A structural panel includes a frame having one or more attachment members. A material injection-molded onto at least a portion of the frame fills one or more openings at least partly defined by the frame and defines at least a portion of a shape of the panel. The attachment member(s) are at least partially embedded in the injection-molded material for attaching the panel relative to the structure. Because attachment members can be embedded in this panel, little if any post-processing is needed to install the panel.
