Delivery, certifications & load requirements
This 40x80 commercial storage building gives you 3,200 sq. ft. of enclosed steel space for inventory, equipment, fleet vehicles, machinery, tools, materials, farm supplies or business operations.
The 40-foot width gives you room for work areas, storage rows and equipment access. The 80-foot length gives you the depth needed for commercial storage, drive-in access, shop use or divided interior sections. With a 20-foot side height and an estimated 25-foot peak height, this building has the clearance needed for taller doors, lifts, racking, trucks and larger equipment.
It has a vertical roof, 4 garage doors, 2 walk-in doors and windows for access, light and day-to-day use. The vertical roof helps rain, snow, leaves and debris move off the building better, which matters on a structure this size.
Every building is custom made. You can change the size, height, colors, doors, windows, insulation, anchors, panel layout and certified wind or snow options based on your property, business use and local code needs.
Delivery and professional installation are included. Call Garage Buildings to get your 40x80 commercial storage building quote.
