Sheltering your camper with a metal RV carport doesn’t have to break the bank. The lasting protection from carports and garages goes beyond preventing weather damage. They can keep your RV looking better and running longer. That way, you’re free to spend more time doing what you love with a more reliable camper.

Our team cuts no corners. We use materials and certifications that meet all state requirements, and make sure you know exactly what your carport or garage will look like inside and out.

Open Metal RV Carports

The most streamlined version of metal camper carports, the open carport design offers a strong roof and frame without wall panels. This approach offers the lowest cost to placing a roof over your RV. Open sides can limit overall protection, but the Alpha Structures' commitment to quality ensures the cover will withstand both mother nature and the test of time.

Enclosed Metal RV Carports (RV Garage)

Metal RV carports and garages offer full enclosure protection, shielding valuable campers from creatures and the elements. These robust buildings withstand hail, snow, rains, and wind. That way, the RV doesn't have to. Make sure your camper is ready to go when you are with a fully enclosed metal RV carport.

Metal Garage for RV with Lean-To

This structure expands the functionality of a metal garage for RVs by adding 1 or 2 lean-tos. Whether the central RV storage area is open or enclosed with walls, lean-tos extend the roof for additional coverage. Protect your RV in a dedicated metal garage, and store other equipment or vehicles under an attached roof at a highly efficient price.

Metal Garage with Attached RV Carport Lean-To

If you’re considering an open carport for RVs, an upgraded car garage with an attached lean-to offers unmatched pricing efficiency. A new garage for your vehicles provides extra storage space while an attached lean-to covers the camper. And with the toughness of Alpha Structures, your new garage and attached camper carport will last decades.

Metal Building Sizes

Width is the primary factor in building size. Our clear span custom metal buildings can be up to 70 feet wide and as long as you need. Wider buildings are also possible with interior support beams.

Support Beams

12’ - 24’ wide

Support beams on the outer walls every 5 feet (excluding doors). Clear span option available. No length restriction.

25’ - 70’ wide

Support beams on the outer walls every 4 feet (excluding doors). Clear span option available. No length restriction. A heavier metal gauge truss allows for extra width without the need for center support beams or compromising structural integrity.

If you're not sure of the exact building size you'll need, no problem. We work with property owners every day to nail down the perfect balance between square footage and price for them. To get you started, here are a few examples of common custom metal building sizes.

Building Materials and Certifications

Insulation - Metal Garage for RV

The recommended metal garage insulation levels depend on your location and intended usage of the structure. We provide the option for up to an R-8 fiberglass batt down to a “sweat preventer” that stops condensation from forming on a regular basis. Basic do-it-yourself air sealing can have a big impact while keeping prices aggressively low. Alternatively, local insulation contractors can provide any level and type of insulation in our buildings.


Trusses and support beams are 14 gauge double-coated galvanized steel. In wider building designs, 12 gauge trusses may be necessary. Weight-bearing framing is guaranteed to last 20 years without developing any rust (ask about our rust warranty for details). 

Roof and Wall Panels

We offer a variety of metal panels ranging in size, ribbing, and color to best fit the structure. These panels are rated to last at least as long as the framing. Our installation teams use horizontal siding to give the buildings a distinct look. We also offer vertical siding for buildings that need extra support.

Weather Rating

Building codes vary across different regions, and we know exactly what each state requires. Our buildings can withstand 120mph wind gusts and 20psf of snow load. Even if your local codes require additional strength, we will meet or exceed them.

Building Permits

We don’t work directly with local building inspection offices, but we make the process easy for you. Our team will provide all the required documents to get your building permit on the first submission. We pride ourselves on making our customers and inspectors happy with our attention to detail.

Why Alpha Structures?

You want a metal building that’s tough enough to withstand the test of time and mother nature. You also want a builder that’s easy to work with and responsive to your questions.

Our team will work closely with you throughout the entire process to make sure you are confident and comfortable with the final design. You’ll receive a 3D model of your building before we start work, making sure it satisfies your vision.

We focus on the people we serve just as much as the buildings we put together.
