Find a Wide Range of Large Steel Building Sizes at Great Prices

At Alan’s Factory Outlet, we carry a large selection of prefab metal carports and large metal buildings, and we can also customize one to just about any size you’d like. Our stock metal garage lengths range from 20 to 48 feet long, and you can buy a large metal garage that’s between 32 and 60 feet wide. But for those who need extra-large storage buildings, we can also connect metal carport buildings end to end to make even larger sizes. We can even build you an extra-large metal shed up to 60 by 100 feet! No matter how much storage space you need, at Alan’s Factory Outlet, you can find sturdy, reasonably priced, large portable storage buildings that fit the bill.

Large Portable Buildings That Hold Up in Snow and Wind

All of our 32-to-60-foot-wide large prefabricated buildings and carports have a vertical roof design that allows snow to slide off of the roof instead of weighing down your building. And sides and ends can be put on any carport, even the largest models, to create fully enclosed portable storage buildings that can protect your property from anything the weather can dish out.

Each large steel building has a special truss support at each bow. This makes them rated for either 170 mph wind and 35 pounds per square foot of snow or a heavy snow load of 65 psf and 105 mph winds, depending on your local code.

Sizes and Specs of Large Metal Sheds and Carports

These large metal storage buildings can be built with 14-gauge steel tubing or a thicker 12-gauge steel tubing. The framing comes with a 20-year rust-through warranty to ensure that these metal carports are long-lasting. Our 32-to-60-foot-wide metal buildings are anchored for free to your level concrete pad with cement anchors or to the ground with mobile home anchors. The side height on these steel buildings comes standard with 8-foot legs but can be made taller with a 10-, 12-, 14-, 16-, 18-, or 20-foot-tall side height if you need an extra-large metal shed size.

Our 32-to-60-foot-wide metal buildings come standard with vertical sides and vertical ends. For the same price, you can get your steel building made with lap siding, like the red-and-while metal garage shown below, upon request. Lap siding is still metal siding, but its placement mimics the look of vinyl siding.

What Are Carports Made Of?

Any unenclosed carport or large garage for sale in our shop will be made of sturdy corrugated steel. This is the best option for a strong structure that will hold up through years of weather. Steel is also fire-resistant and resists damage from mold and bugs, offering reliable protection for vehicles and other property inside.

Do Metal Carports Require a Permit?

You’re likely to need a permit for any large structure, but it depends on the size of your carport or garage and your area zoning laws. Many places only require a permit for buildings of a specific size, so you will likely need one if you’re planning on installing a large metal garage. Check your local laws to find out the requirements in your area. They can often be found on your municipality’s website.

How Much Do Carports Cost?

You can expect to pay between $5,695 for a 32×20 carport and $17,995 for a 60×40 carport with 8-foot legs fully open. Prices will vary based on the specific size, your location, and the features of your structure. You can explore our price charts for more information or contact us for an estimate.
