Featuring metal units that range from basic single and double carports, triple-wide metal carports, RV covers, motor home carports, fifth-wheel shelters, loafing sheds, barns and much more. All of our metal buildings feature heavy-gauge, galvanized steel construction for durability. Our standard configuration is 29 gauge roof metal with a 14 gauge tubular steel frame. If you live in an area that receives heavy wind, and rain you might consider upgrading to the stronger 12 gauge steel frame.
