Features of 18×21 Vertical Roof Double Car Carport

More than any other structure, the framework of this metal carport is mostly known for its structural stability. For the info, it consists of 14-gauge tubular framing and the horizontal panels covering the roof.

14-gauge steel tubes are handy in providing resistance against the elements. But with this metal carport, you also get an option to choose the 12-gauge framing. By the way, 12-gauge tubes have greater thickness and consequently greater structural strength.

Additionally, you’ll be provided with various customization options with this metal carport. Besides the dimensions and the colors, you can also choose how much coverage you want for your carport.

For a more enclosed carport, you can choose to add side or end panels and the gables. Alternatively, you can also wholly enclose the carport to turn it into a garage as well.

At Carport1, you can customize the metal carports or any other metal buildings the way you want. So, with this metal carport too, we provide a wide range of modifying features. Besides dimensions, you can change the color, the metal framing, coverage, etc. of this carport.
