Hardin’s Supplier for Pole Barns, Ag Buildings & Post-Frame Structures in Big Horn County

Big Horn County’s agricultural economy is among the most productive in eastern Montana — sugar beets, corn, hay, and cattle operations benefit from the Yellowstone River’s irrigation potential and the long growing season of the southern Yellowstone Valley. Contractors in Hardin build the grain storage facilities, equipment shops, hay barns, and livestock buildings that support this productive agricultural base. Post-frame construction is the dominant building method, offering the wide clear-spans and structural efficiency that serious ag operations demand.

Western Building Supply serves the Hardin market from our Wheatland, Wyoming manufacturing facility. We engineer every package for Big Horn County’s specific structural conditions — the Yellowstone Valley’s wind exposure, the ground snow loads of southeastern Montana, and the frost depths that determine column sizing for this part of the state. Our team builds packages that perform in the actual conditions at your job site.

The Hardin area’s proximity to Billings means contractors here often work across a wide territory, serving both the Big Horn County agricultural core and the communities south and east toward Wyoming’s border. We build complete packages that arrive ready to build, so your crew’s time is spent on construction, not waiting on materials.

When Hardin contractors need materials built for Big Horn County’s agricultural economy, they call Western.

Why Hardin Contractors Choose Western

Built for Eastern Montana Agriculture

Big Horn County’s irrigated agriculture and cattle operations need buildings that match the scale and seriousness of the economy. We supply wide clear-span grain storage, equipment shops with tall bay doors for large machinery, and livestock facilities engineered for eastern Montana’s winters. Our laminated columns are sized for the soil and frost conditions of the Yellowstone Valley, and our trusses span the widths that serious agricultural operations require.

Engineered for the Yellowstone Valley

The southern Yellowstone Valley presents specific structural conditions — the valley floor wind exposure, moderate but meaningful winter snow loads, and the temperature range that southeastern Montana delivers. We engineer every Hardin-area package for these conditions, so your building performs as designed through eastern Montana winters without issue.

One Supplier, Everything Included

We manufacture your entire post-frame package — custom trusses, steel roofing and siding in 45+ colors, laminated columns, and all hardware — at our Wheatland, Wyoming facility and ship it direct to your Hardin-area job site.
