Why choose a prefab steel garage?

Steel-framed garages constructed with rigid I-beams provide a sturdy, cost-effective, and easy-to-maintain alternative to conventional wood structures.

Our prefabricated kits enable a completely open clearspan layout, eliminating the need for internal support pillars and ensuring every inch of the floor space is usable. The buildings feature a roof without trusses, increasing the height for additional storage, a workspace, or a residential apartment.

The commercial-grade steel roof framing is designed to bear extra weight, perfect for fitting a winch or crane, making them ideally suited as auto maintenance shops.

The precision-engineered parts ensure a smooth build process, substantially reducing construction time. The bolt-together framing system enables fast setup with zero material waste.

Unlike basic tube-framed buildings, our pro-grade buildings are built to last, weather any storm, and add value to your property.

Moreover, they are engineered to meet all local building codes and can be officially approved for occupancy, providing the flexibility to incorporate living spaces if desired.

How location affects your 40' x 60' garage price

The geographical location of your new structure will impact the design and cost of your 40' x 60' metal building. Our team of engineers will take into account the weather conditions in your area to ensure that the building is designed to withstand the wind speeds and snow loads that are common in your area.

Our suppliers will also ensure that the metal building meets all the necessary code requirements for your area so you can be confident that your project is safe and up to standard.

Site preparation and foundation

Before the delivery of your building kit, it is crucial to obtain the necessary construction permits and prepare the site where the building will be erected. Once you have confirmed that the site is clear and level, the next step is to lay a concrete slab foundation.

For most garages, a 4-inch slab is sufficient, but it is recommended to opt for a 6-inch thick foundation if you plan to store large trucks or substantial machinery or install car lifts.

Installation / construction

A local steel erection company commonly assembles our 40' x 60' garages. Construction typically takes four to six days for a structure of this size.

If you have prior experience in construction and the assistance of two or three skilled friends, undertaking a DIY build is also feasible. Should you choose this path, be aware that you'll need to rent equipment for lifting the structural columns and roof rafters.

If speed of construction is a primary concern, you might want to hire a local general contractor (GC) to facilitate the build. A GC will coordinate the project, engage subcontractors, and oversee the entire project. It is recommended that 20% of the total project cost be allocated for a general contractor's services.

Garage insulation

Suitable insulation must be installed in your metal building to maintain an ideal temperature and prevent moisture buildup. Moisture can lead to corrosion, which can harm the structural integrity and visual appeal of your building.

To insulate a 40' x 60' steel garage with vinyl-faced fiberglass, you can expect to spend anywhere from $4,200 to $8,500, depending on factors such as building height, material quality, and local labor rates.

Common questions

  • how many cars can fit in a 40' x 60' garage?

    A garage measuring 40 feet by 60 feet has a floor space of 2,400 square feet, which can store up to six cars or trucks comfortably. On the other hand, it can house up to twelve vehicles for long-term storage or a growing car collection.

  • How much does it cost to add lean to a metal building?

    A lean-to addition typically costs $8 to $12 per square foot. So, for a 10' wide by 10" high lean-to at 40 feet in length, you can expect to pay between $3,200 and $4,800.

  • How do you add a loft space to a 40' x 60' garage?

    If you are looking to add a loft to your garage there are two main options available. You can install a steel-framed mezzanine level. These can be engineered and supplied by your building kit supplier. Mezzanines typically span one or more bays of 20 or 30 feet. Another option would be to frame the interior of the building with traditional 2x4 lumber or steel steel studs.
