This disclosure relates to a composite structural member comprising a body part and multiple rigid strips which are attached to and separated by the body part. The body part is formed by a core having substantially flat parallel sides and opposed edges, and the opposed edges are covered by the rigid strips. As an example, the core is made of gypsum, and the strips are made of sheet metal. The rigid strips enable screw fasteners to be secured to the structural member. The sides of the core are preferably covered by side sheets.

[ What is claimed is:] [1.] A structural member for supporting at least one board comprising a nonheat conducting core member, said core member having first and second spaced apart sides and first and second spaced apart edge surfaces, the spacing between said first and second edge surfaces being at least as large as the spacing between said first and second sides, and a non-metallic flexible cover sheet, said flexible cover sheet covering said first side, overlapping each of said edge surfaces and having an overlapping portion covering at least a portion of said second side, said cover sheet in cooperation with said core impeding bending of the structural member in response to a load directed perpendicular to the edge surfaces when the structural member is attached to the at least one board with said flexible cover sheet positioned adjacent to said at least one board.
