Abstract: An apparatus and associated method for a header in a structural framing system comprising a pair of track members defining opposing receiving portions. A plurality of column members is disposed substantially transversely to the track members and joined thereto. A web member is receivingly engaged in the receiving portions and spans the column members. The track members can be characteristically longitudinally arcuate and the web member characteristically conformable to the arcuate shape of the track members. In one illustrative embodiment the track members can comprise a plurality of flexibly joined sections that are moveable to define a selected arcuate longitudinal shape. A retaining member is adapted for retaining the flexibly joined sections in the selected shape. A fixing member is adapted for fixing the web member to one or more column members and/or one or more of the track members after the track members achieve the selected shape.
