Steel Storage Units

Storage at scale — to rent out, or to fill yourself.

This isn't a backyard shed — it's storage as a building. A steel storage building is a larger, partitioned structure that goes one of two ways: a multi-unit self-storage facility you rent out by the door, or a single big utility building where you keep a fleet, machinery, a collection, or serious overflow. Either way it's engineered steel, built to code, and sized to hold real volume behind roll-up doors.

As a self-storage investment, steel is what makes the numbers work — a building can hold 20 to 30 individual units behind their own roll-up doors, goes up in a couple of months instead of half a year, and starts collecting rent that much sooner. As a private utility building, the same clear-span steel swallows RVs, boats, equipment, and inventory a small shed never could. Factory-direct, stamped for permitting, and built for the load either job puts on it.

The storage lineup

Storage buildings, unit-ready or wide open.

Set the footprint and the door layout — a row of unit doors for a rental facility, or one big opening for a utility building. Every build is engineered to your plan.

Rental facility or private storage?

The two use cases build differently. Tell a specialist whether you're renting units or filling it yourself, and we'll spec the partitions, doors, and certification to match.

Two ways to use it

A rental business, or your own overflow.

Steel storage buildings serve two very different buyers. Both need volume and roll-up access; the difference is whether the doors are yours or your tenants'.

01
Self-storage facility

One building partitioned into 20–30 individual units, each with its own roll-up door and lock — a rentable, income-producing asset.

02
The unit mix that rents

A blend of 5×5 to 10×30 units — roughly a third small, half medium, a fifth large — is the layout operators find fills fastest.

03
Fleet & vehicle storage

One big clear-span building for work trucks, trailers, or a car collection — secured under a single roof.

04
RV & boat storage

Tall, deep bays that keep RVs and boats out of the UV and weather, whether for yourself or as a rental line.

05
Ag & equipment

Machinery, implements, and inventory in a column-free building that a small utility shed could never hold.

06
Business overflow

Seasonal stock, records, and equipment off-site of the main operation, in a secure, code-built structure.

Which build is yours

Rental facility vs. private storage — spec'd differently.

Sizes & starting prices

How big is a steel storage building?

Storage buildings start where sheds leave off — 20 feet wide and up — and scale to 50×100 and beyond for a full facility or a large utility building.

The right size depends on your unit mix or what you're storing. Search or scroll the sizes below, hover any one for what it fits, the SKU, and the price — then talk layout with a specialist.

For a rental facility we help plan the unit mix and door count; for private storage we size the clear span and doors to your fleet or equipment.

Two ways to pay

Own it sooner, pay it monthly.

Private storage builds often qualify for financing or no-credit-check Rent-to-Own; a self-storage facility is an income asset usually matched to conventional or commercial financing. A specialist will point you the right way.

We are building a barndominium and they delivered the shell on schedule. Our contractor said the framing was straighter than most stick-built shells he sees.

Loafing shed for the horses showed up exactly when they said it would. The crew leveled and anchored on uneven ground and didn't try to charge extra.

Hurricane-rated anchors and engineer-stamped drawings were ready when our county asked. Permit went through the first time.
