Abstract
A platelike structural panel is disclosed having spaced surfaces with a foamed core material therebetween. The surfaces are formed of sheet metal plates having adjacent longitudinal edges which are bent so as to form grooved seams joining and locking the plates together. The surfaces may be formed by continuously joining and seaming sheet metal from a coil and the foamed core may be formed by foaming the material between the joined plates or by gluing already foamed material between the plates.
