Two ways to work with us

We supply buildings and we install them, or we supply you the kit

Buy the whole thing turnkey and our crews stand it up on your slab, or take delivery of a bolt-together kit for your own crew. Same engineering behind both.

What we build

Large-format building types

We specialize in projects starting at 5,000 sq ft. Below is the work we do every week — pick the closest match and we'll engineer around your exact use, equipment and site.

Warehouses & Distribution Centers

Warehouses & Distribution Centers

10,000 – 200,000+ sq ft · 20'–40' eave

Clear-span storage and logistics space engineered up to 200'+ wide, with dock heights, drive-through bays, and column-free racking aisles.

Distribution centers, 3PL space, and manufacturing overflow. We engineer for racking layout, dock-door spacing, sprinkler loads, and your local snow and wind code before a single piece of steel is cut.

Manufacturing & Industrial Plants

Crane bays to 20+ tons · 24'–45' eave

Crane-ready industrial frames with bracket-mounted runways, heavy collateral loads, and tall eaves for process equipment.

Barns & Agricultural Buildings

Barns & Agricultural Buildings

5,000 – 40,000 sq ft · 14'–24' eave

Steel-framed barns, hay and equipment storage, livestock housing and shop barns built to outlast a pole barn by decades.

Red iron replaces posts, so the interior stays open, the frame does not rot at grade, and the building carries real snow load. Lean-tos, sliding doors, and open bays are engineered in.

Indoor Sports & Pickleball Facilities

6–20 courts · 24'–35' clear height

Column-free courts for pickleball, basketball, volleyball, and multi-sport training with clean ceiling heights and LED-ready purlins.

80'–200' door openings · 18'–40' eave

Hangars framed for hydraulic or bi-fold door openings, with header design coordinated to your door manufacturer and tail height.
