This is a 18x21 Vertical Roof Carport that comes with 7 feet tall legs, 14-gauge tubing, and carport legs that are 5 feet on centers. Additionally, it has 2 feet corner braces and center brace on every leg. You can also buy extra bows separately. Truss upgrade is available. You can add taller leg columns to this carport to increase the clearance. We design custom carports up to 20 feet tall leg height. A 20 feet tall standard carport provides a center clearance of more than 23 feet, which is suitable for residential, commercial, and industrial use. You can also customize this carport by adding a gable or an extended gable on the front or back end. We offer extra sheet metal that you can use to partially close the sides or ends of the carport, depending on your needs and usage. You can also choose to close one end or both sides.

18x21 Metal Carport

This 18x21 prefabricated metal carport can be installed on your level lot or existing concrete slab. Our custom metal carport prices vary by the state where they are installed. Our contracted crew can install a carport on concrete, gravel, asphalt, or ground. We can also install a carport over a deck or a 3′ wall, but that entails some extra charges. You can call us to ask about installing a carport over an existing wall; this will require additional labor charges.

In most states, our metal carports with the Standard 14-gauge Steel Frame are certified for up to 140 MPH Wind Speed and 35 PSF Snow Load. We offer up to 90 PSF Snow Load Certifications for an additional charge in any state we service. We also build upgraded carports using 12 GA tubing material. Our 29 GA sheet panels come with a 20-year Limited Rust-Through Warranty and a 90-day Workmanship Warranty on Installation.

This 18x21 Steel Carport can be installed in areas where the local codes do not exceed 140 mph wind gust speeds. We can build you a carport that can withstand up to 170 mph of wind certification 3-second wind gust with our optional wind certification which covers most of the coastal United States. You can now order any custom metal carport from the ease of your home or office and choose from the 13 different color options. Our carport colors can be customized on the roof, trim, on the walls (if you choose to enclose it), and you can even add a wainscot/two-tone to your enclosed building. Either your carport walls have a horizontal orientation or vertical, our two-tone package is perfect to increase the curb appeal of this metal structure giving it a premium look and feel.
