Our most economical option is the 14 gauge steel framing. This is the industry standard, measuring 2 ¼” x 2 ¼” in diameter.    The lower the gauge, the thicker and stronger the material. Our 12-gauge framing is 2 ½” x 2 ½” in diameter and has a higher tensile strength that provides higher snow load and wind load ratings. That’s why we recommend the 12-gauge steel for areas with heavy snow and high winds, as well as carports 10’ and taller.   The 14-gauge steel is the industry standard of frame thickness and the nationally accepted gauge for carports, RV carports and other metal structures. Both gauge options are structurally sound and will allow you to use the metal structure safely. All of our gauge options can be certified, but we can only offer our extended warranty when you select the 12-gauge steel option.
