Post Frame Buildings
Post Frame Builders for Mankato, MN
Post frame is the method behind most barns, sheds and shops in this part of the state. Tall laminated columns carry the roof, girts tie them together, trusses span the width, and a steel skin covers the whole frame. Since the columns carry the load, the walls can stand tall and the inside stays open. It goes up faster than a building on a block or poured foundation.
Two choices shape the building: how it is anchored and how it is engineered. Columns can be set below the frost line or mounted on a slab with brackets, each suiting different soils, floors and budgets. Trusses and bracing are sized for snow and wind loads. The same method serves a farm shed, a contractor yard building, a self-storage row or a church hall.

Questions
Post Frame Buildings FAQs
Why is post frame faster to build?
There is less foundation work, since columns are set in the ground or on pads instead of a continuous wall. The frame goes up in large pieces and the steel goes on quickly. Weather still decides some of the schedule.
Should the posts be buried or sit on a slab?
Buried posts below the 42 inch frost line are simple and sturdy for most farm and shop buildings. Slab-mounted columns suit buildings with a finished floor and tight tolerances. Soil, use and budget decide it.
Why do two post frame buildings of the same size price differently?
Footprint, height, span, foundation type, doors, insulation and floor, plus the dirt work on your land. Two buildings of the same size can differ a lot by finish. A builder prices the exact list you give.
Can I run a business out of one?
Often yes, for storage, workshops and similar uses, subject to zoning and the building code for that use. Commercial occupancy can bring extra requirements, which we raise before the drawings so the design fits.
Is it okay to build on clay or sloped ground?
Yes, with attention to the pad. Clay needs a compacted gravel base and drainage, and a slope may need cut-and-fill. Posts adapt well to uneven ground, which is one reason the method is common on river bluffs.
