Plan a new storage facility or expand an existing property with steel self storage buildings from ALLSteelBuildings.com. National Building Supplies, LLC. is a nationwide distributor, helping customers plan building dimensions, unit layouts, doors, panels and finishes around their projects.

Self storage building kits planned around your unit mix
A useful starting point is the number and sizes of units you want to offer. Include building width, length and eave height, along with door sizes, access requirements and any planned expansion. If your layout is still being developed, share the information you have.
Discuss drive-up storage, climate-controlled storage requirements or a combination of uses with our team. Insulation, heating and cooling, interior layouts and other project requirements should be reviewed together when defining the building scope.

Building options and finishes
- Framing layouts selected for the building dimensions and intended use.
- Roof and wall panel profiles, including standing seam roof options where specified.
- Door and trim choices for the storage layout.
- Panel and trim colors to coordinate the appearance of your facility.
- Insulation requirements for buildings planned for temperature control.
Review roof panel options, wall panels and building color charts. Confirm the selected products, finishes and applicable warranty terms in your quote.

Boat and RV storage buildings
Oversized storage requires attention to vehicle dimensions, door clearance and interior space. We also supply steel boat and RV storage buildings. Tell us the largest vehicles you expect to accommodate and the opening sizes you need.

What affects the price of a self storage building?
Building dimensions, the number of buildings and units, framing, doors, panels, insulation and delivery location affect the quote. Compare the written scope of each proposal and budget separately for site work, foundations, erection, permits and utilities as applicable. See our steel building pricing guide for a quote checklist.
