Braces are U-shaped channels used to assist in reinforcing the structure of the building. Our buildings come standard with some type of bracing, depending on the building purchased. For those buildings in which bracing is optional, we recommend 2-foot braces on buildings eight feet or less and 3-foot braces on buildings nine feet or more. Both our 2.25-inch and 2.5-inch braces are constructed from 18-gauge steel and are compatible with all Eagle carports and our competitors' frames, as well.
