Double Cars Metal Carport has a dimension of 18’W x 21’L x 7’H. If you need an affordable shelter for your vehicles, then look no further. The featured metal carport gives an easily accessible route to your belongings.

That easy accessibility, however, does not compromise the protection that your valuables receive. You no longer have to leave your vehicles or other equipment to suffer damages because of the weather.

This prefab steel carport will protect your valuables from harsh sun exposure as well as from heavy snowfall. Other constructions, like wooden carports, can give you headaches with maintenance.

This metal carport, on the other hand, pretty much takes care of itself. It has a very long lifespan and does not require great repairs or replacements during its lifetime.

While we sell this structure as a metal carport, it is much more than that. It can serve as the perfect outdoor storage shelter for utility tools, farm equipment, and much more.

You can even store go-carts under the roof of this steel carport, just like in the picture. The carport can also provide a workspace where you can practice wood-working or conduct repair of your automobiles, etc.

Features of 18×21 Boxed Eave Double Cars Metal Carport

There are a few basic elements that form the structural composition of the pictured metal carport. The roof of the prefab building has a traditional, two-way sloping, and an A-framed roof structure. Over this structure are the horizontal roof panels.

This roof panel does a great job of resisting moderate elements. For more heavier weather loads or for heavy precipitation, our customers can upgrade to vertical roofs.

The main framework of the metal carport is entirely made from 14-gauge steel tubes. Again, we also offer a stronger option of 12-gauge tubular framing at an additional cost.

This metal carport also has some partial coverage which adds extra protection. The right wall of the carport is fully covered with horizontal panels.

Also, the open ends give maximum clearance for your vehicles and equipment. Additionally, options are also available to cover the metal building entirely if you want complete security for your belongings.
