Corner braces are U-shaped channels that are used to assist in reinforcing the structure of the building. On all of our building, four 2’ long corner braces come standard, and are installed on each corner of the building. Additional corner braces are available at additional cost. We recommend the use of 2’ long corner braces on each building leg (2 per bow). For buildings with legs that are longer than 8’ , we recommend that customers upgrade to 4’ corner braces on each corner, and we also recommend that they be installed on each building leg (2 per bow).
