Roof bracing is a pre punched v shaped component that fixes in an x or v pattern to the top of the top chord to firmly brace roof trusses to the building frame. Such bracing allows the buckling length of the bottom chord to be limited out of the plane of the truss to the distance between points laterally restrained.

To strengthen the roof system truss clustering cross bracing and wind bracing is recommended at both end of the buildings and every 20 for longer span buildings.
