Overview:

Anti sag support for Eaves Beams is provided by Eaves Struts in conjunction with Eaves Strut Cleats and Eaves Strut to Purlin Cleats and all supported off a rigid structural member such as the cold-rolled sections shown in the images below. Where these are used, connection may be to the bottom flange or the centre web. The preferred option is connection to the web centre as risk of torsion of the cold-rolled member under load is less likely. This option does however require much free space, unobstructed by building members such as tie beams or insulated gutters. Where the path of the Eave Strut is obstructed the alternative arrangement may be considered.
