Many prefabricated, do-it-yourself metal carport kits come with a 20-year warranty on the steel frames. Among the metal carport kit manufacturers offering such warranties are Steel Factory Manufacturing, Absolute Steel, VersaTube Building Systems, Alan's Factory Outlet and CarportsAndMore.com. Alan's carport kits have a 30-day warranty on craftsmanship.
Absolute Steel uses 14-gauge steel and G90 galvanized sheets and guarantees its carport panels for 20 to 25 years from fading, cracking or peeling. VersaTube uses only pre-engineered American steel while Alan's uses 14-gauge steel tubes and 29-gauge metal sheet roofing. CarportsAndMore utilizes 12-gauge steel tubes.
For those without a garage, prefabricated carport kits are a quick and convenient way to protect vehicles against damage from the natural elements, such as the sun, wind, rain and snow. Easy to assemble using simple household tools and average human strength, carport kits come in a variety of sizes and colors, and many manufacturers customize to client specifications.
