Abstract
A door having an appearance of being entirely made of wood which is provided by panels of wood veneer adhesively secured to a core of thin gauge sheet metal panels. The sheet metal panels are adapted for this purpose by being imparted with horizontal and vertical fold lines which enable the panels to resist flexing and bending out of plane, to thereby contribute to anti-warping and other noteworthy features.
