." is where surprise change orders live.
