ABSTRACT:
A metal roof truss assembly is provided comprising a plurality of elongated structural members, including a top chord, a bottom chord, and a web member. Each structural member comprises a planar base and planar legs extending from the longitudinal edges of the base. The base and the legs define an open longitudinal channel. A flange integral with the longitudinal edges of each leg has a planar first portion extending outwardly from the legs and a planar second portion extending from the longitudinal edges of the first portion of the flanges. The end of a first structural member is inserted into the channel defined by the legs and the base of a second structural member. The inserted end of the first structural member has no flanges for a length equal to at least the depth to which the first structural member is received in the channel of the second structural member so that the outer surface of the legs of the first structural member are adjacent the inner surface of the legs of the second structural member.
