Hay barns built for the Oklahoma wind.

Truss-frame and rafter-frame hay barns engineered to clear a round-bale stacker, vent August heat, and stand against the storms that roll out of Texas every spring.

/ What we build

Hay Barns for Oklahoma.

A working hay barn isn't a shed with a tall door — it's a piece of equipment. Eave height has to clear a fully extended stacker. The ridge has to dump heat the moment a breeze starts moving. The anchorage has to hold against the same wind that flattens the line of cedars on the south fence.

Every Greene Builds hay barn is engineered to those numbers, not estimated from a brochure. We grade and pour the monolithic slab, erect the truss or rafter frame, and finish with 26-gauge roof and wall panels on a schedule we hand you in writing before we break ground.

/ Standard options

What you can spec.

Monolithic or pier-and-beam foundation
26-gauge roof in standard or premium colors
Open-eave or closed-eave detail
Vented ridge cap for prairie heat
Side lean-tos for equipment cover

Frame recommendations

Up to 60 ft span → Steel Truss Frame (the workhorse choice)
Beyond 60 ft → Rigid Frame I-Beam

/ Questions we get

Hay Barns, answered.

Common questions we get from Oklahoma farm owners on this exact build type.

How tall does the eave need to be for a round-bale stacker?+

We typically build 16–18 ft eaves on working hay barns — perfect clearance for standard 3-high round-bale stacking with the stacker fully extended. We'll size to whatever stacker you actually run.

Do you do open-eave or closed-eave?+

Both — but for a hay barn in Oklahoma, open-eave with a vented ridge is almost always the right call. It lets the August heat out instead of cooking the top bales.

How long does a 50 × 100 hay barn take?+

From signed contract to keys, plan on 8–12 weeks depending on permitting and weather. Foundation pour is one to two weeks, steel erect is another two to three on a typical job.

Can I add a lean-to later for equipment?+

Yes — we pre-engineer the frame on request so a lean-to bolts cleanly without rework. Tell us at quote time and we'll spec it that way from the start.
