Abstract: A metal building frame and method for its assembly is disclosed. The building frame includes channel shaped structural members which are utilized for rafters, girders, and vertical columns. The various structural members are joined together by specially designed joining clips which provide structural strength and ease of assembly. Each of the clips includes a channel shape member into which one of the structural members can be inserted and bolted in place. Ridge clips join two of the rafters and are joined together at a preselected angle to define the roofline of the building. A rafter clip is attached to the top of each of the vertical columns and includes and angled portion which is bolted to the outer end of each of the rafters at an angle which is consistent with the preselected angle. The lower end of each vertical column is bolted to a base clip which in turn provides a base member which may be bolted to the floor of the building.
