Metal Outbuilding Kits

Sizes We Recommend


One of the great advantages of steel buildings is their versatility, and perhaps no building type exemplifies this more than an outbuilding. Steel outbuildings can be used for a variety of purposes, including RV storage, a personal workshop, storing heavy machinery or professional equipment, and more. Our outbuildings are designed to fit your specific needs, and the efficiency of steel construction means your outbuilding project is finished on time and on budget.

Design Flexibility

An out building can serve many purposes, which makes steel construction the best fit for your new building. Our building kits are designed according to use, whether you need storage space, a personal workshop, or perhaps both. Unlike basic out buildings found at big-box hardware stores, General Steel’s building kits aren’t one-size-fits-all. They’re the product of a collaborative effort between you and our experienced design team.

Our team works directly with you to zero in on the right dimensions, configuration, components, and accessories for your building. Door types and sizes, windows, gutters, skylights, insulation, color scheme and more – an out building from General Steel reflects your function and style.

Long Term Value

General Steel’s building kits likely require a higher initial investment than an out building found at a big-box hardware store. Our buildings are made with higher quality steel and provide a long-term solution for your storage needs.

While the initial investment is likely to be higher, an out building from General Steel provides better protection from the elements than a basic out building. In the case of an extreme weather event, a basic out building may be lost or damaged, leaving your valuables exposed and the need for another purchase. Considering the extensive warranty protection offered from General Steel, a steel out building is the more valuable option in the long run.

What businesses can I start with a warehouse?

Warehouse kits are versatile buildings that are equipped to support business of many kinds. We’ve worked with e-commerce companies, server farms, consignment stores, indoor dog parks, fitness centers, microbreweries, and more.

Why is a prefabricated building the best choice for a warehouse?

A prefabricated building provides the best value due to its design versatility, strength, durability, and efficient construction. A warehouse requires a high degree of customization, and a pre-engineered building kit from General Steel provides the functional and aesthetic components that make your warehouse your own.

What is the difference between a warehouse and a distribution center?

The primary difference is distribution centers offer fulfillment services and warehouses offer storage space. Both can be profitable business investments.
