At CarportUS.com, we want to make sure your prefabricated building is as secure as possible. To that end, we require 4’ braces when the leg height is 8’ or taller on carports, metal garages, RV carports, and any other building that is not fully enclosed.     We include them on all certified structures that are not fully enclosed. Any triple wide building purchased through CarportUS.com also includes the 4’ braces at no extra charge.
